PUMP\nThe SUNTEC ALE oil pump incorporates a blocking solenoid valve fitted with a built- IDENTIFICATION\nin return valve ensuring an in-line cut-off function and a nozzle line pressure relief.\nThe integration of the return valve into the solenoid valve means that the ALE pump (Not all model combinations are available\nperformance and dimensions are identical to the AL pump.

A pressure regulating valve is used to location (seen from shaft end)\ndump all oil which is not required at the nozzle. A : clockwise rotation/\nIn two-pipe operation, the by-pass plug must be fitted in the return port, which right hand nozzle.\nensures that the oil by-passed by the regulating valve is returned to the tank and B : clockwise rotation/\nthe suction line flow is equal to the gear set capacity. left hand nozzle.\n C : anti clockwise rotation/\nIn one-pipe operation, the oil which does not go through the nozzle line is returned directly left hand nozzle.\nto the gear inlet and the suction line flow is equal to the nozzle flow. In that case, the D : anti clockwise rotation/\nby-pass plug must be removed from the return port, and the return port sealed by right hand nozzle.\nsteel plug and washer.\n K : Kerosene applications\nBleed Pump series\nBleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston.\n 3 : hub Ø 32 mm\nIn one-pipe operation, the plug of a pressure gauge port must be loosened until the\nair is evacuated from the system.
