Connecting Rod

💎 Downhole Drilling Quality Forged Connecting Rod for Elephant CBW-Series Mud Pumps – Maximize HDD Uptime

The connecting rod is the most critical dynamic component in the power end of your Elephant CBW-Series Triplex Piston Pump. Engineered to convert the rotational motion of the crankshaft into the 135mm stroke required for the CBW-Series, this forged alloy steel rod ensures maximum hydraulic efficiency and minimizes power loss. For high-demand applications like Horizontal Directional Drilling (HDD), choosing this precision-engineered replacement guarantees performance identical to (or exceeding) the Original Equipment Manufacturer standard, protecting your investment and preventing catastrophic power end failure.

Key Features & Benefits:

Perfect Fit Guarantee: Specifically designed and machined for the CBW-Series pump model, ensuring 100% interchangeability with the original rod.
Optimized Material: Crafted from high-tensile strength, heat-treated 35CrMo alloy steel for exceptional fatigue life and resistance to high cyclic loading.
Precision Geometry: Critical bore centres are controlled to micrometre tolerances to maintain the CBW-Series exact 135 mm stroke, ensuring proper crosshead alignment and smooth operation.
Certified Quality: Manufactured under strict ISO 9001 quality management systems, often compliant with API Spec 7K standards for drilling equipment.
Application-Specific: Built to endure the high-pressure, high-flow demands of 90-ton class HDD rigs that typically utilize the CBW-Series.
