Jabsco Hy~Line and Ultima
Rotary Lobe Pumps
Installation Operating and
Maintenance Manual
1. INTRODUCTION
Hy~Line and Ultima are positive
displacement rotary lobe pumps designed to
pump delicate, viscous and particle-laden
fluids as well as thin liquids which require an
all stainless steel pump. They share many
common features but the construction of
Ultima differs to provide an exceptionally
high standard of hygiene and cleanability.
This entire manual applies to both pump
ranges, except:
It is essential that anyone who will install,
operate, or be involved with this equipment
shall read the whole of this manual before
installing the pump, as it contains
important safety information. Failure to
follow these instructions could result in
damage to the pump or injury to yourself
or other people.
Adherence to the procedures and
specifications outlined in the following
chapters will assist in providing economical
and reliable operation throughout the life of
the pump.
If service or repair other than that described
in this manual should become necessary,
contact your supplier for assistance.
Any pump returned to the supplier for any
reason must be fully cleaned and
decontaminated and accompanied by
details of what fluids have been pumped,
including full Health and Safety information
(MSDS sheets) if any of those fluids are
hazardous.
All figures in brackets ( ) throughout this
manual refer to the component key numbers
used on the cross-sectional drawings and
the spare parts lists.
1.01 SAFETY
Throughout this manual your attention is
drawn to certain procedures which must be
followed to ensure safe operation and
servicing of this product.
DO NOT ignore safety instructions.
DO NOT remove, by-pass or tamper
with safety devices.
DO NOT use this equipment if the
end cover (122) is removed, guards
are missing or inlet & outlet
pipework is not connected.
DO NOT forget the hazards of
moving parts, high fluid pressure,
extremes of temperature,
hazardous liquids, electricity.
Always isolate and lock-out pump
drive motor before inspecting or
servicing pump.

1.02 PRINCIPLE OF OPERATION
Hy~Line and Ultima pumps have 2 rotors
which turn in opposite directions. Fluid
enters the pump from the inlet port and fills
the space between the rotors. This fluid is
carried around the outside of the rotors and
is forced out of the discharge port as the
rotor lobes mesh together see Figure 1.
Each rotor is supported on a shaft and when
the pump is running within its operating
limits, the rotors never touch the inside of
the rotor case, or each other.
1.03 OPERATING CONDITIONS
Hy~Line and Ultima pumps are designed
using modern design techniques and
manufactured from high quality materials.
However, there are certain limitations to the
operating conditions of the pump to ensure
long life and trouble-free running. During
pump selection and specification these
limitations are taken into account and must
not be exceeded.
Every pump is supplied with a Performance
Data Sheet which gives details of these
limitations. These are:-
Maximum Pressure
Maximum Temperature
Maximum Viscosity
Maximum Particle Size
Maximum Speed
Maximum Input Shaft Torque
Maximum Input Shaft Radial Load
These limitations and performance
characteristics vary from one pump size to
another, and from one pump specification to
another within the same pump size.
Take particular care over the following:-
Materials: Ensure that all the fluids to be
pumped, including cleaning and sterilizing
agents, are compatible with the materials
from which the pump is constructed.
See section 2.10 for details of shaft or seal
types and section 2.11 for alternative seal
materials, i.e. seal faces and elastomers.

Operation
(Showing

Mounting)

Hy~Line and Ultima pumps can be used for
duties other than those for which each pump
was originally selected but the new
application must be checked against the
Performance Data Sheet to ensure safe and
reliable operation. Unless you have
experience in the use of this Data Sheet, we
strongly recommend that, if a change of duty
is required, you contact the distributor who
supplied the unit or the manufacturer.
Change of duty means changing any of the
parameters listed above.
1.04 MODEL NUMBERING SYSTEM
A metal plate is fixed to the pump showing
model number and serial number.
The MODEL NUMBER gives important
information about the specification of the
pump, see Section 8 for details. It is
important that the pump specification is
established using Section 8 before any work
is carried out on the pump or parts are
ordered.
The SERIAL NUMBER is unique to each
pump.
Both numbers should be quoted with all
queries or orders for spares.
1.05 INSPECTION UPON RECEIPT
All Hy~Line and Ultima pumps are factory
inspected and tested before packing and
shipping, to ensure safe delivery and
satisfactory service. We would, however,
recommend that you carry out the following
actions upon receipt of your lobe pump:-
a) Remove packing material from
container and check contents against
packing list. Look carefully for small
parts and special tools included.
b) Check the pump for any physical
damage sustained in shipping. If loss
or damage is found, notify your
carrier and supplier immediately.
c) Use lifting equipment as necessary
when unpacking heavy items. See
Performance Data Sheet for weights
of bareshaft pumps. Drives and
baseplates will increase weight
above those shown.

