99.9% Al2O3 Alumina Ceramic Shafts Custom Zirconia Shafts For Gear Micropump

Zirconia Shafts 99.9% Al2O3 Alumina Ceramic Shafts For Gear Micropump Mini Pump Ceramic Shafts

Gear micropump shafts were also made from 99.9% pure Al2 O3 (ALCOA grade AG-16), exactly the same way as the zirconia shafts. A set of plastic driving and driven gears was equipped with alumina shafts in a gear micropump and ran with only water. After a short while the fluid delivery speed of the pump started to fluctuate and the pressure dropped and after a while it ceased to work. The pump was disassembled and thoroughly examined. It was noticed that the seat on which the shaft was residing was slightly worn out and one of the shafts (driving gear shaft) was chipped and non-functional. A new pair of shafts were installed and pumped photographic emulsion for experimental web coating. After a short duration (approximately 24 hours), the pump delivery system started mildly pulsating causing non-uniform coating. The pump was allowed to run for longer than a week while the pulsation persisted and generated non-uniform coating. The pump was stopped, disassembled, and examined. The shafts chipped in several places and many 15 components inside the pump had wear marks. Thus, it was concluded that alumina ceramic shafts are not a good substitute for stainless steel in this application.

Although zirconia is known to be very hard and wear-resistant, yet it has high enough fracture toughness to behave like a steel. Many ceramics like Al2 O3, SiC, Si3 N4, etc. are more brittle and very prone to chipping in applications such as shafts in a gear pump. Also, many structural ceramics have higher elastic modulus and as a result they are more stiff than stainless steel and are not forgiving. Zirconia has elastic modulus comparable to stainless steel (Stainless steel: 30 mpsi and zirconia 32 mpsi). In this application, plastic gears are used and they are not of very high 25 precision. So, the shafts need to be a little forgiving to adjust for any misalignment in the enmeshing gears. Zirconia shafts are more forgiving than other structural ceramics. Alumina toughened zirconia (5-50% by weight alumina) also behaves similarly. In other words, zirconia and alumina toughened zirconia are surprisingly the best ceramic materials for this application.

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.

Main Features:
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4) High electrical resistivity: alumina is an electrically insulating material.
5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
