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 feet the machine rapidly evacuates the air
from the suction pipe and starts to pump. Additionally, thanks to the semi-open impeller,
the PAC range is also suitable for pumping liquids with solids in suspension with best
possible efficiency.

delivers best in class pumping efficiency. One of the most common area of utilization is
the mining and Oil & Gas segment where reliability, efficiency and versatility is the key
to provide a customized solution. Other suitable applications within Construction and
General dewatering, Municipal as well as General Industry are ideal for the PAC H43C
pump. Atlas Copco pumps are packed with features that not only meet, but exceed the
needs of our customers.
