Construction

Rainwater storage tank pump in block design with radial impellers as multi-stage hydraulics.

Single-phase AC motor with sheath flow cooling. The motor is cooled by the pumped medium. A self-switching thermal motor protection is installed to protect the motor.

The motor itself is dry. Sealing is provided on the motor and medium side by two mechanical seals. Between both mechanical seals is an oil barrier chamber. The oil barrier chamber is filled with white oil and absorbs any leakage through the medium-side seal.

Robust connection cable of type H07RN-F with attached plug. The connection cable is resistant to UV, ozone and oil.
