Materials:

  • Casing of the hydraulic system: stainless steel 1.4301
  • Impellers: polycarbonate
  • Shaft hydraulic system: stainless steel 1.4104
  • Motor housing: stainless steel 1.4301
  • Motor shaft: stainless steel 1.4305

Description/construction

  • Submersible drainage pump for vertical or horizontal installation.

Hydraulics

  • Multistage submersible multi-stage radial impeller pump in split casing design. With integrated non-return valve. All parts in contact with pumped media are made of corrosion resistant material.

Electric motor

  • Corrosion-proof AC or direct-start, rewindable, oil-filled three-phase AC electric motor with self-lubricating bearings.

Cooling

  • Motor cooling is achieved by means of pumped liquids. The motor must only be operated in immersed state. Observe the maximum temperature limits for the fluids to be pumped. Vertical installation can be carried out with or without a cooling jacket - optionally. Horizontal mounting is done with a cooling jacket.
