MULTI ZONE GT FLOW CENTER
The best pumping solution for a geothermal heat pump system. Unsurpassed in delivering the following benefits:
- Ease of Installation
- Very Low Operating Costs
- Ease of Maintenance
- Individual Tenant Metering
- Control Simplicity
Sealable Lid - Provides for a closed sealed system while allowing for ease of access to sample fluid and measure flow rate.
Inlet Connection - Stainless Steel. MPT connection provided as standard, with various transitions available upon request. Size based on canister size (see chart below).
Check Valves - Check valves are provided in each pump circuit assuring proper flow and reliable pump operation.
Canister - Provides a standing column of water on the suction side of the pump(s) to insure a flooded volute and reliable pump operation. Size required is based on max load design flow rate(see chart below).
Optional Ball Valve - Butterfly valve is available as an option to isolate canister from pump manifold(not shown).
Pump Connection - 1 1/4” FPT brass with isolation ball valve.
Pump Control - Pumps can be directly controlled with a branch circuit from the heat pump or controlled with a relay box.
Pump Circuits - Individual pump circuits consisting of one, two or three 1/6 HP circulating pumps. Capable of delivering upto 25 gpm @48 ft of H20. Grundfos 116F is standard with others available upon request. For flow rates greater then 25gpm larger end suction pumps are available. Voltage 230-1ph.
Pump Isolation - 1 1/4” brass isolation ball valves provided above and below each pump (or set of pumps) allowing for service of one circulator while the rest of the system is functional.
Insulation - 3/8” armaflex insulation factory installed to prevent condensation.
Pump Manifold - Factory assembled manifold, including check valves, one isolation valve per circuit and drain valve at end of manifold 4 circuits & larger (not shown).
Manifold Connection - Flange provided to field assemble the pump manifold to the canister and allowing for installation of optional butterfly valve.
