NETZSCH welcomes new pumps

Published by
Hydrocarbon Engineering,

NETZSCH Pumps North America, LLC has added to its line of full service-in-place (FSIP) NEMO® progressive cavity pumps. The maintenance-friendly FSIP™ design has been re-engineered to provide full access to all the pumps’ rotating parts. These pumps are now available in six sizes (NM045 to NM105) for flow rates up to 700 gal./min. The models are now offered with differential pressures up to 90 psi (1-stage) up to 180 psi (2-stage). S, L, D and P geometries are available.

Users can conveniently open the in-service pump housing, dismantle all rotating parts, and install them again without having to remove the pump from the pipe assembly or having to disconnect wiring. The 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 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 minimised. In addition, the pump’s installation footprint has been reduced for both conventional stators and the newer iFD-Stator®.

The pump design is fully compatible with the existing NEMO pump BY and SY series. Using 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.

This range of 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.
