1.1 Application
With the Jet-pump WlLO offers an inexpensive
water supply unit in the fields of home, hobby and
garden. The pumps are suitable for:
– watering and sprinkling from ponds, creeks and
bores,
– draining of tanks and containers,
– dewatering of flooded basements
.
The pump works self-priming (e.g. from bores) or
with flooded suction (e.g. from open tanks).
It must not be connected directly to public water
supply systems.

4. Description of Product and Accessories
All WJ-series pumps are self-priming. AlI parts
in contact with the medium being handled are of
corrosion-resistant steel. Single-phase motors
have built-in thermal contacts, switching off the
motor on overload and on again after a cooling
down period. A mechanical seal separates the
pump housing from the motor.
ATTENTION!
The pump must not run dry.
Warranty does not cover damages to the pu mp
due to dryrunning.
