KD 6" Duplex Drilling Mud Pump
High-Pressure Hole Cleaning, V-Tooth Heavy Gearing & Modular Liner Assemblies
Engineering Overview & Purpose
The KD 6" duplex reciprocating mud pump is engineered for continuous borehole mud circulation in deep water well, geothermal, and exploratory drilling. Featuring double-acting twin pistons, cast iron housing, and interchangeable liners from 3" to 5", it delivers operating pressures up to 62 bar (895 psi).
Field Applications
- ✓ Continuous drilling mud circulation in deep wells
- ✓ Cuttings removal and hydrostatic head stabilization
- ✓ High-pressure cement injection and well servicing
Universal for all geological formations requiring positive displacement mud hydraulics.

Engineering Q&A Direct Answers
A: The duplex mud pump circulates high-pressure drilling fluid down through the drill string and out the bit nozzles to cool the cutting structure, lift rock cuttings up the annulus to the surface, and exert hydrostatic pressure against formation walls to prevent borehole collapse.
A: Smaller liners (e.g. 3") produce higher working pressures (up to 62 bar / 895 psi) at lower displacement volume, ideal for deep or tight holes. Larger liners (e.g. 5") yield maximum flow rate (12.5 L/stroke at 70 rpm) at lower pressure (21 bar / 310 psi), optimal for large-diameter top-hole drilling.
