For mines, water distribution and pressure boosting systems requiring enhanced motor protection, the Lowara Z855-04-3S combines a 304 stainless steel pump end with a 316 stainless steel motor housing. This 8-inch submersible electric pump uses four standard diameter impellers to deliver 1333 L/Min flow and 107.8 m head.
Semi-axial hydraulics with stainless steel impellers and diffusers manage fluid handling, while technopolymer wear rings and an AISI 431 shaft provide mechanical integrity. The 316 stainless steel motor offers enhanced corrosion protection for demanding applications. The unit handles sand content up to 100 g/m³ and temperatures up to 25°C.
An 18.5 kW L6W motor operates on a 415v three-phase supply at 38.5 Amps, with NEMA-standard coupling and flange dimensions. The motor is rated for immersion depths up to 350 metres and includes an integrated non-return valve.
