Peristaltic Pump Adds Value
Larox FlowSys Oy (Lappeenranta, Finland) has introduced the LPP which it says is an innovation in the world of peristaltic pumping, saving energy and producing economic value in production cost efficiency by reducing maintenance and upkeep costs. Larox claims that with LPP, up to a 60% reduction in operating costs can be achieved.
There is a completely new operating principle since the hose is compressed only once per revolution. The advanced adjustment mechanism senses hose wear and the risk of over-compressing is minimised. These features give the LPP a much longer hose life.
The unique hose fixing system with reliable flanges at both ends of the hose enables secure and fast replacement of the hose. The clever operating principle of the pump, explains Larox, also allows it to operate continuously at high speeds and high flows without overheating. LPP can be easily installed in-line because of the smart construction of the pump. The high flow capacity of LPP makes smaller pump size possible and the pump requires less space compared to conventional peristaltic pumps. It also lowers spare part costs and lubrication needs.
Larox says the LPP can pump virtually anything and it widens the application range even further. The company says it is a perfect replacement for centrifugal units in mining and chemical industries where seals and glands cause dilution or leakage problems. Expensive centrifugal pumping stages can be replaced by one LPP pump with high-pressure capabilities in slurry pumping.
Currently, the LPP pump family consists of three sizes - DN25, DN 40 and DN 65 - for working pressure maximum 10 bar with flow capabilities up to 20 m3/h. LPP is also available with a sophisticated control unit including pressure safe limit, hose leak detector, frequency controller, emergency switch fuses, revolution counter and manual or remote speed control.
