Typical Applications
The 3NB1300 mud pump is suitable for:
- Land drilling rigs
- Deep well drilling
- Geothermal drilling
- Coalbed methane drilling

Why Choose 3NB1300 Instead of F-1300?
The 3NB1300 and F-1300 mud pumps are both commonly used in the 1300HP mud pump range, but they should not be positioned as the same product page.
The F-1300 mud pump is commonly associated with standard F-series structure and inch-based liner sizing. It is more familiar to buyers using North American-style F-series rigs and spare parts systems.
The 3NB1300 mud pump is better positioned for buyers who require a metric liner system, compact 3NB-series configuration, and metric spare parts planning. This makes it suitable for international rig projects where metric components and 3NB-series compatibility are preferred.
For buyers comparing models:
- Choose F-1300 when the project requires a standard F-series 1300HP mud pump with inch-based liner options.
- Choose 3NB1300 when the project requires a 1300HP 3NB-series mud pump with metric liner sizes from 130mm to 180mm.
- Choose 3NB1600 when the project requires a higher-power 3NB-series mud pump with 1600HP capacity and metric liner sizes up to 190mm.
- Choose UNBT 1180L when the project requires a 1600HP UNBT-series pump with helical gear transmission and low pressure fluctuation.
Metric Liner System and Displacement Flexibility
The main difference of the 3NB1300 mud pump is its metric liner system. Available liner sizes include 130mm, 140mm, 150mm, 160mm, 170mm, and 180mm, allowing buyers to match pressure and displacement requirements according to drilling conditions.
Larger liner sizes are used when higher displacement is required, while smaller liner sizes are selected when higher pressure performance is needed. This flexibility helps drilling contractors adapt the same pump platform to different drilling stages and mud circulation requirements.
Structural Features
Compact 3NB-Series Power End
The 3NB1300 power end is designed for high-load drilling and continuous-duty operation while maintaining a compact 3NB-series structure for land rig installation and transportation convenience.
High-Pressure Fluid End
The fluid end supports high-pressure drilling mud circulation up to 5000 psi and uses API #7 valve-related components. Metric liners, pistons, valves, seats, and fluid end parts can be supplied according to project requirements.
3NB-Series Maintenance Support
The 3NB1300 mud pump is suitable for buyers already using 3NB-series equipment or metric spare parts systems. Standard maintenance parts can be supplied to help reduce downtime and simplify inventory planning.
