2. Liquid Supply
Always ensure that liquid storage capacity is adequate to meet the demand.
Ensure the pump chamber is full of liquid before starting the pump. Failure
to do this could result in seal damage. To ensure dry running does not
occur the pumps must be primed as described in the priming section. Do
not run pump dry.
3. Ensure electrical supply is compatible with the details that are stated on the pump
rating plate. (The wrong voltage or frequency can be dangerous and may damage
the pump.)
4. Priming
a) Vertical suction models (flooded suction)
The pump must be primed (filled with liquid) before starting. Turn on liquid
supply, prime and vent the pump by unscrewing the priming plug (Fig. 7)
slowly until all air escapes and liquid emerges. Re-tighten the plug.
b) All models (suction lift installation)
Prime the suction pipework and pump by filling with liquid via the pump discharge
connection, or by filling the suction pipework before attaching to the pump, then
fill the pump.
5. Starting
a) Switch on power to the pump which will now be operational.
b) Carefully check pump and pipework for leaks whilst pump running and stationary
before leaving the installation unattended.
