&lpar1&rpar&interval High fracture toughness&semi
&lpar2&rpar&interval High hardness and dress in&solcorrosion resistance&semi
&lpar3&rpar&time period Higher operating temperature&semi
&lpar4&rpar&period Very good thermal shock resistance&semi
The UNIPRETEC ceramic metering pump module incorporates a ceramic piston&solvalve&solcylinder established with housing&period of time The housing for UNIPRETEC’S piston&solvalve&solcylinder sets are typically comprised of 316 CZPT Steel and Tefzel&period of time Custom made components can be utilised and are available upon ask for&interval The piston&solvalve&solcylinder set is sealed by the match of the piston into the cylinder&interval UNIPRETEC ceramic pump modules are optimistic displacement mechanisms that do not contain exterior valves and can run for hundreds of hundreds of thousands of cycles with no measurable wear&period of time
There are 3 kinds of pump modules&colon Rotary&comma Linear and Multiplex which are utilised for diverse apps dependent on the customer’s fluidic wants&period These pump modules purpose in a different way nonetheless&comma they share the identical standard characteristics that outcome in a low routine maintenance pump module&colon
&ast mated&comma serialized piston&solvalve&solcylinder sets
&ast limited clearance two&period3-five&period3 microns
&ast small Friction
&ast reduced fluid shear
&ast withstand program autoclaving and sterilization procedures
&ast chemically inert most acids&comma alkalines or solvents do not have an effect on the ceramics
&ast very difficult resist abrasion and dress in
&ast no external seals essential because of to restricted clearance of piston&solcylinder
&ast titanium conclude cap push match on to piston – gets rid of adhesive contamination troubles
&ast low routine maintenance
&ast flushing gland offered to support eradicate binding problems with specific fluids
