PumpGuard Pump Protection System

For pumps handling flammable liquids, the specifically designed PumpGuard System combines preventative monitoring with active fire suppression to rapidly extinguish a potential fire before it has the chance to spread—all in a low-cost, easy-to-install package.

Primary advantages over conventional methods:

  • Preventative instrumentation to detect early signs of failing equipment- allowing you to stop a fire before it even starts

  • Suppressant foam is much more localized, leading to more effective suppression and easier cleanup than conventional systems

  • Individual foam canisters do not degrade over time like the pressurized bladders common in full-room foam systems

Key features/benefits:


  • Dual guard housing system with cooling air increases pump seal longevity while preventing fires from spreading

  • Dedicated system for each pump

  • Combines 3 layers of protection:

• Forced air cooling of seal to prevent failure and improve life

• Preventative monitoring of key failure indicators to predict failure before it happens, and

• Active auxiliary fire suppression using a foam agent to extinguish a seal fire should it occur

  • Fail-safe operation using mechanical fire detection – no reliance on power  

  • Several configuration options- customizable for your operation’s specific requirements and layout


Wech Tech’s PumpGuard+ includes all of the features of the base PumpGuard package PLUS dual-zone fire suppression to both the mechanical seal AND the pump volute housing, providing total protection of the entire pump area.
