The Progressive cavity pump belongs to the group of volumetric rotary pumps.
The principle of the progressive cavity pump relies upon a “rotor” - helical metal screw - which rotates inside a “stator” - another helical part made of vulcanized rubber inside an iron cylinder - to make the fluid advance though a series of cavities along the axis of the pump.
Progressive cavity pumps do not require any particular maintenance: the parts subject to wear can be easily replaced on site and do not require the intervention of specialized personnel.
In addition to pumping challenging liquids for “heavy-duty” tasks, progressive cavity pumps are successfully used to pump delicate liquids or thixotropic products or solids in suspension, thus minimizing liquid aeration and agitation.
