Positive Displacement Pump

Midwest Machinery supplies several brands of Progressing Cavity (PC) Pumps. PC pumps have the ability to produce consistent pressure and volume over greater distances and lift than standard dairy effluent pumps, whilst using less power. This has made them extremely valuable in addressing certain design challenges.

The low power usage of a PC pump also enables farmers with power supply issues to gain more pressure and performance from their FDE system, without a costly upgrade of their power supply.

These pumps tend to be significantly more expensive than standard centrifugal pumps and are generally considered specialist pumps.

PC Pump Benefits:

  • Low power usage can help to eliminate the need to upgrade power supply to increase pumping performance.
  • High pressure/ long haul pumping can offer considerable project cost savings by utilising small bore pipe work and eliminating the need for a series of pumps, when pumping over long distances or with high head requirement.
  • High efficiency pump with low absorbed power (by as much as 50% lower compared to a centrifugal pump).
  • Solids handling of up to 10mm diameter.
  • Delivers consistent pressure at every hydrant enabling the depths of the Dairy Effluent to be accurately applied onto pasture.
  • Surface mounted option making it easier, cleaner and less hazardous for maintenance.
  • Ease of maintenance - Installing or dismantling on site, no need to send pump away for repair, reducing downtime.
  • It can be mounted vertically on a pontoon if required.
  • Low running speeds reduce wear for a longer working pump life which extends the period between routine maintenance.
