3mm 6mm 9mm Ceramic Shaft for Micro Pump Ceramic Pump Components
Pump Component Applications
Centrifugal Pump – alumina parts are used for transportation of organic solvents, acids and slurry
Gear Pump – ceramic plain bearings are used for high viscosity, corrosive and abrasive fluids
Micro Pump – RTZ ceramic shafts, gears and other parts for precision delivery of fluids
Cavity Pump – heat and corrosion resistant ceramic rotors and stators
Ball and Faucet Valves – ceramics are used to provide excellent sealing quality and superior wear resistance
An improved gear micropump (10) for delivering corrosive materials, particularly photographic materials, such as dyes and emulsions, has a pair of intermeshing gears (16,18) rotatably mounted on zirconia ceramic shafts (24,26). The ceramic shafts of the invention may be formed from zirconia and zirconia composite materials. The gear micropump (10) having the zirconia ceramic shafts (24,26) eliminates pulsation during fluid delivery and is resistant to wear and abrasion. Moreover the zirconia ceramic shafts (24,26) are strongly resistant to chemicals like photographic emulsions and dyes and, therefore, do not contaminate product with corrosive materials.
