pedestal mounted or close-coupled units with capacities
to 100 GPM for other sanitary applications. Contact
factory for details.
OPERATING INSTRUCTIONS
1. INSTALLATION – Pump may be mounted in any
position. The rotation of the pump shaft determines
the location of the pump’s intake and discharge
ports. Refer to dimensional drawing. Pump is
normally assembled at factory for clockwise rotation
looking at end cover. If counterclockwise rotation is
desired, follow steps 1 and 2 of disassembly and
step 9 of assembly instructions to change direction
of impeller blade deflection under cam.
2. DRIVE – Belt or direct with flexible coupling. Belt
Drive: Overtight belt load will reduce pump bearing
life. Direct Drive: Clearance should be left between
drive shaft and pump shaft when installing coupling.
Always mount and align pump and drive shaft before
tightening the coupling set screw. If pulley or
coupling must be pressed on shaft, remove end
cover and impeller to support shaft from impeller end
during press operation. Do not hammer pulley or
coupling on shaft; this may damage bearing or seal.
Capacitor start motor is required to overcome
starting torque of impeller.
3. SPEEDS – 100 RPM to the maximum shown in the
performance curves. For longer pump life, operate
at lowest possible speeds. Lower speeds are
required for viscous liquids, consult the factory for
proper speeds and horsepower requirements.
4. SELF-PRIMING – Primes at low or high speeds. For
vertical dry suction lift of 10 feet, a minimum of 800
RPM is required. Pump will produce suction lift up to
22 feet when wet. BE SURE SUCTION LINES ARE
AIRTIGHT OR PUMP WILL NOT SELF-PRIME.
5. DISCHARGE - When transferring liquids further
than 25 feet, use 3" discharge line.
6. RUNNING DRY – Unit depends on liquid pumped
for lubrication. DO NOT RUN DRY for more than 30
seconds. Lack of liquid will damage the impeller.
7. PUMPAGE COMPATIBILITY – When corrosive
cleaning fluids are handled, pump life will be
prolonged if pump is flushed with a neutralizing
solution after each use or after each work day. A
Tungsten Carbide Seal variation is available for
pumping liquids that contain abrasives or are highly
corrosive.
8. PRESSURES – Consult Performance Curves for
maximum recommended pressures for pump in
continuous operation. If pressures exceed those
shown, consult the factory.
9. TEMPERATURES – The operating temperature limits
of the pump: 45° to 150° F (7° to 65° C).
N.B. 3A option to include Elastomers : EPDM and
Neoprene. Ports : Tri-Clamp, IDF, 3A and DIN11851.

10. CLEANING – Before using pump, it should be
disassembled and cleaned to remove any dust and
dirt resulting from storage or shipping. Wash parts in
standard cleaning solutions approved for handling
stainless steel. Thoroughly rinse before reassembly.
DO NOT USE IODINE BASED SANITIZERS as the
iodine attacks the elastomer materials used in the
impeller. All parts have been expertly machined and
polished. HANDLE WITH CARE. DO NOT DROP
OR MISHANDLE.
11. IMPELLER TORQUE – The torque required to
initiate rotation of a new impeller in a dry pump
body is:
Forward = 10.2 pounds force – feet
Reverse = 18.8 pounds force – feet
These values may vary slightly due to manufacturing
tolerances. Consult factory for more information.
12. SPARE PARTS – To avoid costly shutdowns, keep
a spare JABSCO impeller, seal and O-ring set
on hand.
MANUAL BY-PASS CIP ENDCOVER FOR
JABSCO PUMPS
Jabsco stainless-steel milk collection tanker pumps are
easily cleaned in place at the same time that the tanker
is cleaned. This can be achieved in 2 ways:
By running the pump to circulate the cleaning liquid
through the pipe work and metering equipment; a
separate land-based CIP pump may be used to provide
the pressure to the tank spray balls. The pump and
impeller can withstand hot water and proprietary
chemicals for the duration of the cleaning cycle.
