DN – Drainage pumps for dirty water

The DN pumps are submersible electric pumps for drainage of clean and slightly dirty water.

The DN pumps are drainage pumps with up to 22 metres head and up to 280 l/min (16,8 m3 /h) delivery. This range consists of three pumps with up to 0,75 kW rated power.


APPLICATIONS

  • Draining of flooded excavations and marshy ground.
  • Irrigation from rainwater resevoirs, ditches, ponds and watercourses.

SPECIFICATIONS

  • Maximum liquid temperature: 50°C with fully submerged pump. 25°C with partially submerged pump.
  • Open impeller with abrasion- resistant rubber coating.
  • Mechanical seal protected by sand labyrinth.
  • Maximum dimension of suspended solids: 5 mm.
  • Motor in a dielectric non-toxic oil bath, which ensures the lubrification of the ball bearings and a more efficient cooling.
