Whether running mudpumps and draworks on mechanical installations or driving SCR sets for electric rigs, the Cummins QSK50 engines provide optimum performance, reliability, and versatility for drilling.
This rugged 4-cycle Cummins industrial diesel delivers reliable power, low emissions, and fast response to load changes.
The QSK50 high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. Fuel is injected at pressures exceeding 25,000 psi. This results in better utilization of fuel with fewer emissions. Getting more energy out of every drop of diesel fuel also results in greater power.
