PIPE/HOSE CONNECTIONS
The pump inlet and discharge ports
½
are both 1
" BSP (38 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 1
• 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.
