Heating Circulator Pumps

GR-97549426
Grundfos - UPS 15-50N Domestic Hot Water Service Pump Circulator - 230V - Stainless Steel
UPS 15-50 N 130
The pump unit is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricatd by the pumped liquid. The pump has 3-step speed selector. The pump is characterized by:

Stainless Steel pump housing
corrosion-protected impeller, Composite
Stainless Steel rotor can and bearing plate
Carbon axial bearing
Ceramic shaft and radial bearings

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

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

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.

Grundfos - TP 32-180/2 0.55kw 2900RPM Commercial Circulator Pump - Single Head - 230V - 0.55kW

TP 32-180/2 A-F-A-BQQE-EW1
Single-stage, close-coupled, volute (centrifugal) pump unit with in-line suction and discharge ports of identical diameter. 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. The pump is equipped with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. All pipework connection is via PN 6/10 DIN flanges (EN 1092-2 and ISO 7005-2). The pump is equipped with a fan-cooled asynchronous motor.

Suitable for: Commercial air conditioning
