ding to the indicated delivery value.
How to check injection pump delivery valve sealing
Components:
1 Valves
2 Seat
Adjust pump rack at half-stroke.
Turn ywheel according to its direction of rotation so that the plunger
puts the circuit under pressure.
During this operation the displayed pressure will gradually reach a peak
followed by a sudden drop which corresponds to valve closing.
Pressure drop should be 30÷50 bar.
Replace the valve if pressure drop is below this value.
Repeat the same operation for the other plunger.
