Wear Resistant Pump Ceramic Piston / Ceramic Sleeve Piston with Low
Friction
Tag Key words : Pump Ceramic Piston / Ceramic Sleeve Piston
What is the use potential of high performance ceramics for current
and future requirements in engine manufacturing? The
Fraunhofer-Institutes LBF and IWM are analysing this in close
collaboration with industry partners from the motor and ceramics
industry. The starting point of the ongoing investigations in this
area is the Pump Ceramic Piston / Ceramic Sleeve Piston used in diesel engines, because great development and sales
potential are expected for this concept.
Mingrui extensive range of Pump Ceramic Piston / Ceramic Sleeve Piston enables us to offer a solution for every application. Sizes,
compositions and materials can be varied based on customer specific
requirements. Our most widely used Alumina tubing is available in a
broad range of sizes and multi-bore configurations. Common
applications include furnace and thermo-couple tubes.
Pump Ceramic Piston / Ceramic Sleeve Pistoncan be further machined into standoffs, washers and step bushings,
which at lower quantities may be more cost effective than pressing
processes, where costly tooling charges are typically required.
We offerPump Ceramic Piston / Ceramic Sleeve Pistonin different range from .020” to 8.250” (0.30mm – 500mm).
