Progressive cavity pump re-engineered to ease dismantling

Netzsch Pumps North America has added to its line of FSIP (full service-in-place) progressive cavity pumps. Ideal for wear-intensive applications, the maintenance-friendly FSIP design has been re-engineered to provide full access to all the pumps’ rotating parts. NEMO FSIP is now available in six sizes (NM045 to NM105) for flow rates up to 700 gallons per minute (gpm). NEMO FSIP models are now offered with differential pressures up to 90 pounds per square inch (psi) (1-stage) up to 180 psi (2-stage). S, L, D and P geometries are now available.

Users can conveniently open the in-service pump housing, dismantle all rotating parts, and simply install them again without having to remove the pump from the pipe assembly or having to disconnect wiring. The NEMO’s rotor-stator unit can be lifted out after opening the newly designed inspection cover on the pump housing – without the need for any special tools. This significantly reduces installation and maintenance time.

 With the new FSIP pump, all wearing parts – from flange to flange – can easily be replaced when opening the pump. Because the rotor-stator unit can be removed either sideways or from above, service time is minimized. In addition, the pump’s installation footprint has been reduced for both conventional stators and the newer iFD-Stator.

The NEMO pump with FSIP design is fully compatible with the existing NEMO pump BY and SY series. Using NEMO FSIP conversion kits, all previously installed 1 and 2-stage NEMO pumps in sizes NM045 to NM105 can be retrofitted without any changes to the previous system or pumping characteristics.

 NEMO progressive cavity pumps are known for their continuous, pressure-stable, gentle and low-pulsation conveyance of almost any process fluid without being affected by fluctuations in pressure and viscosity. The pump is available in eleven styles with four rotor/stator geometries and a selection of engineered joints that can be tailored to suit specific applications. Conveyance volumes can be configured in proportion to rotation speed, with high dosing precision over the entire rotational-speed range.
