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

Hydraulics

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.

Motor

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:

Seal

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.

Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation in intermittent operation.

Hydraulics

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

Motor

The motors available are surface-cooled motors in single-phase version (with built-in operating capacitor) and three-phase version for the direct starting. 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 periodic duty (S3).

Furthermore the motors are equipped with thermal motor monitoring. This protects the motor windings against overheating. For units with single-phase AC motors this is built-in and switches automatically. I.e. if the motor is switched off due to overheating and then cools down it is automatically switched on again. Bimetallic strips are used for this as standard.

In addition the motor can be equipped with an external sealing chamber electrode for monitoring the oil barrier chamber. This signals if there is water ingress into the oil barrier chamber through the mechanical seal on the fluid side.

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

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

Seal

There is a sealing chamber between the motor and hydraulics. This 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.

Submersible sewage pump with internal or external macerator as submersible monobloc unit for stationary and portable wet well installation in intermittent and continuous duty.

Hydraulics

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.

Motor

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 periodic duty (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 moisture probe 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.

Seal

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.
