HPV70 Agricultural Hydraulic Pumps Maize Harvesting Mechanization Piston Pump

Product Description

Maize harvesting mechanization agricultural hydraulic pumps high quality

Maize harvesting hydraulic pumps introduction: 

Agricultural harvester hydraulic pumps are used in practically every single hydraulic transmission system. Our 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, a variable displacement piston pump is a standard choice. Our agricultural harvester hydraulic pumps are energy saving, high efficiency, easy to operate and reliable quality.

Maize harvester hydraulic pumps main features:

1. Agricultural hydraulic pumps can connect gear pumps, piston pumps, double hydraulic pumps, triple or quadruple pumps. 

2. We have R&D team, and can design and custom make hydraulic pumps according to customers request. 

3. We can help customer design hydraulic system, solve hydraulic confusion. 

Agricultural hydraulic pumps usage: 

Agricultural hydraulic pumps plays an important role in agricultural machinery, 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 agricultural pumps: 

• The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
• Hydraulic oil:
• Generally speaking, the replacement time of hydraulic oil of sealed oil tank system is 2000hours. If the hydraulic oil is contaminated or other outside material bears abnormal running condition, the hydraulic oil should be changed often.
• Hydraulic oil in the open oil tank system should be changed every 500hours. For different vehicle, the measures should determined by specific design and operational experience.

Company service: 

• Lightning supply
• Regular single product Supply for immediate delivery, batch can be quickly shipped according to customer demand.
• Commitment to warranty hydraulic pump and hydraulic motor within one year.
• Provide personalized and customized services according to customer needs.

Factory Performance Testing

Each agricultural hydraulic pump in the HPV70 series is supported by a documented closed-loop hydraulic pump performance test record.

The supplied factory report identifies the unit as HPV70-MA-R-21, rated at 70 mL/rev, and records a test performed on September 14, 2026 at 26.8°C.

Documented values include operating speed, pressure, flow, displacement, torque, input power, output power, overall efficiency and volumetric efficiency, across pressure points from approximately 5 MPa to 30.6 MPa.
