Circulating Pumps - Grundfos

Grundfos offer a comprehensive range of products that will enable you to install the ultimate technology throughout the entire home. Whether this involves macerators, heating, water supply, water boosting, drainage, rainwater harvesting and submersible applications – with Grundfos you can be sure that the solution will deliver the optimal pump solution.

UPS2

The UPS2 is the ideal product for the replacement of small heating circulator designs which are currently installed in heating systems with limited space and which do not meet the current efficiency levels as stipulated under the EuP directive.

The UPS2 is fitted with modern motor technology and electronic control which enables it to meet an EEI value greater than or equal to 0.23. The UPS2 is designed therefore to meet the efficiency levels as stipulated in the EuP directive for both 2013 and also for the future requirement in 2015.

The UPS2 has been designed to fit into a location where a Grundfos UPS15-50 or UPS15-60 model is currently located.

The UPS2 can also be delivered as a pump head only. This allows an installer the option to change a pump where it is too difficult to remove the complete unit from the system.

Alpha

ALPHA2 is the latest and most innovative member of the Grundfos family of high-quality circulators. With ALPHA2, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT. ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand.

Applications

The GRUNDFOS ALPHA2 is designed for circulating liquids in heating systems. Pumps with stainless steel pump housings can also be used in domestic hot-water systems. The GRUNDFOS ALPHA2 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.

 Features and benefits

  • 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.

Magna

With the addition of the MAGNA1 range Grundfos can now deliver the required high energy efficiency, but with a reduced set of features. These pumps can offer the perfect solution in a refurbishment situation where you need to either replace a Grundfos UPS product or one of the smaller models from the original Magna family. These pumps are designed for circulating liquids in heating systems with variable flows where it is desirable to optimise the settings of the pump duty point, thus reducing energy costs.

The MAGNA1 range of circulators comes complete with electronically controlled motors that are based on permanent magnet (PM) and stator technology. They are designed for circulating liquids in a wide range of light commercial and commercial applications including:

  • Heating systems
  • Air conditioning and cooling systems
  • Domestic water systems
  • Ground-source heat pump systems
  • Solar heating systems

Features:

  • Proportional pressure control
  • Constant pressure control
  • Constant curve/constant speed duty
  • No external motor protection required
  • Insulating shells are supplied with single head pumps for heating systems
  • Wide temperature range where the liquid temperature and the ambient temperature are independent of each other.

 Benefits:

  • Simple installation
  • Low energy consumption – all MAGNA1 pumps comply with EuP 2013 and 2015 requirements
  • Nine possible pump setting
  • Low noise level
  • Minimal maintenance and long life
  • Range is available for a maximum system pressure of 16 bar (PN16)
