Firstco 940-3-CV Circulating Pump Flow Control Module 3 GPM

The Firstco 940-3-CV is a circulating pump flow control module designed for hydronic heating systems, required when coils are piped to water heaters or other hot water sources without a circulating pump. This complete assembly is ideal for Aqua Therm systems and similar hydronic applications.

Key Features:

• 3 GPM flow rate capacity for efficient heating performance
• Includes circulating pump, pump relay, check valve to eliminate thermosyphoning, 6-foot plug-in line cord, and large air purge valve
• Check valve prevents reverse flow and thermosyphoning when the system is off
• Large air purge valve simplifies system installation and maintenance
• Ready to install with integrated 6-foot power cord
• Engineered for reliable operation in residential and light commercial HVAC applications

This flow control module provides complete pump functionality in one compact assembly, eliminating the need to source individual components. The integrated relay ensures proper pump cycling, while the check valve protects system integrity during off-cycles. Compatible with standard 7/8-inch O.D. copper piping for installations where the coil-to-heater distance is 20 feet or less.