Alternatively, if the pump is fitted with the Jabsco Manual
By-pass CIP Endcover Assembly the complete system
can be cleaned with the milk collection pump static. This
brings several advantages:
• No Need To Run The Vehicle Engine: The hydraulic
system is not required during cleaning so no engine
fumes are generated in the CIP bay, noise is much
reduced and unnecessary fuel consumption is
eliminated.
• More Effective Cleaning: Tests have shown that
cleaning is more thorough with the Manual By-pass
End Cover fitted.
• Extended Pump Life: During the cleaning cycle the
pump is at greatest risk of running dry. If the cleaning
fluid runs out e.g. during change-over from CIP fluid
to rinse water, the pump impeller can be damaged if
the pump is running. By cleaning the pump static,
impeller life will be extended.
This end cover assembly fits in place of the standard
pump end cover and contains a piston which moves
back under the pressure from the separate CIP cleaning
pump allowing cleaning fluid to by-pass the ends of the
impeller.
CLEANING
Before starting the CIP pump, the center screw (24) of
the manual by-pass assembly is loosened at least 10
turns counter-clockwise. This allows the piston (22) to
travel back under the pressure of the CIP liquid. The
system can then be cleaned using the regime
established by the tanker operator; the pump does not
need to be run or attended to in any way during cleaning.
After cleaning, the center screw is tightened clockwise
ready for normal pumping.
PIPE WORK
The pipe work can be arranged in two ways during cleaning:
1. Parallel piping: the flow from the CIP pump is split at
a tee-piece so part of the flow is taken direct to the
tanker spray balls while the rest flows through the
pump and the metering equipment. See fig 1.
2. Series piping: all the CIP flow is directed through the
pump and metering equipment and then on to spray
balls. See fig 2.
N.B. Do not clean with Phosphoric Acid.

SERVICE INSTRUCTIONS
DISASSEMBLY
1. Remove end cover clamp. Remove end cover and
O-ring.
2. Slide body, complete with impeller and wearplate,
from shaft assembly. Remove impeller from body.
3. Remove mechanical seal from shaft. Use extreme
care not to mar shaft surface. Remove seal seat and
O-ring from recess in wearplate.
4. From the drive end of the bearing housing, pry out
bearing seal by inserting a screwdriver blade
between OD of the seal and housing. Remove
retaining ring. Very carefully withdraw shaft and
bearing assembly.
5. Remove inner bearing seal and retaining ring.
6. To remove bearings from shaft an arbor press is
required. If an arbor press is not available then a
bearing extractor may be used. Supporting inner
race of bearing, apply a steady pressure on shaft
until bearing slides free. Repeat this procedure to
remove second bearing.
ASSEMBLY
1. To replace bearing on shaft. Support bearing on its
inner race and locate shaft onto bearing. Apply a
steady pressure to the shaft until bearing locates
against shoulder on shaft. Repeat for second bearing.
2. Fit retaining ring and bearing seal into impeller end
of bearing housing. Spring on bearing seal to face
outwards.
3. Apply bearing grease around and between bearings,
filling cavity between bearings two thirds full. Smear
grease on shaft where bearing seal locates. Push
shaft and bearing assembly into bearing housing.
4. Replace the two retaining rings and outer bearing
seal, with spring facing outwards, on drive end of
bearing housing.
5. Replace mechanical seal by sliding positioning
washer onto shaft up to locating shoulder, then
smear shaft with light lubricating oil. Push on seal
gently until it engages with washer. Fit O-ring and
seal seat into wearplate.
6. Insert impeller in pump body. Fit O-ring on each end
of the pump body. Fit wearplate to body.
7. Slide wearplate and body assembly over shaft,
positioning wearplate in housing.
8. Fit end cover and end cover clamp. Clamp should
be hand tightened. Do not use wrench or hammer.
9. Changing Pump Rotation (looking at end cover):
Clockwise Rotation: Insert impeller into pump
body with blades bending counterclockwise.
Counter-clockwise Rotation: Insert impeller into
pump body with blades bending clockwise.
