  Circulating Liquids In Heating SystemsCirculator pumps for circulation of hot water in central and district heating systems and circulation in domestic hot water service systems. Circulating pumps are also used for circulation of cold water and other liquids in cooling and air conditioning systems. To get more information please expand the product block by pressing on image or product title. To get detailed information about specific product you can download Technical datasheet file by clicking corresponding link. ALPHA 2 PumpsWith ALPHA 2, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT. ALPHA 2 |  | | ALPHA 2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand. |
The Grundfos ALPHA 2 is suitable for: - Systems with constant or varying flows where it is desirable to optimise the pump duty point
- Systems with a varying flow-pipe temperatures
- Systems where night setback is required
Highlights - Compact design, with control box well integrated into the pump head
- AUTOADAPT control mode as the default setting, suitable for most applications
- Integrated differential pressure control (proportional and constant pressure control)
- Display showing actual power consumption (P1) in Watts
- Low noise
- High starting torque
- Automatic night setback
- Motor based on permanent-magnet/compact-stator technology
- Integrated frequency converter
- Self-venting pump housing

UPS PumpsThe pumps can be used in both open and closed systems. UPS pumps are of the canned-rotor type, i.e. pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. Series 100 And 200 |  | | UPS pumps are designed for circulation of liquids in heating and air-conditioning systems. Pumps with bronze or stainless steel housings are also suitable for use in hot-water service systems. |
Highlights - Maintenance-free
- Low noise
- Low energy
- Complete range
- Available with corrosion-resistant stainless steel or bronze pump housing
- Wide range of accessories
