The ceramic liner is used as a kind of mud pump fluid end parts in the oil drilling industry.
Compared with the metal liner, the ceramic liner is wear and corrosion resistant and has extended working life. The ceramic liner helps reduce drilling cost and labor intensity. Made of internationally advanced, new material toughened zirconium oxide, the liner provides fracture toughness of K10-15Mpa (10 times that of the traditional one), and bending strength of σ600-800Mpa. The ceramic liner has excellent wear and corrosion resisting properties, with the Weber number being m18 and the elastic modulus of E200Gpa.
The ceramic liner is the best choice for high pressure mud pumps. It is manufactured strictly in accordance with specific technical standards by use of advanced processing techniques. The ceramic liner comes in various specifications, which come in Φ150～180×310～440mm.

The do's and don'ts
1. Please check the inlet pipe and outlet pipe before starting the mud pump.
2. Please make sure the lubrication oil is applied to the bearings fully.
3. The high pressure clear water pump is necessary to transmit the water to the leak-proof filling materials.
4. Don't turn off the flushing pump when the mud pump is working, or the sealed mud pump parts will wear away rapidly.
5. Leave proper space between the vane wheel and the shield so as to ensure long working life of the mud pump. Otherwise, the mud pump will make big noise and vibration, and the mud pump parts may be easily worn out. So install the mud pump strictly according to the instruction and adjust the space by the bolt on the bearings.
6. Since the suction height is measured in the course of water delivery, it will be different when transferring mud. So take these factors into consideration when using the mud pump.
When choosing and using the mud pump parts, pay special attention to the quality of the liner, cylinder head, pull rod, piston, piston rod, plunger rod, leather cup, and draining valve, among others.
