3 About Geo-Flo is the industry-leading manufacturer of flow centers for residential and commercial geothermal applications, as well as a complete supplier of pipe, fittings, and accessories. Founded in 1988 by CEO Tom Miller, Geo-Flo has focused on solutions that create more reliable, easier to install, and more efficient products. In the late 198s the geothermal heat pump industry had a multitude of problems with available technology for reliable flushing/service valves. In 199 Geo-Flo introduced its new three-way valve body with valve ports supporting full one-inch flow. The new valve body was designed for the low fluid temperatures associated with the application, and increased the reliability of flow centers in the marketplace. 199: Flow Center with 3-way full flow brass valves 21: Composite 3-way valve In 21 Geo-Flo designed a new composite front flush valve as a lighter weight alternative to brass and with additional capabilities. Geo-Flo was the first to utilize a composite material and exclusive Flo-Link double O-ring adaptors in a flow center. This revolutionary design is still in use today, and is also available as a brass valve. In 25 Geo-Flo introduced a rustproof, high-impact polystyrene cabinet using Flo-Link front flush valves. This specially tooled molded cabinet with rounded corners and a sleek design raised the bar once again for flow center design. A similar version (redesigned in 27) is used today on the majority of residential and light commercial geothermal applications because of the decreased weight, superior reliability, and aesthetics of the cabinet design. Improving upon the three-way valve design, Geo-Flo introduced a new die cast valve (winner of the North American Die Casting Association competition) in 26, providing more consistency in quality, as well as a lighter weight flow center. The ability to remove the entire valve spool to replace the seals makes this design the most flexible 25: Flo-Link double O-Ring flow center with high-impact polystyrene cabinet 2

4 About Geo-Flo flush valve on the market (all Geo-Flo valves have this capability). No other valve type can compare to the reliability and durability of the Geo-Flo spool valve design. There are more Geo-Flo valves installed in the geothermal heat pump industry than all other flush valves combined. Continuing with Geo-Flo s focus on solutions, the Pressure Battery, the industry s first polyethylene expansion tank was also introduced in 28. This new product solved an age-old problem of pressure fluctuations in the ground loop system, potentially causing call-backs to re-pressurize the loop. VersaFlo commercial flow center The VersaFlo flow center, introduced in 29 is the most Pressure Battery versatile commercial flow center available. One or two PE expansion tank pumps with 2 full flow 3-way flushing and service valves are installed in a foam-insulated powder-coated steel cabinet, providing up to 1 U.S. GPM flow rates in a compact arrangement. Grundfos UPS32-16, UPS4-16, and UPS speed pumps allow for a complete range of applications. The Flo-Link XL 2 double O-ring valve and XL fitting selection provides union connections and flexiblity with numerous transition fittings. SuperBrute XL An additional commercial product line, the SuperBrute XL series was added in 21 to provide customers with a light commercial or large residential (multi-unit) product offering. Building upon the success of the 3-way valves in residential flow centers, the SuperBrute XL uses 2 full flow 3-way flushing and service valves, integrated into a foam-insulated powder-coated steel cabinet. Three-speed Grundfos UPS6-15 pumps allow application of 12 to 15 ton systems with one flow center. The original GPM series (steel cabinet) was updated in 21 to the new foam insulated ABS cabinet, and the 3-pump and 4-pump flow centers were upgraded to a steel cabinet with foam insulation. Also in 21 Geo-Flo added a non-pressurized (hybrid) option to its flow center product line, the Geo-Prime tank. Geo-Prime may be installed in a new installation, or can be retrofitted on a system with loop pressurization concerns. Geo-Flo recommends either a Geo-Prime tank or Pressure Battery expansion tank on every residential pressurized installation to alleviate loop pressure concerns. Labor-saving foam insulated boots were added to many of the hose kits in 21 to create a nicer-looking installation and avoid some issues with condensation from uninsulated or poorly insulated elbows. The Geo Booster, introduced in 211, is an active loop pressurization system that eliminates issues with low loop pressure in closed-loop geothermal ground loop or hydronic applications. It is a great solution for older geothermal installations that might have a small, hard to find leak; or in multi-unit installations with large ground loops and multiple circulation pumps. Adding again to Geo-Flo s commercial product offering, the Wilo Stratus commercial flow centers became available, providing variable speed pumping and external control capabilities. Also in 211, Geo-Flo added a flush cart to its service tools catalog. The flush cart, coupled with a 1-1/2 HP Munro pump, operates on 115V. The flush cart can typically flush 1 to 12 circuits (3/4 PE), connected in parallel. Geo-Prime tank shown connected to flow center 3

