Electroly-loaded modernized type < Strong Style = "Margin: 0px; Padding: 0px;"> NV-M designed for pumping from underground drainage containers and water mixtures with oil products.
design
A modernized semi-loading unit of the type nv-m -an unit with a vertical axial outline of the environment to an open-type working wheel and with a spiral extension of the body through the pipe pressure to the supporting plate . The running part of the pump (the working wheel with the body) is separated from the chassis of the oil chamber with a double end seal. The supports of the rotating shaft are rolling bearings that do not require additional lubrication during the entire service life. The shaft is located in hermetic suspensions and is driven by an engine through a coupling with stars. The tightness of the pendants is provided by the end seal and controlled by the float sensor. A change in the depth of immersion is achieved by a change in the length and number of pendants.
