Features & Benefits:

Bi-metal Liner

Features

Boban bimetal liner, international standard complaint, provides wear-resistant outer sleeve and high chrome corrosion-resistant inner sleeve. The material of liner is ZG45 steel, the high chrome liner has high rigidity of HRC≥61-65 after heat treatment.

Advantages
Production Process: The bi-metal cylinder Liner of our company combined with the advantages of abrasion hot-forging out liner and anticorrosion high chrome inner liner. The out liner is made of high quality carbon steel by hot pressing forming. Its tensile strength is over 900000psi. The inner liner is made of high-chromium alloy by centrifugal casting. The bimetal liner offers long service life of about 1000 hours, which is 2 to 3 times the lifetime of common ones in severe environment.

Ceramic Liner

Features

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.
Advantages
1. 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.
2. Ceramic liner widely used in tough environments such as deep oil reservoirs, hard stratum, and offshore oil and natural gas exploitation.
3. The service life is 5 times higher than bi-metal liner, up to 4000 hours.
5. It can improve drilling efficiency and reduce the cost of maintenance and labor.
4. Zirconia ceramic liner has various advantages, such as wear-resistance, erosion-resistance, high pressure-resistance, high hardness, and so on.

Mud Pump Valve Assembly

Features

Mud pump valve assembly is the key component of the hydraulic end of the mud pump. The valve assembly consists of valve body, valve rubber, valve nut, guide frame, gland, clamp spring, steel ball, etc. (i.e. valve assembly with valve seat removed).

Mud Pump Piston
