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.

Mechanical Rotary


Flexible Design

Optional performance features for optimized timing and adjustable speed regulation, cold start and warm-up timing advance and low-speed fuel limitation for reduced emissions.


Wide Application Range

DB pumps are ideal for a wide range of applications up to Tier 3/Stage IIIA and can be used with 3, 4 and 6 cylinder diesel engines up to 40 BHP (30kW) per cylinder.


Efficient Performance

Specially designed internal components enables compatibility with low-viscosity fuels. Built in automatic advance delivers optimum engine performance and emissions control.
