In conclusion, gear pumps are a cornerstone of industrial fluid transfer, valued for their precise, pulse-free flow, handling capability of viscous media, and robust design. Shanghai Gaotian Pump Manufacturing Co., Ltd. leverages these inherent advantages through superior engineering, material science, and a deep understanding of diverse industrial needs. By providing reliable, durable, and application-specific gear pump solutions, Gaotian plays a vital role in ensuring the smooth and efficient operation of countless processes across manufacturing, energy, chemical, and agricultural industries worldwide.

Two main architectures are used: external gear pumps (two identical gears on parallel shafts) and internal gear pumps (a smaller rotor inside a larger ring gear with a crescent partition). External gear designs are compact and widely used in hydraulic systems, while internal gear units offer superior suction capability and better tolerance for high viscosity fluids; they are often selected for filling and emptying duties and can provide bi‑directional flow. For very high viscosities, internal gear pumps are typically the first choice.
