Suntec Burner Fuel Pump in Nairobi | Wisdo Merchants

Suntec Burner Fuel Pump for Diesel and Kerosene Burners

The fuel pump is the heart of an oil burner. It draws diesel from the tank and raises it to the pressure the nozzle needs to spray a fine mist. A worn pump gives low pressure, a smoky flame, hard starts and lockouts. A genuine Suntec burner fuel pump restores clean, steady combustion. At Wisdo Merchants, we stock the Suntec AS47A, AS47C and AS67C for boiler technicians, bakeries, hotels, laundries and factories across Nairobi and Kenya.

An oil burner relies on the pump to deliver fuel at a precise pressure. Inside the Suntec AS, a gear set draws the oil in and a pressure regulator holds the nozzle pressure steady. A built-in solenoid valve then opens and closes the nozzle line instantly. As a result, the burner lights cleanly and cuts off sharply, without dripping.

Features and Benefits of the Suntec Burner Fuel Pump

• Steady nozzle pressure. The built-in regulator keeps pressure constant for a clean, efficient flame.
• Built-in solenoid valve. It gives a sharp start and a clean, drip-free cut-off when the burner stops.
• Adjustable pressure. You can set the nozzle pressure to match the burner and nozzle.
• One-pipe or two-pipe. It works with either fuel line layout.
• Three models in stock. Choose the AS47A, AS47C or AS67C to match your burner’s rotation, nozzle side and output.

For technicians, this means fast, reliable repairs with a trusted brand. Meanwhile, owners get dependable heat, cleaner combustion and less fuel waste.

Applications of the Suntec Burner Fuel Pump and How to Use It

• Diesel burners on hot water and steam boilers
• Bakery and industrial ovens
• Dryers, furnaces and air heaters
• Domestic and light commercial heating burners
• Replacing worn or noisy burner pumps during servicing

Replacing a Worn Burner Pump

Picture a technician called to a hotel boiler whose burner keeps locking out with a smoky flame. First, they read the code on the old pump’s label, then switch off and isolate the burner. Next, they close the fuel valve, disconnect the fuel lines and remove the old pump from the burner. After that, they fit the matching Suntec pump, checking the rotation and nozzle side are the same, and reconnect the suction, return and nozzle lines. Finally, they bleed the air, fit a pressure gauge, set the nozzle pressure to the burner’s specification, and check the flame.

Burners and Spares It Works With

The Suntec AS series is a common pump on domestic and light commercial diesel burners. To confirm the right model, match the code on your existing pump. While servicing burners like the Riello G5 for small boilers or the Baite BT14 compact burner, also replace worn lines with our braided hose for burner fuel lines. For accurate boiler temperature control, fit our stainless steel PT100 boiler sensor.

Safety and Handling

• Isolate first. Switch off the burner and close the fuel valve before removing the pump.
• Match the model. The wrong rotation or nozzle side means the pump won’t deliver fuel.
• Set pressure with a gauge. Adjust nozzle pressure only with a gauge fitted, and stay within the burner’s specification.
• Don’t run it dry. Bleed the air promptly, since running without oil wears the gears.
• Mind the plug. For one-pipe systems, remove the internal bypass plug. For two-pipe systems, leave it in place. Fitting it wrongly can damage the pump.
• No naked flames. Keep sparks and flames away from fuel lines and spills.

Frequently Asked Questions

What is the difference between AS47A and AS47C?

Both have the same gear size and output. The AS47A turns clockwise with a right-hand nozzle outlet. The AS47C turns anticlockwise with a left-hand nozzle outlet. Match the letter on your old pump.

When do I need the AS67C instead of an AS47?

The AS67 has a larger gear set, so it delivers more fuel for higher-output burners. It also has a higher pressure range of 10 to 15 bar.

How do I know my burner pump is failing?

Common signs are low or unsteady nozzle pressure, a smoky or unstable flame, noisy running, leaks, or repeated lockouts.

Can it run on kerosene?

The standard AS works on light oil (diesel) and on kerosene within its viscosity range. Suntec also makes dedicated “K” kerosene versions, so check with us if kerosene is your main fuel.
