It is made of Silicon Carbide or Intensify Toughness Alumina material which is authorized by some Chinese and American companies. Based on the advantages such as HRA90, super grinding resistance and less coefficient of linear expansion etc. The working life will be around 3000 - 5000 hours and is several more times than Dual Metal Liner under normal working condition.

The Special Ceramic Pump Valve, with high temperature-resistance and anticorrosion, can replace common pump valve. Also with drippy structure and guiding device, the Special Ceramic Pump Valve can be shut down quickly with excellent sealing security and guiding fit exactly; the flow gate is 1.4 times as common pump valve, it increases complete pump barrel filling and working life a lot. 

The Ceramic Sucker Rod Pump, assembled together with special heat-resistant & anti-corrosive alloy steel pump cartridge and anti-corrosive& high temperature-resistant ceramic plunger, can resist high temperature working condition of more than 300°C and also possesses the advantages such as anti-corrosion, non-forming encrustation and long working life.

Due to the function of composite shock absorption device, the Ceramic Plunger can bring the buffing powder of 30000Pa. Some other technical indexes are:

It is not corroded by acid under the well, therefore, the working life of the Ceramic Plunger is several times more than common metal plunger.
