Description de la série de fabrication

Construction

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.

Domaines d'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).

Description/construction

Submersible grinder pump as submersible monobloc unit with internal patented macerator cast in AISI 440B+Co solid stainless steel. Pump is designed for wet pit installation on guide rails or for use in portable applications in intermittent operation.

Hydraulics

The outlet on the pressure side is designed as a horizontal threaded or flange (for MTS 40E…) connection with a discharge size of 1.6" (40 mm). Double shrouded single-channel impellers are used in the design.

Motor

Glanded motors conduct heat directly to the surrounding fluid via the housing components and can be used in submerged state for permanent and intermittent operation.

A sealing chamber protects the motor from fluid leakage. The filling fluid used is biodegradable and environmentally safe.

Cable lengths are available in fixed lengths measured in 25 ft (8 m) intervals.

Sealing

Sealing on the fluid side is done using a bidirectional mechanical seal. For type MTS 40… , the seal used is a rotary shaft seal and for type MTS 40E…, it is a bidirectional mechanical seal.
