Product Description

High Quality Combine Harvester Hydraulic Piston Pump With Competitive Price

Combine Harvester Hydraulic Piston Pump introduction: 

Highland Agricultural hydraulic piston pumps are becoming more and more common in agricultural industry and daily life, because Highland hydraulic piston pump power could improve production efficiency, save labour and time, and bring more convenience to agricultural machines, such as combine harvesters, grass mower agricultrual machines. Our engineers are able to design and configure hydraulic pumps flexibly to meet the different needs of agricultural combine harvesters.

Highland Combine Harvester Hydraulic Piston Pump main features:

• Combine harvester hydraulc piston pumps are well engineered and easy to handle.
• Bearings of hydraulic axial piston pumps are all tapered roller bearing, which can load heavy external axial forces.
• HPV70 Hydraulic pumps can be connected with other additional pumps.
• When Hydraulic piston pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
• Upon release of the control handle, swash plate return to zero position automatically and the flow reduces to zero.
• Combine harvester hydraulic pumps has shaft oil seals performance, even at the lowest temperature and high case pressure.
• Servo valve of hydraulic piston pump can connect function regulators and remote control systems.
• Agricultural piston pumps can easy maintain and can be disassembled and assembled by standard tools. All components are replaceable.

Combine Harvester Hydraulic Piston Pump usage: 

Highland combine harvester hydraulic pumps are a new generation of hydraulic products. Compact size, flexibility and variable speed of hydraulic pumps are suitable for agricultural harvesters, meantime they provide power drives for harvesting functions, conveyors. With superior performance, safety and high efficiency.

Hydraulic oil notice of combine harvester hydraulic pumps: 

Hydraulic oil: The ability of hydraulic drives to maintain ideal performance and achieve life expectancy depends on the quality of the liquid operating in the unit. Liquid quality can be measured in three common categories: lubrication capacity, impurities, and temperature. Field experience shows that most drives fail due to the damaged surface of liquid quality, mainly solid particles impurities and overheating. Users of combine harvester hydraulic pumps should choose correct hydraulic oils and maintain promptly.
