Watson-Marlow 120 IP31 pumps: general information 4
1.6 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.
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.

There are moving parts inside the pumphead.
Before opening the pumphead guard or track,
ensure that the following safety directions are
followed:
Ensure that the pump is isolated from the
mains power.
Ensure that there is no pressure in the pipeline.
If a tube failure has occurred, ensure that any
fluid in the pumphead has been allowed to
drain to a suitable vessel, container or drain.
Ensure that protective clothing and eye protec-
tion are worn if non-flammable hazardous fluids
are pumped.
Primary operator protection from rotating parts
of the pump is provided by the pumphead safeguard. Note that safeguards differ, depending
on the type of pumphead. See the pumphead
section of this manual.
This pump must be used only for its intended
purpose.
The pump must be accessible at all times to facilitate operation and maintenance. Access points must
not be obstructed or blocked. Do not fit any devices

1.8 Good pump
installation practice
1.8.1 General
recommendations
Position
The 120 pump must be mounted in the upright position and not inverted or placed on its rear face.
A correctly engineered installation will promote long
tube life. Site the pump on a flat, horizontal, rigid
surface, free from excessive vibration, to ensure
correct lubrication of the gearbox. Allow a flow of air
around the pump to ensure that heat can be dissipated. Ensure that the temperature around the
pump does not exceed 40C.
It is possible to stack only one other 120 pump on
top of this pump. The case’s third row of feet ensure
ventilation between pumps and allow the top pump
to be set back a little to give clear access to the
lower pump’s keypad. You can place other equipment on the pump’s upper surface as long as the
ambient temperature does not exceed 40C.
Emergency disconnection
The pump's external DC power supply is the disconnecting device, which must be readily identifiable
and easily reached, for isolating the motor drive
from the mains supply. Note: There may be a slight
delay after isolating the pump before the pump
stops.
Watson-Marlow 120 IP31 pumps: general information 8
Valves
Peristaltic pumps are self-priming and self-sealing
against backflow. No valves are required in inlet or
discharge lines. 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.
Pressure advice
In most circumstances,
rotor and tube life are
maximised if the pumphead is run slowly, particularly when pumping at
high pressure. Do not
exceed the pressures
shown here.
1.8.2 Do’s and do not’s
Do not build a pump into a tight location without
adequate airflow around the pump.
Do not strap together the control and and external
DC power supply cables.
Do keep delivery and suction tubes as short and
direct as possible - though ideally not shorter than
1m - 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 (not usually needed) must not restrict the
flow. Any valves in the flow line must be open when
the pump is running.
Do use suction and delivery pipes equal to or larger than the bore of the tube in the pumphead. When
pumping viscous fluids use pipe runs with a bore
several times larger than the pump tube.
Do 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.
Do keep the pumphead track and all moving parts
clean and free from contamination and debris.
Do run at slow speed when pumping viscous fluids
(though see Pressure advice in 1.8.1 General rec-
ommendations). Flooded suction will enhance
pumping performance in all cases, particularly for
materials of a viscous nature.
120 pumps may be wiped with a damp cloth, but
should not be hosed or immersed. The front of the
pump is further protected against light spillages.
When using Marprene or Bioprene continuous
tubing, do re-tension the tube after the first 30 minutes of running.
Tube selection: The chemical compatibility lists
published in Watson-Marlow publications are
guides. If in doubt about the compatibility of a tube
material and the duty fluid, request a WatsonMarlow tube sample card for immersion trials.

1.9 Power supply
The 120 pump is suitable for single-phase mains
electricity supplies only via the double-insulated
(Class II) 90-264VAC-to-24VDC mains adaptor. Use
only the approved 24VDC Meanwell type GE24I24P1JK DC adaptor or the Powersolve ESA24-24 DC
adaptor supplied with the pump.
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
supplies such as 3-phase contactors and inductive
heaters without special attention being paid to
unacceptable mains-borne noise.
To prepare your power supply
Select the mains input adapter appropriate to
your region—UK, US, Australia or Europe—and
slide it into position on the rear of the unit.
Ensure it clicks into place.
Stop/start power cycles: Do not power up/power
down for more than 100 starts per hour. A minimum interval of 3 seconds is required between power
cycles.
We recommend using commercially available supply
voltage surge suppression
where there is excessive
electrical noise.
