4" 50 Hz Stainless Steel Submersible Pumps

4SK2 Series Stainless Steel Submersible Pumps (60 Hz)

The pump’s core components are crafted from stainless steel and copper alloy, offering superior performance and durability. This design ensures high efficiency, energy conservation, excellent wear resistance, and corrosion protection. The pump boasts an attractive appearance and is simple to install. It’s versatile enough for various applications, including residential, commercial, and industrial use. Common applications include water supply systems, irrigation, wash-down operations, and pressure-boosting setups.


    • Superior Construction: The pump features a robust build with a thick stainless steel 304 pump tube (1.5mm), complemented by a stainless steel 304 diffuser and a pump head made of either 304 or 316 grade stainless steel. This premium material selection ensures high strength, corrosion resistance, and an aesthetically pleasing appearance, all contributing to the pump’s durability and longevity.
    • Advanced Impeller Technology: At its core, the pump utilizes a multi-stage floating impeller design. This innovative feature significantly reduces the starting torque requirements, enabling smoother and more efficient operation. Additionally, it provides superior resistance to blockages from small sand particles, demonstrating a strong ability to handle sandy environments. As a result, the motor experiences less stress, leading to an extended service life and improved overall performance.
