Cavity Pumps


Other features of PC pump

 

  • High efficiency, low energy:
    Volume efficiency can reach over 96%
  • No pulsation, low noise and continuous
    operation
  • Strong suction capacity, the suction lift can
    reach 8m
  • Simple structure, easy maintenance
 

Progressive cavity pump

 

The pumps depends on the sealed chambers, which are formed by the interference fit between eccentric rotating rotor and stationary stator, are moved along the axial direction from pump's entry end to outlet when the rotor is rotating in the stator. Then the media within the seal chambers can be conveyed from the entry end to the outlet, thus the pump's conveyance process can be realized.

Suitable for conveying the media with the following properties

 

  • High content of solid, the solid content of sewage can be up to 45%
  • Different viscosities up to 100,000mPaS
  • Fibrous materials
  • High shear sensitivity and easily destructives
    from centrifugal forces
  • Multiphase mixture of gas, solid and liquid
