Sanitary Stainless Steel Food Grade Mini Rotary Lobe Pump for High Viscosity Honey.

sanitary food grade lobe pump is the best solution for pumping viscosity medium, such as honey, chocolate, Peanut Butter, etc.

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.
