Grundfos - TPED 125-190/4 S-A-F-A-BQQE-NX3 Twin Head In-Line Circulator Pump - 415V - Three Phase - 3753 Ltr/min. - Cast IronTPED 125-190/4 S-A-F-A-BQQE-NW3
Single-stage, close-coupled, volute twin-head pump unit with in-line suction and discharge ports of identical diameter. The twin-head pump is designed 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 fitted with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. All pipework connection is via PN 16 DIN flanges (EN 1092-2 and ISO 7005-2). Each power head is fitted with a fan-cooled asynchronous motor of indentical size. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement. The pump is equipped with a differential pressure sensor.
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

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.
