    Suntec AP Pumps

    The Suntec AP Series of pump are a light oil pump designed for use on a 1 or 2 pipe system. Suntec AP pumps have built in solenoids allowing a high or low pressure supply through the same nozzle. 

    High Pressure Mode

    This is actuated with the solenoid valve activated (ie. closed); activating this solenoid valve closes the by-pass channel to the return. Oil is then transferred to the nozzle line at the pressure given by the high pressure regulating valve.

    Low Pressure Mode

    The low pressure actuates with the solenoid valve open (ie. non activated); the by-pass channel is open, the oil is supplied to the nozzle line via the by-pass hole and the low pressure adjustment is made by the screw on the solenoid tube. It is preferable to set the high pressure given by the pump valve (with solenoid activated) before the low pressure, with solenoid non activated.

    Please Note

    Care should be taken not to overtighten the low pressure adjusting screw of the solenoid tube, as this may eliminate the low pressure range. For two pipe installation, the by-pass plug fitted in the return port allows any oil not required at the nozzle to be dumped back to the tank. For one pipe installation, the by-pass plug must be removed and the return port plugged, oil which is not required at the nozzle is then returned back to the suction port in the gear set.


    Rotation of these pumps is determined by viewing the pump from the shaft end.

    Pump Options
