2Pressure side
These on-hand instructions contain information
for installation, operation and maintenance of
ELRO peristaltic pumps.
You should therefore thoroughly read these
instructions before use and always follow the
information contained therein.
All personnel involved in activities on pump or
equipment associated with the pump must have
read this manual, especially the chapter ”Safety”
before starting work.
This also applies to persons who work on the
pump only occasionally, e.g. for maintenance
and cleaning work.
Each pump is subjected to stringent inspections
and function tests before leaving the factory.
You should always bear in mind that the
function, long lifetime and optimal operational
reliability of the pump mainly depend on
• correct installation
• correct commissioning and
• proper and scheduled maintenance.
Enquiries concerning service, spare parts or
repairs should be addressed to the
manufacturer or an authorized dealer.
Always provide the following information:
• Series
• Pump size
• Serial number of pump
This information is stamped on the identification
plate on top of the pump.
When returning pumps or pump parts to the
manufacturer or an authorized dealer for repair
or overhaul, the delivery must be accompanied
by a certificate stating that the pump is free of
product or other aggressive or hazardous
substances.

To avoid slipping of the loop, the
rope must be crossed over on the
hook.
If the pump is not installed immediately, it
should be packed up again and stored in a
suitable place. For this the following points must
be observed:
•All pump ports must be closed with
appropriate plugs.
•Pumps with corrosion protection must be
packed up again and stored in the original
packaging material.
•The pump is to be stored in a clean, dry and
vibration insulated place. The pump should
be covered with a material that provides
sufficient protection against dampness, dust,
dirt and other contaminants.
1.1 Warranty
The correct function of each ELRO peristaltic
pump is checked in the factory before
shipment. The manufacturer or authorized
dealer assumes warranty for the product as
specified in the effective terms of sales and
delivery. Faults resulting from the non-
compliance with the afore mentioned
regulations and notes can only be rectified at
the cost of the customer.
1.2 Transport, storage
In order to avoid any problems you should
• check the delivered goods against the
delivery note for completeness and
correctness,
• check pumps with drive units for availability of
the instructions manual for the drive upon arri-
val of the goods.
Be careful when unpacking the pump and
proceed as follows:
• Examine the packaging for transport damage.
• Take the pump carefully out of the packaging.
• Examine the pump for any visible damage.
• Remove all plugs from the pump ports.
Consider the indicated weight
before attempting to lift the pump.
Use only lifting gear of appropriate
capacity.
Do not step or stand under
suspended loads.
Pumps without drive: The hoisting rope must
be slung around pump body and drive shaft.
Pumps with drive: The hoisting rope must be
slung around pump body and motor.
In order to avoid slipping of the sling,the rope
must be crossed over at the hook.

1.3 Function
1Torsion resistant cast aluminium housing
2Rotor with sliding pieces
3Hose with vacuum bore
4Connections (standard)
5Vacuum channel
6Vacuum gauge to monitor the vacuum in the pump
Fig. 2
This additionally aids the restoring force of the
hose to its original full cross section.
The IP series of peristaltic pumps work on the
basis of a patented vacuum principle.
As the rotor turns, air is pumped through an
additional channel in the hose (see cross
section Fig. 3) out of the upper area of the
pump housing.
This generates a vacuum inside the sealed
aluminium housing.
Fig. 3

11
Peristaltic Pumps Series IP 100-800
With each rotation of the rotor the two sliding
pieces discharge product towards the pressure
side, while the same quantity is drawn in by the
vacuum on the suction side (Fig. 7).
Fig. 5
Fig. 7
Fig. 4
Fig. 6
The rotor rotates inside the lubricant filled pump
housing and compresses the hose with its outer
rotor ends. This process hermetically separates
the suction from the pressure side (Fig. 4).
The volume (Fig. 5) between both rotor ends is
exactly half the displacement per revolution.
The rotation of the rotor displaces the product
inside the hose towards the outlet port on the
pressure side. This generates a vacuum in the
suction side each time the hose opens, which
ensures constant drawing in of product. This
takes place even when there is no product in
the pump, making the pump self-priming.

