The Chesterton Flow Guardian™ meters are engineered to provide continuous regulated seal flush water, enhancing pump efficiency and reducing costly seal failures. These meters support plant water conservation efforts by reducing seal water flush rates without compromising performance.

Flow Guardian™ Seal Meters contribute to water conservation programs by reducing seal flush water from gallons per minute to gallons per hour, aligning with federal mandates and improving operational efficiency.

Designed for dual seals, these meters ensure optimal cooling and lubrication by accurately measuring water flow. They feature a built-in regulating valve for adjusting flush pressure, ensuring reliable seal performance.

The meters feature clear flow tubes that can be cleaned without interrupting flow. The built-in plunger removes contaminants, maintaining visibility and flow. The design allows contaminants to pass without blockage, enhancing reliability.
