In that case the by-pass plug must be removed right hand nozzle.\nfrom the return port and the return port sealed by steel plug and washer.\n D V 57 C 7 2 xx 3 P\nBleed\nBleeding in two pipe operation is automatic.\nIn one pipe operation, during the starting period, air is purged through the nozzle Pump series\nline : the by-pass hole of the nozzle plug allows air to pass to the nozzle line without\nopening of the regulator valve. 2 : hub Ø 54 mm\n 3 : hub Ø 32 mm\nFor the first start up, bleeding can be accelerated by loosening the plug in a pressure\ngauge port. Model number\nNote Revision number\nOwing to the presence of the nozzle by-pass hole, the pump has no cut-off function.\n Installation\nCut-off must be provided by an external solenoid valve. P : by-pass plug inserted in return port\nModels gear sizes \"45\" and \"55\" have a piston with a bleed slot to avoid build up of for two-pipe operation.\n M : without by-pass plug,\npressure in the nozzle and suction lines during shut down due to the expansion of\n return port sealed by steel plug\noil caused by nozzle line heaters. for one-pipe operation.\n\n\n\n\n Oil under suction\n Pressure\n adjustment To nozzle\n Oil under pressure\n\n By-passed oil\n Shaft seal By-pass hole\n returned to tank,\n or to suction\n\n Back Pressure\n to suction Gear set\n gauge port\n\n\n Vacuum\n gauge port\n By-pass\n By-pass plug\n plug inserted\n removed\n Return\n plugged\n ONE PIPE TWO PIPE Return Inlet\n INSTALLATION INSTALLATION\n\n\n\n\n SUNTEC INDUSTRIES FRANCE - 1, rue Lavoisier - CS 60 102 - F-21603 LONGVIC Cedex - www.suntec.fr\n\fTECHNICAL DATA Pump capacity\n Capacity (L/h)\n\n\nGeneral\n\nMounting Flange or hub 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 1/4 or G 1/8\n Pressure (bars)\nValve function Pressure regulating without cut-off\nStrainer Open area : 12 cm2 Viscosity = 20 cSt - Rated speed = 2850 rpm\n\n Opening size : 530 µm\n Capacity (L/h)\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\nWeight 1,8 - 1,9 kg (depending on the model)\n\n\n\n\nHydraulic data\n\nNozzle pressure range 10 - 28 bars Pressure (bars)\n(other ranges available on request, refer to the specified range of the particular fuel\n Viscosity = 75 cSt - Rated speed = 2850 rpm\nunit)\n Data shown take into account a wear margin.\nFactory setting 14 bars Do not oversize the pump when selecting the gear capacity.\nOperating viscosity 2 - 75 mm²/s (cSt)\n Power consumption\n (Higher viscosity oil can be used by feeding the pump or by\n Power (W)\n heating the oil to lower its viscosity under 75 cSt)\nOil temperature 0 - 90°C in the pump\nInlet pressure 2 bars max.\nReturn pressure 2 bars max.\nSuction height 0,45 bars max. vacuum to prevent air separation from oil\nRated speed 3600 rpm max.\nTorque (@ 45 rpm) 0,10 N.m (D 45/47/55/57)\n 0,12 N.m (D 67)\n\n\n\n\n Pressure (bars)\n\n Viscosity = 20-75 cSt - Rated speed = 2850 rpm\n\n\n PUMP DIMENSIONS (in mm) Examples show \"C\" rotation and nozzle outlet.\n\n Hub mounting Flange mounting\n 41 39 42 58 41 51 42 58\n\n \n \n A…
