Specifications

According to API Spec 7K and the China Petroleum and Natural Gas Industry Standards

Product main features:

 

Fluid end: intake flange and discharge flange is strictly in accordance with ANSI and API standard. It can be interchangeable.

Power end: the tooth of the transmission gear is an involute shape, runs smoothly and has high efficiency and long lifetime. Crankshaft is integral hollow casting. The end is splash lubricated. It isn’t belong to wearing parts so it is difficult to interchangeable in generalized case. 

Type:

 

F-series mud pumps

3NB series mud pumps

F series mud pumps are single horizontal triplex piston pumps. In the deep and ultra-deep wells, the drilling process cycle of drilling fluid, cleaning the bottom of the well to carry cuttings, cooling and lubricating bits and reinforced sidewall, used in conjunction with high pressure water jet bit rock crusher help improve drilling speed; Meanwhile, can also provide a mobile drilling mud pit as a driving force.
