GR Series Stainless Steel Two-Stage Self-Priming Screw Pump

The GR series stainless steel two-stage screw pump is a high-efficiency positive displacement pump engineered for demanding transfer conditions requiring enhanced suction and pressure performance. Built with SUS304 or SUS316L stainless steel, it delivers superior durability, corrosion resistance, and adaptability to complex industrial environments.

Featuring a two-stage screw design, this pump significantly improves self-priming performance and lifting capacity, making it especially suitable for applications involving long-distance transfer, high suction lift, or intermittent fluid supply. It can efficiently handle liquids containing gas, foam-prone media, abrasive particles, and mixed-phase fluids.

Compared with single screw pumps, the two-stage structure provides stronger conveying force and higher operational efficiency, ensuring stable flow even under fluctuating working conditions. It is capable of continuous operation with minimal vibration and reliable sealing performance.

Typical Applications:
Ideal for petroleum, chemical processing, wastewater treatment, marine engineering, and industrial slurry transport, it is commonly used for transferring oil, sludge, chemical slurries, corrosive liquids, and industrial waste fluids where robust suction and conveying power are required.
