Aluminum Gear Pump Bodies for Compact Hydraulic Systems

Product Highlights

• Compatible with Common Pump Groups
  Available for Group 0, Group 1, Group 2 and Group 3 gear pumps, with standard mounting patterns and port layouts that fit most international brands.

• High-Strength Aluminum Alloy
  Lightweight housings with high mechanical strength, ideal for mobile equipment and industrial machinery where weight and efficiency are critical.

• Precision CNC Machining
  Tight tolerances on bore diameter, concentricity and surface finish ensure smooth rotation, reduced leakage and lower noise of the assembled pump.

• Corrosion-Resistant Surface Treatment
  Optional anodizing and other coatings improve wear and corrosion resistance, extending service life in demanding environments.

• Flexible Design Options
  Different shaft ends, mounting flanges, inlet/outlet port positions and thread types can be specified to match your hydraulic layout and installation space.

• OEM & ODM Service
  We can produce according to your 2D / 3D drawings, samples or designated pump brands, and support prototype orders before mass production.

Typical Technical Specifications

(You can adjust the data below to your real specs.)

Note: The above values are typical ranges. We design and manufacture housings according to your required displacement, pressure rating and mounting dimensions.

Customization & Engineering Support

We know that many hydraulic projects require more than a standard housing. Our engineering team can:

• Match your existing gear pump brand and model based on samples or drawings.

• Adjust bore size, wall thickness and port positions for special working pressures or installation spaces.

• Recommend suitable aluminum grades and surface treatments according to your working medium and environment.

• Provide 2D/3D drawings for approval before tooling and mass production.

This helps you shorten development time and keep your pumping solution fully under control.

Typical Applications

Our aluminum gear pump bodies are widely used in:

• Mini hydraulic power units and compact power packs

• Lift tables, scissor lifts and material handling equipment

• Agricultural machinery and small construction machines

• Lubrication and cooling systems for industrial equipment

• Power steering and auxiliary hydraulic circuits for vehicles

• Other compact hydraulic gear pump assemblies

If your application requires a light, efficient and durable gear pump, these housings are an ideal starting point.

Manufacturing & Quality Control

To ensure consistent quality, we operate a controlled manufacturing process:

• CNC machining centers dedicated to hydraulic components

• Inspection of critical dimensions (bore size, parallelism, surface roughness)

• 100% visual inspection for casting / machining defects

• Optional pressure and leakage testing on assembled pumps in cooperation with your requirements

• Traceable production batches for long-term projects

With this process, you receive pump bodies that assemble smoothly, reduce rework and improve your final pump performance.

FAQ

Q1: Can you make housings compatible with my existing gear pump brand?
Yes. If you provide samples or full drawings, we can produce housings that match your current pump dimensions and interfaces.

Q2: What is the typical lead time for prototypes and mass production?
Prototype housings usually take about X–Y weeks after drawing confirmation. Mass production lead time depends on quantity and complexity; we will confirm a clear schedule with you before order.

Q3: Do you also supply complete gear pumps, not only housings?
We can cooperate with you in different ways. Please let us know if you need complete assembled pumps, and we will discuss the best solution according to your project.
