PIUSI SHAFT SEAL PANTHER EX ATEXUL Part R24012000

Description

Piusi Shaft Seal for Panther EX (ATEX/UL)

Part is original to Piusi.

Product Code: R24012000

The Piusi R24012000 is a high-specification, genuine OEM replacement mechanical shaft seal designed specifically for the Panther EX series of explosion-proof pumps. As a critical safety and performance component, this seal sits between the pump’s hydraulic chamber and the electric motor, preventing flammable liquids and vapors from escaping the “wet end” of the pump.

Engineered to meet the rigorous global safety standards of both ATEX (Europe) and UL (North American) certifications, this shaft seal is the primary defense against leaks that could lead to hazardous conditions or motor failure when transferring volatile fuels.

Key Features & Benefits

• Dual Certification Safety: Specifically designed for use in ATEX and UL-listed explosion-proof pumps. This ensures the seal maintains the flame-path integrity required for Class I, Division 1 hazardous locations.
• Fuel-Proof Viton/Specialized Elastomers: Manufactured from high-grade chemical-resistant materials that won’t swell or degrade when in constant contact with Gasoline, Diesel, Kerosene, and Avgas.
• Precision Mechanical Fit: Engineered to provide a frictionless yet airtight barrier around the rotating motor shaft. This prevents “weeping” at the pump head and ensures the motor stays dry and protected from internal fuel ingress.
• Thermal Stability: Built to withstand the heat generated by continuous-duty cycles and high-RPM operation (up to 3450 RPM). The seal retains its structural integrity even under the thermal expansion common in high-flow fuel transfer.
• Self-Lubricating Design: Features a precision-lapped mating surface that utilizes the fluid being pumped for cooling and lubrication, significantly extending the service life of the seal.
• Genuine Piusi Spare Part: As an authentic Piusi R-Series component, the R24012000 guarantees a perfect fit for the Panther EX50 and related explosion-proof models, ensuring no modification to the pump housing is required.

Technical Specifications

If you notice fuel dripping from the small weep-hole located between the pump head and the motor housing, your shaft seal has likely failed. Continuing to operate a pump with a compromised seal is extremely dangerous, as it allows flammable vapors to reach the electrical motor components. Replacing a worn seal with the Piusi R24012000 restores the explosion-proof safety barrier and prevents expensive damage to the motor bearings and windings.
