The single-phase 220V motor includes integrated thermal protection to safeguard the pump against unexpected starts or overheating. The coupling shaft between the impeller and the electric motor is made of INOX EN 10088-3 - 1.4104. The mechanical seal, composed of carbon, ceramic, and nitrile, ensures a tight seal between the pump body and the electric motor.

5. Installation og opsætning
Proper installation is crucial for the pump's performance and longevity. It is highly recommended that installation be carried out by a qualified professional.
5.1. Montering
- Mount the pump on a solid, level, and vibration-free surface.
- Ensure the installation location is dry, well-ventilated, and protected from direct sunlight, rain, and freezing temperatures.
- Allow sufficient space around the pump for ventilation and maintenance access.
5.2. Rørforbindelser
- Brug rør med tilstrækkelig diameter for at minimere friktionstab.
- Install a foot valve with a strainer on the suction line if the pump is not self-priming or if there's a risk of debris.
- Ensure all connections are airtight to prevent air leaks, which can affect priming and performance.
- Support piping independently to avoid stressing the pump's connections.
- Installer afspærringsventiler på både suge- og udløbsledninger for at lette vedligeholdelsen.
5.3. Elektrisk tilslutning
- Kontroller, at strømforsyningen voltage and frequency match the pump's specifications (220V, 50Hz).
- Tilslut pumpen til et dedikeret kredsløb, der er beskyttet af en fejlstrømsafbryder (RCD) og en passende afbryder.
- Sørg for korrekt jording af pumpen.
- The single-phase motor includes integrated thermal protection. Do not bypass this safety feature.
5.4. Priming af pumpen
Before the first start-up, the pump body must be completely filled with the liquid to be pumped. Open the priming plug (if available) or slowly fill the suction line and pump casing until all air is expelled. Close the plug securely.
6. Betjening
6.1. Første opstart
- Sørg for, at pumpen er korrekt primet (se afsnit 5.4).
- Open any isolation valves on the suction and discharge lines.
- Tænd for strømforsyningen til pumpen.
- Monitor the pump for unusual noises or vibrations. If any occur, switch off immediately and investigate.
- Check for leaks at connections.
6.2. Normal drift
- The pump is designed for continuous operation within its specified performance range.
- Avoid running the pump against a closed discharge valve for extended periods, as this can lead to overheating.
- Regularly check the pressure gauges (if installed) to ensure the pump is operating within expected parameters.
6.3. Shut-down
- Sluk for strømforsyningen til pumpen.
- Close isolation valves if the system is to be drained or for maintenance.
7. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid. Afbryd altid strømmen, før du udfører vedligeholdelse.
7.1. Routine Checks (Weekly/Monthly)
- Inspect for any visible leaks around the pump and piping connections.
- Listen for unusual noises or vibrations.
- Check the motor temperature; it should not be excessively hot to the touch.
- Ensure the ventilation openings are clear of debris.
7.2. Annual Maintenance
- Inspect the mechanical seal for wear or leaks. Replace if necessary (requires professional service).
- Check the impeller for any signs of corrosion or damage.
- Clean any strainers or filters in the suction line.
- Verify electrical connections are secure and free from corrosion.
7.3. Vinterklargøring (hvis relevant)
If the pump is installed in an area subject to freezing temperatures and will not be used, it must be drained completely to prevent damage from ice expansion. Disconnect power, open drain plugs, and remove any remaining water from the pump casing og rørføring.
