Alpha Series Pumps
The Alpha Series pumps by Grundfos are equipped with the latest technology to provide you the most efficient use of the pump. These pumps have permanent magnet motors designed for circulating water through domestic hot water systems, heating systems, or cooling and air conditioning systems. The Alpha pumps can be used in systems with either constant or varying water flow rates.
example of a Grundfos ALPHA pump The Alpha pumps incorporate a frequency converter, an integrated differential pressure control, and an electronic processor to automatically adjust pump speed based on the system demand and flow rates. The AUTOADAPT software recognizes changes in the system like opening and closing valves or faucets that can cause a change in the head-flow requirements of the system. AUTOADAPT monitors the motor current versus the pump hydraulic or pressure conditions and automatically adjusts the motor speed to minimize the pumps energy consumption and at the same time maximize your system needs for your comfort level.

Cast iron pumps are ideal for closed systems such as hydronic heating, radiant heating, or cooling and air conditioning systems and should not be used for open systems like domestic hot water systems. A closed system is one in which you very rarely add fresh water into the system, all air and bubbles are removed from the system, and the same water is circulated through the system. An open system is one in which fresh water is frequently added to the system like when the hot side of a faucet is opened forcing cold water to enter into the water heater. Stainless steel pumps should be used for domestic hot water circulation systems since they are lead free and will not fail like a cast iron pump due to rust or corrosion caused by constant fresh water introduced in an open system.
Each Alpha pump has three settings to choose from; Constant Pressure, Fixed Speed. or AUTOADAPT. Setting the pump is easy with a simple one-touch of a button on the face of the pump. The AUTOADAPT control mode is the default setting as it is suitable for most applications, providing automatic adjustment of the pump. The "Constant Pressure" mode allows you to manually choose one of three speeds for use with heating systems with variable flow rates and constant pressure. The "Fixed Speed" mode allows you to manually choose one of three speeds for use with heating systems with constant loads. An easy to read LED display on the face of the pump shows actual power consumption of the pump in Watts.

Heating / Cooling Circulators - for Closed Systems
These Grundfos circulating pumps operate whisper quiet for sound sensitive applications. 3-speed pumps offer more flow rate flexibility than single speed pumps and are manually adjusted to the preferred speed by the user as needed. Speed adjustment of 3-speed pumps should not be done while the pump is in operation.
example of a Grundfos 3 speed circulating pump
UPS15-58FC shown
The UP and UPS series pumps are a canned rotor type. The motor and the pump are made as an integral unit without the need of a shaft seal and only two gaskets are used for sealing. The pump has a ceramic shaft and radial bearings with a carbon thrust bearing. The bearings are lubricated by the pumped liquid. Pumps housings are made in cast iron, bronze or stainless steel for use in appropriate liquids and water conditions. The impellers are made of a durable, corrosion resistant, PES (30% glass filled).

The maximum allowable liquid temperature of these pumps are determined by the ambient or surrounding air temperature around the pump. If any UP pump is equipped with a timer, the maximum liquid temperature is 150° F (66° C) even if the pump specifications show a higher temperature. The UP and UPS 25, 26, 43,and 50, pump types can be used with chilled water due to their motor construction, which is suitable for 32° F (0° C) as long as the pump housings are compatible with the pumped liquids.
Variable speed pumps can be set for variable speed operation or can be set manually to operate at one speed. The motor variable speed selection is set by the user adjusting 4 switches (called "dip switches") located on the pump, in a predetermined sequence by the manufacturer. The user can select the pump control signal to run by voltage or current. Voltage: 0-10V(DC) or 2-10V(DC). Current: 0-20mA or 4-20 mA. A multifunction dial on the front of the terminal box allows the user to fine tune the variable speed input or to manually adjust the speed of the pump.

The Grundfos MixiMiser is the only pump and controller system of its kind. The mixing-reset control automatically calculates and controls water temperatures according to outdoor temperatures in primary and secondary heating systems. The MixiMizer can be installed into a thermostatic or zoning control system for maximum design flexibility. A fully serviceable check valve is installed into the pump housing to eliminate unwanted, uncontrolled, flow when the pump is not on and will not inhibit water flow when the pump is on. LED indicators located on the terminal box indicate pump performance and help diagnose possible faults without the use of tools.


Cast Iron Pumps
Cast iron pumps are excellent for use in radiant heating systems, hydronic baseboard or floor heating systems, fan coil heating systems, heat recovery/heat pump systems, geothermal heating systems, closed solar heating systems, air conditioning systems and other chilled water applications.

