This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Grundfos 96402834 UPS 50-80/2 F 200 Series Circulator Pump. Please read these instructions carefully before installing or operating the pump to ensure proper function and longevity.
2. Ọja Ipariview
The Grundfos UPS 50-80/2 F 200 Series Circulator Pump is a canned rotor type pump, designed for circulating liquids in heating and air-conditioning systems. The pump and motor form an integral unit without a shaft seal, with the bearings lubricated by the pumped liquid. This design minimizes maintenance and simplifies disposal. Key features include a 3-speed motor, ceramic radial bearings, carbon axial bearings, a stainless steel rotor can, bearing plate, and rotor cladding, an aluminum alloy stator housing, and a cast iron pump housing. The stator includes a built-in thermal switch for protection. The motor is a 1-phase motor, and the pump is supplied with a standard module in the terminal box for connection to the main supply via an external contactor.

Before initial startup, ensure the system is filled with liquid and properly vented to prevent dry running.
5.1 Yiyan Iyara
The pump is equipped with a 3-speed motor, allowing you to adjust the performance to match system requirements. The speed selector is typically located on the motor housing. Refer to the markings on the pump for specific speed settings (e.g., I, II, III or 1, 2, 3) and their corresponding flow rates or head pressures. Select the desired speed by rotating the selector switch.
5.2 Ibẹrẹ Ibẹrẹ
- After filling the system, switch on the power supply to the pump.
- The pump will start circulating the liquid. Listen for any unusual noises, which may indicate air in the system.
- If necessary, vent the pump by carefully loosening the vent plug (if present) until water flows out, then retighten.
6. Itọju
The Grundfos UPS 50-80/2 F 200 Series Circulator Pump is designed for minimal maintenance due to its canned rotor design where the bearings are lubricated by the pumped liquid. However, periodic checks are recommended.
