1. System Flushing
Some pumps incorporate plastic components that must not come into
contact with solder flux, acid-based descalents or aggressive cleaning
agents. The pipework system should be flushed out prior to the pump
being connected, to ensure any contaminants/chemical residues and
foreign bodies are removed from elsewhere in the system.
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) Flooded suction installation.
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. 19)
slowly until all air escapes and liquid emerges. Re-tighten plug.
b) 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.
c) X201 only (suction lift installation)
This pump is capable of priming the suction hose with liquid on installation.
Ensure both suction and delivery hose connections are air tight. Remove the
yellow priming plug located on the top of the pump housing. Fill the pump body
with liquid slowly allowing the air to escape.
Fully submerge suction hose in liquid source. When all is satisfactory the
electrical supply can be switched on, (whilst the pump is priming, the delivery
must be open). If nothing happens after 5 minutes, switch the pump off, re-prime
the pump again.
Note: The amount of time taken for priming and the number of times priming is
required will vary dependant on height of suction lift.
The suction pipe can also be fitted with a footvalve and strainer which will ensure
the pump and pipework remains primed at all times. The suction hose should not
exceed 32 mm dia bore.