not be made ineffective.
Rotating or moving parts must be reliably
stopped before starting work. It must be
assured that these parts will not start to move
while work is in progress.
Do not touch rotating parts and always keep a
safe distance to avoid clothing or hair being
caught.
Always wear protective clothing suitable for the
job and the related dangers.
Depending on the type of work to be performed
sufficient protection may be provided by e.g.
wearing the following protective clothing:
Protective goggles, ear defenders, working
boots, safety gloves, etc.
Protective clothes should be of tight fit.
If your face could come in contact with
chemicals, metal splinters or dust during work,
you should wear a full face protection with
safety goggles.
Always wear safety boots where there is a risk
of heavy objects tipping over, slipping or coming
loose for any other reason, thereby causing
danger for your feet.
2.7.1 Health and safety information on
electric equipment
Depending on the version, the pumps may be
equipped with electric accessories (controls,
motor drives).
Severe damage to health and property can be
caused by:
•unauthorized removal of covers
•unprofessional use of pump
•inadequate maintenance
Before starting installation work on electrical
equipment this equipment must be reliably de-
energized.
Cover non-insulated live power lines and plug
connections against unintended contact.
Electric components stored and not used for a
longer period of time should be carefully
inspected before use, to ensure that the
insulation is still intact.
Wet electric assemblies or components parts,
which would be perfectly de-energized in dry
condition, may still be live.
Before touching damp or wetted electric
components check by measuring whether parts
that could be touched are still live.
When working on high voltage assemblies after
voltage has been switched off, connect the
supply cable to ground and short components,
e.g. capacitors, via a discharge combination.
Do not attempt to insert any objects through the
openings on pump or attached equipment. This
may cause short circuit and electric shocks with
danger to life.
2.7.2 Health and safety information for work
on pressure lines
Always relieve the pressure before starting
work on pressure lines.
•Close shut-off valves
•Vent pressure lines
Be careful when checking for leaks
on pressurized lines. Fluids or air
escaping under pressure can
penetrate clothes and skin.
Be careful when loosening or
changing pressure lines; lines
mixed up by mistake may reverse
the function.
Always relieve the pressure from hydraulic or
pneumatic systems and move mobile parts to a

safe home or parking position before starting
work.
Take care when handling hazardous (caustic,
harmful) fluids.
•Always wear your personal protective outfit
(e.g. gloves, goggles, tight fitting clothes).
•In case of skin contact, inhalation of harmful
vapours or eye injury you should
immediately contact a physician.
2.7.3 Regulations and instructions on
lubrication
(Only of relevance if the pump is equipped with
a lubrication system)
Lubrication work must only be carried out by
authorized personnel. The professional
execution of this work must be examined and
approved by a highly skilled ”Inspector”.
Unauthorized persons must not be permitted to
work on machines or units or in their vicinity.
Lubricants and oils must not come in contact
with open flames or glowing parts.
When working on assemblies and components
(e.g. motor, gearbox) you must also consider
the specific instructions and lubrication
instructions for these assemblies and
components.
The complete system must generally be
switched off and secured against unintended
and unauthorized restarting before starting
lubrication work.
(Exception: Lubrication work that can only be
performed when the system is running).
As a measure to avoid injury all lubrication work
should only be carried out using permitted and
appropriate tools and working aids.
Rotating or mobile parts must be shut down and
reliably secured against restarting before
starting work.
Do not touch rotating parts and always keep a
safe distance to avoid clothing or hair being
caught.
Strict cleanliness is of utmost importance during
initial filling and when topping up or changing
lubricant so that no foreign matter will enter
through the lubrication point.
Overflowing and spilling of oil must be avoided.
Wipe off excessive and emerging grease.
Avoid skin contact with oils and grease – wear
protective clothes.
With certain lubricants, e.g. flammable hydraulic
fluids, the special safety instructions for these
substances must be observed. (See notes on
packaging and instructions of manufacturer).
2.8 Noise
In a room with several pumps the noise level
may be very high. Depending on the sound
pressure level the following measures should be
applied:
below 70 dB(A): No special measures
required
above 70 dB(A): Persons who are
permanently in the room must
wear hearing protection.
above 85 dB(A): Room with dangerous
noise level!

