Upgrade your hydraulic system with a pump designed to restore the factory specification performance of CAT 3116, C7, and 3126 series engines. Whether you are engaged in construction, mining, or agricultural operations, this pump can meet the flow consistency and pressure stability required by your equipment.
Main features and advantages
Bolt fixing accessories: manufactured according to precise OEM dimensions, can achieve seamless installation - no need for mechanical processing or adapters.
High quality structure: The lightweight aluminum shell is corrosion-resistant, while the hardened alloy gear can withstand high pressure and wear.
Consistent flow performance: The precision ground gear profile can maintain stable oil delivery from idle to maximum speed range, thereby reducing cavitation and noise.
Durability testing: Each pump undergoes long-term pressure cycling bench testing to ensure leak free operation and extended service life.
Ideal application
Very suitable for hydraulic steering circuits, transmission lubrication, and auxiliary systems of off-road machinery in harsh environments.
Installation and maintenance skills
Preparation: Drain the system oil and remove the old pump; Clean the mating surface.
Installation: Install new seals, align with the pump, and torque the installation bolts to 25 N · m.
Debugging: Re inject the recommended hydraulic oil, exhaust the air in the pipeline, and perform low-speed running in.
Maintenance: Check the seals every 500 hours and monitor the pressure to detect early signs of wear.
