Rotary Lobe Pump


Rotary Lobe Pump PL series pumps have been specially designed to make dismantling (whether for inspection, cleaning and maintenance) quicker and easier. The forward seal position places the seals in direct contact with CIP fluides. Superior seal cleanlines lengthens seal life and minimizes seal flaking (prodcts contaminations). Because the seals are located directly behind the rotors, areas of product entrapment are eliminated for superior hygienic performance. 

Unique front loading seal design gives faster maintenance, easier cleaning and less downtime. The only dismantling front cover, the rotors and seals are take out without pump dismantling from pipe. 

PL series pumps have been working to suit all hygienic pumping applications in the food, diary, beverage, pharmaceutical and another places where the stainless steel is resistant to liquids to be pumped.

Working Principle


PL series pumps are positive displacement pumps. The volume at the inlet increased when the rotors rotate and the product is drawn into the pump. It is then transported in the space between the lobes and the periphery of the pump housing to the discharge side. The volume between the rotors are reduced here and the product in forced out through the outler.
