Flowrox Progressive Cavity Pumps Extend Stator Lifetime

Deer Island found with competitor’s pumps that every time they needed to replace the stator, they also needed to replace the rotor. They started looking for other options and decided to try Flowrox screw pumps (progressive cavity – PC pumps). Since the start-up of Flowrox PC pumps (EL-series) in May 2014, the plant has only replaced two rotors.

Flowrox screw pumps extend stator lifetime from 5-8 weeks to 6-8 months

The plant asked Flowrox to prepare progressive cavity pumps to extend stator lifetime. At first, Flowrox stators were lasting 5-8 weeks which was an improvement from the competition but not by much. The plant worked with Flowrox engineers to alter the stator durometer which resulted in a stator lifetime of 6-8 months at Deer Island. After the alteration, the stator lifetime was extended from 5-8 weeks to 6-8 months. Annual maintenance cost savings are approaching $100K over competing progressive cavity pumps.

In addition, the operators appreciate how quietly the Flowrox PC pumps run. Flowrox screw pumps operate at a lower RPM (140 RPM vs. 300 RPM) than competitive pump while producing a significantly greater average flow rate (248 GPM average vs 172 GPM average).

More about screw pump EL-series

The Flowrox EL-series PC pump is ideal for environmental applications: demanding water, wastewater and municipal waste applications. It includes maintenance hatches in suction pipe so it is easy to remove any clogged substances. The EL-series progressive cavity pump performs best in low pressure applications with high flow rates, typical for environmental applications. Four different sizes are available: EL50, EL100, EL200 and EL330, all with optional chassis.

Flowrox EL-series PC pump ensures:

  • Easy installation, fluent operation and quick maintenance
  • Clog removal is easy through maintenance hatches
  • Low life cycle costs
  • High flow rates
  • Low pressure applications
