Products Description
Developed to withstand severe thermal expansion and high working loads, our Bimetal High Pressure Pump Thrust Plate incorporates a specialized CuPb24Sn4 high-lead bronze layer fused to a structural steel core. We manufacture this heavy-duty Bimetal High Pressure Pump Thrust Plate for high-pressure gear and vane pumps running continuously in metallurgical machinery, surface mining equipment, and heavy infrastructure plants. By reducing end-face oil bypass by over 40% compared to standard plates, our Bimetal High Pressure Pump Thrust Plate maintains stable system pressure through frequent start-stop cycles and heavy mechanical impacts.
Application Scenarios
- Primary thrust sealing in high-pressure gear and vane pump assemblies.
- High-load hydraulic systems in metallurgical rolling mills and surface mining haulers.
- Critical fluid power units operating under high-temperature and shock-load conditions.

FAQ
Q: What makes this plate suitable for temperatures up to 280°C?
A: The CuPb24Sn4 alloy provides thermal anti-welding characteristics that prevent bronze transfer to rotating gears under boundary lubrication and elevated heat.
Q: How does our team receive production progress updates?
A: We share regular video and photographic updates from blank sintering to CNC grinding, ensuring full milestone visibility.
