Food Grade High Pressure Rotary Lobe Pump with Safety Valve

sanitary lobe pump are used in a variety of industries including food, beverage, pharmaceutical, chemical and biotechnology. They offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics

Operating Principles

The cam-type double-rotor pump is a multi-purpose two-way displacement pump manufactured with advanced technology.

The professional manufacturing technology and manufacturing precision of the product have reached the international 

advanced level. This product adopts two synchronously rotating rotors,which are driven by a pair of synchronous gears in 

the box.The rotors are driven by the main and auxiliary shafts to rotate synchronously in opposite directions to change the

volume of the pump,thus forming a higher vacuum.The temperature and discharge pressure are especially suitable for 

the transportation of sanitary media and corrosive high-viscosity media.Cam rotor pumps are divided into two major series:

sanitary grade and corrosion-resistant type according to manufacturing standards; in terms of structure, they are divided

into two categories: high pressure and high viscosity and high pressure and low viscosity.The core components and

sealing device of the product are manufactured with different materials and different sealing forms according to the 

different characteristics of different media,which improves the professional conveying performance of the product.Cam 

rotor pumps are widely used in petrochemical, fine chemical, daily chemical, pharmaceutical, food, environmental 

protection, papermaking, chemical fiber, paint, metallurgy, oilfield and other industries.
