www.rockproducts.com ROCK products • March 2018 • 71 EQUIPMENT & TECHNOLOGY PUMPS & MOTORS Gorman-Rupp is introducing a new line of cost-effective priming-assisted centrifugal pumps. The ValuPrime is a com- pact and powerful pump ideally suited for the dewatering needs of the construction, industrial and agricultural markets and is based on the proven technology of the Prime Aire and Prime Aire Plus lines. Featuring model sizes 4- x 4-in. (100 mm x 100 mm) and 6- x 6-in. (150 mm x 150 mm), flows to 1520 gpm (95.9 lps), total dynamic head to 150 ft. (45.7 m) and solids handling capabil- ities up to 3 in. (76.2 mm), these pumps provide the high level of performance you've come to expect from Gorman-Rupp. The new VPA Series pump line comes standard with a 34-gal. fuel tank, programmable control panel, EPA-compliant Isuzu Final Tier IV diesel engine, and a one-year factory war- ranty. These pumps are ideal for floodwater/storm standby, general job site dewatering, river and dam bypass oper- ations, dust control and for water and street department applications. The Gorman-Rupp Co. manufacturers pumps and pump- ing systems for the municipal, water, wastewater, sewage, industrial, construction and original-equipment manufac- turing markets. Gorman-Rupp, www.grpumps.com Netzsch Adds Sizes to Version of NEMO Progressive Cavity Pump Netzsch Pumps North America added to its line of FSIP (full service-in-place) industry-leading NEMO 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 gal. per minute (gpm). NEMO FSIP models are now offered with differential pressures up to 90 lb. per sq. in. (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, dis- mantle 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 side- ways 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 contin- uous, pressure-stable, gentle and low-pulsation conveyance of almost any process fluid without being affected by fluctu- ations in pressure and viscosity. The pump is available in 11 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.
