hp-Technik 12/14 coupling
This coupling connects the burner motor to the oil pump shaft. It transmits the rotational drive from the motor to the pump while accommodating minor angular or parallel misalignment between the two shafts. Such couplings typically consist of two metal hubs and an elastomeric insert that absorbs vibration and protects the pump from shock loads. In oil burners, a worn or damaged coupling can cause the pump to run unevenly, reduce oil delivery, or generate noise. When selecting a replacement coupling of this type, the main considerations are the shaft diameters of the motor and pump, the keyway dimensions, and the overall length of the coupling assembly. The elastomeric insert should be inspected for cracks, hardening, or oil contamination, as these indicate that the coupling needs renewal. No specific dimensions or compatibility details are listed for the hp-Technik 12/14 coupling beyond the supplier codes provided in the catalogue entry.
