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

Rexa MINI3-S03/M008-523/A
Efficient submersible sewage pump in non-clog design with macerator for house and site drainage for single and two-family houses.
The Wilo-Rexa MINI3-S grinder pump ensures safe house and site drainage. The compact design and the radial macerator with double shear effect allow you to safely drain small pump sumps, such as cesspools or catchment shafts. In addition, installation costs are reduced thanks to the use of the smallest-possible pipework. The high-quality motor has a double seal and is easy to maintain. The stainless steel motor housing is corrosion-resistant, even when non-immersed. Installation of the single-phase pumps is uncomplicated due to the low weight and the built-in plug: simply plug it into the existing socket. Pumps with an attached float switch start automatically. The pumps are switched on and off depending on the fill level.
Your advantages
- Excellent anti-clogging reliability due to radial macerator with double shear effect
- Optimised hydraulics/macerator combination for a wide coverage of delivery head at the lowest power requirement for domestic electrical installations
- Low overall installation costs thanks to the use of smallest possible piping
- Easy to use in domestic applications thanks to low weight.
- Long service life due to high-quality motor with double sealing
- High corrosion resistance, even with non-immersed motor, thanks to stainless-steel motor housing