2. INSTALLATION
Careful attention to correct installation of
Hy~Line and Ultima lobe pumps, and
recognition of certain limitations to the
operating conditions of the pump, will
ensure long life and trouble-free running.
Failure to follow these instructions
could result in personal injury or
loss of life. Take particular care over
the following:-
2.01 OPERATING LIMITATIONS
PRIMING: Hy~Line and Ultima pumps are
not truly self-priming and should be installed
in a “flooded inlet” pipe arrangement i.e. with
the pump lower than the level of liquid to be
pumped and with the supply pipe falling
continuously to the pump with no loops.
PRESSURE: Do not operate the pump
above the maximum differential pressure
shown on the Performance Data Sheet, not
even for a few seconds, as damage to the
pump components will result, leading to
metal particles in the pumped fluid,
ineffective cleaning and possibly complete
pump seizure.
NEVER run the pump against a closed
valve. Note that the pressure limit
varies with temperature.
SOLIDS: Hy~Line and Ultima lobe pumps
can handle soft solids in suspension but will
be damaged by hard particles. Take care
pumping solids, crystals, etc.
Never allow metal parts to enter pump, e.g.
weld metal, screws, tools, etc. as these will
stop the pump, leading to damaged rotors,
rotorcase and shafts.
CAVITATION: The pumps cannot operate
without sufficient pressure of liquid at the
inlet port to supply the pump. Normally
atmospheric pressure is sufficient but the
actual pressure needed (Nett Inlet Pressure
Required or NIPR), is higher for:-
High Viscosities
High Temperature
High Pump Speeds
Volatile Liquids
Insufficient inlet pressure will cause the
pump to cavitate leading to low
performance, noise and short pump life.
Ensure inlet pipes are short, large bore and
do not collapse under vacuum. Refer to
Performance Data Sheet for Nett Inlet
Pressure Required (NIPR) charts. If in doubt
consult your supplier before operating the
pump.
2.02 LOCATION & POSITIONING
Pump should be located:
• As close as possible to the fluid source
and as low as possible to maximize the
nett inlet pressure available to the pump.
• In a clear area allowing access all around
pump and drive for easy servicing.
• With space above for lifting equipment if
required.
• With port axis vertical if pump is required
to be self draining.

Hy~Line and Ultima Lobe Pumps
07/03

All Hy~Line and Ultima pumps are equally
suitable for both directions of rotation.
Hy~Line and Ultima lobe (not LH32 or
LH34) pumps can be rotated to give vertical
or horizontal port orientation with high/low or
left/right input shaft positions. This is
achieved with the bolt-on feet and
re-positionable gear cover. (see Figure 2)
To change any pump from vertical to
horizontal pipework or vice versa, a
conversion kit containing the required feet
and other components is available.
To convert a pump from high shaft to low
shaft, it is necessary only to reverse the feet
and timing gear cover positions as follows:-
Foot Change
Remove key (29) from the drive shaft end.
Remove the 2 bolts (18) from the gear cover
(11) and slide the cover off of the shaft end,
being careful not to damage the inside of the
lip seal on the edges of the keyway in the
shaft. Rotate the cover to the desired
position and re-fit. It is wise to fit new sealing
washers (19) to the heads of the bolts
before re-fitting. Remove the 4 retaining
screws (21) from the feet and re-position the
feet in the desired position. Re-fit the bolts.
For LH72, 74, 76 Pumps - Replacement
feet for vertical seal.
For LH32 and LH34 Pumps:
The LH32 and LH34 size pumps are factory
built with HORIZONTAL PORT orientation
with top shaft position. They cannot be
modified for alternative mountings. To
enable VERTICAL PORT orientation it will
be necessary to mount the pump on an
angle bracket (‘L’-Bracket). A special gear
cover will be required.

