Cummins Launches Tier 2 QSK38 & QSK50 for Drilling Applications

Posted on October 23, 2007

Cummins Inc., launched the Tier 2 QSK38 and QSK50 drilling power modules at the Louisiana Gulf Coast Oil Exposition in Lafayette, Lousiana, U.S.A. Building on the success of their V12 and V16 KV Series, Cummins QSK product line has taken the durability of the base engine and enhanced it with the proven technology of Cummins Quantum System electronics and modular common rail fuel system found on their Tier 2 QSK19 and QSK60 engines. This performance and technology upgrade ensures not only Tier 2 emissions compliance, but also quieter operation, better fuel economy, smoother power delivery and better idle stability.

The QSK38 drilling power module is rated 771 kW at 1200 r/min and is integrated with a Cummins-manufactured AVK DSG86M generator at 1200 kVA and 600 volts. The QSK50 provides 1104 kW at 1200 r/min and is coupled with a Cummins-manufactured AVK DSG86L6 generator at 1750 kVA and 600 volts. Both of these products are ideal for the durability, reliability and power density requirements of high-hour and hard duty cycle applications such as SCR drilling modules. Both the QSK38 and QSK50 engines share 70% of their parts with their corresponding KV predecessors and, with a track record of over 1000 38-liter and 1000 50-liter engines produced annually, proven reliability is assured every time.

"We've taken the long-proven Cummins KV 38 and 50-liter engines to the next level in performance and provided a high level of engine sociability along with emissions compliance. Cummins continuous investment in our proven products and technology goes a long way in enabling our customers to achieve the highest uptime at the lowest possible cost at every emissions level," said Jim Trueblood, vice president of Cummins high-horsepower engineering.