5 About Geo-Flo In 212 Geo-Flo became the first to use the Grundfos GEO Magna variable speed pump with a dedicated controller. The controller has a program specifically designed for Geo- Flo, allowing selection of flow rate (including two-stage heat pumps) or delta T mode. The GEO Magna can be controlled directly from the user interface without any external input, and works with virtually any geothermal heat pump. The savings in operating costs can be substantial over traditional circulators. Also in 212 Geo-Flo introduced a new product for pond loops, spaced 3 ft. 3/4 PE coils. Pre-installed spacers allow flow through the coils, and save a considerable amount of labor at the time of installation. In 213, Geo-Flo introduced a number of new products. Geo- Flo moved into new markets with products like the NP series Flo-Link double O-ring flow center with Grundfos Magna GEO variable speed pump flow center. The NP series flow center is a non-pressurized column-type flow center with Geo-Flo s exclusive 3-way valves and Flo-Link double O-ring fittings. This product provides another method of installation for geothermal heat pump applications. Pressurized (flow center and Pressure Battery), hybrid (flow center and Geo-Prime), or the NP series nonpressurized flow center are solutions that reduce installation time, decrease call-backs, and increase long-term reliability. Another product introduced in 213 was actually a service. A complete suite of web calculators is available at to assist in the design/selection of ground loops and pumps. NP NP Series Non-pressurized Flow Center Other 213 products included new insulated pumps with isolation valves, controls for multi-unit applications, and a number of new fittings and accessories.

6 Residential Flow Centers Flo-Link & GPM series Pressurized Flow Centers Geo-Flo s most popular residential flow centers are available in a wide variety of combinations. Flo-Link double O-ring style flow centers are unsurpassed in ease of installation. Flo-Link double O-ring fittings provide leakfree union connections at the flow center, installed without tools (no need for pipe wrenches). Virtually any type of transition (fusion, thread, barb, PVC glue, etc.) is available for Flo-Link fittings. Geo-Flo s full port 3-way flushing and isolation valves are designed for the wide range of temperatures experienced in ground loop applications. Flo-Link flow centers are available through heat pump manufacturers and their distributors. Flo-Link series foamed flow center with high impact polystyrene cabinet (shown with variable speed Grundfos Magna GEO pump): Flo-Link flow centers are available in one pump and two pump configuration with variable speed (UPS32-14) and constant speed (UP26-99, UPS26-99, or UP26-116) pump(s). Flo-Link double O-ring fitting sets for union/transition to flow center: See Accessories / Pipe / Fittings section for complete assortment of Flo-Link fittings. Flo-Link flow centers include volutes specially designed for Geo-Flo, which allow the entire power head to be external to cabinet. This provides additional flexibility for installers and service technicians when a pump head needs to be rotated, or when a single pump flow center needs to be upgraded to a two pump flow center. GPM series foamed flow center with steel, powder-coated cabinet (shown as GPM-3, three pump--also available as GPM-4) GPM series foamed flow center with ABS plastic cabinet (shown as GPM-1, single pump--also available as GPM-2) Field upgradable to two pump flow center GPM series continues on next page 5

7 Residential Flow Centers Flo-Link & GPM series Pressurized Flow Centers The GPM series flow centers utilize reliable 3-way valves with the same features and benefits as the Flo-Link valves, but have threaded FPT connections. GPM flow centers are available in one to four pump configurations, and may be ordered with or without the foamed cabinet. The cabinet is designed to allow pump heads to be rotated, or for upgrading/downgrading (i.e. adding/removing a pump). In addition, GPM flow centers are available with isolation valves for applications where the flushing valves are located underground or remotely (see Accessories section). GPM series bracket style flow center: (Left is GPM-3; right is GPM-1 (also available as GPM- 2, and GPM-4). Designed for Southern applications, where ground loop temperatures do not cause condensation. Pressure Battery: The industry s first polyethylene fusion expansion tank maintains system pressure via a custommolded internal rubber bladder. The completely sealed tank never needs maintenance, and may be installed in the mechanical room, or even buried outside with the ground loop. Designed for up to 6 tons (approx. 3/4 gallon). Geo-Booster: An active loop pressurization system that eliminates issues with low loop pressures in closed loop geothermal ground loop or hydronic systems. The Geo Booster will maintain a minimum loop pressure of 35 psig on the system. The Geo Booster includes a pump with a built in pressure switch factory set at 35 psig, and a check valve to prevent back flow into the one gallon tank. The sealing cap ensures a closed system, prevents loop fluid evaporation, and provides vacuum relief allowing the fluid to be pumped from the reservoir. 6

