Corrosion resisting Zirconia ceramic shaft for petroleum and pump innovacera

1.  Introduction:

The zirconia ceramic plunger both surface are zirconia ceramics, the plunger column and the metal handle use mechanically joined, simultaneously the mastic are sticked between ceramics and the metal handle. Compares with the existing ceramic plunger, our product prevent the thread less crowded, have reliable joint and high intensity; Simultaneously zirconia ceramic plunger service life are 10 times longer than metal plunger. Now the products have been widely applied in the petroleum, chemical, food machinery ram pumps and so on.

Zirconia ceramics materials provide excellent erosion, corrosion and abrasion resistance along with temperature resistance, fracture toughness and strength. These ceramic components are used in extreme service applications that take advantage of their superior wear and corrosion resistance.
