The PAS range was developed as a result of our over 140 years’ experience working with construction customers across the world. Our strategy fits perfectly with pumps. The first focus, of course, is providing efficient products. We strive to develop products that are better for you and better for the environment. Secondly, the products should be easy to take to your point of work. Therefore we put a huge amount of focus on making products that are smaller and lighter, with features that make them easy to move. The PAS open frame pump systems consist of a highly efficient diaphragm pump with a semi-open impeller and a large separator. Air is separated from the liquid and sucked by the vacuum pump, making automatic and efficient priming possible. We offer both wet prime and dry prime options. Even with suction heights of multiple feet, 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.
