Pumps handle challenges of Latex paint
Seal-less LPP pumps will not get damaged even if they run dry for longer periods of time.
Larox Flowsys has supplied eight LPP65 pumps to Alcro-Beckers, a Swedish paint producer The Larox pumps have been successfully operating since the start up of a new Latex paint factory in 2007

Pinch valves manufactured and supplied to ISO9001
Larox Flowsys gained ISO9001 certification in 1997 and is the only known pinch valve manufacturer that has been awarded this quality certificate for all of its operations.
LPP pumps were chosen over screw pumps for feeding emulsions to the dissolvers and to the finishing tanks.
When a screw pump is run dry, the mechanical sealing, stator and rotor assembly will be often damaged.
The binders in the Latex emulsions become very hard if they are in contact with air.
As the mechanical seal wears, it starts to leak and create maintenance and environmental problems to the process.
With Larox pumps only the hose is in contact with the emulsion.
This isolates the pumped medium from the air.
Seal-less LPP pumps will not get damaged even if they run dry for longer periods of time.
In LPP pumps the cylindrical rotor rotates along the hose and the process medium gets pushed forward through the hose.
At the same time, the hose behind the compression point reverts to its original 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 pump does not mix or shear the substance being pumped. Request a free brochure from Larox Flowsys ...
