The pump industry relies on expertise from a large and varied range of specialists, from experts in particular pump types to those with an intimate understanding of pump reliability; and from researchers who delve into the particulars of pump curves to experts in pump efficiency. To draw upon the wealth of expert knowledge the Australian pump industry has to offer, Pump Industry has established a panel of experts to answer all your pumping questions.

What are the benefits of using progressive cavity pumps for applications in the wastewater and sludge treatment industry? You’ll find out below.

Can progressive cavity pumps (PCPs) handle variable dry solids content sludge?


Yes, PCPs can successfully handle a wide variety of sludge applications with differing dry solids content because of their following characteristics:

  • Stable, variable flow rates
  • Minimal pulsation
  • Excellent suction lift capability
  • Flexible installation
  • Accurate metering of flocculants
  • High self-priming capabilities
  • Lower energy use


One of the industry’s concerns is reducing energy costs. Do PCPs offer any special solutions?


Progressive cavity pumps are known to operate very efficiently, which typically results in reduced operating costs.

Additionally, several PCP manufacturers have now incorporated new pump designs which offer reduced energy consumption, along with ease of maintenance, extended service life and significantly reduced life cycle costs (SEEPEX’s unique SCT is a good example of a modern progressive cavity pump innovation).


How well do PCPs work in pumping systems?


PCPs can be incorporated into numerous systems. They can be integrated into control systems to maximise productivity or used in connection with macerating, dosing, and/or chopping pumps.

From primary to thickened sludge, progressive cavity pumps provide the best pumping solution designed specifically for your application.
