DELUXE FLOW CENTER
Reliable operation, stylish appearance
The Deluxe Flow Center is a non-pressurized pumping station that’s housed in
an attractive, durable cabinet, and is a recommended accessory for the
installation of closed loop geothermal systems.
The Deluxe Flow Center includes patented features not available in any other
system including its built-in pump protection. This design eliminates the need
for a flush cart when filling and flushing a closed loop system with indoor
manifolds. Because it is non-pressurized, the flow center allows you to add
fluids like antifreeze or water, while automatically eliminating air from the
closed loop system.
Simple to install The Deluxe Flow Center is completely assembled at the
factory to simplify installation, which is completed by connecting a return
line from the loop system to the Deluxe Flow Center and then connecting a
supply line from the Deluxe Flow Center to the heat pump unit.
Easy to operate and maintain The QT Flow Center system includes self-sealing
features that keep air out and water in. For you, that means trouble-free
operation, easier installation and fewer call backs. For the homeowner, it
means added reliability.
Adding antifreeze is easy. Just remove the self-sealing top and pour the
liquid into the air elimination chamber. The top is completely sealed to keep
dir t and air out–an exclusive feature of the Deluxe Flow Center.
The only moving parts of the system are the pumps, helping make service
minimal. Each part can be removed for servicing without risk of fluid loss or
air entry into the system.
Smart addition to water source technology A geothermal system is a significant
investment for the homeowner and one he will want to protect. Recommending the
Deluxe Flow Center will not only add to the dependability of the closed loop
system, it will add to the customer’s satisfaction in the long run.

STANDARD FLOW CENTER
Adds dependability to a closed loop system
The Standard Flow Center is a non-pressurized pumping station that’s a
recommended accessory for the installation of closed loop geothermal systems.
The Standard Flow Center encorporates patented features not available in any
other system, including built-in pump protection. This design eliminates the
need for a flush cart when filling and flushing a closed loop system with
indoor manifolds. Because it is non-pressurized, the flow center allows you to
add fluids like antifreeze or water, while automatically eliminating air from
the closed loop system.
Simple installation The Standard Flow Center is completely assembled at the
factory to simplify installation.
The unit is installed by connecting a return line from the loop system to the
Standard Flow Center. Then connect a supply line from the Standard Flow
Center to the heat pump unit. That’s all there is to adding reliable pump
protection to any closed loop system.
Easy to operate and maintain The Standard Flow Center system is designed for
dependability. The system includes self-sealing features that keep air out and
water in. For you, that means trouble-free operation, easier installation and
fewer call backs. For the homeowner, it means added reliability.
Adding antifreeze is easy. Just remove the self-sealing top and pour the
liquid into the air elimination chamber. The top is completely sealed to keep
dirt and air out–an exclusive feature of the Standard Flow Center.
Because the only moving parts of the system are the pumps, service is minimal.
Each part is made to be removed for servicing without risk of fluid loss or
air entry into the system.
Protecting an investment A geothermal system is a significant investment for
the homeowner and one he will want to protect. Recommending the Standard Flow
Center will not only add to the dependability of the closed loop system, it
will add to the customer’s satisfaction in the long run.

Detailed part description
1. SELF-SEALING TOP–All fluids are poured in the top of the chamber for
filling, flushing and adding anti-freeze.
2. DIP TUBE–Improves system performance by preventing air entry into the
closed loop system. (internal, not shown)
3. TANK–Includes a self-sealing, removable screw-on top for ease in
installation.
4. BUILT-IN CHECK VALVE–Holds water in the pump volutes after initial
filling. This protects the pump by keeping water on the bearing even if the
chamber runs dry.
5. BALL VALVE–Allows each pump to be removed for service without the risk of
fluid loss to the system
6. PUMP(S)–Circulate fluid throughout the earth loop system (7602-404 has one
pump while the 7602-405 has two pumps).
7. AIR ELIMINATION CHAMBER–Removes air from the system as it is circulated
through the canister.
DOUBLE O-RING LOOP PUMP
O-Ring design eliminates leaks
Our Double O-Ring Loop Pump, built with a high impact polystyrene cabinet,
contains 3-way valves and pumps with connections for flushing, filling and
pumping residential geothermal closed loop systems. The double O-ring design
allows the connections to be hand tightened for ease of installation.
This enhanced, proven design is foam insulated to prevent condensation and
will not rust. Full flow service valves minimize pressure drop. The Double
O-Ring Loop Pump also utilizes the industry standard Grundfos circulator
pumps.
Installation The module comes fully assembled and leak tested; external
connections are double O-ring. The light weight module can be easily mounted
to the wall using the slotted mounting holes in the built-in mounting
brackets.
Operation The heat pump and earth loop are filled and flushed through the side
connections; the composite valves rotate to four different positions to direct
the flow of liquid solution, also allowing isolation of the heat pump or loop
as needed for maintenance.

STANDARD PRESSURIZED LOOP PUMP
Circulates fluid through a closed loop
Our Standard Pressurized Loop Pump modules, used for closed loop geothermal installations, are designed to circulate the liquid solution through the heat exchanger of the geothermal heat pump, out through the loop and back, so heat transfer can occur.
The pump module is compact at just 14 1/8″ tall and engineered for quiet,
reliable operation. The heave duty cabinet is insulated with thick foam to
eliminate condensation and includes full flow 1″ brass valves.
Installation The module comes fully assembled and leak tested; external connections are 1″ FPT. The module can be easily mounted to the wall using the slotted mounting holes in the built-in mounting brackets. Connection of the module to the heat pump is quick and easy with the hose kit listed below.
Operation The heat pump and earth loop are filled and flushed through the side
connections; the two brass valves rotate to four different positions to direct
the flow of liquid solution, also allowing isolation of the heat pump or loop
as
needed for maintenance.
