- Gas separation
One special advantage lies in their one-piece variable-pitch rotors. They provide the internal compression that is necessary for reducing energy costs in HeptaDry pumps. It also enables thermally sensitive gases to be pumped. The dynamic wear-free seal between the bearing and the pump chamber increases operational reliability. The pump’s innovative design and low speed result in minimal stress on the bearings and seals.
