6" & 8" Evergreen Submersible Pumps


C.R.I. 6" & 8" Evergreen series submersible pumps are available with different material of construction. Pumps are incorporated with externally hardwearing bearing and built in Stainless Steel Check valve. All vital components of these pumps are designed for the best possible hydraulic efficiency. All the bronze components are made of zinc free bronze to resist corrosion and to withstand wear and tear caused by sand. The Shaft made of SS 431 ensures the long life of the pump. Pumps are multistage centrifugal type, which are firmly coupled to submersible electric motor which operates submerged beneath the surface of water. Built in check valve prevents the back flow and reduces the risk of water hammering. All mounting dimension of pump are accordance with NEMA standard.
