Fundamental work with regard to lifting, transportation, installation,
starting-up, maintenance and repair should be performed by qualified
personnel only. The unit must be isolated from mains power while
work is being carried out. The motor mus t be secured against
accidental start-up.

There is a user-replaceable type fuse in the fuse holder above the
power input connector at the back of the pump . In some countries, the
mains power plug contains an additional replaceable fuse.

There are no user-serviceable fuses or parts inside this pump.

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 to the drive
unit other than those tested and approved by Watson-Marlow Ltd. Doing so could
lead to injury to persons or damage to property for which no liability can be
accepted.

The pump's main plug is the disconnecting device (for isolating the motor drive
from the mains supply in an emergency). Do not position the pump so that it is
difficult to disconnect the mains plug.

If hazardous fluids are to be pumped, safety procedures specific to
the particular fluid and application must be put in place to protect
against injury to persons.

This product does not comply with the ATEX directive and must not be
used in explosive atmospheres.

The PF7 contains a non- replaceable Manganese Dioxide Lithium Battery (Li/MnO2),
IEC CR2032, with a typical capacity of 225mAh, containing 0.07g of Lithium.

Primary operator protection from rotating parts of this pump is
provided by isolating the pump from mains power before opening the
pump head tube bridge. The pump also provides a tube bridge open
indicator. If the tube bridge is opened, the tube bridge open screen is
displayed.

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.

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.

7.1 Tube selection

Tubes must be selected according to the application and volume to be filled. Use the
table shown below for choice of tubes according to minimum volume to be filled.

In order to obtain stable and good results, the choice of tubing can be made
according to the following guideline:

Volume (ml) Filling Nozzle

(mm i.d.)

Tubing

(mm i.d.)

Y-Connector

(mm i.d.)

<0.50 0.6 0.5 1.2

12.0 - 22.0 4.5 4.8 4.8

22.0 - 35.0 6.0 6.0 4.8

> 35.0 8.0* 8.0 7.5

* use non-return valve

7.2 Placing the product container

In order to get an optimal filling; i.e. best accuracy, long periods between each
calibration and the best capacity, the product container should be placed at the
same level as pump head or preferably above the pump head level. The length
between container, pump head and filling nozzle must be as short as possible.

Placing the container higher than pump head level provides positive product
support and may reduce the calibration interval. It is also recommended to place
the container as close as possible to the pump on suction side.

Ensure there are no tight bends or obstructions which could reduce the fluid flow in
the tube line.

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 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.

Peristaltic pumps are self-priming and self-sealing against backflow. No valves are
required in inlet or discharge line, except those specified as below.

8.2 Dos and don'ts

l Do not build a pump into a tight location without adequate airflow around the

pump.

l Do 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.

l Do 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.

l Do 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.

l 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.

l Do run at slow speed when pumping viscous fluids. Flooded suction will enhance

pumping performance, particularly for materials of a viscous nature.

l Do recalibrate after changing tubing, fluid or any connecting pipework. It is also

recommended that the pump is recalibrated periodically to maintain accuracy.

l Do not pump any chemical not compatible with the tubing or pumphead.

l Do not run the pump with no tube or element fitted to the pumphead.

l Do not strap the control and mains cable together.

9 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 mains­borne noise. Make suitable connection to an earthed single-phase mains electricity
supply.

The PF7 uses a standard IEC socket and a country specific cord set. Ensure that all
power supply cables are adequately rated for the equipment.

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.

10 Control wiring

There are two off, M12 8-pin connectors on the rear of the PF7 unit; these contain
pins that allow both inputs and outputs. Both connectors have the same pin
configuration. The use of each pin is shown in the tables below, along with the pin
function and the signal response.

Never apply mains power to the M12 connectors. Apply the correct
signals to the pins shown. Limit signals to the maximum values
shown. Do not apply voltage across other pins. Permanent damage,
not covered by warranty, may result.

12 Troubleshooting

If the pump display remains blank when the pump is switched on, make
the following checks:

• Check that the mains power is available to the pump.

• Check the fuse in the wall plug if one is present.

• Check the position of the voltage selector switch.

• Check the mains power switch at the rear of the pump.

• Check the fuse holder in the centre of the switch plate at the rear of the pump.

If the pump runs but there is little or no flow, make the following
checks:

• Check that fluid is supplied to the pump.

• Check for any kinks or blockages in the lines.

• Check that any valves in the line are open.

• Check that the tube and rotor are in the pumphead.

• Check that a tube is not split or burst.

• Check that the correct wall-thickness tube is being used.

• Check the direction of rotation.

• Check that the rotor is not slipping on the drive shaft.
