Figure 1: Pedrollo PLURIJET M4/80-N Self-Priming Multi-Stage Water Pump. This image shows the overall design of the pump, highlighting its compact and robust construction.
2. Caratteristiche tecniche
- Completely renewed range with a new design.
- Improved hydraulic performance for higher efficiency.
- Consumo energetico ridotto.
- One of the quietest models in the centrifugal pump series.
- Enhanced priming capabilities.
3. Installazione e utilizzo
The PLURIJET pumps are suitable for use with clean water, even when air is present, and with liquids that are not chemically aggressive towards the materials from which the pump is made. Due to their quietness, reliability, and low energy consumption, they are recommended for domestic and civil applications such as water supply systems, pressure boosting, and irrigation.
3.1. Application Limits
- Liquid temperature: from -10 °C to +40 °C
- Ambient temperature: up to +40 °C
- Manometric suction lift: up to 9 m (HS)
- Pressione massima di esercizio: 6 bar
- Servizio continuo: S1
4. Impostazione
Proper setup is crucial for optimal performance and longevity of the pump. Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and frost.
4.1. Connessione elettrica
Connect the pump to a single-phase 230 V, 50 Hz power supply. Ensure the electrical installation complies with local regulations and safety standards. The power cable is not included and must be appropriately sized for the pump's power requirements (0.55 kW / 0.75 HP).
4.2. Collegamento idraulico
Connect the suction and delivery pipes to the pump's threaded ports. Ensure all connections are watertight to prevent air ingress, which can affect priming and pump performance. Use appropriate sealants and fittings.
4.3. Adescamento della pompa
Before first use, or after any period of disuse, the pump must be primed. Fill the pump body completely with clean water through the dedicated filling port until water overflows. Close the filling port securely before starting the pump.
5. Istruzioni per l'uso
Once installed and primed, the pump is ready for operation. Ensure the suction line is submerged in water and free from obstructions.
5.1. Avviamento della pompa
Switch on the power supply to the pump. The pump will begin to draw water. Monitor the pressure gauge (if installed) to ensure proper operation. The pump is designed for continuous service (S1).
5.2. Arresto della pompa
To stop the pump, switch off the power supply. For prolonged periods of disuse, especially in freezing conditions, drain the pump completely to prevent damage.
6. Manutenzione
Una manutenzione regolare garantisce la longevità e il funzionamento efficiente della vostra pompa Pedrollo.
6.1. Controlli di routine
- Periodically check for leaks around connections.
- Ensure the pump is free from excessive vibration or unusual noises.
- Verify that the ventilation openings on the motor are clear.
6.2. Preparazione per l'inverno
In areas subject to freezing temperatures, drain the pump and associated piping completely to prevent damage from ice expansion. Store the pump in a dry, frost-free location if possible.
7. Risoluzione Dei Problemi
This section provides solutions to common issues you might encounter with your pump.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| La pompa non si avvia | No power supply, motor overload, seized impeller | Check power connection and circuit breaker. Allow motor to cool. Inspect impeller for obstructions. |
| La pompa funziona ma non eroga acqua | Pump not primed, air leak in suction line, suction lift too high, clogged suction filter | Re-prime the pump. Check all suction connections for leaks. Verify suction lift is within limits. Clean suction filter. |
| Flusso o pressione ridotti | Partial blockage, worn impeller, air in system | Check for blockages in pipes. Inspect impeller for wear. Bleed air from the system. |
| Rumore o vibrazioni eccessivi | Cavitation, foreign object in pump, worn bearings | Ensure adequate water supply to prevent cavitation. Inspect pump for foreign objects. Contact service for bearing replacement. |
