Wilo-Extract FIRST SE

Intelligent rainwater utilisation for domestic garden and household water supply.

The Wilo-Extract FIRST is a multistage submersible pump. It is used for the reliable extraction of rainwater from rainwater storage tanks or reservoirs in single and two-family houses. The rainwater can be used for domestic water supply for toilets, washing machines or even for watering the garden. The compact design of the flexible pump allows for use in reservoirs with cramped access. The integrated control unit enables easy installation without accessories and a quick start. Integrated protective functions such as dry-running detection ensure a high level of operational reliability. The corrosion-resistant materials are highly reliable.

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.