2.03 DRIVES
Hy~Line and Ultima lobe pumps can be
supplied in bareshaft form i.e. without a
drive motor. Drives must be selected and
supplied to suit each individual application.
The prime mover will most likely be an
electric motor but hydraulic or air motors
may also be suitable.
Pay attention to special motor requirements.
e.g. Explosion/flame proof
Hose proof/splash proof
High ambient temperature
Frequent stop/starts
Materials of construction
Provision of a variable motor speed (e.g. by
frequency inverter), is always recommended
to enable flow to be accurately set, to
accommodate changes in fluid viscosity,
temperature or required flow rate, or to run
pump faster for cleaning. Variable speed
motors must selected to accommodate the
full power and torque requirements
throughout the operating speed range.
Transmission to the pump shaft will normally
be by one of the following:
a) Direct Coupling: If synchronous motor
speeds can be matched to the required
pump speed, the drive can be via a
proprietary flexible shaft coupling. A torque
limiting coupling can protect the pump
against overload.
In all cases the coupling manufacturer’s
limits should be adhered to. See
Performance Data Sheet to calculate
torque. Pump and motor shafts should be
accurately aligned in accordance with the
coupling manufacturer’s instructions.
Ultima only: When providing drives for
Ultima pumps it is important to note that the
rotors (57) are retained by tie-rods (26 & 27)
which fit through the hollow shafts (24 & 25).
Careful consideration should be made when
installing drives and couplings so that
access to the tie-rod nuts (87) and tie-rods is
readily available for maintenance purposes.
Use of a spacer type coupling is
recommended.
b) Reduction Gearbox: For pump speeds
lower than synchronous motor speeds, a
proprietary gearbox or geared motor may be
fitted. Variable ratio units are available to
allow pump speed to be adjusted. Coupling
to the pump will be as in (a) above.
2.04 BASEPLATE
The pump and drive will normally be
mounted on a common baseplate or frame
which must be strong and rigid enough to
withstand the drive reaction forces as well
as to support the equipment without
vibration. Ensure base is level - distortion
could affect coupling alignment. Always
check pump to drive alignment after
installation and before starting pump. For
maximum hygiene the pump feet should be
sealed to the base.

07/03
Maximum shaft radial load stated on
Performance Data Sheet must not be
exceeded.

2.05 GUARDS AND SAFETY
All moving parts must be guarded. Local
safety regulations and codes of practice will
specify the minimum acceptable standard
but as a guide:
• Couplings, belts and pulleys must be
enclosed to prevent fingers, clothing or
tools from touching moving parts.
• Guards must be made from corrosion
resistant materials.
• Guards in hazardous areas must be
made from non -sparking material.
• Guards must be securely fixed.
• Pump must not be operated with guards
removed.
2.06 ELECTRICAL
Electricity can cause injury or death -
follow good practice and local regulations.
In particular: -
Connect electric motor in
accordance with the manufacturer’s
recommendations.
All electrical work must be carried
out by competent personnel to local
safety regulations and codes of
practice.
Take special note of requirements of
the area, e.g. hose-down, high
humidity, explosion proof, etc.
Provide facility to isolate motor
during maintenance, service and
cleaning of pump.
Ensure motor rating plate
corresponds to supply.
Ensure rating of motor and controls
are adequate for duty, especially if
application details have changed
from original specification - see
Performance Curves to calculate
power.
Allow for exceptional circumstances,
e.g. cold start-up.
Provide adequate motor overload
protection.
Page 7
Hy~Line and Ultima Lobe Pumps
07/03

