New Patent Granted – 4-in-1 Sealing Technology
2026-08-03
We're proud to announce: Lepu Machinery has been granted a new utility model patent by the China National Intellectual Property Administration (CNIPA).
Patent No.: 202522225205.6
Title: Indirect Cooling Seal Assembly, Low-Speed Rotor Pump, Cam Pump, and Centrifugal Pump Seal Assembly
Granted: July 24, 2026
What makes this patent special:
A single patent protecting 4 integrated sealing solutions — designed for pumps that operate under demanding thermal and mechanical loads.
The "indirect cooling" architecture is the heart of this innovation:
· Coolant never directly contacts the process media — ideal for sanitary, hazardous, or high-purity applications
· Stable seal face temperature extends service life under continuous duty
· Modular design that adapts to rotor pumps, cam pumps, and centrifugal pumps alike
From the workshop floor to the patent office — this is how Chinese manufacturers earn their technical reputation, one innovation at a time.
Looking for a sealing partner with serious R&D behind the product? Let's talk.
