The PAS open frame pump systems consist of a centrifugal pump with a semi-open impeller and a large separator. Air is separated from the liquid and sucked by the vacuum pump, making automatic priming possible.
Wet prime pumps offer an extremely portable, cost effective solution. They are best suited to applications with a consistent flow. Dry prime pumps offer improved efficiency over longer periods of usage. They are best suited for applications where you might experience periods of running dry or intermittent flows.
Even with suction heights of several metres, both ranges rapidly evacuate the air from the suction pipe and start to pump. The semi-open impeller makes both ranges suitable for pumping liquids with solids in the suspension.