2.07 PIPEWORK
Pipe runs and sizes should be established at
the time the pump is selected. When
installing pump do not deviate from this
design without rechecking pump selection:-
• Keep pipe runs short and pipe diameters
large; pipes may need to be larger
diameter than pump ports especially
when pumping viscous liquids.
• Inlet pipe must be as short as possible
and as large as possible to prevent
cavitation.
• Use large radius bends and full bore
valves. Avoids globe or needle valves on
viscous fluids.
• Fit isolation valves each side of the pump
to simplify maintenance.
• Fit vacuum/pressure gauges each side of
pump to monitor pressure conditions.
Once process is established (and will not
change), these can be removed.
• Avoid filters on the inlet side of pump if
possible. A clogged filter will cause
cavitation. A strainer - maximum hole size
50 microns - will help to protect pump
from damage by particles but must be
kept clear.
• Support pipework - do not allow weight of
pipe (and the fluid within) to be taken on
pump ports.
• Fit expansion joints if necessary to
prevent thermal expansion forces being
transmitted to pump.
• Ensure all pipe joints are adequately
sealed to be a) Air-tight under vacuum b)
Liquid tight under pressure and c) Steam
tight where applicable.
• Take special precautions when pumping
hazardous, hot, toxic or bacteriological
fluids - special joints (e.g. aseptic) and
high specification seals may be required.
• Use hot water/steam jackets or electrical
resistance tape to heat pipes carrying
liquids which thicken when cool. Provide
an interlock to prevent pump from running
unless liquid in pipes is at correct
temperature to avoid over pressure,
cavitation. or excessive drive shaft loads.
2.08 ENLARGED RECTANGULAR INLET
The weight of the hopper (and the product it
contains) must be supported separately and
not allowed to rest entirely on the pump as
this would affect the rotor clearances
leading to pump seizure. The mating flange
of a hopper or screw feeder should be
machined to the identical dimensions of the
rectangular inlet and sealed. This will avoid
ledges where product could ‘hang up’.
Ensure effective flow of viscous material into
the pump.
Page 8
Hy~Line and Ultima Lobe Pumps
07/03

2.09 TEMPERATURE-CONTROL
JACKETS
Pumps are available with an optional
jacketed end cover (Pumps without end
cover pressure relief valve fitted), pump
head jackets fitted to top and bottom of
endcover (can be used with end cover
pressure relief valve) or jackets fitted to the
sides of the rotor case (Hy~Line pumps
only). These allow hot or chilled water, hot
oil or steam to be piped to the pump to
maintain product temperature in the pump or
to heat the pump prior to starting.
Application limits are:
Jacket Pressure: 2 bar (30 psi).
Temperature: 130ºC (265ºF).
2.10 SEALS AND FLUSHING
Three basic types of mechanical face shaft
seal are available on the Hy~Line and
Ultima pumps. The correct type should
have been selected when the pump was
originally selected but you must establish
that the seal fitted is suitable for the
application before starting pump. (See
Section 8.01 to identify seal type by pump
model number). Provide flushing system as
required.
There are also 3 types of seals which are
not mechanical face type, these are the
Single O-ring seal, Double O-ring seal
and the Multi Lip Seal.
Single O-ring Seals utilise a single Viton O-
ring on each shaft which are working under
dynamic conditions. This type of seal
requires a constant supply of pumped
product in order to avoid burning up of the
O-rings by dry running. They do not require
any additional services or special
installation. If dry running will be
experienced then the double O-ring seal
should be used. See below...
The Double O-ring Seal is similar to the
single O-ring seal, above, but have two
Viton O-rings per shaft. They can be treated
in the same way as a flushed mechanical
seal i.e. will need the provision of a flushing
system, See Flushed Mechanical Seals
below.
An alternative to flushing the Double O-ring
seal is to grease pack the area between the
O-rings. This ensures that the O-rings can
be run without product in the pump chamber
i.e. run dry, as they will be lubricated by the
grease. A method for 'topping up' the grease
will be required e.g. grease nipples.
Multi Lip Seals are supplied complete with
a grease injection system and require no
additional services.
The Single Mechanical Seal is suitable for
many clean fluids which do not require a
more sophisticated seal type. (See Figure
3).
Page 9
Hy~Line and Ultima Lobe Pumps
07/03
Figure 3:
Single
Mechanical
Seal

