Overview
The Grundfos ALPHA1 is a high efficiency circulator, designed for pumping liquids in heating and hot water systems. It offers the flexibility to cover 5 or 6m applications with one pump.
The ALPHA1 is an economic choice, reaching the highest possible energy savings in contrast to older technology fixed speed pumps. This is acheived by its permanent magnet motor technology, which can be as low as 4 watts which can be seen on the LCD power display.
The variable speed modulating modes allow the pump to match its performance to the system requirements, helping to reduce noise when thermostatic valves are closing. Noise/heat insulation shells are supplied as standard.
- Intuitive one-button operation makes selection of any control mode simple
- No external motor protection required reducing installation time
- High-torque start improves start-up under harsh conditions
- Maintenance free and noiseless due to canned-rotor design and use of robust components
- Alpha plug makes electrical installation quick, safe and easy
- Insulating shells are supplied with pumps to minimize heat loss in heating systems
- Automatic de-blocking with robust start-up function
