Description

Single-impeller electric peripheral pumps capable of developing high pressure as compared to a limited flow rate. These electric pumps are widely used in the nautical sector where they are commonly used to deliver fresh water (Cast Iron) or sea water (Bronze), to wash decks and chains, or to deliver pressurised water to onboard appliances such as showers, washbasins, toilets, etc. Automatic operation is achieved by equipping the pumps with small or medium-sized surge tanks

Installing a non-return valve at the suction inlet is recommended on a Peripheral pump

A peripheral pump is a niche product in-between a displacement pump and a centrifugal pump, in which the medium is pumped into a peripheral channel. Today, the peripheral pump has become crucial in many applications.

When the pump is started, the fluid is sucked through the suction flange directly into an annular channel in which the peripheral impeller rotates. The impeller consists of straight vanes that set the fluid into a circular motion. After passing through the annular channel, the fluid exits the pump through the outlet. In the annular channel, kinetic energy is imparted to the fluid by the vanes, increasing the fluid pressure. This working principle is very similar to how a side channel pump works.

Unlike ordinary centrifugal pumps, the characteristic curves do not flatten as the fluid flow decreases. The pump curves are rather straight lines with maximum heads at low flows and low heads at peak flows because a peripheral pump is a displacement pump.
