1. Úvod
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your LOWARA BG BGM9/A self-priming centrifugal pump. Please read this manual thoroughly before installation and use, and keep it for future reference. This pump is designed for water distribution, pressure boosting, irrigation, washing, rainwater collection, and use in swimming pools and fountains.
2. Bezpečnostní informace
Always observe the following safety precautions to prevent personal injury and damage to the pump.
- Elektrická bezpečnost: Ensure the power supply matches the pump's specifications (1x220-240V 50Hz). Always disconnect power before performing any maintenance or installation. Use a ground fault circuit interrupter (GFCI) for outdoor or wet applications.
- Instalace: Install the pump in a dry, well-ventilated area, protected from frost and direct sunlight. Ensure stable mounting to prevent vibration.
- Teplota vody: Do not pump liquids outside the specified temperature range (-10°C to +40°C).
- Tlak: Nepřekračujte maximální provozní tlak 8 barů.
- Kvalifikovaný personál: Installation and electrical connections should only be performed by qualified personnel.
- Děti a domácí mazlíčci: Během provozu držte děti a domácí zvířata v dostatečné vzdálenosti od čerpadla.

4. Nastavení
4.1. Umístění
- Position the pump as close as possible to the water source to minimize suction lift.
- Ensure the pump is installed on a firm, level surface to prevent movement and reduce noise.
- Provide adequate ventilation around the pump to prevent overheating.
- Protect the pump from direct weather exposure (rain, snow, direct sunlight) and frost.
4.2. Instalatérské připojení
- Use appropriate pipe sizes for suction and discharge lines to ensure optimal performance and prevent cavitation.
- Install a foot valve with a strainer at the end of the suction line in the water source to prevent debris from entering the pump and to maintain prime.
- Ensure all connections are airtight, especially on the suction side, to prevent air leaks that can affect priming and pump performance.
- Install a shut-off valve on both the suction and discharge sides for easier maintenance.
4.3. Elektrické připojení
- Ověřte, že napájecí zdroj objtage and frequency match the pump's requirements (220-240V, 50Hz).
- Connect the pump to a properly grounded electrical outlet.
- Install a suitable circuit breaker and a ground fault circuit interrupter (GFCI) for protection.
- All electrical work must comply with local regulations and be performed by a licensed electrician.
5. Návod k obsluze
5.1. Naplnění čerpadla
Although the LOWARA BG BGM9/A is a self-priming pump, initial priming is recommended for faster startup and to protect the pump.
- Ensure all valves on the suction and discharge lines are open.
- Remove the priming plug located on the top of the pump body.
- Fill the pump body completely with clean water until it overflows from the priming hole.
- Replace and tighten the priming plug securely.
5.2. Spuštění čerpadla
- Ensure the pump is properly primed and all connections are secure.
- Zapněte napájení čerpadla.
- The pump should start and begin to draw water. If it does not prime within a few minutes, switch it off, check for air leaks, and re-prime.
5.3. Zastavení čerpadla
To stop the pump, simply switch off the power supply.
6. Údržba
Regular maintenance ensures the longevity and optimal performance of your pump. Always disconnect power before performing any maintenance.
- Zkontrolujte netěsnosti: Periodically inspect all connections and seals for any signs of water leakage. Tighten connections as needed.
- Clean Strainer/Foot Valve: If a foot valve with a strainer is installed, regularly check and clean it to prevent blockages and maintain efficient water flow.
- Zima: In areas subject to freezing temperatures, drain the pump completely to prevent damage from ice expansion. Remove the drain plug and allow all water to escape. Store the pump in a dry, frost-free location if possible.
- Kontrola motoru: Ensure the motor's ventilation openings are clear of debris.
7. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Čerpadlo se nespustí | No power, tripped circuit breaker, faulty wiring. | Check power supply, reset breaker, inspect wiring (by qualified electrician). |
| Pump runs but does not prime or deliver water | Air leak in suction line, pump not filled with water, clogged foot valve/strainer, suction lift too high. | Check all suction connections for leaks, re-prime the pump, clean foot valve, ensure suction lift is within limits (max 8m). |
| Nízký průtok nebo tlak vody | Partially clogged strainer, air in system, worn impeller, discharge valve partially closed. | Clean strainer, check for air leaks, inspect impeller (by qualified technician), fully open discharge valve. |
| Čerpadlo je hlučné nebo nadměrně vibruje | Cavitation (air in water), loose mounting, foreign object in pump, worn bearings. | Check for air leaks, secure pump mounting, inspect pump for obstructions, contact service for bearing issues. |
