Submersible sewage pump with external macerator as submersible monobloc unit for stationary and portable wet well installation.
The outlet on the pressure side is designed as horizontal threaded connection or flange connection (depending on type). Open multi-channel impellers are used as the impeller shape.
Glanded motors give off their heat directly to the surrounding fluid via the housing parts and can be used in immersed state for permanent operation and, in some cases, for intermittent operation. Depending on the size, they can also be used in non-immersed state for short-term operation.
A oil barrier chamber protects the motor from fluid ingress. Depending on the size, it can be accessed from the outside and can be monitored with an optional sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable length is 10 metres. The cable inlet for the MTC 32 is longitudinally watertight. The three-phase motors have a bare cable end; AC motor are fitted with capacitor boxes and shockproof plug.
Fluid-side and motor-side sealing is available in different versions depending on the motor type: MTC 32 F…
…33.17 and …39.16: Mechanical seal on the fluid side, two rotary shaft seals on the motor side
…22.17, …26.17, …49.17, …55.13 and MTC 40…: Two independently operating mechanical seals
