High-Viscosity Motorized Grease Pump with Follower Plate

Pumping heavy, high-viscosity grease (NLGI 2 or 3) often leads to a problem called "cavitation," where the pump sucks a hole in the grease and begins pumping air. The Motorized Grease Pump with Follower Plate permanently solves this. It utilizes a weighted, spring-loaded plate that sits directly on top of the grease inside the reservoir. As grease is consumed, the plate physically pushes the remaining grease down into the pump intake, ensuring a continuous, air-free prime.

Key Advantages & Benefits:

  • Zero Cavitation: Guarantees continuous pump priming, even with extremely thick, non-leveling greases.
  • Maximum Reservoir Usage: Wipes the walls of the reservoir clean as it descends, minimizing wasted grease.
  • Prevents Contamination: The plate acts as a physical barrier, keeping airborne dust and moisture away from the grease surface.
  • Reliable Delivery: Ensures your progressive or dual-line distributors receive solid grease, not air bubbles.

Versatile Applications:

  • Heavy earthmoving equipment
  • Wind turbine main shaft bearings
  • Industrial forging presses
  • Marine winches and cranes

Frequently Asked Questions (FAQ):

  • Q: How do I refill a pump with a follower plate? A: You must refill it from the bottom up using a bulk fill port and a transfer pump. This pushes the follower plate back to the top of the reservoir without introducing air.
  • Q: Will it work in cold environments? A: Yes, the physical pressure of the follower plate is especially beneficial in cold environments where grease naturally thickens and refuses to flow by gravity.

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.
