    Grundfos - GT-H-8-V Vertical Diaphragm Tank - 10 Bar. - 8Ltr

    Grundfos GT-H are maintenance-free multi-purpose pressure tanks with a capacity ranging from 2 to 100 litres.
    The tanks are designed for a maximum operating pressure between 10 and 16 bar and a maximum liquid temperature of 90 °C.

    The tank is a steel pressure tank made of a virgin propylene liner. The tanks have a non-replaceable FDA-approved high-grade butyl diaphragm, which is pre-charged with compressed nitrogen (1.9 bar).

    To ensure long-lasting durability, the diaphragm and liner are both reinforced in specific wear areas. All internal parts, including the air valve, are rounded to prevent piercing of the diaphragm in extreme conditions. The water connection uniquely provides a dual water and air seal ensuring a completely leakage-free pressure tank. Combined with booster and irrigation systems as well as thermal expansion and hydraulic hammer arrestors, the tank is appropriate for drinking-water and grey-water applications. It provides optimised comfort and a patented stainless-steel water connection. The tank also features:

    • replaceable tank base
    • leakage-free air valve sealed with O-ring
    • two-part polyurethane-primed paint finish
    • reinforced connection plate on inline models of 8 litres and above

  14. 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

    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.
