Electric pump NPX replaced by a 2/25 is intended for pumping of wastewater various chemically active and neutral liquids, including wastewater technological systems of nuclear power plants, with density not more than 1850 kg/m3. The pumped liquids allowed content of solid inclusions with volumetric concentration up to 0.1% with particle size up to 0,2 mm. The pump is available in seismic design basis. Seismic category III, II in accordance with NP-031-01.
Shaft seal-mechanical. The details of the flow part is made of steel, 12X18N9TL GOST 977 (material type «K»). As the drive is used asynchronous, special submersible, with squirrel-cage rotor engine.
