Abstract

The device has a housing with a peripheral wall and a front wall for connection to the pump and a pressure sensor exposed to waste water for switching the motor on and off arranged in a space in the motor housing. An inlet channel open to the surroundings between the peripheral wall and an opposing front wall surface is connected to a channel leading through the front wall to the space bounding on this end wall and to the pressure sensor. The device has a housing with a peripheral wall and a front wall (5) for connection to the pump and an associated pressure sensor (10) exposed to the waste water for switching the motor on and off. The pressure sensor is arranged in a space (6) in the motor housing (3). An inlet channel (11) open to the surroundings between the peripheral wall and an opposing surface of the front wall is connected to a channel (12) leading through the front wall to the space bounding on this end wall and to the pressure sensor.
