Nozzle Port: Right
Shaft Diameter: 11mm
The SUNTEC E 1001 oil pump incorporates a pressure regulating valve with cut-off function. Its design is basically similar to that of J pumps, but E pumps can also be used with kerosene and heavy oil.
- Light oil, B10 heating oil/biofuel blend (as defined in DIN V51603-6), medium and heavy oil.
- 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 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 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.
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. Once the speed reaches a certain value and the flow can no longer pass through this flat, then the pressure increases rapidly overcoming the valve spring force and opens the valve.
Bleeding in two pipe operation is automatic, but it may be accelerated by loosening the plug in a pressure gauge port.
In one pipe operation, a pressure port must be opened to bleed the system.
