PIUSI BYPASS PANTHER EX56 ATEX-UL Part R24055000

Description

Piusi Bypass Valve Kit for Panther EX56 (ATEX/UL)

Part is original to Piusi.

Product Code: R24055000

The Piusi R24055000 is a genuine OEM replacement bypass valve kit specifically engineered for the Panther EX56 explosion-proof pump series. The bypass valve is a critical internal safety mechanism that allows fuel to recirculate within the pump head when the discharge nozzle is closed while the motor is still running. This prevents over-pressurization of the system, protecting your hoses, seals, and motor from mechanical stress.

Designed to meet the world’s most stringent safety standards, this kit is fully compatible with both ATEX (European) and UL (North American) certified Panther EX models used for transferring flammable liquids.

Key Features & Benefits

• Explosion-Proof System Protection: Precisely calibrated to open at the factory-set pressure limit. This ensures that even during “dead-head” conditions (when the pump is on but the nozzle is shut), the internal pressure remains within the safe parameters required for Class I, Division 1 hazardous locations.
• Dual ATEX/UL Compliance: Manufactured to the exact tolerances required to maintain the global safety certifications of your Panther EX56. Using non-certified internal parts can void your insurance and safety ratings.
• Prevents Motor Overheating: By allowing fluid to move internally during bypass mode, the valve helps dissipate heat, preventing the pump vanes and motor from reaching dangerous temperatures during short periods of inactivity.
• Corrosion-Resistant Internals: Built from high-grade materials designed to withstand constant immersion in Gasoline, Diesel, Kerosene, and Avgas without losing spring tension or sealing integrity.
• Smooth Pressure Regulation: Features a precision-ground plunger and a high-tensile spring that provides a chatter-free transition between dispensing and bypass modes, reducing “water hammer” shock in your fueling lines.
• Genuine Piusi Spare Part: As an authentic Piusi R-Series component, the R24055000 ensures 100% plug-and-play compatibility with the Panther EX56 pump body.

Technical Specifications

If your pump is struggling to reach its rated GPM, or if you notice the motor “straining” excessively when the nozzle is closed, the internal bypass valve may be stuck or the spring may have weakened. A failing bypass valve can lead to blown hoses or burnt-out motor windings. Replacing the assembly with the Piusi R24055000 restores the factory pressure settings and ensures your explosion-proof pump remains a safe, reliable asset for your fueling operation.
