4.1 Application and area of usage
Progressing cavity pumps are self-priming,
rotating displacement pumps suitable for
pumping and metering low-viscosity and high-
viscosity liquids, neutral or aggressive liquids,
undiluted or abrasive liquids, liquids containing
gases, liquids prone to foaming, and liquids
with fibrous or solid particles.

performance data applicable to the pump.
4.4 Design
4.4.1 Structural design
Self-priming single, double, quadruple, or
eight-stage progressing cavity pump. Pumping
elements are the rotor and stator. A coupling
transfers the drive torque to the drive shaft, the
universal joint shaft, and the rotor.
External housing connection screws (clamp
bolts) hold together the discharge casing,
stator, and suction casing.
The stuffing box or mechanical seal casing is
located between the suction casing and the
bearing bracket.
4.4.2 Bearing and lubrication
Both sides of the drive shaft have liquid-sealed
encapsulated pin joints. Lubrication is provided
by joint oil.
The drive shaft bearings are angular contact
and groove ball bearings located in the bearing
bracket. The bearings are protected against
spray water.
