Ceramic Filling Pump with Ceramic Pump Manufacturer

Alumina Zirconia Ceramic Filling Pump

High precision Alumina Zirconia Ceramic Pump/ Valve

Ceramic Filling Pump widely used in pharmaceutical, chemical, food, scientific research need filling precision instruments such as the minimum filling quantity: 1 ml biggest filling quantity: 1000 ml filling accuracy: 0.5% or less use temperature: 10 ℃ and 40 ℃.

It has the following characteristics:
(1) high performance technical ceramic material, with high hardness, wear resistance, high temperature resistance, corrosion resistance and other properties.Ensure the material performance is reliable.
(2) the microporous structure obtained from the plunger working face with unique processing means has self-lubricating effect, which changes the mechanism of sliding friction and lubrication of the traditional plunger pump.
(3) the surface of the inner cavity is fluid structure without dead Angle and groove.The surface of inner cavity and the surface of plunger are processed to mirror surface by advanced high-precision internal and external cylindrical grinder.
(4) the pump body structure is made of 316L stainless steel with seal for easy disassembly.
(5) this kind of product has been tested for its corrosion resistance, ph resistance and safety performance, and its indicators have reached the level of similar foreign products.
(6) the shape and size can be designed and processed according to the needs of users.

Ceramic Filling Pump material composition:
· 95%--99.99% Alumina (Al2O3) · Silicon Carbide · Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2)
· YTZP: Yttria partially stabilized Zirconia (ZrO2)
· ZDY: Yttria fully stabilized Zirconia (ZrO2)

Properties:
Chemical inertness
Resistance to high wear
Resistance to thermal conductivity
Resistance to electrical conductivity
