Construction

Submersible sewage pump with external macerator as submersible monobloc unit for stationary and portable wet well installation in continuous duty.

Hydraulics

The outlet on the pressure side is designed as a horizontal thread connection/flange connection (MTC 40) or as flange connection (MTC 32). Open multi-channel impellers are used.

Motor

The motors available are surface-cooled motors in single-phase version (only MTC 40) and three-phase version for direct starting. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can operated immersed in continuous duty (S1) and non-immersed in short-time duty (S2) or intermittent periodic duty (S3).

Furthermore the motors are equipped with thermal winding monitoring. The thermal winding monitor protects the motor winding from overheating. Bimetallic strips are used for this as standard.

The connection cable has bare cable ends and is 10 m long as standard. The “A” model is equipped with a float switch and shockproof plug.

Seal

There is a sealing chamber between the motor and hydraulics. It is filled with medical white oil and protects the motor from media ingress by the seal on pump side. Pump-side and motor-side sealing is available in different versions depending on the motor type:

  • MTC 32F39.16: mechanical seal on the fluid side, two rotary shaft seals on the motor side
  • MTC 32F49.17, …55.13 and MTC 40: two independently acting mechanical seals

Delivery state

  • Pump
  • 10-metre connection cable with bare cable end
  • A version with attached float switch and shockproof plug

DORTMUND AS A LOCATION AS A MATTER OF CONVICTION Dortmund has established itself as Wilo’s headquarters. Besides the marketing investments in Borussia Dortmund, Wilo is also now investing significantly in Dortmund as a location. Here, where our success story started the Wilo Campus is now being built – currently Germany’s largest industrial building project. However, it is not an emotional or ideal driving this, it is a tough business decision. The argument for Dortmund is the market proximity to all of the production sites in Europe, the good infrastructure and the availability of well trained staff, so that the site is undisputed as a choice of location given its existing expertise.