3. Installation Instructions
3.1 Points to be observed before
installation
Installation work must only be performed by
skilled personnel by following the safety
regulations (see chapter 2).
Fig. 8
1. The pump is delivered ready for operation.
Before commissioning make sure that pump
and drive unit are correctly assembled.
The standard pump is delivered with suction
port at top / pressure port at bottom –
connections on left hand side (Fig. 8).
Pipe lines must be routed in a way that the
weight of the pipes does not rest on the
pump.
2. If the pump is to be installed in a rigid pipe
system it is recommended to use flexible
pipe sections (e.g. expansion joints,
pressure resistant hoses) on pressure and
suction side.
3. In order to avoid damage to the pump new
installations should generally be checked for
any debris (welding beads, pieces of wire,
etc.) in tank and pipeline system and piping
flushed clean.
4. Check the pump arrangement to ensure that
suction lift and discharge head are not
exceeded. Check also motor speed and
power in HP/kW.
The pump performance curves can be used
to check the flow rate at a given speed.
3.2 Installation and connection
The pump unit must be installed and fastened
on a level base of suffient load bearing capacity
for the weight of the pump.
See foundation plan Fig. 9.

Peristaltic Pumps Series IP 100-800
Since the pump is a positive displacement
pump it must be assured that the discharge
piping has no shut-off elements, pipe tapers or
components that could cause clogging of the
piping.
An On/Off-switch with locking against switching
on (e.g. lockable switch, switch with detachable
switching lever) should be installed near the
pump.
This is a precaution to avoid accidents, e.g.
when inspecting the inside of the pump.
To avoid overloading of the pump we
recommend the installation of a motor
protection switch.
Electrical installations and
connections must only be made by
a qualified electrician.
In order to ease the necessary service work it is
recommended to install approx. 1 - 1,5 m,
3 - 4.5 ft, removable lines (hoses or pipes)
between pump ports and pipe system (Fig. 10).
This provides sufficient working space for
changing the pumping hose.
The pump cover must always be easily
accessible!
Peristaltic pumps are variable displacement
pumps, which produce a pulsating product flow.
In order to prevent these pressure shocks from
being transferred into the piping system, both
pressure and suction sides should be fitted with
expansion joints (Fig. 10). As an additional
measure to minimize pulsation, the pressure
pipe can be fitted with an active pulsation
damper. These must be adjusted to the
respective working range. For optimal results
refer to the installation instructions provided by
the respective manufacturers of expansion
joints and pulsation dampers.

The use of shut-off valves in the pressure line
requires the installation of an overflow valve with
return line (or by-pass or an over-pressure
switch), in order to avoid damage to the peristaltic
pump caused by operating errors (Fig. 11).
Should this not be possible, the pump must be
switched off before closing the valve.
Peristaltic pumps must never be
operated against closed shut-off
elements!

4. Operating Instructions
4.1 Points to be observed before
commissioning
Please check:
•whether the pump is correctly installed and
connected.
•whether the direction of pump rotation is
correct.
The direction of rotation is anti-clockwise,
when viewed from the pump cover (if not
specified differently by the customer).
An arrow on the pump marks the direction of
rotation
•that a pump without explosion protected
drive is under no circumstances used in an
explosive environment.
•whether the pumping hose inside the pump
is suitable for the product to be pumped.
•whether suction and pressure lines are
correctly connected.
•whether switches and power connections for
the drive are correctly connected.
•whether the pump is correctly earthed in
order to avoid electro-static charging.
•whether the ventilation breathen on the
gearbox is free and open.
•For the electric motor an overcurrent relay
must be installed. For this the wiring diagram
in the electric junction box must be
observed.
•On motors with thermal circuit breakers all
cables and terminals are arranged inside the
junction box of the motor. These must be
connected so that the motor is stopped when
the switch is triggered.
4.2 4.2 Commissioning
The drive unit is to be started up in accordance
with the respective operating instructions.
Check the lubrication of the drive unit.
Geared motor and regulating gears are filled for
grease lubrication. In case of oil lubrication the
oil in the gear housing must be checked and, if
necessary, filled up before commissioning.
Make sure that all safety devices are fastened
and fully functional.
The peristaltic pump must not be
operated against closed shut-off
valves.
The pump housing must always be
filled with a sufficient amount of
lubricating fluid.
Switching on
The pump starts when the main switch for the
drive is switched on.
Switching off
Switch the main switch for the drive unit off
again.
The inner diameters of suction and pressure
lines should be at least the same size as the
pumping hose. The ideal radius for elbows is
> 2 – 3 times the pipe diameter. When pumping
highly viscous fluids (> 10.000 cPs) the
diameter of the suction line should be as big as
possible, but its lengths as short as possible.
For highly viscous fluids (>10.000 cPs) the
diameter of the suction line should be one size
bigger than the connection socket on the pump.
Please note that the suction line should be as
short as possible.

