Fully submersible sewage pump for vertical wet well installation, for pumping sewage containing faeces, as well as municipal and industrial sewage. Unit made entirely of cast iron; on pump-side seal made of SiC/SiC, seal on the motor side is a rotary shaft seal or mechanical seal. Pressure connection with horizontal pressure port and flange connection. Surface-cooled motor in three-phase current version with thermal motor monitoring, sealing and leakage chamber and Ex rating. The leakage chamber is monitored using a float switch. As an option, the sealing chamber can be monitored by an external pencil electrode. Longitudinally watertight connection cable with bare cable end.
