New Progressive Cavity Pump Design Is Easy to Maintain

Progressive Cavity Pump DiagramProgressive cavity pumps have their place in pumping systems. But man, are they a bear to work on. Netzsch just released a new progressive cavity pump design that takes about 90% of the hassle out of maintaining their progressive cavity pumps.


In case you're not familiar with them, progressive cavity pumps are best suited for shear sensitive applications, like transferring fruits and vegetables. They're also great for handling abrasive and corrosive fluids. 

At the heart of every progressive cavity pump is a rotor and stator. As the single helix rotor revolves eccentrically within the double helix of the stator, a continuous cavity is formed and progresses towards the discharge end of the pump as the rotor rotates.

If you’ve ever worked on a progressive cavity pump, you know how difficult it is to replace the rotor or stator if something fails or the pump runs dry. The whole pump must be removed, repaired, and realigned after being reinstalled. It is a very tedious and time-consuming job.

That's where Netzsch's new design comes in.


This is really where Netzsch’s NEMO FSIP Progressive Cavity Pump shines. FSIP is an acronym for Full Service In Place, meaning you can service the pump while it is installed. Its design has been re-engineered to provide full access to all the wear parts without requiring any special tools. You can simply remove and replace all rotating parts without having to disconnect the pump from the piping or having to remove the motor.Netzsche NEMO FSIP Progressing Cavity Pump

The NEMO FSIP unit is especially useful where pumps are installed in wear-intensive environments requiring more service and maintenance work. The workload required to repair this pump is minimal, saving time and increasing profitability. We saw how easy it is to service this pump at WEFTEC 2015. Watch the demo video below to see for yourself.

Think the Netzsch NEMO FSIP progressive cavity pump might be right for one of your applications? Ask us about it! We gladly provide technical assistance to businesses in Wisconsin and Upper Michigan.
