ALPHA1 15-50 N 130nGrundfos ALPHA1 pumps are high-efficiency circulators, designed for circulating liquids in heating systems. With an energy efficiency index (EEI) at the ErP benchmark for most efficient circulators it contributes to energy savings. The ideal choice for basic functionality needs.nnFeaturesnnIntuitive one-button operation makes selection of any control mode simplenNo external motor protection required reducing installation timenHigh-torque start improves startup under harsh conditionsnMaintenance free and noiseless due to canned-rotor design and use of robust componentsnALPHA plug makes electrical installation quick, safe and easynInsulating shells are supplied with pumps to minimize heat loss in heating systemsnThe pump also features three control modes – each with three settingsnnproportional-pressure controlnconstant-pressure controlnconstant-curve modenThe display shows the actual power consumption in Watts. LEDs indicate the actual operating status.nnThe pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless-steel rotor can, bearing plate and rotor cladding, composite impeller, all of which contribute to long life. The pump is self-venting through the system, which contributes to easy commissioning. The compact design featuring pump head with integrated control box and control panel fits into most common installations.nnThe pump housing is made of stainless steel for applications where the media requires this, e.g. avoiding corrosion when used in domestic hot-water systems.nnThe motor is a synchronous permanent-magnet/compact-stator motor characterized by high efficiency. The pump speed is controlled by an integrated frequency converter incorporated in the control box.
