Description
High-efficiency recirculation pump model ALPHA1 25-80 180 from Grundfos, designed for the circulation of liquids in heating systems.
Details
More information
High-efficiency circulators, designed for the circulation of liquids in heating systems. With an energy efficiency index (EEI) in line with the ErP benchmark for the most efficient circulators, it contributes to energy savings. They are the ideal choice for basic functionality needs.
Features:
- Intuitive one-button operation simplifies selection of any control mode
- No external motor protection required, thus reducing installation time
- High torque start-up improves start-up under harsh conditions
- Maintenance-free and noise-free thanks to encapsulated rotor design and use of solid components
- ALPHA connector allows for quick and easy electrical installation
- Insulation housings are supplied with the pumps to minimise heat loss in heating systems.
The pump also features three control modes, each with three settings:
- Proportional pressure control
- Constant pressure control
- Constant curve mode
Key features of the ALPHA1 25-80 180 recirculation pump:
- Display shows actual power consumption in watts. LEDs indicate the current operating status.
- The pump has a ceramic shaft and radial bearings, carbon thrust bearing, rotor sleeve, support plate and rotor liner made of stainless steel and impeller made of composite material, all of which contribute to a long service life.
- The pump is self-bleeding throughout the system, which contributes to easy start-up. Its compact design, featuring a pump head with an integrated control box and control panel, is suitable for most common installations.
- The pump housing is made of cast iron and galvanized to improve corrosion resistance.
- The motor is a permanent magnet/compact stator motor, characterized by its high efficiency.
- The pump speed is controlled by an integrated frequency converter, which is built into the control box.
