The Wacker Neuson Lock Cam is a genuine OEM component designed for the HP252, BP45 Pureheat Booster Pump, and Pureheat Hydronic Heater series — including oil burner, gas burner, and diesel-fired configurations. As a direct OEM replacement, this part is sourced to the exact specification used in original production, ensuring a proper fit within the heating and fluid-circulation systems it serves. Compatible across the full Pureheat hydronic heater lineup, the is the correct part for both oil and gas burner variants as well as the Hydronic Air Heater diesel models. Keep a verified part number on hand to avoid fitment guesswork during service.
Key Features
- Genuine OEM Locking Integrity — Manufactured to the exact cam profile and material spec used at the factory, ensuring the locking action engages and releases as intended without slop or misalignment.
- Direct Drop-In Replacement — Matches the original mounting geometry and connection points on Pureheat hydronic heater assemblies, allowing straightforward swap-out during scheduled service or emergency repair.
- Broad Pureheat Series Coverage — A single part number that fits the HP252, BP45 Pureheat Booster Pump, Pureheat Hydronic Heater (oil and gas burner), and Hydronic Air Heater (diesel) models.
- Maintains Secure Component Connection — A worn or fatigued lock cam can allow connected components to shift or disengage under operational vibration, interrupting fluid flow or burner function; a fresh OEM cam restores positive retention.
- Fuel System Integrity — In hydronic heating applications, a properly functioning lock cam keeps fuel and fluid line connections secure, which is critical to safe and consistent burner operation.
A lock cam is a mechanical fastening component that uses a rotating or eccentric profile to clamp, secure, or release an adjoining part with a partial turn rather than a threaded connection. In hydronic heater systems like the Pureheat lineup, lock cams are typically used to secure hose fittings, panel assemblies, or fluid-circuit connections in a way that allows quick disconnection during service while holding firmly under normal operating conditions. When a lock cam wears, chips, or loses its spring tension, the connection it holds can work loose — leading to leaks, disconnected assemblies, or interrupted heater operation that requires a full shutdown to diagnose and correct.
