The pump system consists of a centrifugal pump and a separator, which enables air to be
separated from the liquid and be sucked by a vacuum pump - making automatic priming
possible. Even with suction heights of several meters the machine rapidly evacuates
the air from the suction pipe and starts to pump. Additionally, thanks to the semi-open
impeller, the PAS HF range is also suitable for pumping liquids with solids in suspension.
Both Atlas Copco and Varisco have decades of experience in designing and producing
pumps. We have put those years of expertize into providing a solutions portfolio that
works across multiple applications. The PAS HF (high flow) range is packed with features
that not only meet, but exceed the needs of the market. We are focused on an efficient,
extremely versatile pump that is suitable for many industries, including construction,
general dewatering and emergency applications, such as flood clean up.
