Difference Between Screw Pump and Gear Pump: A Comprehensive Comparison for Manufacturers

Tianjin Shuangjin Pumps & Machinery Co., Ltd. is a leading manufacturer and factory of pump products in China. When looking for high-quality pumps, you may come across two popular types: screw pumps and gear pumps. Although they may look similar, there are fundamental differences between these two pumping mechanisms.

Screw pumps use helical rotors, which create a continuous seal across the length of the screw. They are known for their ability to handle high viscous fluids and can operate at a steady flow rate, making them ideal for heavy-duty applications. On the other hand, gear pumps work by meshing gears to create a vacuum at the inlet and discharge pressure at the outlet. They are ideal for low to medium viscous fluids, with varying flow rates depending on the size of the gears.

Depending on your specific application, either a screw pump or a gear pump from Tianjin Shuangjin Pumps & Machinery Co., Ltd. may be the best choice for you. Contact us to learn more about our top-of-the-line pump products and find the right solution for your industry.
