hp-Technik PMG-1604-1-L-2-20-So pompa a motore a olio

The hp-Technik PMG-1604-1-L-2-20-So is an oil motor pump listed under catalogue article 543.526.024 and manufacturer code 2360004. It belongs to the oil pump stations category. 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, preventing after‑drip and ensuring clean shutdown. Such oil pumps are selected by rotation direction (clockwise or counter‑clockwise as viewed on the shaft), single‑ or two‑pipe operation, capacity and pressure range, shaft and mounting pattern, and connection thread sizes. In applications using heavier oil grades, a preheater is often included to reduce viscosity for proper atomisation; an integrated or in‑line filter protects the pump and nozzle from contamination. When replacing a pump of this class, the installer must match these parameters exactly to the burner design, because an incorrect shaft rotation or pressure setting will prevent the burner from reaching its rated output or may cause unstable operation. Common failures in oil pumps of this type include worn gears that reduce delivery pressure, a weakened pressure regulator that cannot hold the set value, shaft seal leakage, and solenoid coil failure that leaves the burner unable to cut off cleanly. Before ordering a replacement, checking the existing pump’s marking for rotation and pipe arrangement is essential; the solenoid coil resistance can be measured to confirm compatibility with the burner control’s output.