installation and cleaning work must only be
performed by authorized and trained personnel.
1. Switch off the electric power supply and
secure against unintended restarting.
2. Close shut-off valves on suction and pressure
side.
3. Relieve the pressure in suction and pressure
lines.
Fluids escaping under pressure can
cause severe injury.
Take care when loosening pressure
fittings; wear protective clothing.
Be extremely careful when handling
hazardous fluids.
You should immediately consult a
doctor if you had contact with such
substances.
4. Loosen suction and pressure fittings carefully.
The system may still be under pressure or
tension.
5. Disconnect suction and pressure lines from
the pump and disassemble the rinsing line (if
present).
6. If worn parts are detected when inspecting the
pump, the respective parts must be replaced.
5. Maintenance
Always observe the safety
regulations in chapter 2 when
performing maintenance work and
conversions!
Check all lines and fittings regularly for leaks
and externally visible damage!
Eliminate any faults immediately!
Peristaltic pumps of series IP require only little
maintenance. Ball bearings and radial seals in
the pump neck are lifetime lubricated by the
silicone oil or glycerine filling.
The drive must be serviced according to the
instructions of the respective manufacturer.
The pumping hose is the only wear item on the
pump.
Pumps with electric drive must be
switched off and disconnected
from the electric power supply
before starting maintenance work!
If the pump is used for aggressive,
caustic or toxic media, the pump
must be flushed with a neutralizing
agent before opening the pump
housing.
5.1 Cleaning
General notes:
Always wear protective clothing
when working with solvents or
cleansing agents.
Housing, cooling fins, openings and covers on
equipment components are very often not just
protections, but have additional functions such
as cooling, insulation, noise reduction, splash
protection, etc.

5. Finally flush with cold water.
5.1.2 Selection of pumping hoses
Peristaltic pumps may be fitted with hoses of
various materials, depending on the application.
The following materials are available:
Colour end code
Natural rubber (NR) yellow
Natural rubber for food blue
Hypalon (CSM) black
Nitrile rubber (NBR) red
Butyl rubber (IIR) green
EPDM (EPDM) white
Before installing a new hose you should make
sure that the hose material suits the intended
application (see compatibility list). If the hose
inside the pump has not been damaged by nor-
mal mechanical wear, but by chemical attack,
you should use a hose of different material.
Some of these functions can be impaired or
may become totally ineffective by excessive
deposits of dirt.
Some advice on how to remove dirt.
• Dried on dirt can be removed by scratching,
scraping or brushing
• Minor dirt deposits, such as layers of dust and
fine deposits can be wiped off, cleaned off
with a vacuum cleaner, removed with a
brush or broom
5.1.1 Cleaning pumps for food applications
(CIP = Clean in place)
The pumps can be cleaned manually after
disassembly or in place (CIP).
Consult the pump supplier for special
application related cleaning procedures.
Do not touch pump or pipes. Dan-
ger or burning!
Always wear your personal
protective outfit when handling
chemicals.
Always flush the system
thoroughly after.
Always observe the applicable
regulations when storing or
dispensing chemicals.
Possible CIP-cleaning procedure for pumping
hoses made of natural rubber.
1. For cleaning the pumping hose the pump
must be flushed with cold water.
2. For product susceptible for sticking or
incrustation we recommend to have cleaning
balls available.
3. Flush the pump with hot water (max. 90°C /
195°F) for max. 20 minutes (when using a
frequency converter run at slow speed).
4. Clean with an approx. 2.5% alkaline soda
solution.
Caution!
