Pump wheel

Product Introduction

The pump impeller is the core active power component inside the hydraulic torque converter. Working in conjunction with the turbine and guide wheel, it serves as the “power input end” of the torque converter. Driven by the engine, it rotates, converting mechanical energy into the kinetic energy of hydraulic oil. Power is transmitted through the impact of high-pressure oil against the turbine blades, making it a crucial component for power conversion in the hydraulic transmission system.

Made of high-strength precision cast aluminum alloy, the blades are streamlined and precision-designed using CNC machining. The entire unit undergoes high-precision dynamic balancing and surface strengthening treatment. It boasts high rigidity and toughness, resisting deformation and cracking, cavitation resistance, and high oil temperature resistance. It ensures smooth hydraulic oil flow and high power conversion efficiency. Dimensions and assembly positions fully conform to original equipment manufacturer (OEM) standards, ensuring high interchangeability. It can directly replace the original pump impeller and is suitable for repairing and installing hydraulic torque converters in various loaders.

Application Scenarios

• Construction sites: Earthmoving, site leveling, frequent starts, and low-speed heavy-load operations. The pump impeller’s efficient power conversion drives the hydraulic oil to smoothly impact the turbine, achieving smooth starting and strong power output for the entire machine.
• In mining and quarrying environments: Under heavy-load, uphill, and high-impact conditions, the high-speed rotation of the pump impeller generates high-pressure oil, which, in conjunction with the turbine and guide wheel, achieves automatic torque increase. It can withstand high torque without easily being damaged, ensuring continuous power transmission.
• In sand and gravel yards, coal yards, and mixing plants: For long-term, continuous, high-frequency operation, the pump impeller operates stably, withstands high loads, has a slow temperature rise, and is less prone to cavitation and blade cracking, ensuring long-term, efficient operation of the torque converter.
• For complete machine maintenance and overhaul: Suitable for replacing worn, cracked, or deformed pump impellers in the torque converters of 3-ton, 5-ton, 6-ton, and 7-ton wheel loaders, eliminating the need to replace the entire torque converter assembly and reducing maintenance costs.
• In harsh working environments: Adaptable to dusty, high-oil-temperature, and high-frequency vibration conditions in the field, it is resistant to hydraulic oil corrosion and aging, and the blades are not easily worn, effectively extending the overall service life of the torque converter.
