- Manometric suction lift: up to 9 m (HS)
- Presión máxima de traballo: 6 bar
- Continuous service: S1
4. Configuración
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. Conexión eléctrica
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. Hydraulic Connection
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. Cebado da bomba
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. Instrucións de funcionamento
Once installed and primed, the pump is ready for operation. Ensure the suction line is submerged in water and free from obstructions.
5.1. Arranque da bomba
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. Parada da bomba
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. Mantemento
Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump.
6.1. Comprobacións de rutina
- 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. Preparación para o 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 Solución de problemas
This section provides solutions to common issues you might encounter with your pump.
| Problema | Causa posible | Solución |
|---|---|---|
| A bomba non arranca | No power supply, motor overload, seized impeller | Check power connection and circuit breaker. Allow motor to cool. Inspect impeller for obstructions. |
| A bomba funciona pero non entrega auga | 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. |
| Fluxo ou presión reducidos | Partial blockage, worn impeller, air in system | Check for blockages in pipes. Inspect impeller for wear. Bleed air from the system. |
| Ruído ou vibración excesivos | Cavitation, foreign object in pump, worn bearings | Ensure adequate water supply to prevent cavitation. Inspect pump for foreign objects. Contact service for bearing replacement. |
