The innovative Larox LPP-D peristaltic pumps for dosing claim a new industry standard for peristaltic pump technology.
The innovative Larox LPP-D peristaltic pumps for dosing claim a new industry standard for peristaltic pump technology.
Designed and manufactured for the industrial marketplace, they are ideal for pumping diverse slurries and dosing a wide range of media.
A single, bearing-mounted roller presses the hose only once per the 360 degree operating cycle, producing the maximum flow per revolution.
Compared with conventional peristaltic pumps, the LPP-D doubles the flow per hose compression.
LPP-D pumps incorporate advanced rolling design which eliminates friction, minimises hose wear and lowers energy consumption.
The operating principle of the LPP-D pump is based on the peristaltic effect.
As the cylindrical rotor rotates along the hose, the process medium gets pushed forward through the hose.
At the same time, the hose behind the compression point reverts to its original circular shape creating a suction effect at the pump inlet port.
As a result, the hose bore gets filled with the medium.
No backward flow can occur as the hose is squeezed tight by the roller.
The LPP-D incorporates the unique operating principle with rugged design, advanced material and elastomer technology.
LPP-D pumps provide substantial savings through improved process performance, long service interval and low maintenance costs.
The LPP-D pumps offer quality and benefits that no other pump comes close.
The LPP-D pumps have a high turndown ratio making them ideal for dosing and flow control.
They provide accurate dosing in all process conditions as the pump discharge flow does not depend on the pipeline pressure.
The LPP-D pumps are compact in design and require only a small footprint.
With the unique rolling design and 360 degree operating cycle LPP-D pumps offer extended hose life, no overheating even at continuous maximum flow rate, only one compression per revolution, higher flow per hose compression than any other peristaltic pump and in-line pipe connection.
The LPP-D pump is available in sizes LPP-D15, LPP-D20 and LPP-D25 for maximum pressure of 7.5bar, and with flow capacities up to 2m3/h.
The high-grade LPP-D pump hose materials range from chemical resistant ethylene propylene to various other elastomers and rubber compounds.
