4" Stainless Steel Submersible Pumps (50/60 Hz)

Build Quality & Material

Marwaan’s 4-inch submersible pumps are crafted from premium AISI-304 grade stainless steel, offering excellent corrosion resistance and mechanical strength. Built in compliance with NEMA standards, every component—from the outer body to the impellers and diffusers—is engineered for durability and long-term efficiency in challenging conditions.

Hydraulic Design & Efficiency

These pumps feature an energy-efficient hydraulic design that ensures minimal power consumption while delivering optimal water flow. The stainless-steel impellers and diffusers are built to enhance performance and reduce hydraulic losses, making the system cost-effective for continuous use across various sectors.

Operational Safety & Longevity

To protect against damage, the pump includes a built-in non-return valve that mitigates water hammering. An integrated suction strainer prevents debris from entering the pump, while NBR-grade rubber parts—used in the wearing ring and intermediate bush—enhance abrasion resistance and operational stability.

Applications & Testing

Every Marwaan pump is rigorously tested for pressure, flow rate, leak integrity, and energy consumption at every stage of production. The 4-inch model is versatile, ideal for irrigation, sprinkler systems, fountains, residential water supply, and light industrial use—ensuring dependable service across multiple environments.
