Larox are the benchmark in abrasion resistant pump and valve technology
The operating principle of the Larox LPP-T 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
Standard peristaltic pumps use rotors that have multiple plates or shoes that slide against the pump hose to create flow. This causes friction and heat, in some sludge treatment processes, heat is already present due to biochemical reaction. This combination of friction and latent heat prevents pumps being operated continuously, reduces hose life, increases service intervals and down time, they also require high levels of lubricants inside the rotor chamber.
All of these factors incur additional cost to YOU

We will stock replacement hoses for your pumps
The Larox pump has a single roller that contra-rotates during operation, this eliminates friction and minimises heat, enabling the pump to run continuously, at temperature with minimal quantities of lubricant. The single roller design is also extremely efficient in comparison to other designs.
A single, bearing-mounted roller presses against the hose only once per the 360 degree operating cycle, producing the maximum flow per revolution and offering the longest lifetime possible

Larox unique hose design and hinged access panel, allows speedy replacement using pre-formed hoses, even the largest hoses can be changed in half an hour. This means an end to trying to feed straight lengths of rubber hose through small appertures taking hours to complete.
