WHAT IS A PERIPHERAL PUMP?

Peripheral pumps, also referred to as regenerative pumps, are centrifugal pumps whose impeller rotates in a largely concentric casing channel with an inlet and an outlet opening. The fluid in a peripheral pump is pumped into a peripheral channel (around the edge of the casing).

Unlike standard centrifugal pumps, the curves do not flatten as the fluid flow decreases. To summarise the fluid moves along the circumference for the inlet to the outlet of the casing with increasing pressure. Peripheral pumps are suitable for pumping uncontaminated liquids, e. g. as boiler feed pumps for small boilers, as pressure boosting pumps, car wash pumps, as pumps for the chemical industry and for all applications in which low flow rates have to be pumped at high pressure.