Note that code 2, silicon carbide-on-silicon
carbide, seals are not recommended for
steam-purged applications as the seal faces
can bind together - see Cleaning and
Sterilizing.
Pumps fitted with single seals require no
special installation but pumps must never be
run completely dry for more than 30
seconds, as this will cause excessive
heating of the seal faces. Use flushed seals
in pumps that need to run dry.
The Flushed Mechanical Seals fitted to
Hy~Line and Ultima pumps are run with a
low-pressure liquid flush between the
primary mechanical seal and a lip seal to
form a barrier between the pump and the
atmosphere. This allows the pump to be
used for applications where the single seal
is unsuitable.
Flushed seals are used when:
• Pumped fluid changes state in contact
with air, e.g. crystallises, forms a film,
dries out or precipitates solids. The flush
dissolves and rinses away the small
amount of reside which could build up on
the edges of the seal faces
• Pumped fluid is close to its boiling point
e.g. water over 80°C (175°F). The
flushing fluid is used to cool the seal
faces.
• Pumped fluid is temperature sensitive and
degrades when heated by the shearing
action of the seal faces. The flushing fluid
is used to cool the seal faces.
• Pump must run “dry”, i.e. no liquid in pump
chamber.
• Pump is under high vacuum.
• A low pressure sterile barrier is required.
A low-pressure flushing fluid system
must be installed as follows:-
• Liquid must be compatible with the
pumped fluid; water is the most commonly
used liquid.
• Pressure shall typically be 0.5 bar (7 psi)
gauge. Maximum of 1.0bar (14.5 psi)
gauge.
• Temperature shall be maximum of 70ºC
(160ºF) for water, less for volatile liquids
(maximum 20ºC (68ºF) below boiling point
of liquid).
• Flow rate shall preferably be 2 to 3
litres/min. (0.5 to 0.75 US gal/min) per
seal.
• Flush fluid should be connected to flow in
at the lowest point on the seal housing
and out at the highest point to vent air
pockets.
• Pipework should be as shown in the
diagram (see figure 4a).
Page 10
Hy~Line and Ultima Lobe Pumps
07/03
Figure 4:
Flushed
Single Seal

The double mechanical seals fitted to
Hy~Line and Ultima provide the facility to
contain a high pressure fluid behind the
primary seal. This allows the pump to be
used for applications where the single seal
is unsuitable. Double seals Codes 1 and 4
are run with a fluid between the primary and
secondary mechanical seals to form a
barrier between the pump and the
atmosphere.
For LH32 and LH34 Pumps:
Double mechanical shaft seals are not
available on the LH32 or LH34 size pumps.
They are used with:
Double Mechanical Seal with a low
pressure liquid flush when:
• The pumped fluid is toxic or hazardous
and must not escape from pump even in
minute quantities.
• The system can be installed as in figure
4a but must be capable of withstanding
the full pressure within the pumped fluid
pipe system.
Double Mechanical Seal with a high
pressure liquid flush when:
• The pumped fluid has no lubricating
properties and cannot be allowed onto
seal faces
• Pumped fluid is highly viscous, i.e. over
150,000 cps.
• A high pressure sterile liquid barrier is
required.
When the double seal is used with a high-
pressure liquid flush for the reasons
described above, a flushing system must be
installed as follows:
• The flushing liquid used must itself be
compatible with the pumped fluid and
must itself not require a complex seal, i.e.
must be non hazardous, non abrasive and
lubricating.
• Flush liquid must be at a pressure of 1 bar
(15psi) above the discharge pressure of
the Jabsco lobe pump and should flow at
35 to 55 litres/hour (10 to 15 US gal/hour)
per seal.
Page 11

• Flush fluid should be connected to flow in
at the lowest point on the seal housing
and out at the highest point to vent air
pockets.
See drawing for suggested liquid flush
system (see figure 5a).
Double Mechanical Seal with steam
when:
No bacteria or contamination can be allowed
to enter pump, i.e. an aseptic system. A
steam barrier system must be installed as
follows:
• Wherever possible, sterile liquid e.g.
steam condensate should be used as a
flush. Condensate should be connected
to flow in at the lowest point on the seal
housing and out at the highest point to
vent air pockets.
• Where steam is essential, great care must
be taken with the design of pipework,
steam traps and controls.
• Steam must be clean, filtered and wet, i.e.
not superheated.
• The pressure of steam should be as low
as possible consistent with the desired
temperature
• Steam should be connected in at the
highest point on the seal housing and out
at the lowest point to allow any
condensate to drain from the lowest point
• See figure 6 for suggested steam
connection.
Silicon carbide on silicon carbide
seals are not recommended for steam
flushed applications.

