PIUSI ANTISIPHONE KIT FOR EX50 & EX75 Part F20305000

Description

Piusi Antisiphon Kit – EX50 & EX75 Series

Part is original to Piusi.

Product Code: F20305000

The Piusi F20305000 is a critical safety and environmental protection accessory designed specifically for the EX50 and EX75 explosion-proof pump series. In fuel storage configurations where the tank’s liquid level is higher than the discharge nozzle (such as elevated skid tanks or top-loading tanks), gravity can create a continuous flow—a “siphon”—if a hose is damaged or a nozzle is left open.

This kit provides an automatic atmospheric break, instantly stopping the flow of fuel the moment the pump is deactivated. Engineered to meet the rigorous safety standards required for gasoline and diesel transfer, the F20305000 is an essential component for regulatory compliance and spill prevention.

Key Features & Benefits

• Explosion-Proof System Safety: Built to the same high standards as the UL/ATEX-listed EX-series pumps. It is designed for use in hazardous locations where flammable vapors (Gasoline, Kerosene, Avgas) are present.
• Automatic Siphon Prevention: Utilizes a precision-calibrated internal valve that opens under pump pressure and closes the moment the motor stops. This prevents gravity-fed leaks that could lead to catastrophic environmental contamination and fuel loss.
• Integrated Check Valve Function: Maintains the “prime” in your suction line, ensuring that fuel is immediately available at the nozzle the next time the pump is turned on. This reduces wear and tear on the pump’s internal vanes and prevents dry-start friction.
• Industrial Grade Durability: Constructed from corrosion-resistant, spark-proof materials capable of withstanding the mechanical stress of high-vibration environments and harsh outdoor weather.
• Optimized for EX50 & EX75: Specifically balanced for the flow rates of the EX50 (15 GPM) and EX75 (20 GPM), ensuring that the safety mechanism does not cause unnecessary flow restriction or backpressure.
• Genuine Piusi Engineering: As an authentic Piusi Accessory, the F20305000 ensures a perfect thread match and hydraulic balance with your existing EX-series pump manifold.

Technical Specifications

Environmental regulations often mandate antisiphon protection for any fuel system where the “static head” (fuel level) sits above the lowest point of the dispensing hose. A small tear in a hose on an elevated tank without this kit could result in the entire contents of the tank draining onto the ground. The Piusi F20305000 offers “set-it-and-forget-it” peace of mind, ensuring that fuel only moves when you intend it to.
