  4. Grundfos Alpha3 15-50/60 Domestic Circulator - 130mm - 240v

    GR-99371966

    Grundfos - ALPHA3 15-50/60 Domestic Circulator - 130mm - 240V - Cast Iron

    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:

    • Warning and alarm status
    • Pump venting process
    • Scheduling for when the pump should operate incl. summer mode
    • Operating and control modes

    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

  5. Grundfos UPS3 15-50/65 Domestic Heating Circulator - 130mm - 240v

    99199622

    Grundfos - UPS3 15-50/65 Domestic Heating Circulator - 130mm - 240V - Cast Iron

    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:

    • constant-curve mode with three settings
    • proportional-pressure control with two settings
    • constant-pressure control with two settings

    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.

    MAGNA3 40-100 F

    The Grundfos MAGNA3 circulator pump is the well-suited choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, MAGNA3 is well-suited for engineers and specifiers looking to create high-performance heating and cooling systems. The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. MAGNA3 features an intuitive display and allows you to connect wirelessly with the Grundfos GO Remote app, giving you access to enhanced reporting and monitoring. MAGNA3 model E has Bluetooth, which allows you to connect directly to the Grundfos GO app on your smart phone without any need for a dongle. The pump includes fieldbus communication via CIM modules as well as analogue and digital inputs and configurable relays. Control features include AUTOADAPT and FLOWADAPT. FLOWADAPT reduces the need for throttling valves, thus cutting costs on system components. MAGNA3 is the superior choice for a wide range of heating and cooling applications, including:

    • small chiller applications
    • ground-source heat pump systems
    • air conditioning surfaces
    • heating surfaces
    • mixing loops
    MAGNA3 is a single-phase pump characterised by the controller and control display being integrated in the control box. The pump also has a built-in differential pressure and temperature sensor. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fibre reinforced, the bearing plate and rotor cladding are made of Stainless Steel and the stator housing is made of aluminium. The power electronics are air-cooled. MAGNA3 incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). This motor type is characterised by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an integrated frequency converter.

Circulating Pumps

Circulating Pumps

Circulating pumps move slurries, liquids, and gases through a closed system, keeping heating, cooling, and hot water circuits flowing as they should. They are most commonly used in domestic and commercial heating systems to maintain a steady supply of hot water, but they also play a key role in underfloor heating, radiator circuits, and chilled water applications.

 

By keeping water moving continuously, circulating pumps help balance temperatures, reduce energy waste, and ensure that taps, showers, and heating systems respond instantly when needed. Hot water circulating pumps are particularly useful in larger properties or commercial setups, where waiting for water to heat can lead to unnecessary water and energy use.

 

At Pumpify, our range includes circulating pumps suitable for everything from simple domestic setups to more complex commercial systems. Designed for easy installation, straightforward maintenance, and long-term performance, these pumps ensure your heating and hot water systems operate smoothly, reliably, and cost-effectively.
