Medical pump with advance ceramics
Medical pump is composed of high-density imported zirconia ceramics. The plunger rod and hydraulic cylinder of ceramics are processed by precision instruments. The ceramic surface is highly polished.No leakage of liquid occurs, thus achieving sealing.Because the surface is high polishing, low friction coefficient, high hardness, in mutual high-speed operation will not produce a lot of heat, and the thermal stability of ceramics is high, will not occur deformation, so can really achieve tens of millions of times running without wear.
The filling precision of Medical pump can be less than 0.25%, and its unique and precise design structure can continuously and stably maintain the high-precision output, free from environmental factors.Medical pump precision machining dimension can reach + / - 0.001mm, the narrowest machining groove width 0.1 x 100mm, linear tolerance up to 0.001mm, cylindricity up to 0.004mm.
The design of Medical pump used tilt Angle to realize the reciprocating movement of plunger rod.It has many advantages such as good stability, easy disassembly and cleaning.And when adjusting the filling volume as long as the Angle value can be achieved.Pump modules are special ceramic stainless steel structure, with corrosion resistance, long life, maintenance free features.
