1. Introduktion
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. Sikkerhedsoplysninger
Overhold altid følgende sikkerhedsforanstaltninger for at forhindre personskade og beskadigelse af pumpen.
- Elektrisk sikkerhed: 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.
- Installation: Install the pump in a dry, well-ventilated area, protected from frost and direct sunlight. Ensure stable mounting to prevent vibration.
- Vandtemperatur: Do not pump liquids outside the specified temperature range (-10°C to +40°C).
- Tryk: Overskrid ikke det maksimale driftstryk på 8 bar.
- Kvalificeret personale: Installation og elektriske tilslutninger bør kun udføres af kvalificeret personale.
- Børn og kæledyr: Hold børn og kæledyr væk fra pumpen under drift.

4. Opsætning
4.1. Placering
- 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. VVS-tilslutninger
- Use appropriate pipe sizes for suction and discharge lines to ensure optimal performance and prevent cavitation.
- Installer en fodventil med en si for enden af sugeledningen i vandkilden for at forhindre snavs i at trænge ind i pumpen og for at opretholde spædningen.
- Ensure all connections are airtight, especially on the suction side, to prevent air leaks that can affect priming and pump performance.
- Installer en afspærringsventil på både suge- og udløbssiden for at lette vedligeholdelsen.
4.3. Elektrisk tilslutning
- Kontroller, at strømforsyningen voltage and frequency match the pump's requirements (220-240V, 50Hz).
- Tilslut pumpen til en korrekt jordet stikkontakt.
- 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. Betjeningsvejledning
5.1. Priming af pumpen
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.
- Fjern spædeproppen, der er placeret øverst på pumpehuset.
- Fill the pump body completely with clean water until it overflows from the priming hole.
- Replace and tighten the priming plug securely.
5.2. Start af pumpen
- Ensure the pump is properly primed and all connections are secure.
- Tænd for strømforsyningen til pumpen.
- 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. Stop af pumpen
To stop the pump, simply switch off the power supply.
6. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer pumpens levetid og optimale ydeevne. Afbryd altid strømmen, før du udfører nogen form for vedligeholdelse.
- Tjek for lækager: 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.
- Vinterisering: 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.
- Motorinspektion: Ensure the motor's ventilation openings are clear of debris.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pumpen starter ikke | No power, tripped circuit breaker, faulty wiring. | Check power supply, reset breaker, inspect wiring (by qualified electrician). |
| Pumpen kører, men den spæder ikke eller leverer vand | 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). |
| Lavt vandflow eller tryk | 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. |
| Pumpen larmer eller vibrerer for meget | 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. |
