New Delivery for PTFE Graphite Packing with Aramid Corner to San Diego Factories

PTFE graphite packing with aramid corner is made from aramid yarns impregnated with PTFE, while the friction faces are made of graphite PTFE yarns. The graphite particle in PTFE yarn enhances the heat exchange efficiency.

Technical Data Sheet

 Application Area

It affords longer service life under severe conditions which conventional asbestos packing can bot provide satisfaction, such as mine, tin ore, paper pulp, feed water pump of power stations, etc.

White Knight PEM050 electronic metering pumps offer adjustable flow rates for use in single-wafer processing tools or premix vessels to ensure exact chemistry mixtures, and allow for in-situ mixing directly at the head.

These stepper-driven pumps accurately dispense 1-50ml of high-purity chemicals in Teflon® (PTFE) fluid paths for chemical replenishing, blending, dosing and spiking applications, as well as cleaning CVD equipment and in photolithography. They are ideal for photoresist, etch and clean processes, peroxide spiking in piranha mixtures, and other blending of chemical mixtures into process tanks prior to the introduction of substrates.

PEM050 pumps feature fully-supported rolling diaphragms, which maximize discharge pressure capabilities. Positive control valves ensure accuracy by eliminating the variability that is typical of check valves. They offer up to 5 discharge ports that can be independently controlled with programmable system logic.
