Suntec E6 ND 1001 - 1 Stage Oil Pump - 11mm shaft
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.
Suntec E6 ND 1001 Oil Pump Features
- Light oil, B10 blend, medium and heavy Oil
- 1 or 2 pipe operation
- 1 Stage
- Anti-clockwise rotation
- Normally assosiated with in-line solenoid valve.
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.
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. 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.
During the stop sequence, the gear-set speed slows down and the valve closes when the gear-set capacity is lower than the flat flow. The cut-on and cut-off speeds depend on the gear-set size and set pressure
