The Larox peristaltic pumps (LPP-D) are suitable for pumping diverse slurries and dosing a wide range of media.
The principle of the LPP-D pump is based on the peristaltic effect.
A singlebearing-mounted roller presses against the hose only once per the 360 degree operating cycle. LPP-D pumps incorporate advanced rolling design which eliminates frictionminimises hose wear and lowers energy consumption.
Compared with traditional hose pumpsthe LPP-D can double the flow per hose compression (best P/100 factor).
The original Larox operating principle has been retained in developing the LPP-D peristaltic hose pump.
As the cylindrical rotor rotates along the hosethe process medium gets pushed forward in the hose bore. At the same timethe hose behind the compression point reverts to its original circular shape creating a suction effect at the pump inlet port.
As a resultthe hose bore gets filled with the medium. No backward flow can occur as the hose is squeezed tight by the roller.
The roller is mounted on a crankshaft to enable eccentric movement.
