Mud Pump Connecting Link Rod
Our triplex mud pump connecting rod acts as a core transmission component for drilling rig power ends. It fits high-pressure plunger pumps used in onshore & offshore drilling, cementing, fracturing and shale oil & gas extraction. The rod serves as a direct interchangeable replacement part for triplex pumps of mainstream brands including EMSCO, BOMCO, Oilwell and Gardner Denver. We also develop custom special connecting rods for API-compliant and non-API well testing & workover pumps, rated for drilling operations up to 7500 PSI maximum working pressure.
Key Configurations
1. Raw material: Cast AISI 4135 / AISI 4140 alloy steel, equivalent to 35CrMo/42CrMo. Custom alloy materials are available upon special working condition requests.
2. Production workflow: Integrated premium heat treatment and multi-spindle CNC precision machining, making overall mechanical properties exceed official API industry standards.
3. Quality management: Full closed-loop QC and non-destructive inspection throughout production, effectively avoiding hidden flaws such as internal cracks and sand holes.
4. Universal compatibility: Standard dimensional design allows full interchangeability with most mainstream triplex mud pumps and matching power end assemblies without equipment modification.
5. Supply service: Standard connecting rods of all sizes are kept in stock for fast delivery. Custom special structure rods complying with API or non-API specifications are supported for unique operation demands.
Core Product Advantages
1. High-strength cast alloy steel base, strong resistance to alternating heavy loads Integrally cast connecting rods with 35CrMo/42CrMo matrix deliver outstanding tensile, compressive and bending resistance. The material can withstand continuous cyclic stress generated during reciprocating pump operation and prevent catastrophic breakdown that would destroy the whole power end.
2. CNC precision machining plus professional heat treatment, performance superior to API standards Multi-spindle CNC equipment ensures high-precision machining of big end and small end mounting positions. Complete quenching & tempering heat treatment delivers uniform hardness and minimal deformation, maintaining excellent coaxiality during power transmission and reducing abnormal abrasion of bearings and bushings.
3. Rigorous full-process inspection for extended fatigue service life Multiple rounds of flaw detection are conducted from rough casting to finished goods to eliminate internal defects. Stable fatigue resistance significantly extends service life and cuts frequent maintenance downtime on drilling sites.
4. Wide interchangeability to save installation and maintenance costs Uniform assembly dimensions fit most domestic and overseas triplex mud pumps. Direct replacement without secondary processing shortens equipment disassembly and assembly time, minimizing rig non-production periods.
5. Abundant in-stock goods plus flexible customization for diverse extraction scenarios Full-size standard connecting rods are always in stock for quick shipment. Custom non-standard rods can be engineered for offshore rigs, deep well testing and fracturing jobs, meeting both API compliance and personalized equipment parameter requirements.