8 Residential Flow Centers Geo-Prime Series Hybrid Flow Centers The Geo-Prime series is a hybrid system with a tank that may be added to a standard pressurized flow center or pump to create a non-pressurized system. In addition to its applicability in a non-pressurized system, the tank can be used as an add-on to traditional pressurized systems. In either case, the Geo-Prime ensures that the pumps receive only air-free loop fluid and provides enough additional make-up fluid to prevent call-backs associated with loop expansion during seasonal temperature changes. The Geo-Prime Tank consists of a fluid reservoir, two bypass valves and an air-eliminating dip tube inside of a foam-insulated cabinet. The tank includes a sealing cap with integrated pressure and vacuum relief to prevent the reservoir from being over-pressurized or collapsing. The tank is mounted above the suction flange of the pump to ensure a flooded volute and to provide the necessary suction head pressure for the pump. Benefits Include: HDPE construction with fused joints Single pass internal air separation Integrated pressure/vacuum relief in sealing cap Integrated bypass valves to allow ground loop system to be flushed with industry standard flush cart Utilizes Flo-Link double O-ring connections for easy installation Integrated sight glass for fluid level monitoring without removing cap Approx. 2.5 gallon fluid capacity Foam insulated high impact polystyrene cabinet Modular system: may be used with pressurized flow center or insulated pump. Geo-Flo insulated pumps with Flo-Link double O-ring fittings may easily be connected to the Geo-Prime tank with the valve coupling adapter fitting supplied with the Geo-Prime tank. Typical Application: Geo-Prime is installed above flow center. An insulated pump may also be used instead of a flow center when 3-way flushing valves are not needed (see picture to the left). 7

9 Residential Flow Centers NEW! Panel Mount Variable Speed Flow Centers In Geo-Flo s ongoing efforts to create products that are easier to install and time-saving, there are several new packages for variable speed pumping options that completely eliminate the need for wiring the controller.

12 Residential Flow Centers NP Series Non-Pressurized Flow Center The new NP series non-pressurized flow center raises the bar for non-pressurized applications. Building upon Geo-Flo s 3-way flushing valves with Flo-Link connections, the NP series reduces installation time, and increases reliability. In fact, by incorporating flushing valves into the flow center, the ground loop may be flushed without adding external flush ports, saving installation time and additional cost. Plus, piping becomes much simpler. Flo-Link double O-ring include transition fittings for most any application (PE fusion, PVC, threaded, etc.). Top or side connections to the heat pump and ground loop add even more flexibility. Pump selection for the new NP series is the ultimate in flexibility. Geo-Flo is the first to use the redesigned UPS26-99 Grundfos 3-speed pump. Or, the new variable speed Magna GEO may be selected for even more operating costs savings. Current options are as follows: NP 1 -- Grundfos UPS26-99 or UP NP 2 -- Two UPS26-99 (3-speed) or UP pumps NP V -- Variable speed Magna GEO -- One Magna GEO and one UPS26-99 NP V2 NP The NP series has many installation/service-friendly features. One of the best is the GEO-METER flow tool, shipped with both elbow and straight adapter fittings. For even more flexibility, an adapter is available to use this tool with the competition s flow center, providing a one tool fits all solution.

14 Residential Flow Centers NEW! NP Series Dual Circuit Non-Pressurized Flow Center The new NP series Dual Circuit non-pressurized flow center is the next evolution in Geo-Flo s NP series. By incorporating flushing valves into the flow center, the ground loop may be flushed without adding external flush ports, saving installation time and additional cost. Plus, piping becomes much simpler. Flo-Link double O-ring transition fittings are available for most any application (PE fusion, PVC, threaded, etc.). Top or side connections to the ground loop add even more flexibility. The NP series Dual Circuit flow center is specifically designed for applications with two geothermal heat pumps by eliminating the need for T s, additional piping, check valves, and pump sharing relays. Simply connect the ground loop to the 3-way valves at the top of the flow center (side or top connections) and the heat pumps to the side connections. The pump(s) on each side is powered only when that heat pump is running. There is no easier method available on the market today for two-unit installations.
