Your advantages
  • High efficiency and operational reliability thanks to the optimised hydraulics
  • Easy installation – even in narrow drainage pits – thanks to its lightweight, compact design with integrated condenser and threaded flange
  • Reliable use in a variety of drainage applications thanks to the corrosion-free impeller and sealed cable inlet
  • Longer maintenance intervals thanks to the high-volume sealing chamber and double seal
  • Quick maintenance facilitated by direct access to the sealing chamber and pump housing
The reliable wastewater and sewage pump for household and groundwater drainage
The Wilo-Rexa MINI3 is the ideal submersible pump for standard sewage in site drainage and domestic situations. Its 40mm free ball passage makes it suitable for pumping wastewater and sewage free of faeces. The pump can be used flexibly for both stationary and portable wet well installations. If the pump is installed in the DrainLift WS 50 pump chamber, sewage with faeces can be pumped: the system has an approval according to EN 12050-1. The optimised hydraulics provide high levels of reliability for universal application in the pumping of a diverse range of fluids. Its compact design means it can even be installed in narrow drainage pits. The oil-filled sealing chamber and a double seal allow for longer maintenance intervals. Direct access to the most important components makes carrying out maintenance work very convenient.

Construction
Submersible sewage pump for intermittent operation for stationary and portable wet well installation.

Application
Pumping of:
  • Sewage not containing faeces

Description/construction
Submersible sewage pump as submersible monobloc unit for portable wet well installation in intermittent operation.

Hydraulics
Pump with vortex impeller and a free ball passage of 40 mm. Pressure connection as a vertical threaded connection.

Motor
Surface-cooled motor in single-phase version (with built-in operating capacitor) and three-phase current version for the direct starting. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can be operated immersed in continuous duty (S1) and non-immersed in intermittent operation (S3).

The motor is equipped with automatic thermal motor monitoring. This means that the motor is switched off if it overheats and is automatically switched on again once it has cooled down.

The connection cable has a length of 5 m or 10 m and is available in the following versions:
  • With bare cable ends
  • With plug
  • With float switch and plug
Seal
The seal is created on the fluid side by a mechanical seal, and on the motor side by a rotary shaft seal. A sealing chamber with a white-oil filling is located between the gaskets.

DRAIN ALARM
Item no.: 2545133

Network-independent alarm switchgear (self-charging power supply unit) for wall fixation with optical and acoustic alarm signal. 
LEVEL SENSOR 0-1MWS, 10M CABLE
Item no.: 2519924

Level sensor with ATEX approval for level control in sewage water containing faeces. A level sensor is used here to measure the hydrostatic pressure in the medium and to convert it directly in the pressure transducer into an electrical signal by means of a diaphragm. The signal is transmitted to the switchgear and evaluated accordingly.
LEVEL SENSOR 0-2,5mWS, 10m CABLE
Item no.: 2519921

Level sensor with ATEX approval for level control in sewage water containing faeces. A level sensor is used here to measure the hydrostatic pressure in the medium and to convert it directly in the pressure transducer into an electrical signal by means of a diaphragm. The signal is transmitted to the switchgear and evaluated accordingly.
FLOAT SWITCH WA 65 (PSN-O) 5M
Item no.: 503211390

As a signal transmitter for the system switching, depending on the level of an open container or a cistern.
Switching points: up ON / down OFF
FLOAT SWITCH WA 65 (PSN-O) 10M +VP

FLOAT SWITCH MS 1
Item no.: 2004593

Float switches for level control devices as min./max switches for fluids that are aggressive or contain faeces, floats with the fluid and switches when tilted. Because of its construction and switching point, the float switch can exhibit only a very small hysteresis. This property cannot be changed, not even the length of the cable. In order to use the float switch, a switchgear with adjustable run-on time must be used. Switching: up "ON"/down "OFF"
