GPE supplies 3NB1300 and 3NB1600 triplex mud pumps for land drilling rigs, deep-well drilling, geothermal projects, workover service and high-pressure mud circulation. The 3NB series is especially relevant where a metric liner system and 3NB-series replacement strategy are required.
Choose 3NB1300 for 1300 HP-class projects using 130–180 mm metric liners. Choose 3NB1600 when the project requires 1600 HP-class power, larger-rig duty and metric liners up to 190 mm. Final selection should still be confirmed from flow, pressure, liner size and drive conditions.
This category page is the commercial comparison hub for the 3NB series. Each product page remains responsible for its own detailed technical specifications and application information.

Both are triplex reciprocating mud pumps with 12 in stroke and metric liner systems. The main commercial difference is power class, liner range and the drilling duty each model is intended to support.
| Model | Rated Input Power | Stroke | SPM | Published Max. Pressure | Metric Liner Range | Typical Positioning | Product |
|---|---|---|---|---|---|---|---|
| 3NB1300 | 970 kW / 1300 HP | 12 in | 120 | Up to 5,000 psi | 130 / 140 / 150 / 160 / 170 / 180 mm | Land rigs, deep wells, geothermal, CBM, workover and metric 3NB replacement projects | View 3NB1300 → |
| 3NB1600 | 1193 kW / 1600 HP | 12 in | 120 | Up to 5,000 psi | 140 / 150 / 160 / 170 / 180 / 190 mm | Large land rigs, deep wells, ERD, geothermal and higher-power 3NB drilling projects | View 3NB1600 → |
Note: Maximum working pressure depends on liner size and operating configuration. Maximum pressure and maximum displacement should not be assumed to occur at the same operating point.
Start from the required power class and liner system, then confirm the final selection from actual flow, pressure and rig conditions.
Do not select the pump from horsepower or well depth alone. Confirm the operating point and rig interface first.
Define the circulation rate required by the drilling program, hole section and mud system.
Confirm standpipe pressure and the operating pressure required by the full circulation system.
Match the 1300 HP or 1600 HP pump class to the actual electric, diesel or mechanical drive available.
Balance liner diameter against displacement, pressure requirement and expected wear life.
Avoid assuming that every 3NB pump or spare part is automatically interchangeable. Final compatibility should be checked against the actual model, part number, drawing and controlled dimensions.
GPE supports model confirmation, documentation and long-term replacement planning for drilling contractors, rig owners, EPC buyers and distributors.
Existing 3NB model information, drawings and interface dimensions can be reviewed before configuration is confirmed.
Inspection, testing and required project documents can be defined as part of the quotation and production scope.
Metric liners, pistons, valves, seats, fluid-end parts and power-end spares can be planned with the selected pump.
Keep the 3NB category focused on the commercial series intent while other pages handle broader mud-pump and alternative-series searches.
Send the required flow rate, working pressure, available drive power, preferred model and any existing 3NB pump drawing. GPE can review the configuration before quotation.
