Wilo-Drain MTC

Submersible wastewater pumps with macerator

Pumping of sewage containing faeces, as well as municipal and industrial sewage with long-fibre constituents, from individual buildings and for commercial utilisation. The macerator breaks down the solid constituents into smaller pieces to generate a readily pumpable medium.
Special features/Product advantages
  • Oil isolation chamber
  • High efficiency
  • SiC mechanical seal on pump side
  • Longitudinal watertight cable
  • Version witht Ex protection (optional MTC 32)

Description/Design
Monobloc submersible waste water pump with macerator for vertical wet sump installation; three-phase asynchronous motor 3~400 V, 50 Hz or single-phase AC motor 1~230 V, 50 Hz, protection class IP 68, protected by thermal winding contacts, insulation class F; motor shaft mounted in permanently lubricated, low maintenance roller bearings
  • Shaft sealing: mechanical seal on motor side which is independent of direction of rotation (exception MTC 32 F 39.10: sealing on motor side with 2 radial shaft seal rings), mechanical seal on pump side which is independent of direction of rotation; oil-filled intermediate chamber serves as cooling and lubrication
  • Hydraulics: open multi-channel impeller (MTC 40 Vortex impeller) in conjunction with macerator allows clogging-free pumping and optimum efficiency
