Pompa Suntec A2L – Model dua langkah

[{"filename":"A2L_EN_Ed15_April-2024.pdf","text":"PUMP TYPE A2L A2L\n A2L - 11 - Ed 15 - April 2024\nThis is a general specification leaflet ; for specific applications not covered herein,\n PUMP\ncontact Suntec.\n IDENTIFICATION\n (Not all model combinations are available\nThe SUNTEC A2L oil pump has two nozzle outlets. It incorporates two blocking solenoid Consult your Suntec representative)\nvalves with in-line cut-off function, one for each nozzle outlet.\n A2L : 2 nozzle outlets\nCOMPATIBILITY\n V : B100 applications\n- Domestic oil, HVO, B100 (biofuel blend with the addition up to 100% FAME, as\n Gear set capacity\ndefined in DIN SPEC 51603-6 and EN 14214), kerosene. (see pump capacity curves)\n- Two nozzle outlets.\n- Two independent blocking solenoid valves. Shaft rotation and\n pressure regulation location\n- A sole regulator for both nozzle lines. (seen from shaft end)\n A : clockwise rotation\nPUMP OPERATING PRINCIPLE left hand regulation\n B : clockwise rotation\nThe gear set draws oil from the tank through the built-in filter and transfers it to the nozzle right hand regulation\nlines via the cut-off solenoid valves. A pressure regulating valve is used to bypass all oil C : anti-clockwise rotation\nwhich is not required at the nozzles. right hand regulation\nIn two-pipe operation, the by-pass plug must be fitted in the return port, which ensures D : anti-clockwise rotation\n left hand regulation\nthat the oil bypassed by the regulating valve is returned to the tank and the suction line\nflow is equal to the gear set capacity. K : kerosene applications\nIn one-pipe operation (by-pass plug removed and return plugged), the oil which does Pump series\nnot go through the nozzle lines is returned directly to the gear inlet and the suction line 7 : hub Ø 32 mm\nflow is equal to the sum of the 2 nozzle flows. Model number\nBleed A2L V 35 C K 9 7 xx 4 P 07 00\nBleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston. Revision number\nIn one-pipe operation, the plug of a pressure gauge port must be loosened until the air\nis evacuated from the system. Installation\n P : by-pass plug inserted\nCut-off for two-pipe operation\nThe solenoid valves of the A2L pump are of the \"normally closed\" type. Each solenoid M : by-pass plug removed\n and return plugged\nvalve is situated in one nozzle line. This design ensures extremely fast response and for one-pipe operation\nthe switching can be selected according to the burner operating sequence and is\nindependent of motor speed. Solenoid valve voltage\n 05/07 : 220-240 V AC - 50/60 Hz\nWhen the solenoids are non-activated, the valves are closed and all oil pressurized by 06 : 110-120 V AC - 50/60 Hz\nthe gear set passes through the regulator to suction or to the return line, depending 02 : 24V AC - 50/60 Hz\nupon pipe arrangement. Connector cable length\nAs soon as the solenoids are activated, oil passes to the nozzle lines at the pressure 00 : no cable\nset by the pressure regulating valve. 35 : 35 cm cable - 45 : 45 cm cable\nThe two solenoid valves can be operated independently. 60 : 60 cm cable - 10 : 1 m cable\n\n\n\n\n Solenoid valve 2 Solenoid valve 1\n (NC) Solenoid valve 2 Solenoid valve 1 (NC)\n closed (NC) (NC) closed\n open open\n\n\n\n\n to nozzle 2 to nozzle 1\n Pressure\n gauge port\n\n\n Shaft seal Back to\n Pressure suction\n adjustment Pressure\n Oil under suction Gear set gauge port\n\n\n Oil under pressure Vacuum\n gauge port\n By-pass\n By-passed oil plug\n returned to tank, removed\n or to suction By-pass\n TWO PIPE Suction Return ONE PIPE Return\n plug\n INSTALLATION inserted\n INSTALLATION plugged\n\n\n SUNTEC INDUSTRIES FRANCE - 1, rue Lavoisier - CS 60 102 - F-21603 LONGVIC Cedex - www.suntec.fr\n\fTECHNICAL DATA Pump capacity\nGeneral Capacity (L/h)\n\nMounting Hub mounting according to EN 225\nConnection threads cylindrical according to ISO 228/1\nInlet and return G 1/4\nNozzle outlet G 1/8\nPressure gauge port G 1/8\nVacuum gauge port G 1/8\nValve function Pressure regulation\nStrainer Open area : 6 cm2 (A2L 35/35K/55/55K/65/65K)\n 20 cm2 (A2L 75/75K/95/95K)\n Opening size : 150 µm\nShaft Ø 8 mm according to EN 225\nBy-pass plug inserted in return port for two-pipe system ;\n to be removed with a 4 mm Allen key for one pipe system.
