Cut-off occurs when the speed\ndecrease or the solenoid valve is de-energized.\nThe first stage gear set sucks the fuel from the line, and the second stage gear set pressurizes\nthe fuel.\nThis unit is supplied for 1-pipe operation, without by-pass plug installed.

Strainer: See technical data\n\nPUMP OPERATING PRINCIPLE Shaft rotation\n and nozzle location\nAs the motor starts, the fuel from the second stage gearset flowing through the cone valve (seen from shaft end)\ncreates a pressure drop across the diaphragm valve. When the pressure difference is A :clockwise rotation/\nsufficient to overcome the spring force, the diaphragm valve closes and the fuel is routed right hand nozzle. (RH-RH)\nto the piston chamber. B : clockwise rotation/\n left hand nozzle.(RH-LH)\nIf the solenoid valve (Normally Open) is :\n C :anti clockwise rotation/\n • Opened (de-energized), the fuel flows through the by-pass channel, no pressure will left hand nozzle.(LH-LH)\n then be built up. The piston will not release the fuel flow through the nozzle. D :anti clockwise rotation/\n • Closed (energized) and the diaphragm valve is closed, the pressure is built up causing right hand nozzle.(LH-RH)\n the piston to open and the fuel flow through the nozzle.\nThe piston spring is adjusted such that a given nozzle pressure can be maintained while\nany resulting excess fuel is dumped.\nWhen the solenoid valve is open (de-energized), the valve opens, closing the piston at full\noperating speed, shutting fuel off the nozzle.

The excess fuel is returned back to the inlet.\nTwo pipe installation :\n Identification number\nThe steel plug of the return port must be removed and the by-pass plug must be inserted\nin the return port allowing excess fuel is bypassed back to the tank. The return plug must B: B6-B100 applications\nnot be reinstalled.\n Revision\nBleed :\nIn one pipe operation, the easy flow bleeder valve must be loosened to bleed the system.\nBleeding in two pipe operation is automatic, but it may be accelerated by loosening the\neasy flow bleeder.\n\n\n Solenoid valve Solenoid valve\n \"closed\" or \"open\" or\n energized position N = Non delay de-energized position\n\n\n\n\n Nozzle port Nozzle port\n Pressure\n adjusting Pressure adjusting\n screw screw\n\n Piston assembly\n Piston assembly\n\n Positive High speed models\n Cone\n strainer to strainer\n valve\n Intake Low speed models\n from tank to seal chamber\n Lip seal\n Second stage High pressure oil\n Gearset\n Easy flow High pressure oil\n To Shaft\n bleed valve\n strainer Low pressure oil\n Diaphragm\n valve\n Return oil\n By-pass plug\n First stage gearset Inlet oil\n Return to tank\n\n Suntec Industries Incorporated - 60 Aberdeen Drive - Glasgow, KY 42141 - USA\n Tel : 270 651 7116 - www.suntecpumps.com\n\f TECHNICAL DATA\n\n General Hydraulic data\n\n Mounting Flange mounting Nozzle pressure range 100 - 150 psi (#2 fuel and lighter)\n 150 - 200 psi (#2 fuel)\n Connection threads\n Inlet 1/4 NPTF Delivery pressure setting 100 psi\n Nozzle outlet 1/8 NPTF\n Pressure gauge port 1/8 NPTF Rated nozzle flow 4 GPH @100 - 150 psi (#2 fuel oil and\n Bleeder valve port 1/8 NPTF lighter fuel)\n 3 GPH @150 - 200 psi (#2 fuel oil)\n Valve function Pressure regulation\n Oil temperature 32 - 140°F\n Cut-off Motor speed dependent\n Ambiant temperature 32 - 140°F\n Strainer open area V = min 3 in 2\n\n Inlet and return pressures 10 psi max.\n NFPA limits pressures to 3 psi max\n Shaft 5/16 in\n\n Suction height Single pipe: 6\" Hg max. vacuum,\n By-pass plug Not inserted in return port, for\n Two-pipe: 17\" Hg max. vacuum, to\n one pipe system.
