PIUSI ORINGS KIT for EX 80/100/140 Part R23138000

Description

Piusi O-Ring Replacement Kit – EX80 / EX100 / EX140 Series

Part is original to Piusi.

Product Code: R23138000

The Piusi R23138000 is a comprehensive OEM sealing kit specifically engineered for the high-flow EX80, EX100, and EX140 explosion-proof pump series. In high-performance fuel transfer, the integrity of the internal seals is the only thing standing between a high-efficiency operation and a hazardous leak.

This kit includes all the critical elastomeric O-rings required to perform a full “wet-end” maintenance or repair. Because these pumps are designed to move flammable liquids like gasoline and high-volume diesel, using the genuine UL/ATEX-certified sealing kit is mandatory to maintain the explosion-proof safety rating of your equipment.

Key Features & Benefits

• Complete System Sealing: This kit is not just a single seal; it contains the full array of O-rings needed for the pump head, the internal bypass valve assembly, and the suction/delivery manifolds.
• Explosion-Proof Safety Standards: Specifically formulated to meet the rigorous requirements of UL (Underwriters Laboratories) and ATEX certifications. These seals ensure that flammable vapors and liquids remain contained within the pump’s “flame-path.”
• High-Grade Fuel Resistance: Manufactured from premium Viton or specialized NBR (Nitrile) compounds that are chemically resistant to Gasoline, Diesel, Kerosene, and Avgas. These materials are designed to resist the swelling and degradation that lead to seal failure in inferior aftermarket parts.
• Restore Vacuum Integrity: New O-rings are essential for maintaining the pump’s self-priming capability. By ensuring a 100% airtight seal on the suction side, this kit helps your EX-series pump reach its maximum rated GPM (up to 35 GPM for the EX140).
• Thermal Stability: Engineered to maintain a flexible, leak-proof barrier across a wide temperature range, from extreme winter cold to the high heat generated during continuous-duty fueling cycles.
• Genuine Piusi Spare Part: As an authentic Piusi R-Series kit, the R23138000 guarantees a precision fit for every internal groove and flange, eliminating the “guesswork” of generic hardware.

Technical Specifications

Over time, even the highest-quality seals can harden or flatten due to “compression set” and constant exposure to volatile fuels. If you notice “weeping” at the pump head or if your EX100 is struggling to prime, the seals are likely the culprit. Replacing the entire set with the Piusi R23138000 during your annual maintenance is a cost-effective insurance policy against expensive fuel loss and dangerous environmental contamination.
