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.
