Bard 910-1931 Water Flow Switch Assembly for Geothermal Water-Source Heat Pumps

The Bard 910-1931 is an OEM replacement Water Flow Switch Assembly designed for use in Bard geothermal and water-source heat pump systems. This switch monitors water flow through the refrigerant-to-water heat exchanger and acts as a critical safety device, shutting down the system in the event of inadequate or interrupted water flow to protect the compressor and refrigeration circuit from damage.

Bard water-source heat pumps rely on a continuous supply of water or antifreeze solution for heat transfer. Without proper flow monitoring, a loss of water circulation can result in coil freezing, compressor failure, or refrigerant damage. The 910-1931 flow switch provides the automated protection needed to prevent these costly failures.

Key Features:

• OEM Bard replacement part — direct fit for compatible water-source and geothermal heat pump models
• Monitors water flow through the water-to-refrigerant heat exchanger
• Triggers system shutdown upon detection of low or no water flow
• Protects compressor and refrigeration system from damage caused by flow loss
• Compatible with multiple Bard GV-series and water-source heat pump models

Always verify compatibility with your specific Bard unit model number before ordering. Use Bard OEM part number 910-1931 to ensure proper fit and reliable safety performance.
