IDENTIFICATION\nThe SUNTEC J oil pump is for medium capacity oil burners from 400 to 3000kW. (Not all model combinations are available.\n Consult your Suntec representative)\nIt incorporates a pressure regulating valve and is avalaible with or without cut-off\nfunction. J : Pressure regulation\n\nCOMPATIBILITY Gear set capacity\n (see pump capacity curves)\n- Light and medium oil, HVO, B100 (biofuel blend with the addition up to Strainer\n100% FAME, as defined in DIN SPEC 51603-6 or EN 14214). For kerosene\n Shaft rotation\napplications, contact Suntec. and nozzle location\n- One or two-pipe system. (seen from shaft end)\n- Normally associated with in-line solenoid valve. A : clockwise rotation/\n right hand nozzle.\nPUMP OPERATING PRINCIPLE B : clockwise rotation/\n left hand nozzle.\n C : anti clockwise rotation/\nThe gear set draws oil from the tank through the built-in filter and transfers it to\n left hand nozzle.\nthe valve that regulates the oil pressure to the nozzle line. All oil that does not go D : anti clockwise rotation/\nthrough the nozzle line will be dumped through the valve back to the return line in right hand nozzle.\ntwo pipe installation or, if it is a one-pipe installation, back to the suction port in the Pressure range\ngear-set. In that case, the by-pass plug must be removed from the return port and\nthe return port sealed by steel plug and washer.\nModels 1000 & 1001, the valve also has a cut-off function as follows :\n - During starting period when the gear-set speed is increasing, all the oil passes J 6 P A C 1001 8 P\n through a special flat on the piston, back to the return. Once the speed reaches a\n certain value and the flow can no longer pass through this flat, then the pressure 1000 : conical connection threads\n cut-off function\n increases rapidly overcoming the valve spring force and opens the valve. 1001 : cylindrical connection threads\n - During the stop sequence, the gear-set speed slows down and the valve closes cut-off function\n when the gear-set capacity is lower than the flat flow. 1002 : cylindrical connection threads\n by-pass nozzle, no cut-off function\nThe cut-on and cut-off speeds depend on the gear-set size and set pressure. 1003 : conical connection threads\n by-pass nozzle, no cut-off function\nModels 1002 & 1003 have no cut-off function. Cut-off must be provided by an\nexternal solenoid valve.
