Progressive cavity pump is very suitable for conveying single or mixed multiphase medium which are neutral or corrosive, clean or abrasive, gassy or easy to produce bubble, high or low viscosity, abundant/without solid and fiber particles. Widely applied in field of environmental protection, petroleum, chemical, food and beverage, paper and pulp, construction, mining and agriculture.
Progressive cavity pump, as a type of positive displacement pump, works based on the interference fix between the stationary stator and the eccentric running rotor. This interference movement forms several separated and air-proof cavities, running from the inlet to outlet along the axis because of the rotor's rotation, which results in the medium's continuous conveyance in cavitie
Key characteristics of Subtor progressive cavity pump
1.High efficiency, energy saving
2.Mechanical efficiency up to 65%-85%
3.Volumetric efficiency up to more than 95%
4.No pulsation, no shear or compression, no damage to medium's physical property
5.Lower vibration and noise, continuous conveyance
6.Flow rate is strictly proportional to rotating speed, suitable for metering
7.Very suitable to transport medium with gas or solid
8.Excellent self-priming capacity, suction height 3-5 meter water column
9.Various installation position doesn't affect pump operation
10.Simple structure, easy to maintain, no special tools required for maintenance
