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. Self-switching thermal motor protection is installed to protect the motor.
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.
Robust connection cable of type H07RN-F with attached plug. The connection cable is resistant to UV, ozone and oil.
