Page 25: Suntec Pumps As 47
SUNTEC PUMPS AS 47 - 57 - 67 Operating principle The gear set draws oil from the tank through the built-in filter and transfers it to the valve that regulates the oil pressure to the nozzle line. All oil that does not go through the nozzle line will be dumped through the valve back to the return line in two pipe installation or, if it is a one-pipe installation, back to suction port in the gear set . -
Page 26: Delta Vm Pumps
DELTA VM PUMPS In the VM series of DELTA pumps the pressurised flow of oil P is shut off by a built in solenoid and may therefore be switched on for startup of the motor pre-purge) or off before the motor itself switches off (flame goes out instantly when the spray from the nozzle stops). Oil pressure is regulated and kept constant by the piston valve which is activated when the light comes on to signify that the oil discharged exce- eds nozzle capacity and is being returned to the tank (twin-pipe system) or being returned to the suction pipe through a bypass in the pipe (sin- gle-pipe system). -
Page 27: Suntec At2 Pump
SUNTEC AT2 PUMP The SUNTEC AT2 oil pump features 2 mode pressure operation and incorporates a blocking solenoid valve with in-line cut-off function. Switching between low and high modes is assured by a 2nd integral solenoid valve. Operation The gear set draws oil from the tank through the built-in filter and transfers it to the nozzle line via the cut-off solenoid valve. Pressure regulation is assured by two spool valves, one for each pressure mode. -
Page 28: Notes For Use And Maintenance Of Fuel Pumps
NOTES FOR USE AND MAINTENANCE OF FUEL PUMPS Make sure that the by-pass plug is not used in a single pipe installation, because the fuel unit will not function properly and damage to the pump and burner motor could result. Do not use fuel with additives to avoid the possible formation over time of compounds which may deposit between the gear teeth, thus obstructing them. - Page 29 APPENDICX: COMPONENTS CHARACTERISTICS...
