Wear Resistant Ceramic Sleeves , Ceramic Plungers, Ceramic Seals , Ceramic Pump Parts
Mingrui ceramics combines advanced materials technology, precision manufacturing, and decades of engineering experience to solve real-world challenges in the energy, security & defense, industrial machinery, and other markets. We develop new ideas — applying deep expertise in engineered ceramics, advanced metals, and lightweight composite materials to deliver durable, multi-material products that extend performance lifetime, improve uptime, and reduce operating costs for our customers’ critical-service applications
Ceramic Plungers Ceramic plungers work exceptionally well for most saltwater, chemical, and metering applications. CoorsTek specially-formulated grades of ceramic allow a standard 8 RMS surface finish — dramatically extending packing life. Made of durable stainless steel, CoorsTek adapters successfully resist corrosion. CoorsTek uses a proprietary process to bond the ceramic body to the stainless steel adapter for reliable performance in extreme work environments. Ceramic plungers are available in hollow ceramic or solid ceramic designs. When corrosion and abrasion resistance are required and extended packing life is needed, ceramic plungers are unequaled in performance. Contact one of our specialists for specific application information.
Abrasion-resistant valves are recommended for applications where erosive particulates are causing premature failure of standard valves and suspended solids dictate the use of an open flow design. These valves are especially effective in saltwater disposal service, tank truck, and workover applications.
Product Description:
Typical applications for ceramics are wear-resistant sleeves, plungers, bearings, seals, balls and ball seat for valves. Parts are manufactured to prints according to pump and valve manufacturers specifications.
