The stainless steel shafts are fitted with carbon ceramic and NBR mechanical seals. Motors are continuously rated, have IP55 protection and incorporate an overload protection device. They are designed for pumping dirty water, with solids in suspension, at temperatures up to 90oC. The trash pump design incorporates a removable cover for clearing debris. Solids capacity: 22mm (1.5kW) and 32mm (2.2kW) 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.
