1 Declaration of conformity

This declaration was issued for Watson-Marlow 825 and 840 pumps on
August 1, 2006. When this pump unit is used as a stand-alone pump it
complies with: Machinery Directive 2006/42/EC, Low Voltage Directive
2004/108/EC. See 8 Pump specifications.

2 Declaration of incorporation

When this pump unit is to be installed into a machine or is to be assembled with
other machines for installations, it must not be put into service until the relevant

Conditions of and specific exceptions to the above warranty are:

 Consumable items such as rollers and tubing are excluded.
 Products must be returned by pre-arrangement, carriage paid, to Watson-

4 Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxoc
chemicals or any other substance hazardous to health must be decontaminated
before it is returned to Watson-Marlow or its distributors.

A certificate included at the rear of these operating instructions, or a signed state­ment, must be attached to the outside of the shipping carton.

This certificate is required even if the pump is unused. If the pump has been used,
the fluids that have been in contact with the pump and the cleaning procedure must
be specified, along with a statement that the equipment has been decontaminated.

5 Safety

In the interests of safety, these pumpheads and the products selected should only
be used by competent, suitably trained personnel after they have read and under­stood this manual, and considered any hazard involved. In the UK this person should
be familiar with the Health and Safety at Work Act 1974.

Any person who is involved in the installation or maintenance of the equipment
should be fully competent to carry out the work.

There are dangerous voltages (at mains potential)
inside the terminal box. If access is required, isolate

the pump from the mains before removing the terminal
box cover. Do not olace any part of the body inside the pump­head while the pump is running.

7 Recommended operating
procedures

Do keep delivery and suction tubes as short and direct as possible using a minimum

of swept bends

Do use suction and delivery pipes equal to or larger than the bore of the tube in the
pumphead. When pumping viscous fluids, the losses caused by increased friction can
be overcome by using pipe runs with a cross sectional area several times greater
than the pumping element.

Do keep the pumphead track and all moving parts clean and free from contamina­tion and debris.

The self-priming nature of peristaltic pumps means valves are not required. Any
valves fitted must cause no restriction to flow in the pumping circuit.

If the rotor is run in an anticlockwise direction with both rocker mechanisms
unlocked no tube occlusion will occur. In this case the rocker mechanisms will snap
back from their disengaged position when losing contact with the tubing. No dam­age to the pumphead action will be caused by this, however it is not advisable to
allow this action to continue for a prolonged procedure.

8 Installation

Site the pump on a flat horizontal surface allowing a free flow of air around the
pump. Ensure there is 1m of straight tubing before the pumphead inlet and dis­charge ports.

When requested, motors fitted to Watson-Marlow pumps incorporate a thermal pro­tection switch which may be used to provide indication of an over-temperature con­dition. Aside from this, a current overload relay should also be fitted to a contact
breaker. Connect the motor in accordance with the wiring diagram which will be
found in the motor terrminal box.

When a thermal protection switch is fitted in the motor, the leads will be found in
the motor terminal box. They should be connected to stop the pump if the switch
operates. The switch will open circuit at an over temperature condition. See picture
for the simplest connection.

All pumps may be fitted with a door indicator switch. This switch is rated 240V 0.5A
AC maximum power load 50W. This switch is not intended as a primary safety
device. Under normal operation the pumphead door is kept closed and this meets all
statutory requirements as a tool lockable fixed guard.

Do not connect the door switch a back up or any other switch gear with the termi­nal box of an explosion proof motor unless the switch has a suitable Exd rating for
the zone area in which it is to be mounted.

11 Roller adjustment

 Loosen the roller locking nut (1) and undo rock-

er locking nuts (2)

 Undo the roller spindle locking nuts
 Rotate roller for occlusion adjustment (below).

Setting 2 represents the factory default setting.

12 CIP

When using a clockwise pumping direction and unlocked rockers no adjustment is
required. If rockers are locked for bi-directional pumping unlock one rocker mecha­nism. Rotate rotor anticlockwise until no tube occlusion occurs. The free flow of
cleaning agents through the tubing is now possible.

Ensure that no part of the body inside the pumphead
while the pump is running.

Watson-Marlow 825 and 840 User Manual 9

13 SIP

Observe a 1m safety area to avoid possible scalding if a tube burst occurs. Monitor
the process continuously .

If a tube burst occurs shut down the process, do not touch the pumphead until a 10
minute cooling period has been observed. Ensure a 15 minute acclimatisation peri­od is observed before running the pump following SIP.

Maximum permissible SIP process temperature is 135 C.

14 High pressure operation

 Ensure rocker mechanisms are locked to avoid premature wear.
 Observe a 1m safety area to avoid contact with high pressure jets in the case of

a tube burst.

 Please note that only tubing elements and not continuous lengths of tubing can be

used for higher pressure operation.

 No quick connectors are to be used with element tubing during high pressure

operation.

15 Tubing

No length of tubing which has previously been used as a pumping element should
be used in the transfer section due to the fact that it may be in a weakened condi­tion.
