Pumpability is the Australian and New Zealand representative of the French company PCM Pompes. PCM is the original manufacturer of progressing cavity pumps and was started by Dr. Moineau, the inventor of the pump, in 1932.
Since that time PCM has developed a wide range of progressing cavity pumps up to 500 m3/h capacity or up to 200 bar discharge pressure for many applications across a great variety of industries.
The pumps are of robust construction for continuous industrial applications and when properly applied have very high levels of reliability and availability.
Applications in Process and General Industry
Progressing cavity pumps are typically used in applications characterised by one or more of the following:
- Low shear products requiring gentle handling
- Minimal flow disturbance, such as avoiding oils being emulsified in water
- Relatively low flow, high pressure applications
- Uniform flow
- Slurries and sludges
Applications in Water and Wastewater
Typical applications include:
- Sludge transfer
- Polymer transfer and dosing
Applications in the Food Industry
Hygienic versions of the PCM progressing cavity pump feature a flexi-shaft of a special highly elastic stainless steel that does not require any coating for corrosion protection, eliminating the possibility of coating separation and contamination.
Single piece shafts and rotors or special joining procedures eliminate or minimise potential contamination sites within the pump.
Many of these pumps are used in the Australian dairy industry.
Applications in Mining
Because of their ideal application to low flows and high heads, as well as their ability at slow speeds to handle abrasive products, progressing cavity pumps are often used in mine dewatering applications.
With discharge heads up to 800 metres available at 20 m3/h and to 2000 metres for small flows, these PCM pumps can be very useful in handling dewatering applications in single stage pumping from underground or open pit mines.
