SITING OF THE PUMP/PIPEWORK
WARNINGS:
 Pump Location
If possible site the pump in a location where in the unlikely event of a
liquid leak, any spillage is contained or routed to avoid electrics or
areas sensitive to liquid damage.
 Care should be taken to protect the pump from frost and freezing.

Ensure pipework to and from pump is independently supported to
prevent stress on the pump inlet and outlet branches.

Do not fit a non-return valve, or devices which contain non-return
valves, in the suction (inlet) pipework to the pump. Exceptions can
be made in the case of suction lift installations when a footvalve is
required.

When a footvalve is required on installations that incorporate
automatic pump control, it is recommended that a suitable pressure
relief valve be fitted in the discharge (outlet) pipework from the pump.
 Do not run against a closed valve for periods longer than 5 minutes.

Do not allow plastic pump parts to come into contact with oil or
cellulose based paints, paint thinners or strippers, acid based
descalents or aggressive cleaning agents.
 Do not introduce solder flux to pumps or pump parts manufactured
from plastic. All solder joints should be completed and flux residues
removed prior to pump connection.

The motor casing can become very hot under normal operating
conditions. Care should be taken to ensure it cannot be touched
during operation.
 Always install isolating valves to both suction and delivery pipework.
Site the pump in a horizontal, dry, frost-free position where it cannot be sprayed with
water and as close to the liquid source as possible.
The pump enclosure must be ventilated and there should be a minimum clearance of
80 mm between the pump and housing on all sides.
To prevent loss of pressure through pipework, use pipe size to match pump whenever
possible, minimising 90° bends.
It must be ensured that storage capacity of the liquid supply is adequate for the flow
rates required by the pump.
The pipework feeds to the storage tank should be of adequate size to ensure
replenishment rate of tank is sufficient to meet the needs of the pump.
Isolating valves should be fitted in suction and delivery pipework to enable easy isolation
and access to the pump.
When the pump is to be installed in areas where there is a risk of debris or scale build up
within the system, it is recommended that the inlet pipework is fitted with an inline strainer.
