Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation, as well as stationary dry well installation.


The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter is 8 % (depending on the hydraulics). Vortex and single-channel impellers are used.


The motor versions used are single-phase current and three-phase current surface-cooled motors. For single-phase current motors, the condenser is installed in a separate switchgear. Depending on performance, activation is carried out via direct startup or star/delta startup.

The motor is cooled by the medium around it (pumped fluid or air). The waste heat is dissipated via the motor housing.

The motors can be immersed during continuous duty (S1). In submerged operation, the operating modes S1 (continuous duty), S2 (short-time duty) or S3 (intermittent) are possible depending on the rated motor power.

Furthermore the motors are equipped with the following monitoring devices:

  • Leakage detection motor compartment: The leakage detection signals water ingress into the motor compartment.
  • Thermal motor monitoring: thermal motor monitoring protects the motor winding against overheating. Bimetallic strips are used for this as standard.

The motor can also be fitted with an external sealing chamber electrode to monitor the sealing chamber. This signals if there is water ingress into the sealing chamber through the mechanical seal on the fluid side.

The connection cable has bare cable ends and a length of 10 m as standard, and is available in following versions:


Located between the motor and hydraulics is a sealing chamber with the seal on the fluid and motor side. This sealing chamber is filled with medicinal white oil. The fluid-side and motor-side seals are provided by two mechanical seals which rotate independently of each other.