Grundfos cast iron pumps are intended for use in closed systems with potable or non-potable water, softened water or with a 50/50 mixture of water and propylene glycol. If water conditions exist that are not compatible with cast iron, then Grundfos recommends the use of a bronze or stainless steel pump. These can be installed in both vertical and horizontal lines.

Hot Water Recirculation and Open System Circulators
Grundfos Bronze and Stainless Steel circulating pumps are used for hot water recirculation and open systems because these materials are not effected by air and oxygen released into these types of systems through the constant introduction of fresh water. made for whisper quiet operation for sound sensitive conditions.

The maximum temperature of liquids to be used with these pumps will vary by pump and the maximum liquid temperature will be directly effected by the ambient or surrounding air temperature around the pump. If a UP pump is equipped with a timer, then the maximum allowable liquid temperature is 150 °F (66 °C). The Grundfos UP and UPS pump types 25, 26, 43,and 50, can be used with chilled water because their motor construction is suitable for temperatures as low as 32 °F (0 °C) as long as the pump housings are compatible with the pumped liquids.

3-speed pumps are adjusted manually by the user to the preferred speed as needed offering more flow rate flexibility than single speed pumps. Speed adjustment should not be done while pumps are in operation.

Variable speed and mixing-reset control pumps are used to customize heating systems to increase user comfort. Variable speed pumps can be set for variable speed operation or can be set manually to operate at one speed. The motor output can be set to run at a variable speed by either voltage or current. The motor output is set by adjusting 4 switches (called "dip switches") located on the pump, in a predetermined sequence by the manufacturer, to control by Voltage: 0-10V(DC) or 2-10V(DC); Current: 0-20mA or 4-20 mA.


Bronze Pumps
Bronze pumps are not only excellent for use in domestic radiant baseboard heating and hydronic floor heating systems, fan coil heating systems, heat recovery/heat pump systems, geothermal heating systems, but also for open solar heating systems and circulation of liquid in cooling and air conditioning systems. Grundfos bronze pumps are manufactured for use with potable or non-potable water, softened water or with a 50/50 mixture of water and propylene glycol. These Grundfos bronze pumps can be installed in both horizontal or vertical piping installations.

to many more quality circulator pumps by Grundfos

Frequently Asked Questions

Q. "I'd like to have hot water without much of a wait. How can I do this?"
A. The two easiest solutions are:
A) A tankless water heater at the source.
B) A hot-water recirculation system. This consists of a small pump and a return line from your farthest fixture. The pump mounts near the bottom of your water heater along with a swing check valve (see diagram below).

Q. "Does a hot water recirculating system use up a lot of energy?"
A. Both options use energy. But not as much as most people think. On the recirculating system we highly recommend insulating all of your hot water pipes. Also having a timer and/or a thermostat will use even less energy. An electric tankless water heater doesn't use any energy when you're not drawing hot water.

Q. "Is the thermostat adjustable?"
A. The thermostatic control automatically turns the circulator off when the temperature exceeds approximately 105°F and back on when the temperature drops below approximately 85°F. The thermostat is not adjustable. You can click here to read more info about the thermostat.

Q. "Your timer seems expensive. Is it necessary?"
A. Most three-prong wall timers should work, but Grundfos makes a fantastic timer for their most popular model (#UP15-18SU). It can be set in 15-minute increments, mounts right onto the pump, and is the best timer we have ever seen. You can click here to read more info about the timer.

Q. "On your cast iron pumps you say that they are only for a closed system. What is a 'closed system'?"
A. A closed system is a recirculation loop for water (or other liquid) where once it is set up and running, no new liquid is introduced into the system. If new liquid is brought into the system it will bring air with it and over time this will rust out a cast iron pump.

Q. "Why don't you recommend ordering thermostats with the line cord pumps?"
A. Due to these pumps being pre-wired, they would require re-wiring in order to use the thermostats, so we recommend you purchase the pump, thermostat and timer separately when you want to use a thermostat.

Q. "Why do I need flanges/unions?"
A. The threads on the pumps are designed to attach only to the flanges or unions. There are many different sizes and types of pipe. Using flanges/unions means they don't have to make a different pump for every different size & type of pipe.

Q. "I am purchasing a replacement Grundfos pump. Next to the pump it states: 'one set required.' Must I (am I required to) order flanges/unions along with the pump or can I just order the pump?"
A. If it is an identical replacement Grundfos pump you certainly don't need to purchase flanges/unions again. The ones that you currently have "should" fit fine.

