Grundfos ALPHA1 high-efficiency circulation pumps are designed for the circulation of liquids in heating systems. The stainless steel variant of ALPHA1 is suitable for e.g. domestic hot water systems. With an Energy Efficiency Index (EEI) at the ErP benchmark for the most efficient pumps, it contributes to energy savings.
The pump can operate in proportional pressure, constant pressure and constant curve modes. The control mode is selected using the button on the display. The LEDs indicate the operating status, actual energy consumption in watts, as well as warnings and alarms.
The design and selected materials of the pump contribute to the long service life. The pump is self-ventilating throughout the system, which contributes to easy commissioning. The compact design, featuring a pump head with an integrated control box, fits into the most common installations. The pump and motor form an integral unit without mechanical seal. The bearings are lubricated by the pumped liquid. These construction features ensure maintenance-free operation.
The cast iron pump housings are electrically coated to improve corrosion resistance. The motor is a compact stator/permanent magnet synchronous motor with high efficiency. The speed of the pump is controlled by an integrated frequency converter built into the control box.
Insulating shells are supplied with pumps to minimize heat loss in heating systems.
