4 Peristaltic pumps - an overview
Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to clog or corrode.
The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or
the fluid contaminating the pump. Peristaltic pumps can operate dry without risk.
How they work
A compressible tube is squeezed between a roller and a track on an arc of a circle, creating a seal at
the point of contact. As the roller advances along the tube, the seal also advances. After the roller has
passed, the tube returns to its original shape, creating a partial vacuum which is filled by fluid drawn
from the inlet port.
Before the roller reaches the end of the track, a second roller compresses the tube at the start of the
track, isolating a packet of fluid between the compression points. As the first roller leaves the track,
the second continues to advance, expelling the packet of fluid through the pump’s discharge port. At
the same time, a new partial vacuum is created behind the second roller into which more fluid is
drawn from the inlet port.
Backflow and siphoning do not occur, and the pump effectively seals the tube when it is inactive. No
valves are needed.
The principle may be demonstrated by squeezing a soft tube between thumb and finger and sliding it
along: fluid is expelled from one end of the tube while more is drawn in at the other.
Animal digestive tracts function in a similar way.
Suitable applications
Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive
fluids, and those containing suspended solids. They are especially useful for pumping operations
where hygiene is important.
Peristaltic pumps operate on the positive displacement principle. They are particularly suitable for
metering, dosing and dispensing applications. Pumps are easy to install, simple to operate and
inexpensive to maintain.

8 Good pump installation practice
8.1 General recommendations
It is recommended that the pump is sited on a flat, horizontal, rigid surface, free from excessive
vibration, to ensure the correct lubrication of the gearbox and correct pumphead operation. Allow a
free flow of air around the pump to ensure that heat can be dissipated. Ensure that the ambient
temperature around the pump does not exceed the recommended maximum operating temperature.
The STOP key on pumps supplied with a keypad will always stop the pump. However, it is
recommended that a suitable local emergency stop device is fitted into the mains supply to the pump.
Do not stack the pumps more than the recommended maximum number. When the pumps are
stacked, ensure that the ambient temperature around all the pumps in the stack does not exceed the
recommended maximum operating temperature.
Figure 2 - Pump stacking
The pump may be set up so that the direction of rotor rotation is clockwise or counter-clockwise,
whichever is required.
Please note, however, that for some pumpheads the tube life will be greater if the rotor rotates
clockwise; and that performance against pressure will be maximised if the rotor rotates counter-
clockwise. To achieve pressure in some pumpheads the pump must rotate counter-clockwise.
Optimum
tube life

pressure
Figure 3 - Rotor direction
Peristaltic pumps are self-priming and self-sealing against backflow. No valves are required in inlet or
discharge line, except those specified as below.
Users must fit a non-return valve between the pump and the discharge
pipework to avoid the sudden release of pressurised fluid in the event of a
pumphead or tube failure. This shall be fitted immediately after the discharge
of the pump.
Valves in the process flow must be opened before the pump operates. Users are advised to fit a
pressure relief device between the pump and any valve on the discharge side of the pump to protect
against damage caused by accidental operation with the discharge valve closed.
14 m-630pn-en-09 02-02-22

8.2 Dos and don'ts
lDo not build a pump into a tight location without adequate airflow around the pump.
lDo keep delivery and suction tubes as short and direct as possible - though ideally not
shorter than one metre - and follow the straightest route. Use bends of large radius: at least
four times the tubing diameter. Ensure that connecting pipework and fittings are suitably
rated to handle the predicted pipeline pressure. Avoid pipe reducers and lengths of smaller
bore tubing than the pumphead section, particularly in pipelines on the suction side. Any
valves in the pipeline must not restrict the flow. Any valves in the flow line must be open
when the pump is running.
lDo ensure that on longer tube runs at least one metre of smooth bore, flexible tubing is
connected to the inlet and discharge port of the pumphead to help to minimise impulse
losses and pulsation in the pipeline. This is especially important with viscous fluids and when
connecting to rigid pipework.
lDo use suction and delivery pipes equal to or larger than the tubing diameter bore. When
pumping viscous fluids use pipe runs with a bore several times larger than the pump tube.
lDo site the pump at or just below the level of the fluid to be pumped if possible. This will
ensure flooded suction and maximum pumping efficiency.
lDo run at slow speed when pumping viscous fluids. Flooded suction will enhance pumping
performance, particularly for materials of a viscous nature.
lDo recalibrate after changing tubing, fluid or any connecting pipework. It is also
recommended that the pump is recalibrated periodically to maintain accuracy.
lDo not pump any chemical not compatible with the tube or pumphead.
lDo not run the pump with no tube or element fitted to the pumphead.
lDo not strap the control and mains cables together.
lDo ensure if your product has an N module, that the module is fitted with the seals intact
and properly located. Ensure that the holes for the cable glands are properly sealed to
maintain the IP/NEMA rating.
Tube selection: The chemical compatibility guide published on the Watson Marlow website is for
guidance. If in any doubt about the compatibility of a tube material and the duty fluid, request a
Watson-Marlow tube sample card for immersion trials.
When using Marprene or Bioprene continuous tubing, do re- tension the tube after the first 30
minutes of running.

10 Connecting to a power supply
A well regulated electrical mains supply is required along with cable connections conforming to the
best practice of noise immunity. It is not recommended to site these drives alongside electrical
devices that may generate mains-borne noise, for example 3-phase contactors and inductive heaters.
Set the voltage selector to 115V for 100-120V 50/60Hz supplies or 230V for
200-240V 50/60Hz supplies. Always check the voltage selector switch before
connecting to the mains supply or the pump will be damaged.
Make suitable connection to an earthed single-phase mains electricity
supply.
If the pump type is one with an N Module, the voltage selector is not visible while the
module is in place. It is mounted in the switch plate at the rear of the pump, protected
from water by the N Module. The module must be removed to allow access to the switch
plate. Do not switch the pump on unless you have checked that it is set to suit your power
supply by removing the module and inspecting the switch and then refitting the module.
1. 2.
3. 4.
Figure 9 - Voltage selector
We recommend using a commercially available supply voltage surge and/or
noise suppression where there is excessive electrical noise.
Ensure that all power supply cables are adequately rated for the equipment.
Only use with supplied power cable.
The pump must be positioned so that the disconnection device is easily
accessible when the equipment is in use. The pump's power input plug is the
