Gear Pump

OIL PUMP TYPE AN GEAR SIZES 47-57-67-77-97

This is a general specification leaflet; for specific applications not
covered herein, contact Suntec.
The SUNTEC AN oil pump is the basic model incorporating a pressure regulating
valve with cut-off. 

APPLICATIONS

 - Light oil, B10 heating oil/biofuel blend (as defined in DIN V51603-6) and
kerosene. 

- One or two-pipe system. 

- Normally associated with in-line solenoid valve.

 PUMP 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 which does not go through the nozzle line will be by-passed through the
valve back to the return line, in a two pipe installation or, if it is a one-pipe
installation, back to the suction port in the gear-set; in that case, the by-pass
plug must be removed from the return port, and the return port sealed by steel
plug and washer. 

The valve also has a cut-off function as follows :
During starting period when the gear-set speed is increasing, all the oil passes
through a special flat on the piston, back to the return.
