25evp80 pump is designed to work" pilot "at the final automated (sprinkling) modular pumping stations to support pressure in the tubular network in cases where the main pumps do not work. The pump can also be used in other areas, if the parameters and design allow this.
Pump 25evp80 - vertical, single -stage, centrifugal with submersible working bodies under the level of water. The working wheel is installed in the spiral case. The transmission of the torque from the engine to the working wheel is carried out by means of a shaft system consisting of two or three shafts interconnected by rigid couplings. The number of shafts and intermediate cases depends on the size of the pump. The shafts are installed on the radial bearings of sliding fixed in the tubular case, and in the upper node of the bearings, which consists of a radial and stubborn ball bearings. Lubrication and cooling of sliding bearings is carried out by a transported liquid. Lubrication of the upper node of the bearings is carried out by consistent lubricant.
