HPV70 Piston Type Agricultural Hydraulic Pumps In Machineries

Product Description

Highland HPV70 hydraulic piston pumps used in agricultural machineries

Highland HPV70 hydraulic pumps basic information: 

Highland Agricultural solutions with hydraulic pumps are used in practically every single hydraulic transmission system. Highland HPV70 hydraulic pumps are used in agricultural applications to produce high fluid pressure, which can connect additional pumps, gear pumps and same type piston pumps etc. For large machinery with continuous running hydraulic functions, Highland hydraulic piston pump is a standard choice. Highland agricultural hydraulic pumps are energy saving, high efficiency, easy to operate and reliable quality.

Highland Agricultural machineries hydraulic piston pumps main features:

Highland agricultural machineries hydraulic piston pumps are axial piston variable displacement pumps are well engineered and easy to handle. Bearings of variable displacement axial piston pumps are all tapered roller bearing, which can load heavy external axial forces. When hydraulic piston pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.

Highland HPV70 hydraulic piston pumps usage: 

Highland HPV70 hydraulic piston pumps plays an important role in agricultural machineryies mainly used in digging potatoes machine, combine harvesters, 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 machineries hydraulic piston pumps: 

Many hydraulic piston 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.
