Wilo-Drain MTS Submersible Sewage Pumps
MTS Wilo Submersible sewage pump with inbuilt macerator as submersible monobloc unit for stationary and portable wet well installation.
Application | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Pumping of sewage containing faeces. Wilo macerator crushes solid impurities to the sizes allowing free medium pumping. Predominantly, pumps are applied at pressure wastewater disposal. Pressure wastewater disposal is used when the expenses of laying a conventional sewer pipe with free-flow conduit are too high, for example at:

Hydraulics
The outlet on the pressure side is designed as horizontal threaded connection (Rp 1¼" for MTS 40/21…27) or flange connection. Single-channel impellers are used as mpeller shapes.
Motor
Glanded motors give off their heat directly to the pumped medium via the housing components and can be used in immersed state for permanent and intermittent operation.
A sealing chamber protects the motor from medium ingress. The filling fluid used is potentially biodegradable and environmentally safe.
The cable inlet can be plugged in. Cable lengths are available in length increments of 10 meters.
Seal
Sealing on the medium side is achieved by a sliding mechanical seal not depending on rotation direction, while sealing on the motor side is achieved by a radial lip seal.
