Heavy-duty industrial diesel power units engineered specifically for high-pressure oilfield fracturing, cementing, and mud pumping operations. Built on heavy-scantling cast-iron blocks with oversized cooling loops, these engines maintain continuous, high-torque output under peak fluid loads and severe, dust-laden drilling environments. Designed for direct drop-in integration into OEM trailers, frac skids, and well-service workover units.

Key Features

High Torque Rise at Low RPM: Sustained torque delivery prevents engine lugging during sudden well pressure spikes and heavy fluid displacement cycles.

Heavy-Duty Cooling Package: Oversized core radiators and charge-air coolers engineered for continuous-duty operation in ambient temperatures up to 50°C.

Vibration-Resistant Structural Skids: Heavy-walled structural steel skid bases integrated with heavy-duty vibration isolators to withstand high-frequency dynamic loads during pressure pumping.

Modular Electronic Controls (ECM): Factory-integrated engine control modules monitoring oil pressure, rail pressure, coolant temperature, and automated engine protection shutdowns.

Harsh-Environment Harnessing: Sealed Deutsch connectors and braided, oil- and abrasion-resistant wiring harnesses built to resist mud, salt spray, and chemical exposure.

Available Options & Customization

Enclosures & Thermal Packages: Open field skids, sound-attenuated weather enclosures, or arctic winterization kits with block and fluid heaters for cold starts down to -40°C.

Starting Configuration: Heavy-duty dual electric starting or pneumatic air-starter systems complete with air receiver tanks and pressure regulators.

Instrumentation & Control: Local analog gauge panels or remote digital PLC control interfaces supporting J1939 CANbus protocols.

Exhaust Systems: Spark arrestor mufflers, critical-grade silencers, and thermal exhaust insulation blankets.

Quality Control & Manufacturing Capabilities

Machining Precision: Engine blocks undergo CNC line-boring and high-tolerance dimensional verification via Coordinate Measuring Machines (CMM) prior to crankshaft fitting.

100% Dynamometer Testing: Every assembled engine undergoes a mandatory minimum 4-hour full-load dynamometer test on water-brake or electronic dynos to verify horsepower, torque curves, and thermal stability under 100% rated load.

Integrity Inspection: Pressurized fluid-gallery tests and electronic sensor calibration checks performed before final sign-off.

Facility Standards: Built in our ISO 9001 certified assembly plant utilizing overhead crane-bay rigging, torque-controlled fastening tools, and contamination-free fuel system sub-assembly stations.

Packaging & Shipping

Structural Securing: Bolted onto heavy-gauge structural steel shipping skids with custom-welded blocking to prevent transit shifting.

Corrosion & Moisture Protection: VCI (Volatile Corrosion Inhibitor) packaging bags seal the entire engine; intake/exhaust ports and fluid openings securely capped and sealed.

Lifting & Handling: Certified lifting lugs and spreader-bar attachment points stamped with Working Load Limits (WLL) for safe field and port crane handling.

Documentation & Logistics: Delivered with complete export packing lists, mill test reports, lifting certificates, and customs clearance paperwork via flatbed or container freight.

Frequently Asked Questions

Q: Are these engines compliant with EPA Tier 4 Final regulations for domestic US operations?

A: Yes. We supply EPA Tier 4 Final certified configurations equipped with integrated SCR/DPF aftertreatment systems, as well as Tier 2 or non-regulated configurations for international export jurisdictions.

Q: Can the skid bolt patterns match our existing Gardner Denver or SPM pump trailers?

A: Yes. Our engineering team matches mounting dimensions, alignment tolerances, and drive-shaft coupling interfaces directly to your trailer blueprint to eliminate field modification work.

Q: What is the standard production lead time?

A: Standard engine builds ship within 4 to 6 weeks from order confirmation and drawing approval. Custom skid fabrication, specialized enclosures, or complex PLC integrations require 8 to 12 weeks.

Q: What warranty coverage is included?

A: Standard industrial warranty covers 12 months from the date of commissioning or 2,000 operating hours (whichever occurs first) against defects in materials and workmanship. Extended coverage options are available upon request.

Q: Are replacement filters and overhaul parts locally accessible?

A: Yes. Because these units utilize standard Cummins commercial architecture, replacement filters, fuel injectors, turbos, and overhaul kits are globally accessible through standard supply channels.

Q: What test data is provided with the engine upon delivery?

A: Every unit ships with an individual dynamometer test report verifying performance curves (horsepower, torque, and fuel consumption across step-load intervals), along with CMM inspection records and warranty documentation.
