Design

Submersible grinder pump with single-channel impeller for sewage as submersible monobloc unit for stationary and portable wet well installation. Motor available without (dry-motor) integral cooling system.

Application

Pumping of water containing domestic sewage. The Wilo macerator breaks up the solids into smaller pieces to produce an easily pumped fluid.

The MTS40 grinder pump is used typically in pressure sewer applications - both municipal and residential.

  • Pressure sewer, residence, camping site, etc.
  • Installation costs are reduced significantly due to the small pipe diameter, e.g. 1.6" (40 mm).

Technical data

  • Power connection: 1~230 V/60 Hz, 3~230 V/60 Hz or 3~460 V/60 Hz
  • Submerged operating mode: continuous duty (S1)Non-submerged operating mode: rated minutes operation (S2 or S3)
  • Protection class: Submerged under pressure (IP 68)
  • Insulation class: F
  • Thermal winding monitoring (normally closed contacts)
  • Max. fluid temperature: 37-104 °F (3-40 °C)
  • Cable length: 25 ft (8 m)
