Rotary-Lobe-Pump Type PK

Rotační pístové dopravní čerpadlo (PK)

Basic Features:

The PK pump is designed as a modular construction system. It consists of a synchronous gear-head driving the rotary lobes contained in a pump body having suction and pressure ports and connestions.

The robust bearings are located in the gear head where they are protected from the pumped media by a mechanical sealing.Conversely,special seals containthe lubricating oil within the gear head.

Selection Criteria for the correct pump type:

The design of rotary lobe pump necessitates a clearence gap between the rotary lobes and the internal case profile, which produces the necessary slippage. However this only becomes significant when low viscous media is pumped under pressure. In this case ,the lower rotational speed range can’t be used.

This slippage is negligible in the case of product with viscosities of more than approx. 300cP. With these products, the volumetric efficiency is practically 100%.

Displacement:

The displacement of the PK pump is absolutely dependent on the viscosity and rotational speed. The displacement of the filled pump is able to cope with at least 8m water column or a vacuum of approx. mbar.
