What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

This coupling motor-pump (SKU 537D8154) is an original ACV connecting element for ACV heating equipment. It measures 17 mm by 13 mm by 13 mm and uses a flexible element or rigid insert to connect the burner motor shaft to the oil pump drive. The coupling provides a tight seal and transmits torque so the pump delivers fuel to the nozzle. It is designed to fit ACV BMR31 burners and other ACV heating equipment.

Further details

Application class	oil-fired burner coupling; connects motor shaft to oil pump drive
Function	connects burner motor shaft to oil pump drive, transmitting torque
Material properties	resistance to heat transfer fluid, temperature fluctuations, and operating pressure
Primary failure mode	pump erratic operation, unstable oil pressure, poor combustion
Resistance to	heat transfer fluid, temperature fluctuations, and operating pressure
Synchronous operation	ensures synchronized motor-fan-pump operation without slippage

Choosing and fitting

Parts of this type are selected by matching the motor and pump shaft diameters, the centre distance between them, and the coupling form (jaw, splined, or pin-and-bush). The material and torque rating must suit the pump’s operating pressure and the motor’s power. Before ordering, compare the physical dimensions with the original part; during installation, verify that the coupling aligns freely without forcing and that the pump rotates smoothly after reassembly.

Signs of failure

Couplings of this kind wear, crack, or lose their flexible element, causing the pump to run erratically, unstable oil pressure, and poor combustion. Damage can also produce noise or vibration. Check the coupling for cracks, deformation, and free play, and confirm that the pump rotates smoothly after reassembly.
