CAT Pumps 9953 High-Flow Stainless Steel Pop-Off Valve

The CAT Pumps 9953 is a high-capacity Stainless Steel Pop-Off Valve engineered to serve as a critical secondary pressure relief device in heavy-duty industrial pumping systems. Designed to safely handle massive flow rates up to 50 GPM, this valve protects expensive pumps and downstream system components from catastrophic damage in the event of a primary regulator or unloader failure. By allowing fluid to instantly flow freely during an over-pressurization event, it prevents component ruptures and costly downtime. This specific model is strictly calibrated for high-pressure networks operating between 1500 and 3000 PSI.

Constructed entirely from corrosion-resistant 316 Stainless Steel with premium NBR internal O-rings, the 9953 is built to withstand harsh, aggressive fluids. This makes it a required safety component for demanding applications such as Salt Water Reverse Osmosis (SWRO) desalination, leachate treatment, chemical processing, and industrial wastewater reclamation. Proudly manufactured in the USA, it features a lightweight, compact design with a 1" NPT(M) inlet that allows for quick and convenient direct mounting into the discharge line.
