The centrifugal vertical ship pumps type are designed to handle clear and seawater, or other fluids with viscosity, specific gravity and chemical aggressiveness similar to water. The maximum temperature of handled fluids is 85°C.
      KV pumps are intended for ship facilities such as
      - circulation systems
      - cooling systems
      - fire fighting systems etc.
      KV pumps are single-stage or double-stage centrifugal split-case end-suction (pump type 280KV20 however is double suction). The shaft rests in two ball bearings which are fitted in the top and bottom sections of the pump.
      The pumps are coupled to the electric motor by means of a flexible claw coupling.
      The direction of rotation of the impeller is counter clockwise looking from the driving side.

      The indication of the pumps includes the following symbols:

28KV55x2

28	-	rated flow (l/s)
KV	-	ship vertical pump
55	-	rated head per stage
2	-	number of stages
