Mechanical DB Rotary

Proven and time-tested

50 to 200 HP AND 750 BAR NE

DB Mechanical Rotary pumps have been fueling diesel engines since we invented the technology more than six decades ago. Our revolutionary design has stood the test of time with millions of these pumps in-use worldwide. With an inlet metered design, our rotary pumps offer superior governing and provide the best regulation performance of mechanical pump-line-nozzle fuel injection equipment.
