Royal Max submersible pumps come in three types; the stainless steel, plastic and cast iron. All these submersible pumps are multistage single suction centrifugal type provided with integral check-valve and NEMA standard coupling. These pumps are available with fabricated impellers and diffusers made of AISI 304 and the shaft is made of AISI 304/431.
The integral check valve prevents back flow and reduces the risk of water hammer which paves the way for trouble free performance. The suction screen is designed with utmost care so as not to reduce the inflow of water and at the same time to prevent damage to the pump and clogging due to the entry of sand and other foreign particles.
