Product Description
The PMP110 Gear Drive Hydraulic Charge Pump is a high-performance auxiliary pump designed to provide reliable charge pressure and continuous oil supply for closed-loop hydraulic systems. Featuring a robust gear-driven structure, it ensures stable operation, efficient oil circulation, and long service life even under demanding working conditions.
Low Noise & High Efficiency：Optimized gear design ensures smooth operation, low noise, and high volumetric efficiency.
Improve Main Pump Stability：Provides stable charge oil flow to maintain proper lubrication and cooling of the main pump.
Extend Hydraulic System Service Life：Reliable charge oil supply reduces wear and helps extend the lifespan of the hydraulic system.
Multiple Control Options：Compatible with different hydraulic control systems to meet various application requirements.
The PMP110 Gear Drive Hydraulic Charge Pump Circuit is a key subsystem in closed-loop hydrostatic transmission systems. It is designed to provide stable charge pressure, ensure continuous oil replenishment, and support cooling and filtration, thereby maintaining the efficiency and reliability of the entire hydraulic system.
In a typical hydraulic system, the PMP110 gear-driven charge pump circuit works alongside the main piston pump. It forms a complete auxiliary oil supply loop that ensures the system operates under stable pressure conditions.

Charge pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The PMP110 gear drive hydraulic charge pump provides a stable low-pressure oil supply to the closed-loop hydraulic system. It maintains charge pressure, compensates for internal leakage, and prevents cavitation in the main pump.
The PMP110 is a gear-type hydraulic pump that uses meshing gears to deliver a continuous and stable flow of hydraulic oil.
It is widely used in hydrostatic transmission systems such as excavators, loaders, road machinery, agricultural equipment, and industrial hydraulic systems.
Key advantages include simple structure, high reliability, stable performance, low maintenance requirements, and cost-effectiveness.
Typical symptoms include low charge pressure, abnormal noise, overheating, slow system response, and reduced machine efficiency.
Low pressure may be caused by worn gears, internal leakage, clogged filters, air entering the system, or a malfunctioning relief valve.
Maintenance includes using clean hydraulic oil, regularly replacing filters, checking seals and connections, monitoring oil levels, and inspecting internal components for wear.
Yes, it can be replaced with a high-quality aftermarket equivalent, as long as the specifications such as displacement, mounting dimensions, and pressure ratings are compatible.
Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