Q. "How is the quality of a Grundfos brand pump?"
A. We know of no finer made pump. Having said that we do want you to realize that every pump has a specific function. Meaning, for example, a circulating cast iron pump isn't generally for domestic drinking water. Every pump also has a specific flow rate, etc. so please don't assume that you can simply order the lowest priced Grundfos pump and that it will work for your situation. Grundfos is top quality but recognize that a $20,000 bicycle might not go as fast as a $15,000 car.

Q. "On your flanges/unions, what does 'ISO' mean?"
A. The ISO (isolation) flanges have a screwdriver shut-off built into them so the pump can be removed from the system without turning off the water supply.

Q. "Which pump would you recommend for most residential recirculation systems?"
A. Our most popular unit is the #UP 15-29SU (formerly the #UP15-18SU). It's a very quiet unit and uses less electricity than most light bulbs (65 watts!). For even more savings you can also incorporate a timer and/or thermostat.

Q. "You offer/show such a great selection and since I need the pump right away am worried that it won't ship right after I order it. How's your inventory on these?"
A. Over 95% of the pumps are always in stock and ship within 24 hours of us receiving your order (Mon-Fri).

Q. "What is the benefit of installing an optional timer or thermostat?"
A. Either one will save energy (and money). The timer only allows the pump to turn on at certain times. So if you only need hot water in the morning, you could set the timer for 6am to 8am. Then the pump would only recirculate the hot water during that time. The thermostat turns off the pump when the water in the pipes reaches a certain temperature. So once the water in the pipe is hot, the pump turns off. When the timer and thermostatic controls are installed together, in series, the circulator operates ONLY at the preset clock times specified by the user AND ONLY when the temperature conditions of the thermostat are met. That is, if either the timer control or the thermostatic control switch is open (off), the circulator will not operate.

Q. "What else would I need to install a hot water recirculation system?"
A. You'll need the pump & flanges/unions of course; a swing check valve, and pipe and pipe fittings to run the return line back to the pump. A timer and/or thermostat are optional. (click here for instructions and more info on these).

Q. "Are the Grundfos stainless steel pumps specified for potable hot water?"
A. Absolutely. They are an excellent choice for drinking water.

Q. "I want to install a hot water circulation loop so that I can get hot water quickly at my taps. My problem is that I have to pump it up about 20 feet and I only have 40 psi. Will a 1/2" return line work ok?"
A. You could even use 3/8" on the return line (after the last fixture). Best to go with 1/2" but there is no reason to use 3/4" pipe. When your system is entirely under pressure, while the Grundfos pump is "pushing" up, the water is also "dropping" down. Just make sure to get rid of ALL of air in your return line and design your system so that no air will be in your line.



Typical hot water system before a recirculation pump.
Common recirculation pump installation.
Close-Up of pump installation.

Notes on installation:
Now that you're going to have hot water in your pipes all the time we strongly recommend insulating your hot water pipes as well as the return line to avoid stand-by heat loss.
A 2" clearance should be kept between the hot and cold water lines.

Branches off of the main hot water supply should be kept as short as possible.

Local codes may require the installation of a hot water expansion tank for secondary pressure relief on cold water supply lines with check valves.
The pump should be installed with the motor shaft horizontal.
It is very important that there is no trapped air in the pipe or the pump. Unless you have extremely oversized the pump (which wastes a lot of energy), trapped air in the return line can damage the recirculation pump. With these Grundfos recirculating pumps, air removal from the pump can be accomplished by releasing air from the chrome slotted plug located on the front of the pump. IMPORTANT: This chrome plug must NOT be removed. This chrome slotted plug is to release air from the pump only, not from the entire circulation piping system. After the system is charged with water make sure the power to the pump is turned off. Position a bucket under the pump because water will begin to stream from the plug as the air is released. Slowly unscrew the chrome slotted plug counter clockwise, until small bubbles of air and water appear. As soon as tiny bubbles or water appear, stop unscrewing the chrome plug any further. Allow all the air to escape. When only water streams slowly out of the pump then you will know the air has been purged. Tighten the chrome slotted plug clockwise. To prevent air from collecting in the return line, slope all the pipes so air will flow to the high point in the return line and then put an air vent there so you can release the air periodically.
The return line can be installed either under the floor or in the ceiling.
