Heavyweight Power Solutions High-Torque Industrial Mastery
DPA pumps are distributor-type rotary units that utilize a single rotating pumping element to deliver fuel to each cylinder sequentially—a highly efficient design essential for light commercial vehicles, older tractors, and stationary industrial machinery. Revcounts Diesel & Engineering specializes in calibrating these intricate hydraulic systems to resolve critical operational issues such as hard starting, sudden power loss, and erratic idling across premium brands like Delphi.
Using state-of-the-art Hartridge and Bosch test benches, our technicians verify internal transfer pressures, metering valve responses, and maximum fuel delivery limits for every rebuild. We ensure that hydraulic heads, drive shafts, and advance mechanisms are perfectly aligned to OEM standards; because all machine work and fluid testing are performed fully in-house, we deliver professional repairs that significantly extend the service life of your equipment.