2.11 MECHANICAL SEAL MATERIALS
SEAL FACES
All primary seals are available with carbon-
on-silicone carbide faces (Codes 3, 4 or 5)
for non abrasive fluids and silicon carbide-
on-silicon carbide faces (Codes 1, 2 or 7) for
abrasive fluids containing crystals, powders
or particles or when no particles of wear can
be allowed to enter the pumped fluid.
Silicon carbide-on-silicon carbide (Code 1, 2
or 7) seals are not recommended for steam
flushed applications.
Hy~Line only: Carbon on stainless steel
single seals (Code 8) are available for non-
abrasive and lubricating fluids.
All secondary double mechanical seals
(Codes 1 or 4) are with carbon on silicon
carbide faces.
ELASTOMERS
Product contacting primary elastomers must
be selected to be compatible with the
product and the process operation.
Consideration must be given to chemical
compatibility, temperatures and material
standards. Hy~Line and Ultima are
available in a selection elastomers, see
below.
Consult supplier for more information.
2.12 END COVER RELIEF VALVE
Hy~Line pumps can be fitted with an end
cover relief valve which can be set to protect
the PUMP ONLY from overpressure. This
valve is not designed to protect the system
or to provide long term by-pass of liquid. If
this is required then an IN-LINE relief valve
should be fitted which can by-pass the liquid
back to the suction vessel during
overpressure situations.
The maximum pressure rating of the pump
is stated on the Performance Data Sheet.
The relief valve should be set so that is fully
open before it reaches this pressure. Be
aware that there may be a piece of
equipment in the system that is limited to a
lower pressure than the pump. If this is the
case then the pump end cover relief valve
should be set so that the pump cannot
exceed this pressure.
Setting the relief valve :
This should be done, if possible, using the
liquid to be pumped.
1. Screw the adjusting screw (135)
clockwise so that enters the housing as
far as possible. This ensures that the
valve is fully closed.
2. A pressure gauge is required to be fitted
in the pipe sysytem directly after the
pump.
3. Start the pump running.
4. Increase the pressure on the pump by
closing a valve downstream or by
increasing the pump speed. Continue
until the desired relief valve pressure
setting is achieved.
5. MAKE SURE THAT THE MAXIMUM
PRESSURE OF THE PUMP IS NOT
EXCEEDED. CHECK THE
PERFORMANCE DATA SHEET.

6. Start unscrewing the adjusting screw
(135) counter-clockwise until the
pressure gauge reading starts to drop.
7. If a small rod/pencil/pen is inserted into
the end of the adusting screw until it
contacts the end of the valve guide (134)
it is possible to feel the movement of the
valve.
The valve is now set.
8. Check the relief valve setting by opening
the downstream valve or reducing the
pump speed. It will be necessary to
reduce the pressure to approximately
10% of the set pressure to ensure full
closure of the relief valve. Alternatively
stop the pump.
9. Re-start the pump or increase the
pressure as before (see paragraph 4).
10.The relief valve should open at the set
pressure.
11.Make further adjustments as necessary.
2.13 END COVER BARRIER (CODE 5)
Ultima pumps may also be fitted with an end
cover to accommodate a barrier of sterile
liquid or steam. This offers additional
security when no bacteria or contamination
can be allowed to enter pump, i.e. an
aseptic system. (see figure 7)
Liquid Barriers: The flushing liquid used
must itself be compatible with the pumped
fluid. Fluid should be connected to flow in at
the lowest point on endcover and out at the
highest point to vent air pockets. Barrier fluid
maximum pressure for the end cover is
2 bar. (see figure 8).
Steam Barriers: The pressure of steam
should be as low as possible consistent with
the desired temperature. Steam should be
connected in at the highest point on the end
cover and out at the lowest point to allow
any condensate to drain from the lowest
point. (see figure 6).
2.14 OVERLOAD PROTECTION
To prevent injury to personnel or damage to
pump or system caused by excessive
pressures, a protection device should be
fitted such as:-

