Product Description

High pressure Complete range pump water oil pto Gear Hydraulic Pump replacement of Agricultural flat tractor

Product Description

A gear hydraulic pump is a positive-displacement pump that converts mechanical energy (from the tractor's engine or PTO) into hydraulic power, generating fluid flow for:

• Implement control 

• Steering systems (hydrostatic steering)

• Brake assistance

• 3-point hitch operation

  Types of Gear Pumps for Tractors

  Type	Description	Advantages	Applications
  External Gear Pump	Two meshing gears in a housing	Simple, cost-effective, high pressure (up to 250 bar)	Loaders, log splitters
  Internal Gear Pump	Rotor + idler gear design	Quieter, handles viscous fluids	Older tractor models, low-speed applications
  Gerotor Pump	Inner/outer rotor system	Compact, smooth flow

Working Principle and Design Details
1.1 Basic Working Principle
Gear pumps operate on the positive displacement principle, where oil is trapped between the gear teeth and transported from the inlet to the outlet. In a tractor, this generates the hydraulic pressure required for the operation of the implement.

Oil Flow Process:

Suction Phase: Oil enters the cavity when the gears separate

Delivery Phase: Oil is transported between the gear teeth and the pump housing

Discharge Phase: The meshing gears discharge the oil under pressure

1.2 Precision Engineering Features
Tooth Profile:

Involute (most common) for smooth meshing

Modified cycloidal design for increased efficiency

Clearance Specifications:

Axial Clearance: 0.02-0.05 mm

Radial Clearance: 0.03-0.08 mm

Pressure Balance:

Lateral Wear Plates with Pressure Grooves

Hydraulic Force Compensation to Reduce Bearing Loads

Why Choose Gear Pumps for Tractors
Durability - More effective in handling contaminated fluids than piston pumps.
Cost-effective - Lower maintenance costs than vane/piston pumps.
Compact size - Fits into tight spaces in tractor hydraulic systems.
High RPM compatibility - Matches tractor engine speed (1,500-3,000 RPM).

Common Applications for Tractors
Front-end Loaders (Bucket Lift/Dump)
Backhoe Attachments (Digging/Rolling)
Hydraulic Suspension Systems (Lifting Plows/Sprayers)
Power Steering (Hydrostatic Power Steering)
Wood Splitter and Hay Baler (High Pressure Hydraulic)
