Self-priming pumps deliver higher heads

There are certain liquid transfer applications, such as irrigation and industrial refuelling, which require a pump to provide the important combination of delivering high heads and to be self-priming.
There are certain liquid transfer applications, such as irrigation and industrial refuelling, which require a pump to provide the important combination of delivering high heads and to be self-priming.
However, many self-priming pumps have an open-impeller construction and this limits the available pressure from the pump.
Alpha ORA-C series pumps, available through liquids handling specialists Pump Engineering, are designed to provide a low-cost, reliable solution to this problem.
A modified housing and closed impeller means that these pumps retain the characteristics of the self-priming centrifugal pump, with the ability to deliver high heads up to 100m (10bar(g)).
The Alpha range of centrifugal pumps are available as end suction or multistage and are supplied in sizes from 1.5 to 4in.
In addition to their ability of providing high heads, they are capable of delivering flow rates up to 3000 litre/min.
These robust pumps are available in cast iron, with cast iron or bronze impellers, stainless steel shaft and a wide range of mechanical seals.
They can be supplied as bare-shaft or motor-driven units with special versions available depending on specific application requirements.
