GRUNDFOS ALPHA2

Overview

Overview

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.

Optimisation

Grundfos offers an efficiency analysis of your existing pump system, providing you with suggestions for increasing efficiency and thus for achieving cost savings over time.

Increase the efficiency of your existing system

Conducting an efficiency analysis of your existing pump system provides you with a basis for increasing efficiency and thus for achieving cost savings over time. An efficiency analysis results in suggestions for increasing efficiency and will show how this will save you money.

Grundfos offers the following levels of analysis for assessing the efficiency of your pump system:

  • Installed base checks.

 

A basic evaluation is carried out purely on the basis of the data from the identification plate on the pump, comparing its performance with that offered by newer, more efficient technology and materials found in modern pumps.

  • Pump efficiency quick check.

 

Pressure and the consumption of the pump in kWh are measured. Flow is estimated on the basis of available pump data and the results of the measurements.

Some of the resulting suggestions for improving efficiency might include a speed control upgrade, a motor upgrade, differently dimensioned pipes, the installation of a controller, or perhaps an agreement for routine service.

Complete pump audit

The efficiency analysis offered by Grundfos makes up the first step in our Pump Audit, a diagnostics tool that we use to check whether the pump system is operating at the optimal energy consumption to guarantee that your costs are kept to an absolute minimum – now and in the future. See "Replacement analysis" to find out more about the Grundfos Pump Audit.

Repair and maintenance

Grundfos Service can advise you on efficiency issues, offering suggestions for saving money in the long term.

Not all our products need spare parts. Our pumps are designed to provide low energy consumption and the highest possible performance throughout their lives. For some pumps, the greatest efficiency and reliability are achieved by replacing worn-out pumps rather than repairing them.

Naturally, you can always call Grundfos for repair and maintenance of pumps you have purchased from us. It is important to remember that an upgrade or even a replacement pump can be cheaper than repair in the long term.

Effective service – wherever you are

Grundfos Service is always close by. Working in collaboration with our local authorised service partners we offer worldwide service. Help from qualified pump professionals is never far away, whether you need immediate assistance or are interested in hearing about opportunities for making savings.

Grundfos Remote Management

Grundfos Remote Management is a cost-effective, secure and reliable way to monitor and manage pump installations from an Internet PC at a very low cost.

Connecting pumps and people

With a secure and reliable remote management system, you can monitor and manage your pump systems from an Internet PC at a very low cost.

Grundfos Remote Management is a cost-effective and straightforward system for monitoring and managing pump installations in commercial buildings and in water supply and wastewater systems. It reduces the need for onsite inspections, and in the event of an alarm or warning, the relevant people are notified directly.

The system offers a wider range of benefits and functions than mobile-phone-based monitoring. For those who do not require remote process automation, Grundfos Remote Management is the ideal solution for monitoring and remote control, rather than traditional SCADA (Supervisory Control and Data Acquisition) systems. Initial investment is minimal, and a fixed low fee covers data traffic, hosting costs and system support, including back-up of all data.

Efficient alarm management

The on-call schedule in this new telemetry system ensures that alarm messages from onsite controllers go directly to the relevant people. The system manager can log on from a PC anywhere and plan who is to receive alarm messages from each installation at any given time of the day. Managers can plan for years ahead, and can easily handle day-to-day exceptions to the schedule.

Optimise service and maintenance

Changes in pump performance can be tracked using trend graphs generated automatically by the system. This tracking can give an indication of any wear or damage in the installation, and service and maintenance can be planned accordingly.

The communication interface (the CIU271 modem) enables data transmission via GPRS/SMS from your Grundfos pumps and controllers. The built-in multi-purpose I/O board allows you to connect sensors and switches.

Replacement

Replacement

Grundfos replacement programme

Grundfos has a comprehensive replacement list for central heating circulator pumps, hot water pumps and wastewater S pumps. You can access a replacement list in SAP by clicking on the "Replacement" button at the top of the screen. After selecting the manufacturer of the pump you want to replace, you can make a pre-selection by entering a type designation, pipe connection or built-in length.

Depending on local availability, distance pieces are also included if the existing pump has a longer built-in length than the new pump.
Any special conditions to be taken into account in replacing the pump will be displayed by pressing the "Information" button in the bottom left-hand corner.

CAPS

The purpose of CAPS is to provide a complete tool that contains both an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application.

There is also a comprehensive pump replacement selection function for central heating circulator pumps, hot water pumps and wastewater S pumps, and a function for producing professional quotations that include curves, drawings, quotation texts, wiring diagrams, etc.

Last but not least, the software contains the instruction and operating manuals for nearly all Grundfos pumps in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types.

CAPS is available in two versions: WinCAPS, available on CD-ROM, and the online version WebCAPS, available at the Grundfos website. Additional features available in WebCAPS include CAD Drawings and Literature.
