Diesel Engineering Services repair and calibrate the following Delphi (Lucas) Injection Pumps:

Pump Type Common Delphi Models Matching Injector Type Typical Applications Key Notes
In-Line Mechanical Pump CAV / Lucas in-line pumps Mechanical pintle or multi-hole injectors Agricultural tractors, industrial engines, older trucks Rugged, simple; mostly phased out in road vehicles
Rotary Distributor Pump DPA series, DP200, DP210, DP310 Mechanical (DPA, DP200) or electronic solenoid injectors (DP210, DP310) Passenger cars, vans, light trucks, small tractors Compact, cost-effective; later models allow electronic timing
Electronic Unit Pump (EUP) Delphi EUP systems Separate multi-hole injectors (mechanical or solenoid-controlled) Heavy-duty trucks, buses Each cylinder has its own camshaft-driven pump
Electronic Unit Injector (EUI) Delphi EUI systems Unit injectors (pump + nozzle in one body) Heavy-duty trucks (Volvo, Renault, Mack), marine, off-highway High pressure with individual electronic control
Common Rail High-Pressure Pump DFP1, DFP3, DFP6, DFP7 Solenoid or piezo common rail injectors Modern diesel cars, vans, trucks, off-highway machinery Very high pressures (~2,500 bar), multiple injections per stroke
Electronic Unit Pump Injector (EUPI) Delphi EUPI systems Combined pump-injector assemblies Medium-duty trucks, industrial engines Compact per-cylinder modules, simplifies fuel lines
