Larox peristaltic pumps don't let the
paint dry
The Finland based paint producer Tikkurila has found significant benefits from installing Larox peristaltic pumps, particularly eliminating sealing problems, so has standardised on Larox
Tikkurila, Finland based paint producer, installed their first Larox LPP65 pump in 2006 As a result of good experiences of the Larox pump technology, further LPP65 and four LPP40 pumps are successfully operating today

The new LPP-M pump is ideal for accurate metering duties, with an exact flow per revolution, irrespective of the pipeline pressure, across the whole flow range
Pumping polyglycol as a cement additive
The Larox LPP-D15 pump was chosen for pumping polyglycol in the USA, as reliability and accurate dosing of this highly viscous fluid is essential for the cement making process
The Larox LPP40 pumps are feeding emulsions to the dissolvers and to the finishing tanks whereas the LPP65 pumps are feeding colour paste from the dissolvers to the finishing tanks.
Tikkurila decided to start trials with Larox pumps after facing maintenance, environmental and process problems on site.
The previously used screw and lobe rotor pumps used mechanical sealing, where the faces were easily damaged by the hard binders in the paints, and other double diaphragm pumps used tended to have a poor power ratio, and were noisy.
The seal leakage created continuous maintenance demands.
Also, as leakage of the pumped medium caused contact with air, the paint got hard making the maintenance work even harder.
The leaking wet paint on the floor was also a risk of injury to the employees.
The main advantages of Larox peristaltic pumps include a dry running capability and 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 ...
