NETZSCH Pumpen & Systeme GmbH has added to its line of FSIP (full service-in-place) NEMO progressive cavity pumps.

The FSIP design has been re-engineered to provide full access to all the pumps’ rotat-ing parts. NEMO FSIP is now available in six sizes (NM045 to NM105) for flow rates up to 180 m3 per hour. NEMO FSIP models are now offered with differential pressures up to 6 bar (1-stage) up to 12 bar (2-stage), identical to the performance parameters of the standard series.

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.

The pump is available in numerous styles with four rotor/stator geometries 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.
