The Grundfos UP 20-30 N 150 circulator pump is a robust and efficient solution designed for hot water recirculation and heating applications in commercial buildings. This canned rotor pump is ideal for systems requiring reliable, maintenance-free performance, thanks to its advanced design and durable materials.
Main features:
- Canned rotor design: The Grundfos UP 20-30 N 150 features a canned rotor motor, meaning the pump and motor form a single unit without a shaft seal and only two gaskets for sealing. This minimises the risk of leaks and simplifies maintenance.
- Self-lubricating bearings: The pump's bearings are lubricated by the pumped liquid itself, reducing wear and eliminating the need for frequent maintenance.
- Durable construction: The pump body is made from stainless steel AISI 304 (EN 1.4301), ensuring corrosion resistance and durability in demanding environments. Additionally, the impeller is made from fibreglass-reinforced composite, providing extra strength.
Key technical data:
- Nominal flow rate: 1.53 m³/h, ensuring adequate flow for hot water recirculation in commercial systems.
- Nominal head: 1.7 metres, providing sufficient pressure to ensure effective water distribution in heating or hot water recirculation systems.
- Liquid temperature range: The pump can handle liquids with temperatures from 2 °C to 110 °C, making it suitable for both heating systems and hot water recirculation.
