5 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.

9 Good pump installation practice
9.1 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.
The pump may be set up so that the direction of rotor rotation is clockwise or counter-clockwise, whichever
is convenient.
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.
Peristaltic pumps are s elf- 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.

9.2 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 cable 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.
lIf your pump is a PROFIBUS variant do ensure that it is installed in accordance with PROFIBUS
installation guidelines.
lDo not allow tight bends in any PROFIBUS signal cable.
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.

11 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 'dirty' electrical mains
devices, such as 3- phase contactors and inductive heaters without special attention being paid to
unacceptable mains-borne noise.
Set the voltage selector to 115V for 100-120V 50/60Hz supplies or
230V for 200-240V 50/60Hz 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.
