GR Series Positive Displacement Stainless Steel Single Screw Pump

The GR series stainless steel single screw pump is a progressive cavity positive displacement pump designed for stable and precise fluid transfer. Manufactured with high-grade SUS304 or SUS316L stainless steel, it ensures excellent corrosion resistance and hygienic performance, making it especially suitable for industries with strict sanitary standards.

This single screw structure enables uniform, low-pulsation conveying, which is ideal for sensitive media. It performs exceptionally well when handling high-viscosity fluids, shear-sensitive materials, and media containing fibers or soft solids. The pump maintains a consistent flow rate regardless of pressure fluctuations, ensuring process stability.

With strong self-priming capability and the ability to operate under vacuum conditions, the GR single screw pump supports continuous, long-duration operation without flow interruption. Its compact structure, smooth operation, and low noise make it a preferred solution for precision fluid handling.

Typical Applications:
Widely used in food processing, pharmaceuticals, cosmetics, and fine chemicals, it is ideal for transporting materials such as sauces, syrups, dairy products, pharmaceutical liquids, and emulsions where gentle handling and stable flow are critical.
