8’’ Stainless Steel Submersible Pumps (50/60 Hz)
For the most demanding applications, such as potable water supply from deep wells, firefighting systems, municipal water supply, pressure building in high-rise buildings, etc., the 8- inches stainless steel pumps from Unnati Pumps are manufactured to the highest standards.
Our 8″ submersible pumps are appropriate for corrosion and abrasion prevention, energy efficiency, high performance, rugged construction, and long service life, thanks to their fabricated AISI-304 stainless-steel body. The best possible hydraulic efficiency is aided by the ideal design of impellers and diffusers.
Additionally, they are extremely strong and can withstand strong upload thrusts. To ensure trouble-free service, these submersible stainless-steel pumps are particularly manufactured with the highest care and strict quality control at every stage.
