Description/design

Submersible sewage pump with internal or external macerator as submersible monobloc unit for stationary and portable wet well installation in intermittent and continuous duty.The outlet on the pressure side is designed as horizontal flange connection with a DN 32/40 combined connection. The maximum possible dry matter is 8 % (depending on the hydraulics) Single-channel and multi-channel impellers are used.Single-phase and three-phase current surface-cooled motors for direct starting are used as the motors. 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 operation (S3).The motors are equipped with a thermal winding monitor. This protects the motor windings against overheating. Bimetallic strips are used for this as standard. Motors in the P-version are also equipped with motor compartment monitoring. The humidity electrode signals water ingress into the motor compartment.Furthermore, the motor can also be fitted with an external pencil electrode to monitor the sealing chamber. This signals if there is water ingress into the sealing chamber through the seal on the pump side.The connection cable has a length of 10 m as standard and the single-phase version is equipped with a plug. The three-phase version has bare cable ends as standard and is cast as longitudinally watertight for P-version motors.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. The pump-side and motor-side seals are provided by two mechanical seals which rotate independently of each other.
