Pumps

The Kudu Progressing Cavity Pump consists of two parts, the stator and the rotor. The stator being stationary and the rotor is the rotating part. It is a positive displacement pump without valves and it delivers a consistent flow. The rotor is driven from the surface through the rod string or the sucker rods and the stator is attached to the tubing string. The PC pump can be described as a gear pump with an external-tooth gear (the stator) running in an internal-tooth gear (the rotor). The rotor is a single threaded helix and the stator is an elastomer lined double threaded helical cavity.

The rotor turns eccentrically in the stator forming cavities from the beginning of the flow to discharge at the end of the pump. The flow rate is proportional to the size of the cavity, rotation of the rotor and the pressure across the pump. The elastomer is the heart of the PC pump. Kudu has been partnering with PCM (www.pcmpompes.com) for 15 years to provide elastomers that will fit all the specifications of an application.
