Pumps offer reliability boost for paint
company
Larox pumps provided Tikkurila with a dry running capability, with no need for mechanical sealing.
Tikkurila, a Finland-based paint producer, installed its first Larox LPP65 pump in 2006 Three LPP65 and four LPP40 pumps are successfully operating today

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.
Novel peristaltic pump takes on all comers
The LPP peristaltic hose pump is capable of handling heavy, abrasive and aggressive slurries in mining and process industries as well as high viscosity fluids in hygienic and foodstuff applications.
The Larox LPP40 pumps are feeding emulsions to the dissolvers and to the finishing tanks.
The LPP65 pumps are feeding colour paste from the dissolvers to the finishing tanks.
After facing maintenance, environmental and process problems, Tikkurila decided to start trials with Larox pumps.
The previously used screw, lobe rotor and diaphragm pumps had both mechanical sealing, which wore down easily due to the hard binders in the paints.
Double diaphragm pumps tend to have a poor power ratio and were noisy.
The seal leakage created continuous maintenance problems.
As the pumped medium was then in contact with air, the paint hardened, making the maintenance work even harder.
The leaking wet paint on the floor also created a risk of injury to the employees.
Larox pumps provide a dry running capability, with no need for mechanical sealing.
As only the hose is in contact with the emulsion, the Larox pump does not have any mechanical sealing which might start to leak.
In Larox 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 Larox pump is also very gentle to the pumped medium and does not mix or shear it. Request a free brochure from Larox Flowsys ...
