Buyer Context: Lapping Carbon and Ceramic Seal Faces on the Workshop Floor
On a typical shift in a pump maintenance bay, carbon and ceramic seal faces come off the equipment with wear patterns that can only be corrected by precise lapping and polishing. Teams handling these components need a plate that can hold flatness and provide consistent material removal across both brittle ceramic and softer carbon faces.
The Ceramic Lapping and Polishing Plate from Shanghai Trisun Parts Manufacture Co., Ltd. is positioned for exactly this kind of work. The product sits in the Tools & Hardware / Power Tools category and is listed for mechanical seal polishing, repair of seal faces, and grinding or lapping of all materials.
From loading bays where seal faces are staged for refurbishment to production lines that process multiple batches per shift, operators look for a plate that can adapt to existing lapping machines. The supplier lists compatibility with Lapmaster 26-inch polishing machines, Kemet table polishing machines, 15-inch table lapping machines, 18-inch lightband polishing machines, and 24-inch polishing paste setups.
Product Description: A Grinding Disc for Seal Face Rework
The product is described as a ceramic lapping and polishing plate, with a Model No. value of ceramic and a material classification of Metal in the supplier's attribute sheet. It is designed as a grinding disc for objects including seal faces and metal faces, with a working style of three-roll.
For teams handling daily seal face repair, the plate provides a straightforward option for lapping carbon and ceramic. The supplier notes that the plate is intended for mechanical seal polishing and can be used on automatic lapping machines as well as manual setups. It is not listed with variable speed control.
Packaging is a wooden box, and the origin is China. The product is produced under the Trisun trademark with a production capacity of 500 sets per year.

Additional configuration details include standard size specification, wooden box transport packaging, HS code 84609090, and production capacity of 500 sets per year from a China origin.
Application Scenarios: Where the Plate Fits Daily Operations
In facilities that recondition mechanical seals, the plate can be used on a table lapping machine to restore flatness on carbon and ceramic faces before reassembly. The 480mm diameter option is specifically listed for cast graphite, while larger diameters suit bigger seal faces or batch processing.
For service shops that handle multiple pump types, the plate’s compatibility with Lapmaster and Kemet machines means it can be integrated into existing polishing stations without re-tooling the entire bench. The three-roll working style supports consistent contact pressure during lapping, which is important for maintaining flatness across the face.
On construction equipment or industrial maintenance sites where seals are repaired in place or in mobile tool cribs, the wooden box packaging helps protect the plate during storage and transport between job sites.
