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.
Optimum
tube life
≥ 4 bar
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.
