temperature of no more than 40 C.
Ÿ
Locate on a solid flat surface ensuring
the shaft is in a horizontal position.
Ÿ
Ensure that the diameter of the suction
pipe is at least the size of the pump
suction inlet. If the suction depth exceeds
4 meters then a one size larger diameter
pipe should be used, though for
maximum pump performance suction height should be minimised.
Ÿ
If there is negative suction (i.e. the pump is above the suction water level)
the suction pipe must be slightly angled upwards towards the pump inlet to
avoid the formation of air locks. It must also be immersed in water by at
least 0.5m to avoid the formation of vortexes and a good quality foot valve
must be fitted.
Ÿ
Ensure that all suction pipe connections are completely airtight or else
the pump will not operate. The diameter of the delivery pipe must be
chosen to suit the flow rate and pressure required at the delivery point
though must not be smaller than the pump outlet size. It is also advisable
to fit a non-return valve and isolating valve on the delivery outlet. This
measure is essential if the delivery pressure exceeds 20 meters.
