The NEMO® progressive cavity pump is the new entry of Netzsch Pumpen & System's full-service-in-place line of pumps. The maintenance-friendly FSIP™ design has been re-engineered to provide full access to all the pumps’ rotating parts. Ideal for wear-intensive applications, the NEMO FSIP is now available in six sizes (NM045 to NM105) for flow rates up to 180 m3 per hour. NEMO FSIP models come with differential pressures up to 6 bar (1-stage) up to 12 bar (2-stage), identical to the performance parameters of the standard series.
Users can conveniently open the large inspection cover of the 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, 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 sys-tem 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 numerous styles with four rotor/stator ge-ometries and a selection of engineered joints and sealings that can be tailored to suit specific applications. Conveyance volumes can be calculated in proportion to rotation speed, with high dosing precision over the entire rotational-speed range.