Cover

a) Pressure switch or sensor wired to stop
the drive motor. Ideally, the motor should be
fitted with a brake.
b) Pressure relief valve or bursting disc fitted
downstream of the pump and piped to direct
excess fluid away safely.
c) Pressure protection device fitted to pump
end cover. Hy~Line pumps can be ordered
with this already fitted or this can be ordered
from your supplier and easily fitted in place
of the standard pump end cover.
d) Torque limiting coupling between drive
and pump shaft.
e) Motor current sensor.
Note: The level of protection provided by
methods a) b) and c) above is superior to
that provided by methods d) and e) which
can be difficult to set accurately, especially
when pumping viscous fluids.
Protection devices must be set to operate
at, or below, the safe operating pressure of
the pump or of the system, whichever is the
lower. (See performance data sheet). Note
that maximum pressure varies with
temperature.
3. LUBRICATION
Jabsco Hy~Line and Ultima pumps have oil
lubricated shaft bearings and timing gears.
Pumps are supplied without oil in the
bearing housing.
Before starting they must be filled with any
of the following grades of oil, or equivalent
gear oil for the relevant ambient
temperature:
Examples: Shell: Vitrea , BP: Energol CS,
Castrol: Magna
Refer to Performance Data Sheet for oil
capacity.
• After the first 120 hours of service drain
the lubricating oil from the bearing
housing and refill with fresh oil of the
correct grade.
• Check oil level regularly and top up as
necessary. Any substantial oil losses
should be investigated immediately.
• Oil should be changed every 12 months
or 2500 hours running.
• When pumping hot liquids or when
bearing housing temperatures exceed
80ºC (180ºF) during operation use a high
temperature synthetic oil and change oil
every 6 months or 1000 hours running.

4. START UP & ROUTINE
CHECKS
4.01 START UP
Before starting pump for the first time or
after servicing or maintenance work, check
the following - failure to do so could damage
equipment or cause injury to personnel.
• All pump head and mounting bolts are
tight.
• All pipe connections are secure.
• All guards, safety and protection devices,
are in place and effective.
• Flushing fluid, if required, is flowing - see
Section 2.10.
• All valves are open - NEVER run pump
against a closed valve.
• Pipes and pump head, if heated, are to
normal operating temperature.
• Pump and pipes are clear of welding flash
or other debris.
NEVER use Hy~Line or Ultima pumps
to flush the system the first time. Flush
the whole system with suitable cleaning
agents before starting the Hy~Line or
Ultima pump, using another more
suitable pump if necessary. Be aware
that heavy or metal debris tends to
collect at the lowest point in the system.
• Pump is correctly lubricated - see
Section 3.
• Motor is wired for correct direction of
rotation - see Figure 9.
When possible, start pump slowly and
increase speed gradually.
• Listen for unexpected noises.
• Check for leaks.
• Check that pump gives desired flow rate
at normal operating speed.
• Do not continue to run pump if fluid is not
flowing; dry running can damage seals -
see Section 2.10.
• Observe pump during first few hours of
operation - check for noises and
excessive heating of pump bearing
housing, i.e. if above 80°C (176°F), unless
pumping hot liquids when 110°C (230°F)
may be reached.
• If operating at high speeds or with hot
liquids, surface temperatures can exceed
50°C (122°F), safety labels may be
required to comply with local safety
regulations.

