FUEL PUMPS
Suntec Series TV Pressure Regulating Valve
(For use with Suntec series ‘T’ pumps)
The TV valve is designed for use with the Suntec series ‘T’ fuel
pumps, see diagrams.
This separate pressure-regulating valve, which is installed in the
nozzle line, is designed to keep constant pressure even if the
output capacity is changed. A built-in dampening device absorbs
vibrations in the valve, effectively eliminating pulsations in the
nozzle line.
Pressure adjustment
Remove the cap nut (1), washer (2) and loosen the locknut (4).
Turning the screw (3) counter-clockwise will decrease the nozzle
line pressure and visa-versa. After adjustment, tighten the locknut
and refasten the washer and cap nut.
OIL PUMP DETAILS
General Notes:
Pump rotation is quoted by the direction of the pump shaft as viewed from the shaft side. The direction
arrow embossed on the face of the pump or pump nameplate is therefore the reverse of the quoted
rotation.
The Oil Pump is completely pre-piped as part of the pumping or pumping and heating set.
Should the Oil Pump performance become suspect then a replacement unit should be obtained and the
Oil Pump returned to determine its serviceability.
Upon replacement refer to the pump bleeding instructions in the section
Pre-firing Checks
on page 15.
Further details regarding the Oil Pump unit can be supplied on request.
