Pump Mounted Above Liquid Source (Suction Lift Installation):
Fig 3.
Diagram showing typical pressure control installation with suction lift.
2.2. The pumps can be used in a suction lift installation providing the height of lift is
within the limits specified in the limits of application section and the liquid to be
pumped is cold water.
2.3. Before deciding where to locate the unit, check to ensure the static outlet head
does not exceed the maximum requirements 12 metres (Ref fig 3).
2.4. A footvalve and strainer may be used, and the suction pipework size must
match the pump. In order to prevent solid particles from entering the electric
pump, the inlet pipe must be equipped with a filter.
2.5. Lay the suction piping over the shortest possible distance and ensure there is a
constant rise from the liquid source to the pump. Any high spots will cause air
pockets to form, reducing system efficiency.
Max. static outlet pressure 12m
