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.

Proven tube from thermoplastic materials designed for chemical industry gives secure operating conditions for both environment and operators. Durable pump head and rotor material selections with optimized number of parts are ideal for corrosive operating environments. Rigid one piece rotor assembly enables one minute maintenance and easy cleaning of the pump head.

SUPERIOR ACCURACY FOR YOUR PROCESSES
Accuracy of metering in any application is the most vital property of a metering pump. Flow rate of LPP-M metering pump is not affected by variation of the discharge pressure condition. Positive displacement of the tube bore with zero slip provides same output volume on every cycle. The compression point of the tube acts as self-cleaning check valve without clogging risk providing clear flow path with no possibility for vapor lock.

OPERATING PRINCIPLE
The operating principle of the LPP-M pump is based on peristaltic properties. There are two types of rollers in the rotor: occluding rollers and guide rollers. The occluding rollers push medium forward through the tube and guide rollers center the tube for correct alignment. As the occluding roller rotates along the tube, the process medium gets pushed forward through the tube. At the same time, the tube behind the 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 backward flow can occur as the tube is always occluded tight by the rolle
