Water, oil and fuel pumps
Emporio Rossi sells water, oil and fuel pumps of the following brands:
- OMP
- BCD
- BOSCH
There are different pumps in a truck:
- Water pumps, that are necessary to pump the water coolant in the engine.
- Oil pumps, that are needed to guarentee the lubrication of the engine and other parts of the drivetrain.
- Fuel pumps, that give the engine its necessary fuel
The main brand in first choice water pumps is OMP.
There are two kinds of oil pumps: mechanical or electrical ones.
Mechanical pumps are driven directly by the engine, while electrical pumps are controlled by an ECU.
Gear pumps: here there are two gears, engaged one into the other, with one driving the other. The fluid is carried by the gears from the intake to the discharge side of the pump, where the meshing of the gears displaces the fluid.
Trochoid pumps: two cogged rotors are used, the axis of the inner rotor is slightly offset from the axis of the outer rotor and this permits the pumping of the oil. These pumps moves a similar amount of oil, if compared to gear pumps, but they are much smaller .
Piston pumps: adopted on old vehicles, or in the case a second regolation, beside the speed control, is needed.
