hp-Technik PON6-I-L-3-20 oil pump

The hp-Technik PON6-I-L-3-20 oil pump is a component from the oil pump category, identified by catalogue article 543.520.017 and manufacturer code PON6-I-L-3-20. Parts of this type draw fuel from the tank and deliver it to the nozzle at the pressure that sets the firing rate. An integral solenoid valve gives the sharp cut-off that the burner control demands, which is essential for clean flame extinction at the end of a firing cycle. In an oil burner system, the pump works directly with the oil nozzle, preheater (if fitted for heavier oils), and the burner control that energises the solenoid. The pump also connects to the fuel line in either single-pipe or two-pipe configuration, depending on installation. Selection of a replacement pump of this type depends on rotation direction, pipe arrangement (single or two-pipe), capacity and pressure range, shaft and mounting pattern, and connection thread sizes. A preheater may be required for oils with higher viscosity to ensure proper atomisation, and a filter ahead of the pump protects both the pump and the nozzle from debris. Common failure modes for oil pumps of this class include worn gears that reduce output pressure, weak pressure regulation leading to unstable firing rates, leaking shaft seals that draw air into the fuel, and solenoid coil failure that leaves the burner unable to cut off cleanly, causing post-drip or lockout. When replacing such a pump, always confirm the rotation direction matches the burner fan direction and that the shaft extension and mounting flange align with the coupling and housing. Verify the pressure range covers the burner’s required nozzle pressure and that the solenoid operating voltage matches the burner control output.
