Ebara peripheral pumps use a turbine-type impeller to achieve notably higher heads at low flow rates than a standard centrifugal pump of equivalent size and power. The range is currently represented by the PRA and PRN series, cast iron peripheral pumps suitable for domestic water supply, boiler feed, and autoclave pressurisation.
Unlike a centrifugal pump, a peripheral pump circulates liquid around a narrow annular channel multiple times as it passes through the pump, building pressure with each pass. This allows small pump bodies to generate heads that would otherwise require a multistage centrifugal design. The trade-off is lower flow capacity, making peripheral pumps best suited to applications requiring high pressure at modest flow rates.
Ebara peripheral pumps are compact, lightweight, and notably quiet in operation. They are a practical choice for residential installations where space, noise, and ease of handling are priorities.

A peripheral pump uses a turbine-type impeller to circulate liquid around a narrow annular channel, building high pressure across a compact pump body. It is suited to applications requiring high head at low flow rates.
Choose a peripheral pump where high pressure is required at modest flow, for example, boiler feed, autoclave pressurisation, or domestic supply from a tank. A centrifugal pump is a better choice where higher flow rates are needed.
Domestic water supply, boiler power supply, and autoclave pressurisation units are the primary applications. They are not suited to high flow duties.
Yes, Ebara peripheral pumps are specifically noted for their silent running, making them a practical choice for residential and noise-sensitive environments.
