Construction

Single-phase version

The sewage pump is equipped with a vortex impeller or a half-open single-channel impeller. The pump has a horizontal discharge port with a flange connection. The hydraulics housing and the impeller are made of cast iron. The surface-cooled single-phase motor has winding temperature monitoring and an internal moisture probe for leakage detection. The oil-filled sealing chamber has two mechanical seals. The motor housing is also made of grey cast iron. The pump is supplied with a detachable connection cable that has a capacitor box for the starting and operating capacitors as well as bare cable ends. The pump is Ex-certified as standard.

Three-phase version

The sewage pump is equipped with a vortex impeller or a half-open single-channel impeller. The pump has a horizontal discharge port with a flange connection. The hydraulics housing and the impeller are made of cast iron. The surface-cooled three-phase motor has winding temperature monitoring and an internal moisture probe for leakage detection. The oil-filled sealing chamber has two mechanical seals. The motor housing is also made of grey cast iron. The pump is supplied with a detachable connection cable with bare cable ends. The pump is Ex-certified as standard.