All pumps and equipment surfaces
which become hot, i.e. above 60°C
(140°F), during operation should
carry warning labels.
4.02 DAILY CHECKS
• Visual checks of all joints for signs of
leakage of product, flushing liquid (if
used) and oil from the gearbox.
• Listen and look for any unusual noises,
vibration or temperature change.
• If minor problems are identified these
should be rectified at the end of the shift
and if major they should be attended to at
once.
4.03 WEEKLY CHECKS
• As Daily Checks.
• Remove end cover of pump and inspect
for signs of damage or wear. Repair or
replace as necessary.
• If the main product shaft seals are of the
O-ring type or multi lip seal type inspect
them for signs of wear. Replace or plan
for replacement as necessary.
• Check lubrication level and top up as
necessary. This must be done with the
pump stopped.
• Check lubrication level on drive unit and
top up as necessary. Follow the
manufacturer's instructions.
4.04 MONTHLY CHECKS
• As Weekly Checks.
• Remove end cover and rotors and
inspect seal faces for wear and condition
of elastomers. Replace as necessary or
note for planned maintenance.
• If an end cover relief valve is fitted check
its function. If the relief valve is not
operating on a regular basis the
diaphragm may have a tendency to stick.
4.05 SIX MONTHLY CHECKS
• As Monthly Checks.
• Change end cover O-ring (Hy~Line) or
end cover gasket (Ultima).
4.06 ANNUAL CHECKS
• Possible change mechanical seals if
fitted.
• Replace lip seal on mechanical seal flush
housings.
• Replace end cover relief valve
diaphragm.
• Change O-rings on O-ring type shaft
seals or lip seals on Multi lip type shaft
seals.
• Change all L-cups, O-rings and/or
gaskets on pump head.
• Inspect gearbox oil seals and gearcover
gasket for signs of leakage and replace
as necessary.
• Check bearing wear by seeing if there is
any movement of the shaft side to side or
forwards and backwards. If movement is
perceived remove gear cover and
dismantle bearings for inspection,
replace if necessary.
• Drain and change oil in pump gearbox.
By ensuring a visual inspection daily and
regular checks at planned intervals, pumps
can be maintained to maximum
performance for many years.

5. CLEANING &
STERILIZATION
Hy~Line and Ultima pumps are designed
for use with products that require the
process equipment and pumps to be
cleaned. The standard (level) of cleaning or
sanitization required depends on the needs
of the process and product. This information
is provided for guidance only. It is the
responsibility of the pump user to satisfy
him/herself that the cleaning protocol
chosen is adequate to achieve the desired
levels of cleanliness and Jabsco cannot
accept any responsibility for contamination
or loss.
In order to clean the pump it must either be
dismantled (manual cleaning), or cleaned in
place (CIP) as part of the procedure for
cleaning the entire process. The higher the
standard required, the more sophisticated
the cleaning process. Hy~Line pumps can
be cleaned and sterilised in place, i.e. by
flushing through with cleaning agents and/or
steam, without the need to dismantle pump.
Equally the pump can be quickly stripped to
gain access to all fluid contact surfaces for
manual cleaning or inspection if required.
Ultima pumps offer an exceptionally high
standard of in-place cleaning but are less
suitable for manual (strip) cleaning.
5.01 CLEANING IN PLACE (CIP) AND
MANUAL OR STRIP CLEANING
Cleaning Systems
The type of cleaning system used depends
partly on the level of cleaning required but
also on what is to be removed. Organic
materials such as oils, fats, proteins need a
different system to inorganic materials such
as mineral salts. Detergent manufacturers
can give advice on the correct use of
chemicals and temperature. CIP usually
needs a velocity of 1.5 m/sec (5 ft/sec)
through the pipeline to achieve the turbulent
flow required.
Procedure For Cleaning In Place (CIP)
Each pump is supplied in a generally clean
condition but it is the responsibility of the
user to establish suitable cleaning and
sterilizing regimes appropriate to the fluid
and process. These should be implemented
before the pump is first used and as often as
require thereafter. The following guidelines
will help with effective cleaning of both
Hy~Line and Ultima pumps and minimise
risk of damage to the pump.
1. Rinse through system with a suitable
liquid, usually water at approximately
50°C (120°F), as soon as possible
after completion of process to remove
bulk of residues before they dry onto
surfaces.
2. If CIP will not be carried out
immediately after rinsing, leave pump
and system full of rinse liquid.
3. Choose chemical cleaning agents to
suit the nature of the contamination to
be removed and use them in
accordance with manufacturer’s
recommended dilution, temperature
and circulation time but do not exceed
90°C (195°F). Confirm compatibility
with pump materials of construction.
