FrancePumps & Compressors

Suntec is a French manufacturer of fuel-oil pumps and combustion-control components, with a product line that has become a reference point in the heating and industrial-burner sectors. The company's engineering focus is on positive-displacement gear pumps, fuel-supply units, and associated valves and switches that regulate the delivery of liquid and gaseous fuels in burner systems. Suntec's pumps are designed for continuous duty in heating installations, process burners, and auxiliary boilers, with models covering a range of displacement capacities, pressure ratings, and electrical configurations. The product families include the AUV series, which is a service pump intended for the replacement market, capable of substituting many one-stage pumps from Suntec's own AS, AL, and ALE lines. The AUV 47L and AUV 47R variants are rated for 220–240 V AC at 50/60 Hz, feature selectable nozzle outlet positions (left or right), and incorporate integrated filtration. These units are specified by their flow curves, which define the relationship between pump speed, pressure, and delivered flow—data that is essential for matching a pump to a specific burner nozzle and combustion chamber. Other pump families include the AE basic model, which has a pressure-regulating valve but no cut-off feature, allowing air purging through the nozzle line; the AP two-step model, which uses a built-in solenoid for two-mode pressure operation; and the AT2, also a two-step model, which adds a blocking solenoid valve with in-line cut-off. For higher-capacity applications, the B-4000 and B-8000 are two-stage, one-step pumps with a high single-pipe lift capacity and a hydraulic dual safety cut-on/off mechanism driven by motor speed and a solenoid bypass valve. These pumps are compatible with a range of fuels, including domestic oil, kerosene, HVO (hydrotreated vegetable oil), and biodiesel blends up to B30, while the B-series also handles #1 and #2 fuel oils and B100. Beyond pumps, Suntec manufactures gas valves, such as the M2N and M3N combined solenoid valves, which are designed for one-stage gas burners and are rated for LPG, natural gas, and hydrogen blends. The company also produces pressure switches, like the Compact F series, which supervise fluid pressure (gas or air) in appliances, with setpoints adjustable via a screw. These components are built to meet industrial standards for safety and reliability, with materials and seals selected for fuel compatibility and long service life. For plant engineers and maintenance managers, Suntec's product range offers a systematic approach to fuel delivery and combustion control, with each component designed to operate within defined pressure and flow envelopes. The availability of technical documentation, including flow curves and model cross-references, supports proper selection and troubleshooting. 3G Electric supplies the full Suntec line, ensuring that procurement teams can source both original equipment and replacement parts for legacy or current burner installations. The catalog includes pumps, valves, switches, and coupling assemblies, allowing maintenance crews to complete field repairs with exact-match components. Whether specifying a new fuel-supply unit or replacing a worn pump in an existing system, the Suntec range provides the technical parameters needed to ensure correct operation, from inlet pressure limits to nozzle outlet configurations. With global shipping, 3G Electric makes these components accessible to industrial facilities worldwide, supporting both routine maintenance and system upgrades.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang Suntec dari 3G Electric.

What is the difference between the Suntec AUV 47L and AUV 47R pumps?

The AUV 47L and AUV 47R are service pumps from Suntec's AUV series, designed for the replacement market. The primary difference is the nozzle outlet position: the 'L' variant has the outlet on the left side, while the 'R' variant has it on the right. This allows the pump to be oriented to match the existing piping layout in a burner. Both models are rated for 220–240 V AC at 50/60 Hz and feature integrated filtration. They are engineered to replace most one-stage pumps, including Suntec's AS 47, AL 35, and ALE 35 references. When selecting between the two, measure the distance from the pump shaft to the nozzle line and choose the variant that aligns with your burner's configuration.

Can Suntec fuel pumps handle biodiesel blends like B30 or B100?

Yes, Suntec fuel pumps are compatible with a range of fuels, but the specific blend depends on the model. The AUV, AE, AP, and AT2 series are listed as compatible with domestic oil, kerosene, HVO, and B30 (a blend of 30% biodiesel). The B-4000 and B-8000 models are rated for #2 fuel oil, #1 fuel oil, and B100 (pure biodiesel). It is important to verify the fuel compatibility for your specific pump model, as seals and materials may differ. For B100 applications, ensure that the pump is rated for that fuel, as higher biodiesel concentrations can affect elastomers and require more frequent maintenance. Always consult the manufacturer's technical data sheet for the exact fuel list.

What is the function of the solenoid valve in Suntec two-step pumps like the AP and AT2?

In Suntec two-step pumps, such as the AP and AT2, the built-in solenoid valve enables two-mode pressure operation. This allows the burner to operate at a low fire rate during ignition or part-load conditions, then switch to high fire for full output. The solenoid is energized to change the pressure setting, which in turn changes the fuel flow to the nozzle. The AT2 model also incorporates a blocking solenoid valve with an in-line cut-off function, which stops fuel flow when the burner shuts down, preventing drips and ensuring clean shutdown. This is particularly useful in applications where precise control of combustion is required for efficiency and safety.

How do Suntec B-4000 and B-8000 pumps achieve high single-pipe lift capacity?

The B-4000 and B-8000 are two-stage, one-step pumps that use a two-stage gear set to achieve high single-pipe lift capacity. The first stage gear set sucks fuel from the tank, while the second stage pressurizes it for delivery to the nozzle. This design allows the pump to lift fuel from depths that would be difficult for single-stage pumps, making them suitable for installations where the fuel tank is located below the burner. Additionally, these pumps feature a hydraulic dual safety cut-on/off mechanism driven by a motor speed-dependent device and a solenoid bypass valve. This ensures that fuel flow is cut off if the motor speed drops or if there is a loss of power, enhancing safety.

Are Suntec gas valves like the M2N and M3N suitable for hydrogen blends?

Yes, the Suntec M2N and M3N combined gas valves are designed to be adapted to every type of one-stage gas burner and are compatible with LPG, natural gas, and hydrogen blends (H2 Blend). These valves consist of two Class A solenoid valves in series, providing redundant safety shut-off. The 'M2N' and 'M3N' designations refer to different configurations, likely varying in connection size or flow capacity. When using hydrogen blends, it is crucial to verify that the valve's materials and pressure ratings are appropriate for the specific blend percentage, as hydrogen can affect certain metals and seals. Always check the manufacturer's specifications for the maximum hydrogen content allowed.

What is the purpose of the Suntec Compact F pressure switch?

The Suntec Compact F pressure switch is designed to supervise fluid pressure, either gas or air, in appliances such as burners. It operates by monitoring the pressure and providing a signal when the pressure falls below or rises above a setpoint. The pressure value is settable through the position of a screw, allowing the user to adjust the switch to the desired threshold. This is commonly used to ensure that the combustion air supply is adequate before ignition, or to detect blockages in gas lines. The switch is compatible with LPG, natural gas, and hydrogen blends, making it versatile for various burner applications.
