Alumina Ceramic Parts Ceramic Metering Pump Dosing Pump Pharmaceutical Filling Line Volume 0.5ml Corrosion Resistance

Yttria-stabilized zirconia ceramics’ hardness reaches HV2500, and has good properties as wear resistance, anti-corrosion, high temperature resistance, as well as excellent finish surface. In addition to its good properties of elasticity module and high hardness, it produces no non-toxic materials when working. So it is an ideal material for dosing pumps applied in fluid filling equipment of medicine.

A metering pump made from zirconia ceramic material has the following advantages:

1. The extremely sluggishness of metallic oxide stands acid or alkali fluid without corrosion, and bear high temperature in the working environment; accordingly it also meet the strict requirement of regular disinfection and sterilization by high temperature.
2. The striking wear resistance incurred by hardness make sure a 5-8times longer service life, than counterparts made from chrome-coated stainless steel, with nearly neglected material release, which has no pollution impact on the medical fluid.
3. The compactness of crystal structure makes the surface polish of working area extremely good, usually is about Ra0.15, which greatly reduces friction and leaves few fluid residue in the pump cylinder. The smooth surface even makes the metering pump work continually without fluid in it and get no damage.
4. The extremely low thermal expansion makes a less clearance between the cylinder and the piston, which helps maintain a stable filling precision.
