industrial hopper pump


The hopper pump is an internal meshing rotary positive displacement pump. Its main working parts are the eccentric screw (rotor) and the fixed bushing (stator). Due to the special geometric shapes of the rotor and stator, several separate sealed cavities are formed. The operation of the rotor continuously and evenly transports the medium in each sealed cavity from the suction end to the discharge end. The internal flow rate is low, the volume remains unchanged, and the pressure is stable, so there will be no eddy current and agitation.

It can be used to transport neutral or corrosive liquids, clean or abrasive liquids, liquids containing gas or prone to bubble generation, high viscosity or low viscosity liquids, including liquids containing fibers and solid substances. It can work continuously for a long time and maintain a stable flow rate, and has good self-priming ability.

Because the stator is made of a variety of elastic materials, this pump is not suitable for conveying high-viscosity fluids and mediums containing hard suspended particles or fibers. Its flow rate is proportional to the speed. The transmission can be directly driven by a coupling, or by speed-adjusting motors, V-belts, gearboxes and other devices. This pump has few parts, compact structure, small size, and easy maintenance. The rotor and stator are the vulnerable parts of this pump, with a simple structure and easy assembly and disassembly.



Product advantages
