Geo-Flo NPD3 Dual Circuit 3 Pump Flow Center

The NP series Dual Circuit flow center (NPD) is specifically designed for applications with two geothermal heat pumps.  The NPD saves installation time and cost by eliminating the need for external T’s, additional piping, check valves, and pump sharing relays.

• Specifically designed for two unit applications
• Non-pressurized operation
• Built-in 3-way valves allow flushing/purging air directly at the flow center
• Heavy gauge powder-coated steel cabinet
• Completely foam insulated cabinet helps prevent condensation at low temperatures
• Pressure/vacuum relief cap never lets the tank go into vacuum or above 13 psig.
• Internal check valves prevent short cycling
• Selection of one or two pumps for each side
• Selection of Grundfos UPS26-99/3-speed or UP26-116 single speed pumps
• Flo-LinkTM double O-ring connections provide union connections at the flow center
• Compatible with standard hose kits
• Saves energy by only energizing the pump(s) needed when only one heat pump is running
• Allows pump replacement without reflushing the ground loop
• Manufactured in the USA

• Geo-Flo Part number 1305
