Z6, ZN6 – Submersible pumps for 6” wells

Category Brand


The Z6 and ZN6 submersible pumps for 6” wells are sturdy and lightweight pumps very easy to maintain, thanks to the modular design and its high sand handling capability (100 g/m3). The Z6 pump is made in AISI 304, the ZN6 version in AISI 316. Head and motor support are made in precision cast stainless steel, with stainless steel impellers and diffusers. Tungsten Carbide shaft bearings and stainless steel. shaft sleeves ensure long lasting reliability and efficiency.
