PIPE/HOSE CONNECTIONS
The pump inlet and discharge ports
are both 2" BSP (51 mm) female
threads and accept the adaptors
supplied.
Hoses with the same diameter should
be used and secured to the adaptor
with a suitable hose clip.
Ensure all connections are air tight
when under pressure but not so tight
as to crack the plastic inlet/outlet adaptors.
ADDITIONAL CONSIDERATIONS
• Strain caused by vibration can be reduced by connecting a short
flexible hose between any rigid pipework and the pump.
• We recommend that you always use pipes/hoses with a minimum
diameter of 2" (51 mm).
• Any restriction in the pipeline will greatly reduce the flow.
• Ensure that the hoses and pipes are supported along their entire
length. They will be considerably heavier when filled with water.
• We recommend that you install isolation valves either side of the
pump in order to isolate the pump during maintenance/removal.
• A gate valve may be installed in-line on the delivery side of the
pump which can be adjusted as required to regulate the flow of
water and can assist in priming the pump.
• If there is any chance of freezing, protect the pump and pipework
with suitable lagging. The formation of ice may cause serious
damage.
