The single-stage vertical pumps with double entry impeller are designed to handle liquids chemically inert, free of mechanical admixtures, with temperature up to 80°C. Electric motor is mounted to the pump either with the help of sleeve-type couplings or transmission shaft which consists of several parts joint by clutches.
      This type of pumps is widely used for water-supply, irrigation in agriculture and other purposes in industry.
      Compact design of pumps type DV allows to use them at small pumping stations
