1. அறிமுகம்
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. தயாரிப்பு முடிந்துவிட்டதுview
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.

- Connect the pump to the piping system using appropriate GF 50 flanges.
- கசிவுகளைத் தடுக்க அனைத்து இணைப்புகளும் நீர்ப்புகாவாக இருப்பதை உறுதிசெய்யவும்.
- Avoid applying stress to the pump housing from misaligned piping.
4.3 மின் இணைப்பு
- The pump requires a 115V, 60 Hz, 1-phase power supply.
- Connect the standard module in the terminal box to the main supply via an external contactor, as specified in the wiring diagram provided with the pump.
- மின் அபாயங்களைத் தடுக்க சரியான தரையை உறுதிப்படுத்தவும்.
5. இயக்க வழிமுறைகள்
Before initial startup, ensure the system is filled with liquid and properly vented to prevent dry running.
5.1 வேகத் தேர்வு
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 ஆரம்ப தொடக்க
- 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. பராமரிப்பு
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.
- காட்சி ஆய்வு: Regularly inspect the pump for any signs of leaks, corrosion, or damage to the casing or electrical connections.
- சத்தம் சரிபார்ப்பு: Listen for any unusual noises during operation, which could indicate air in the system or a mechanical issue.
- கணினி அழுத்தம்: Ensure the system pressure remains within the recommended operating range.
- சுத்தம்: Keep the exterior of the pump clean and free from dust and debris to ensure proper heat dissipation.
எந்தவொரு பராமரிப்பு அல்லது ஆய்வு செய்வதற்கு முன்பும் எப்போதும் மின்சாரத்தைத் துண்டிக்கவும்.
7. சரிசெய்தல்
Before attempting any troubleshooting, ensure the power supply to the pump is disconnected.
| பிரச்சனை | சாத்தியமான காரணம் | தீர்வு |
|---|---|---|
