Graco 15B502 Diaphragm FDA Viton 2150

Graco 15B502 FDA Viton 2150 Diaphragm – Product Details & Compatibility

Compatible Machines

The Graco 15B502 FDA Viton 2150 Diaphragm is engineered for use in the diaphragm chamber of the Graco Husky 2150 series air‑operated double diaphragm (AODD) pumps where a high‑performance Viton (fluoroelastomer) diaphragm and FDA‑rated elastomer are required.

• Graco Husky 2150 AODD pumps and FDA/sanitary variants requiring Viton diaphragms
• Pump systems in food & beverage, chemical transfer, coatings or sanitary fluid‑handling applications specifying the 2150 series
• Replacement or service kits aimed at restoring diaphragm performance, sealing integrity and durability in demanding environments

Product Overview

The Graco 15B502 FDA Viton 2150 Diaphragm is a precision‑manufactured OEM diaphragm made from FDA‑compliant Viton (fluoroelastomer), designed to meet the demands of the 2150 pump series. It offers outstanding chemical resistance, elastic durability under frequent cycling, and reliable fluid/air separation. By using this exact diaphragm you restore the pump’s designed stroke, maintain sealing integrity and ensure high performance even in sanitary or high‑throughput applications.

Key Features

• Material: Viton (fluoroelastomer) – FDA‑rated for high chemical resistance and durability
• Manufactured to OEM tolerances for the 2150 series to ensure correct fit, stroke and performance
• Optimised for frequent cycling typical of industrial and sanitary pump systems
• Maintains reliable chamber displacement, fluid isolation and prevents air intrusion or cross‑contamination
• Ideal for demanding fluid‑handling systems requiring sanitary or food‑grade elastomer compatibility while maintaining heavy‑duty service life

Usage Notes

• Ensure the pump is fully depressurized and isolated from fluid before removing or installing the diaphragm to prevent injury or damage.
• Inspect diaphragm chamber, seat and mating surfaces for wear, corrosion or damage prior to installing the new diaphragm.
• Clean all mating surfaces, align the diaphragm correctly and install according to OEM instructions to ensure proper stroke, sealing and reliability.
• After installation, run a test cycle under normal operating conditions to verify proper displacement, no leaks and intact sealing.
• Replace the diaphragm if you notice cracks, extrusion, permanent deformation, air intrusion on the liquid side, reduced throughput, or if the maintenance interval is reached — delayed replacement can result in more extensive pump service.
