Larox Peristaltic Pumps For Metering (Lpp-M)

Larox Pumps for Metering

The innovative Larox Peristaltic Pumps for Metering (LPP-M) set a new industry standard for peristaltic pump technology. Designed and manufactured for the industrial marketplace, they are ideal for pumping diverse slurries and metering a wide range of media.

Operating Principle

The operating principle of the LPP-M pump is based on peristaltic effect. There are two types of rollers in the rotor: squeeze rollers and centering rollers. Squeeze rollers push medium forward through the tube and centering rollers guide the tube to right alignment. As the squeeze roller rotates along the tube, the process medium gets pushed forward through the tube. At the same time, the tube behind compression point reverts to its original circular shape creating a suction effect at the pump inlet port. As a result, the tube bore gets filled with the medium. No backwards flow can occur as the tube is squeezed tight by the roller.
