Peripheral pumps by Pedrollo

 Peripheral-impeller-designed pumps from Pedrollo of Italy are perfect for low-flow, high-pressure applications. The PK, PQ, and CK series make up the range. These units are extensively used in industry and domestic water reticulation systems.

A peripheral impeller is slightly different from the typical traditional understanding of a centrifugal pump design. The peripheral impeller transports fluid only along the periphery of the impeller disk and does not draw fluid into the center. Operating more like a turbine than a centrifugal type pump.

The very tight clearance between the impeller and housing means the peripheral pump is not designed for solid handling in any way. The higher-pitched sound from a peripheral pump is a typical characteristic of this type of pump design.

The PKm 60 Pedrollo pump is a huge favorite of the domestic market due to its effective, low-cost, high-quality, and efficient design. The unit is very popular in small domestic water systems where users need to automate two taps.

Coupled to an automatic controller, this is an ideal solution for rainwater or water storage tank water supply automation.

Small boiler and hot water transfer pump systems are the target market for the peripheral pump sector. Pedrollo has a huge range of units, from the PK end-suction to the PQ side-suction-designed pump units.

With pressure capability up to 10 bar, this low-cost pump range is ideal for the cost-conscious OEM needing a small pump for production projects.
