Circulation pump UPS 32-80b 1801x230V 95906448

Circulation pump for heating and hot water systems

The Grundfos UPS 32-80b is a canned motor circulation pump designed for forcing liquid circulation in heating, air conditioning and domestic hot water systems. The pump design is based on a combination of the motor and impeller into a single compact unit, eliminating the need for additional shaft seals – only two stationary seals are sufficient. This solution translates into maintenance-free operation and high device reliability. The pump bearings are lubricated by the flowing liquid itself, which further increases its lifespan.

Construction and application

The pump body is made of stainless steel (grade 304 / 1.4308), which ensures corrosion resistance and the possibility of use in various environments. The impeller is made of PES/PP composite, and the shaft and thrust bearing are made of ceramic – these materials guarantee durability and abrasion resistance. The UPS 32-80b pump is perfect for central heating installations, underfloor heating systems, and domestic hot water installations. The ability to connect to a timer allows for optimization of pump operation and reduction of energy consumption.

Key features and benefits

• Durable construction: Stainless steel body and ceramic thrust bearing ensure long pump life, even in harsh working conditions.
• Maintenance-free: No maintenance required thanks to the wet rotor and lubrication of the bearings by the flowing liquid.
• High efficiency: Optimal matching of the motor and pump translates into low electricity consumption.
• Wide range of applications: Can be used in heating, air conditioning systems and domestic hot water installations.
• Quiet operation: The design minimizes noise levels during pump operation.
• Easy installation: BSPP threaded connections facilitate integration with the existing installation (nominal diameter 2 inches / 50 mm).
• Resistance to high temperatures: Continuous operation in the temperature range from -25°C to 110°C.
• Maximum working pressure: 10 bar – ensures safe operation in most installations.
• Power consumption: 220 W at a rated current of 0.98 A – allows for efficient operation while reducing operating costs.
• Installation length: 180 mm – makes it easier to fit into the existing mounting space.

The Grundfos UPS 32-80b pump is a solid and reliable solution for demanding installations that will provide comfortable use for years to come.
