★ Brand: SUNTEC.

★ Origin Country: France.

★ The SUNTEC J oil pump is for medium capacity oil burners from 400 to 3000kW. It incorporates a pressure regulating valve and is available with or without cut-off function.

★ 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.

★ Models 1000 & 1001, 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. Models 1002 & 1003 have no cut-off function. Cut-off must be provided by an external solenoid valve.

One Step Model

★ Brand: SUNTEC.

★ Origin Country: France.

★ The SUNTEC AT3 oil pump offers 2 mode pressure operation, in-line cut-off function, plus a special hydraulic outlet on the cover featuring nozzle pressure during high mode and dumping during low mode.

★ 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.

★ Switching between low and high pressure is assured by a “normally open” by-pass solenoid valve. When this solenoid is non-activated, a by-pass channel is open, allowing the normal functioning of the low-pressure valve which sets the nozzle pressure. When this solenoid is activated, the by-pass channel is closed, thus pressure will build up on both sides of the low-pressure valve eliminating its effect, and the high-pressure valve now determines the nozzle pressure.

★ The blocking solenoid valve of the nozzle line is of the “normally closed” type. This design ensures extremely fast response and the switching can be selected according to the burner operating sequence and is independent of motor speed. When this solenoid is non-activated, the valve is closed and all oil pressurized by the gear set passes through the regulators to suction or to the return line, depending upon pipe arrangement.

★ As soon as this solenoid is activated, oil passes to the nozzle line at the pressure set by the pressure regulating valves.

★ In two pipe operation, the by-pass plug must be fitted in the return port, which ensures that the oil dumped by the regulating valves is returned to the tank and the suction line flow is equal to the gear set capacity. Bleeding in two pipe operation is automatic (it is assured by a bleed flat on the pistons), but it may be accelerated by opening a pressure port.

★ In one pipe operation, the by-pass plug must be removed, and the return plugged. Oil which is not required at the nozzle is returned directly to the gear inlet via the pressure regulating valves, and the suction line flow is equal to the nozzle flow.

★ A pressure port must be opened to bleed the system.

One Step Model

★ Origin Country: France.

★ 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. 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 solenoid valve of the AS pump is of the “normally opened” type. When the solenoid valve is non-activated, the by-pass channel between the pressure and return sides of the valve is open. No pressure will then be built up to open the valve; it does not matter which speed the gear set has. When the solenoid is activated, this by-pass channel is closed and because of the full speed of the gear set, the pressure necessary to open the valve will be built up very rapidly, which gives a very sharp cut-on function.

Basic MODEL

★ Brand: SUNTEC.

★ Origin Country: France.

★ The SUNTEC AN oil pump is the basic model incorporating a pressure regulating valve with cut-off.

★ 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. 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.

★ The SUNTEC AL oil pump incorporates a blocking solenoid valve with in-line cut-off function.

★ 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. A pressure regulating valve is used to dump all oil which is not required at the nozzle.

★ In two-pipe operation, the by-pass plug must be fitted in the return port, which ensures that the oil dumped by the regulating valve is returned to the tank and the suction line flow is equal to the gear set capacity.

★ In one-pipe operation, the oil which does not go through the nozzle line is returned directly to the gear inlet and the suction line flow is equal to the nozzle flow. In that case, the by-pass plug must be removed from the return port, and the return port sealed by steel plug and washer.
