Sprayer Agricultural Hydraulic Pump Through Shaft Plunger Pump

Product Description

 Highland Weeding machine agricultural hydraulic pumps easy to maintain

Highland Weeding machine agricultural hydraulic pumps basic introduction: 

Highland Hydraulic pumps are typical volumetric fluid pumps, driven by the prime mover, converting the input mechanical energy into the pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow.Hydraulic pumps are the power source of the hydraulic system. Because hydraulic pumps can transport liquids under high pressure, they are widely used in in agricultural machinery and daily life, such as weeding machines.

Highland Agricultural hydraulic pumps main features:

• Axial piston variable displacement pumps are well engineered and easy to handle.
• Bearings of variable axial piston pumps are all tapered roller bearing, which can load heavy external axial forces.
• When hydraulic pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
• Hydraulic pumps has shaft oil seals performance, even at the lowest temperature and high case pressure.
• Servo valve of piston pump can connect function regulators and remote control systems.
• Axial piston pumps can easy maintain and can be disassembled and assembled by standard tools. All components are replaceable.

Highland Agricultural hydraulic pumps usage: 

Highland Agricultural hydraulic pumps plays an important role in agricultural machinery, mainly used in combine harvesters, weeding machines, crop harvesters, planters, mowers and tractors etc many farming equipments for its safety, energy efficiency, ease of operation, and reliability.

Hydraulic oil notice of Highland agricultural pumps: 

Hydraulic oil is very important for hydraulic pumps, many hydraulic pumps cannot running well, which are related to fluid contamination, why?

Because of incorrect oil type, viscosity, additives, small and large size solid particles. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
