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.
