    60214770

    DAB - DKLP 40-1600/BQQE In-Line Circulator Twin Pump IE3 - 3x230/400V - Three Phase - 16m Head

    Product Applications

    An in-line circulator pump engineered for circulating hot or cold water. This product is manufactured by Dab. Appropriate for installation directly onto the pipework of civil and industrial heating, air conditioning, refrigeration and sanitary water systems.

    Construction Features Of The Pump

    Pump body and motor support in Cast Iron.
    PN 10 flanged suction and delivery ports with threaded holes for control manometers. To make replacement in existing systems easier, the pump can accept PN 6 counter flanges.
    Technopolymer impeller. Carbon/ceramic mechanical seal.
    The pumps are available both in the single (KLM-KLP) and in the twin (DKLM-DKLP) versions.
    For the twin version, a built in clapet valve in the delivery port is also included, to avoid water recirculation when the unit is idle. A blind flange is also supplied as a standard, to be applied during maintenance of one of the two motors.
    The twin version gives the possibility of alternating the operation of the pumps when a backup unit is required, or to have the two pumps operating simultaneously.

    Construction Features Of The Motor

    External ventilation cooling, closed, asynchronous type, with four poles for the KLM and DKLM versions, and two poles for the KLP and DKLP versions.
    Rotor running on permanently lubricated ball bearings, oversized to ensure low noise and durability.
    Standard built-in thermo-amperometric protection. Capacitor permanently fitted on single phase versions.
    For the protection of the three-phase motor, we recommend the use of remote overload cut-outs, in compliance with current local regulations.
    Construction according to CEI 2-3.
    Protection class: IP 55
    Insulation class: F
    Standard voltage: single-phase 220-240 V, 50 Hz - three-phase 230/400 V, 50 Hz

  4. Grundfos Magna3 32-120F Variable Speed Circulator

    GR-97924259

    Grundfos - Magna3 32-120F Variable Speed Circulator - Stainless Steel

    MAGNA3 32-120 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.

    Suitable for: Commercial heating

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.

    Suitable for: Commercial heating

  15. Grundfos Magna3 50-150F Variable Speed Circulator Pump

    Gr-97924285

    Grundfos - Magna3 50-150F Variable Speed Circulator Pump - 230V - Stainless Steel

    MAGNA3 50-150 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.

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.
