The motor is a 1-phase motor. No additional motor protection is required.

Suitable for: Commercial heating, Domestic heating, Domestic hot water recirculation

ALPHA3 15-50/60 130

Grundfos ALPHA3 high-efficiency circulator pumps are designed for circulating liquids in heating systems. With an energy efficiency index (EEI) well below the ErP benchmark, they ensure substantial energy savings.

ALPHA3 is completely controlled with Grundfos GO Remote via Bluetooth, which gives you step-by-step assistance to pump configuration, maintenance and commissioning, including:

The pump features radiator and underfloor-heating control modes with AUTOADAPT, which continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and changing heat demand during the year. The AUTOADAPT feature finds the setting that provides optimal comfort with minimal energy consumption and makes the commissioning fast, safe, and straightforward. ALPHA3 also offers proportional-pressure, constant-pressure and constant-curve control modes with setpoint adjustment anywhere between the maximum and minimum curve of the chosen setting.

Furthermore, ALPHA3 can communicate directly with the Grundfos GO Balance app, enabling installers to easily perform hydronic balancing of radiator and underfloor-heating systems. ALPHA3 is furthermore compatible with ALPHA Reader and the Grundfos GO Balance app, enabling the installers to easily perform hydronic balancing of radiator and underfloor-heating systems.

With the self-operating night setback function, the pump automatically changes between normal duty and night setback. The changeover depends on the flow-pipe temperature controlled by the heating appliance.

The design and the chosen materials of the pump contribute to long life. The pump is self-venting through the system, which contributes to straightforward commissioning. The space-efficient design, featuring a pump head with an integrated control box, fits into most common installations. Pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These constructional features ensure maintenance-free operation.

The active dry-running protection feature protects the pump against dry running during startup and normal operation. In case of a blocked rotor, the pump will continuously attempt to restart with highest possible torque.

Pump housings made of Cast Iron are electrocoated to improve corrosion resistance. The motor is a synchronous permanent-magnet/space-efficient-stator motor characterised by high efficiency. The pump speed is controlled by an integrated frequency converter incorporated in the control box.

Insulating shells are supplied with pumps to minimise heat loss in heating systems.

Suitable for: Commercial air conditioning, District heating

UPS3 15-50/65 130

High-efficiency canned-rotor circulator designed for circulating liquids in domestic heating systems. appropriate as stand-alone or integrated circulator pump in existing systems, as replacement or in new heating systems.

The pump features three control modes:

Furthermore, the speed can be controlled by a low-voltage PWM (Pulse Width Modulation) profile A – Heating.

Additionally, the straightforward and user-friendly one-button interface makes replacement and settings uncomplicated and fast.

LEDs indicate the actual operating status as well as warnings and alarms

The design of the pump and chosen materials contribute to a long service life. The pump is self-venting through the system, which contributes to straightforward commissioning. The space-efficient design, featuring a pump head with an integrated control box, fits into most common installations as well as boilers due to the ambient temperature range. Pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These design features ensure maintenance-free operation. Servicing screw accessible from the front allows for straightforward access to the pump shaft if deblocking of the pump is required once it has been installed.

The pump housing is made of Cast Iron. The pump housing is electrocoated to improve corrosion resistance.

The motor is a synchronous permanent-magnet motor characterised by high efficiency. Pump speed is controlled by an integrated frequency converter incorporated in the control box.

The benchmark for the most high-efficiency circulators is EEI ≤ 0.20.

Suitable for: Commercial heating, District heating, Domestic heating

High-efficiency pump WILO-Yonos PICO-D, electronically controlled. Glandless twin-head pump with screwed connection, blocking-current proof synchronous motor according to ECM technology and built-in electronic performance control for variable differential pressure control. can be utilised for all heating and air-conditioning applications.
