  1. Grundfos TPE3 D 80-120 S-A-F-A-BQQE-GAB Inline Twin Head Circulator Pump - 240v - Single Phase

    99272535

    Grundfos - TPE3 D 80-120 S-A-F-A-BQQE-GAB Inline Twin Head Circulator Pump - 240V - Single Phase - Cast Iron

    TPE3 D 80-120 S-A-F-A-BQQE-GWB

    Single-stage, close-coupled, volute twin-head Pump with in-line suction and discharge ports of identical diameter. The twin-head Pump is engineered with two parallel power-heads. The Pump is of the top-pull-out design, i.e. the power head (motor, Pump head and impeller) can be removed for maintenance or service while the Pump housing remains in the pipework. Each power head is equipped with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. Pipework connection is via PN 10 DIN flanges (EN 1092-2 and ISO 7005-2). Each power head is equipped with a fan-cooled, permanent-magnet synchronous motor of identical size. Each power head is equipped with a fan-cooled asynchronous motor of indentical size. The motor performance is classified as IE5 in accordance with IEC 60034-30-2. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable management of the motor speed, which again enables adaptation of the output to a given requirement. The Pump is equipped with temperature- and differential pressure sensors.

    • Suitable for Commercial heating, Commercial air conditioning, District heating, District cooling, Industrial heating, Industrial cooling, Desalination, Drinking water treatment, Water distribution, Irrigation, Community water supply
    • This product's housing material is Cast Iron
    • The impeller is manufactured from Composite
    • Maximum operating pressure: 10 Bar.

  10. Grundfos Magna3 50-120F 97924284 Variable Speed Circulator

    Gr-97924284

    Grundfos - Magna3 50-120F 97924284 Variable Speed Circulator - 230V - Stainless Steel

    MAGNA3 50-120 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.

Heating Circulators

Heating Circulators

Heating circulator pumps keep hot water moving through radiators, baseboards, and underfloor heating systems. They ensure your heating system delivers warmth quickly, reduces waiting times for hot water, and keeps energy use under control.

 

Whether used individually or in combination, circulator pumps can serve multiple zones, giving precise control over each area of your property. In multi-zone systems, one circulator can serve all areas using control valves for each section, or you can fit a dedicated pump to each zone for precise, independent flow.

 

Modern circulators save significant power while maintaining consistent flow. Pumpify offers a range of trusted models from big name brands that are built for durability, smooth operation, and long-lasting performance, helping you get the most out of your heating system.
