Greater flow rate with lower RPM
Since the installation of six Flowrox™ progressive cavity pumps in 2013 the customer has dramatically increased the volume of processed wastewater annually. Flowrox PC pumps operate at a lower RPM than competitive pumps while producing a significantly greater average flow rate. The operators also appreciate how quietly the Flowrox PC pumps run.
Deer Island Waste-Water Treatment Plant services 2.5 million people in Metro Boston area and process an average of 370 million gallons (1,4 million m³) of wastewater a day. They had been utilizing progressive cavity pumps for several years in their processes. The plant operators had faced the fact that with competitor’s pc pumps they always needed to replace also the rotor together with the stator. They determined that if they could find a pump where they only had to replace the stators they could achieve great savings annually. A specification was written around Flowrox™ pumps that included nitride coating on the rotors as well as 2D geometry rotors and stators.
Slower rotation speed guarantees less wear.
When the Flowrox PC pump performance is compared with conventional PC pumps, Flowrox 2/3 geometry pumping elements need less RPM than conventional 1/2 geometry pumping elements to achieve the same flow rate.
In October 2013 six (6) Flowrox pc pumps plus spare parts were delivered. Since then the plant has been able to reduce drastically the amount of monthly spare part orders. Savings on pc pump spares are estimated to be $20K a year which in the long run has turned to ~ $160K during the past 8 years.
Your benefits
Over 30% higher pumping capacity compared to a conventional PC pump with the same rpm.
Save energy up to 15% compared to a conventional model.
Minimized maintenance time enables the highest run time possible.
Through advanced technology and precise design, Flowrox™ PC Pump offers you significant cost savings by reducing pumping cost.
Compared to conventional technologies, a Flowrox PC Pump delivers more pressure, more capacity and overall – more efficiency.
The Flowrox EL-series PC pumps are ideal for demanding water, wastewater and municipal waste applications. They ensure:
- Easy installation, fluent operation and quick maintenance
- Clog removal is easy through maintenance hatches
- Low life-cycle costs
- High flow rates
- Low-pressure applications

Flowrox™ progressive cavity pumps: E-, EL- and D-series
Flowrox progressive cavity (PC) pumps are ideal for challenging applications with high viscous, corrosive and other difficult or sensitive media. Flowrox PC pumps are divided into three series. E-series is ideal for industrial and paste pumping applications. EL-series PC pumps excel in demanding wastewater and municipal waste applications. D-series progressive cavity pumps are designed especially for chemical and flocculant dosing applications.
Spare parts for Flowrox™ pumps
Flowrox has a wide selection of spare parts for own peristaltic pumps (hoses, tubes, etc). We also manufacture and deliver spare parts for all PC (progressive cavity) pumps - stators, rotors, drive shafts, coupling rods, joint assemblies, bearings sets and sealings.
Reliable pumping solutions
Flowrox industrial pumps serve a wide range of process industries. Peristaltic hose pumps and progressive cavity pumps are specifically designed for demanding processes involving abrasive, corrosive, highly viscous or crystallizing media with high solids content.
Steady and reliable feed ensured at a chemical plant in Germany with Flowrox pumps
CURRENTA is managing and providing services to CHEMPARK in Leverkusen, Germany. All of its hazardous waste incineration plants were using conventional filter presses to separate solids from waste water generated by flue-gas scrubbing. In 2009, CURRENTA started a modernization project to replace the existing filter press installations. Nowadays, Flowrox™ LPP-T peristaltic pumps feed fully automatic filter presses for flue-gas scrubbing process in this German chemical plant.
Rubber hose solves scaling issue -Increased uptime and process efficiency with Flowrox pumps
A smelting plant in Norway had a scaling problem. Their spill process water contains lots of carbonates which caused reoccurring damage to the previously used centrifugal pump. Another challenge for the new pump was to also empty the 3-meter-deep tank located underneath the pump’s location.
