Simple and reliable 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 tanks in detached and semi-detached 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 tanks with cramped access. Easy to install without accessories and can be started quickly because of the integrated control unit. Integrated protective functions such as dry-running detection ensure high operational reliability. Corrosion-resistant materials offer high reliability.

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.
