High-Volume Continuous Rotary Gear Oil Pump

When your application requires a massive, continuous flow of oil rather than intermittent, precise drops, the High-Volume Continuous Rotary Gear Oil Pump is the workhorse you need. Utilizing two intermeshing gears to displace fluid, this pump delivers a smooth, pulse-free stream of oil. It is highly effective for circulating oil through large industrial gearboxes, maintaining hydrostatic bearings, or feeding complex hydraulic cooling loops.

Key Advantages & Benefits:

  • High Flow Rates: Capable of moving dozens of liters of oil per minute continuously.
  • Pulse-Free Delivery: The rotary gear design ensures a smooth, constant pressure without the spiking associated with piston pumps.
  • Durable Design: Built with hardened steel gears to withstand continuous 24/7 industrial operation.
  • Self-Priming: Excellent suction capabilities allow the pump to draw oil from deep reservoirs.

Versatile Applications:

  • Circulation lubrication for large industrial gear reducers
  • Hydrostatic guideways on massive boring mills
  • Oil cooling and filtration loops
  • Marine engine lubrication systems

Frequently Asked Questions (FAQ):

  • Q: Can this pump be used with volumetric (PDI) injectors? A: Usually not out of the box. Gear pumps provide continuous flow. To use them with PDI injectors, you must install a separate, timed pressure-relief valve in the main line.
  • Q: What viscosity of oil can it handle? A: Gear pumps are excellent at handling thicker lubricating oils and heavy gear oils (e.g., ISO VG 150 to 680).

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
