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 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.
