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.
