IDENTIFICATION\nThe SUNTEC AJ oil pump is the basic model incorporating a pressure regulating\n (Not all model combinations are available\nvalve with cut-off*. Consult your Suntec representative)\n AJ : pressure regulation\nCOMPATIBILITY\n V : B100 applications\n- Domestic oil, HVO, B100 (biofuel blend with the addition of 100% FAME, as\ndefined in DIN SPEC 51603-6), kerosene.

Shaft rotation\n and nozzle location\n (seen from shaft end)\nPUMP OPERATING PRINCIPLE A : clockwise rotation/\n right hand nozzle.\nThe gear set draws oil from the tank through the built-in filter and transfers it to B : clockwise rotation/\nthe valve that regulates the oil pressure to the nozzle line. All oil that does not go left hand nozzle.\n C : anti clockwise rotation/\nthrough the nozzle line will be by-passed through the valve back to the return line in left hand nozzle.\ntwo pipe installation or, if it is a one-pipe installation, back to the suction port in the D : anti clockwise rotation/\ngear-set; in that case, the by-pass plug must be removed from the vacuum gauge right hand nozzle.\nport and the return port sealed by steel plug and washer. Pressure range\n B : 7 - 15 bars\nThe valve also has a cut-off function* as follows : C : 10 - 20 bars\n E : 10 - 28 bars\nDuring starting period when the gear-set speed is increasing, all the oil passes A : 0,5 - 3 bars\nthrough a bleed slot in the piston, back to the return. Once the speed reaches K : kerosene\na certain value and the flow can no longer pass through this bleed slot, then the applications\npressure increases rapidly overcoming the valve spring force and opens the valve.\n AJ V 4 C B K 1000 4 P\nDuring the stop sequence, the gear-set speed slows down and the valve closes\nwhen the gear-set capacity is lower than the bleed slot flow.\n 1000 : standard model with\nThe cut-on and cut-off speeds depend on the gear-set size and set pressure. cut-off function\nBleed Ø 11 mm shaft\n 1002 : by-pass nozzle,\nBleeding in two pipe operation is automatic, but it may be accelerated by loosening no cut-off function\nthe plug in a pressure gauge port. Ø 11 mm shaft\n 1003 : standard model with\nIn one pipe operation, a pressure port must be opened to bleed the system. cut-off function\n Ø 8 mm shaft\n*Owing to the presence of the nozzle by-pass hole, AJ 1002 models have no cut-off\nfunction. Cut-off must be provided by an external solenoid valve.
