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 tanks 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.
Pump Mounted Below Liquid Source (Flooded Suction Installation)
Before deciding where to locate the unit, check to ensure the static inlet head (Fig. 7)
meets the minimum requirement of 1 metre and does not exceed the maximum given in
the limits of application section.
The static outlet head (Fig. 7) must also be within the maximum requirement of
8 metres for the K7-2 model and 13 metres for all other models.
