The main components are fabricated in cast iron GG20. In the standard configuration a lip seal in oil chamber, is fitted to the motor side, and a mechanical seal to the impeller side. The G2 poles Series have an inbuilt macerator in the inlet. This breaks down solids in waste water which permits transport along relatively narrow, often pre-existing, pipes. Applications: domestic sewage, liquids with suspended solids, whenever high pressure (Hm) is needed. The pump has a macerator in the inlet with axial cutting action. The blades are made of hardened steel guaranteeing maximal cutting efficiency. Maximum 40°C liquid temperature. Maximum immersion 20 metres. Complete with 10 metres of power cable. The pumps with EX (ATEX) can be used in potentially explosive environments.
