Wilo-Rexa MINI3

Wilo-Rexa MINI3 - Submersible sewage pump for intermittent operation

Overview

High efficiency and high operational reliability due to optimized hydraulics
Easy installation even in narrow drainage pits due to compact design with integrated condenser, low weight and threaded flange
Reliable drainage in various applications thanks to its corrosion resistant impeller and sealed cable gland
Extended service intervals due to large seal chamber and double sealing
Quick maintenance with direct access to seal chamber and pump casing

Fail-safe pump for pumping wastewater and sewage from domestic sewage and land drainage.

The Wilo-Rexa MINI3 is the ideal standard submersible pump for pumping wastewater from domestic sewage systems and land drainage. With its 40 mm free ball passage, it is especially suitable for conveying dirty water and sewage that does not contain faeces. The pump is designed for stationary or mobile submersible installation. If the pump is installed in a pump sump, the DrainLift WS 50 can handle sewage containing faeces, because the system is then approved to EN 12050-1. The optimized hydraulics ensure high reliability for universal use in the most varied operating environments. The compact design also makes installation in narrow drainage pits possible. Oil-filled seal chamber and double seals allow extended maintenance intervals. Direct access to critical components for maximum ease of maintenance.

Type

Description/construction

Submersible sewage pump with electric motor as submersible monobloc unit, suitable for mobile wet well installation in intermittent operation.

Hydraulic

Pump with free-flow impeller and clearance for spherical particles of 40 mm. Pressure connection as vertical threaded connection.

Electrical motor

Surface-cooled electric motor in single-phase version (with built-in operating capacitor) or three-phase version for direct starting. The heat is given off directly to the environment via the motor housing. These electric motors can be used in immersed state in continuous operation (S1), and in non-immersed state – in repeated-short-time operation (S3).

The motor is equipped with an automatic motor winding temperature monitoring sensor. This means that if the motor overheats, it shuts off and automatically restarts after cooling down.

The electric motor is equipped with an automatic motor winding temperature sensor.

The power supply cable is either 5 m or 10 m in length and is available in the following versions:

  • With loose cable ends
  • With plug
  • With float switch and plug

Sealing

Fluid side — sliding mechanical seal, electric motor side — lip seal on shaft. Between the seals is a sealing chamber filled with white oil.
