The GRUNDFOS UPS 25-40 180 Hot Water Circulation Pump is a reliable wet-rotor circulation pump designed for hot water recirculation and heating system applications in residential and light commercial installations.

Manufactured by Grundfos, this pump is widely used for domestic hot water circulation, radiator systems, and heating loops where continuous and stable water movement is required.

It features a 3-speed motor control system, allowing adjustment of performance based on system demand for improved efficiency and comfort.

The pump operates with a wet rotor design, meaning the motor and pump form a single sealed unit where the pumped liquid lubricates the bearings, ensuring quiet operation and minimal maintenance.

With a 180 mm installation length, it is compatible with standard circulation pump fittings used in heating and hot water systems.

Its durable construction ensures long service life, energy-efficient operation, and reliable performance in continuous circulation applications.
