15. UPS 32-120/2 F 220
16. UPS 32-60/2 F 220

These models vary primarily in terms of their flow rates and head pressures, making them suitable for different system sizes and operational requirements. Each model has a designated flow range, with higher model numbers generally corresponding to higher capacities (e.g., UPS 80-120/2 F 360 can handle higher flow and head pressures than UPS 32-60/2 F 220).

Specifically designed for heating and air-conditioning systems, the UPSD is a twin-head version of the UPS three-speed pump, providing both primary and standby operation to enhance system reliability.

Duty Range (Specifications)

• Maximum Flow: 29 m³/h (cubic meters per hour)
• Maximum Head: 10 meters (the height the pump can push water)
• Liquid Temperature Range: -10°C to 120°C (temperature range of the liquid being pumped)
• Maximum Pressure: 10 bar (the maximum pressure the pump can handle)

Model Variants

• UPSD 50-120 F 280: Likely a larger capacity variant with a higher head and flow.
• UPSD 40-120 F 250: A medium variant with a slightly lower flow and head.
• UPSD 40-60 F 250: A version suited for applications requiring less flow and head.
• UPSD 32-120 F 220: A smaller variant, with the lowest flow and head ratings.

These pumps are typically used in applications where reliability is critical, and having a primary and standby pump can ensure continuous operation even if one pump fails.

The UPS B series circulator pump is designed for efficient and reliable hot-water recirculation, providing optimal performance with various models tailored to different applications.
