Proven & 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.
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.
Unique Features
Automatic Advance
- Senses fuel demand and adjusts fuel delivery
- Delivers consistent power output
Optional Built-in Advance & Timing Mechanisms
- Speed and Light Load Advance
- Cold-start and Warm-up Timing Advance
- Adjustable Speed Regulation (3-5%)
- Low Speed Fuel Limiter
- Locked Drive Shaft Timing
Fuel Curve Rate Shaping
- Enables adjustment of the fuel curve between peak torque and rated speed.
- Makes the engine back up to peak torque RPM when a load is placed on the engine.
- Does not affect peak torque fuel.
Built-in Transfer Pump
- Eliminates the need for a separate lift pump.
- Insensitive to fuel quality and temperature variation.
- Ensures reliability in governing operation.
- Built for precision and robust operation.
Pumping Plungers
- Available with 2, 3 or 4 plungers.
- Unique design reduces part count.
- Low leakage piston.
- Rotary design with porting bushing eliminates check valves.
