The core advantages of melt gear pumps are primarily reflected in four areas: stable pressure and improved product quality, increased output and energy efficiency, linear controllability, and durability and long service life. As a professional manufacturer of gear metering pumps, Tianjin Ruicheng Pump Industry Co., Ltd. has been deeply involved in this field for many years, and its products play a critical role in the polymer extrusion and petrochemical industries.
Stabilize and enhance quality to improve product precision
The most notable function of a melt gear pump is to isolate upstream fluctuations. Issues such as speed pulsations, temperature fluctuations, and uneven feeding in an extruder are difficult to completely eliminate. By utilizing the positive displacement principle, the melt pump effectively attenuates inlet pressure fluctuations, maintaining highly stable outlet pressure. This characteristic directly minimizes product dimensional tolerances and effectively reduces scrap rates, making it particularly suitable for applications with stringent uniformity requirements, such as film production, synthetic fibers, and pressure boosting for petrochemical pipelines.
Increase production and energy efficiency, and reduce production costs
After installing a melt gear pump, the pressure-building function is transferred from the extruder to the pump. Backpressure on the extruder can be significantly reduced, allowing the screw to operate at high speeds and with high efficiency under low-pressure and low-temperature conditions. This reduces the load on the extruder and achieves energy savings. This results in significant benefits: output can increase by more than 20%, energy consumption per kilogram of material is significantly reduced, and wear on the screw and barrel is minimized, thereby extending the service life of the entire machine.

Increase production and energy efficiency, and reduce production costs
The flow rate of a melt gear pump is strictly linear with respect to speed, allowing for precise control of the output volume per unit time through variable-frequency speed regulation. Ruicheng Pump Industry also offers closed-loop pressure control technology, which uses online monitoring and automatic adjustment to maintain precise and stable melt pressure, with adjustments completed within milliseconds.
Withstands high temperatures and pressures, suitable for harsh operating conditions such as those found in the petrochemical industryMelt gear pumps are widely used in the petrochemical industry. Tianjin Ruicheng Pump Industry’s products are manufactured from high-performance materials such as high-strength alloy steel, tool steel, and corrosion-resistant alloys. The pumps feature short, smooth internal flow channels specifically designed for materials prone to polymerization—such as polyester, nylon, and polyurethane—effectively preventing material stagnation and decomposition. Their reactor bottom pumps solve the challenge of discharging high-viscosity, polymerizable materials from reactors and can be used for the reaction transfer of high-viscosity materials and pipeline pressurization in various petroleum and chemical processes.
As a professional manufacturer of gear metering pumps that integrates R&D, production, and sales, Tianjin Ruicheng Pump Industry Co., Ltd. produces melt pumps that serve as the “precision heart” of production lines. These pumps ensure stability by isolating fluctuations, achieve energy savings and high productivity by reducing back pressure, enable precise metering through their linear characteristics, and guarantee long-term reliable operation thanks to their robust and durable design. As a result, they have become a core component for enhancing quality, reducing energy consumption, and strengthening competitiveness in industries such as petroleum, chemicals, and synthetic fibers.
