- Ambient temperature: Up to +40°C
- Manometric suction lift: Up to 7 meters maximum
- Maximaler Arbeitsdruck: 7 bar
- Continuous service: S1
2. Sicherheitshinweise
Beachten Sie stets die folgenden Sicherheitsvorkehrungen, um Verletzungen und Schäden an der Pumpe zu vermeiden.
- Ensure the pump is installed by qualified personnel in accordance with local regulations and standards.
- Vor Beginn jeglicher Installations-, Wartungs- oder Reparaturarbeiten die Stromzufuhr unterbrechen.
- Do not operate the pump dry; ensure it is always primed with water before starting.
- Schützen Sie die Pumpe vor Frost.
- Stellen Sie sicher, dass die elektrische Verbindung ordnungsgemäß geerdet ist.
- Die Pumpe darf nicht für brennbare, ätzende oder explosive Flüssigkeiten verwendet werden.
3. Auspacken und Inspektion
- Nehmen Sie die Pumpe vorsichtig aus der Verpackung.
- Inspect the pump for any visible damage that may have occurred during transit. If damage is found, contact your supplier immediately.
- Prüfen Sie, ob alle in der Packliste aufgeführten Komponenten vorhanden sind.
4. Installation
4.1 Mechanical Installation (Plumbing)
- Mount the pump on a solid, level surface to minimize vibration.
- Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and adverse weather conditions.
- Use pipes of adequate diameter to avoid excessive pressure drops. The inlet and outlet connections are 1 inch.
- Install a foot valve with a strainer on the suction line to prevent debris from entering the pump and to maintain prime.
- Ensure all pipe connections are airtight to prevent air leaks, which can affect pump performance.
- Install isolation valves on both suction and discharge lines for easier maintenance.
4.2 Elektrischer Anschluss
- The pump requires a three-phase 400V, 50Hz power supply.
- Electrical connections must be performed by a qualified electrician in compliance with local electrical codes.
- Stellen Sie sicher, dass die Stromversorgung dem Volumen der Pumpe entspricht.tage und Frequenzbewertungen.
- Install appropriate circuit breakers or fuses for motor protection.
- Connect the pump to a properly grounded electrical system.
- Verify the motor's rotation direction. If incorrect, reverse two of the phase wires.

5. Einrichtung
- Vorbereiten der Pumpe: Before initial startup, completely fill the pump casing and the suction line with clean water through the priming port. This is crucial to prevent dry running.
- Auf Lecks prüfen: After filling, inspect all connections for any leaks.
- Power-Check: Briefly turn on the power to check the motor's rotation direction. If the rotation is incorrect (e.g., indicated by a label or arrow on the motor), immediately turn off the power and reverse two of the phase wires.
6. Bedienungsanleitung
- Starten der Pumpe: Ensure the pump is fully primed. Open the discharge valve slightly, then switch on the power. Gradually open the discharge valve completely once the pump is running smoothly.
- Überwachung: During operation, monitor for unusual noises, excessive vibration, or leaks. Ensure the pump is delivering water at the expected flow and pressure.
- Pumpe anhalten: Close the discharge valve, then switch off the power.
- Erweitertes Herunterfahren: If the pump will be out of service for an extended period, especially in freezing conditions, drain all water from the pump and piping to prevent damage.
7. Wartung
Regelmäßige Wartung gewährleistet optimale Leistung und verlängert die Lebensdauer der Pumpe.
- Regelmäßige Inspektion: Periodically check for leaks, unusual noises, or vibrations.
- Sauberkeit: Keep the pump and motor free from dust and debris to ensure proper cooling.
- Foot Valve/Strainer: Inspect and clean the foot valve strainer regularly to prevent blockages.
- Überwinterung: In areas prone to freezing, drain the pump and associated piping completely or protect them from freezing temperatures.
- Professioneller Service: For internal component inspection or replacement (e.g., seals, bearings), consult a qualified service technician.
8. Fehlerbehebung
In diesem Abschnitt werden häufig auftretende Probleme behandelt.
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Pumpe startet nicht | No power supply; Motor overload; Faulty wiring | Check power connection and circuit breaker; Allow motor to cool and reset overload; Inspect wiring. |
| Pump runs but delivers no water | Pump not primed; Air leak in suction line; Suction lift too high; Clogged foot valve/strainer | Prime the pump; Check all suction connections for leaks; Reduce suction lift; Clean foot valve/strainer. |
| Niedriger Durchfluss oder Druck | Partial blockage; Air in system; Worn impeller; Incorrect motor rotation | Check for blockages in piping; Bleed air from system; Inspect impeller (professional service); Verify motor rotation. |
| Übermäßige Geräusche oder Vibrationen | Cavitation (air in water); Loose mounting; Worn bearings | Ensure pump is fully primed and no air leaks; Secure pump mounting; Contact service for bearing inspection. |
