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.
