In-line injection pump
The in-line injection pump has the same number of pumping sections as the number of engine cylinders. It consists of: a regulator, a clock and a supply pump mounted on the body. It is mainly used for construction machines as well as medium and large trucks.
Rotary injection pump
The electronic control system of this type of pump consists of various sensors, an electronic control unit (ECU) and an actuator. Signals are sent to the Ecu by sensors that detect the engine's operating status. The actuator controls the size and injection time based on the ECU signals which calculates the corresponding values.
Distributor injection pump
The distributor injection pump has a distributor that transfers the compressed fuel, according to the order of injection, to each of the cylinders, and therefore has only one delivery section, regardless of the number of cylinders. All parts are designed within the pump housing. This type of pump, due to its dimensions, is ideal for small engines.
Common Rail pump
The pump, e.g. BOSCH has 3 pumping sections. The fuel flow adjustment takes place on the high pressure side. Part of the compressed fuel is directed by opening the high pressure valve back to the tank. The maximum pressure is 135 MPa.
What are the signs of damaged diesel pumps?
What does the reconditioning process look like?
Delivery of diesel pump to remanufacture or test
Replacement of worn components (after very accurate analysis by means of a specialised microscope )
adjustment of assembled parts and testing
Shipment of remanufactured diesel pump
Why it’s worth remanufacturing?
Increased engine power
What are the signs of damaged injectors, injection pumps or turbochargers?
Difficulties with starting
Black or white exhaust smoke
No reaction from the accelerator pedal
Increased fuel consumption
Louder operation of components
