4-inch Stainless Steel Submersible Pumps (50/60 Hz)
Our 4-inch stainless steel submersible pumps are perfect for agricultural, residential & industrial sectors. They are made with high-quality AISI-304 grade stainless steel and are designed as per the NEMA standards.
The 4″ stainless steel submersible pumps from Unnati Pumps are very effective since they have an energy-efficient hydraulic design, are easy to install, and also provide a cost-effective operation. The impellers and diffusers of this pump are built of stainless steel to maximize their efficiency, minimize loss, and achieve corrosion resistance.
The pump is protected from extreme water hammering by the built-in non-return valve. Moreover, there are strainers built into the input to refrain large particles from getting into the pump. High-grade rubber, such as NBR, is used in the construction of the intermediate bush and wearing ring.
The pumps are examined at each stage for quality assurance, and their flow, pressure, power consumption, and leaks are measured. This 4-inch stainless steel submersible pump can be used for irrigation, sprinklers, fountains, residential water supply, and more.
