Construction
Rainwater storage tank pump in monobloc design with radial impeller as multistage hydraulics.
Single-phase current motor with sheath flow cooling. The motor is cooled by the pumped fluid. The motor is equipped with automatic thermal motor monitoring.
The motor itself is dry. Two mechanical seals are used to seal the motor and the fluid. There is an oil separation chamber between the two mechanical seals. The oil separation chamber is filled with white oil and absorbs leakage through the seal on the fluid side.
Connection cable with fitted plug.
