The Grundfos jet pumps, type JP, are horizontal,
self-priming centrifugal pumps designed for pumping
water and other thin, non-aggressive and
non-explosive liquids, not containing solid particles
or fibres.
If the pump has been used for dirty liquids, e.g. pool
water, flush it through with clean water immediately
after use.
Warning
Do not use the pump for flammable liquids,
such as diesel oil and petrol.
Warning
Do not use the pump for aggressive
liquids, such as acids and seawater.
