The Speroni HG100 Pumps are self priming, mono-block, centrifugal pumps with pump bodies, motor supports and open impellers in cast iron. The design incorporates a rubber check valve, to maintain the priming water level, and enable automatic priming during starting, even when the inlet pipe is empty. The stainless steel shafts are fitted with carbon ceramic and NBR mechanical seals. Motors are continuously rated and have IP55 protection. They are designed for pumping dirty water, without abrasive particles at temperatures up to 90°C. They are capable of a suction lift of 7 metres. They are designed for many industrial and agricultural applications where large volumes of water need to be pumped.
