1. Introduktion
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Pedrollo UPm2/4-GE Multi-Stage Submersible Electric Water Pump. Please read this manual thoroughly before installation and use, and retain it for future reference.
The Pedrollo UP series of multi-stage submersible pumps features an innovative design that prevents impellers from blocking, even after extended periods of inactivity. This design ensures high efficiency and reliability, making these pumps suitable for clean water applications in domestic, civil, and agricultural settings. Typical uses include water distribution with pressure sets, garden and allotment irrigation, and pressure boosting.
2. Sikkerhedsoplysninger
Overhold altid følgende sikkerhedsforanstaltninger for at forhindre personskade og beskadigelse af pumpen:
- Sørg for, at strømforsyningen passer til pumpens volumentage krav (240V).
- Afbryd strømmen, før du udfører installations-, vedligeholdelses- eller reparationsarbejde.
- Do not operate the pump with damaged cables or if the pump itself is visibly damaged.
- The pump is designed for clean water only. Do not use it for flammable, corrosive, or abrasive liquids.
- Ensure proper grounding of the electrical system.
- Keep children and unauthorized personnel away from the pump's operating area.
- Do not lift the pump by its electrical cable. Use a rope or chain attached to the pump's lifting eye.
3. Opsætning og installation
Proper installation is crucial for the pump's performance and longevity. Refer to the diagram below for a typical installation setup.
Figur 1: Typical installation diagram, performance curves, and dimensional data for Pedrollo UPm2/4-GE submersible pumps. This image illustrates how the pump should be submerged in a water source, connected to a discharge pipe, and includes technical specifications and performance characteristics.
- Nedsænkning: The pump must be fully submerged in clean water. Ensure the water level is always above the pump's intake.
- Montering: Secure the pump using a suitable rope or chain attached to the designated lifting point. Do not let the pump rest directly on the bottom if it's muddy or sandy.
- Afgangsrør: Connect a discharge pipe of appropriate diameter to the pump's outlet. Ensure all connections are watertight.
- Elektrisk tilslutning: Connect the pump to a 240V power supply with proper grounding and a residual current device (RCD) for safety. Consult a qualified electrician if unsure.
- Flydekontakt: If equipped with a float switch (as shown in Figure 1), ensure it can move freely to control the pump's on/off cycles based on water level.
4. Betjeningsvejledning
Once installed correctly, operating the Pedrollo UPm2/4-GE pump is straightforward:
- Indledende opstart: Ensure the pump is fully submerged and all connections are secure. Turn on the power supply. The pump will start automatically if the float switch is in the 'on' position (water level high enough).
- Kontinuerlig drift: The pump is designed for continuous operation within its specified limits. Monitor the water level to prevent dry running, especially if not using a float switch.
- Nedlukning: To stop the pump, turn off the power supply. If using a float switch, the pump will stop automatically when the water level drops below the minimum operating level.
- Vandkvalitet: The pump is intended for clean water. Pumping water with excessive sediment or debris can damage the impellers and motor.
5. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid. Afbryd altid strømmen før vedligeholdelse.
- Rensning: Periodically inspect the pump's intake screen for blockages from debris. Clean as necessary.
- Inspektion af impeller: While the pump's design resists blocking, occasional inspection of the impellers for wear or damage is recommended, especially if performance degrades. This typically requires professional service.
- Kabelinspektion: Check the power cable for any signs of damage, cuts, or fraying. Replace immediately if damaged.
- Vinterisering: In freezing climates, remove the pump from the water source and store it in a frost-free environment if it will not be used during winter. Drain all water from the pump and pipes.
6. Fejlfinding
Hvis du støder på problemer med din pumpe, kan du se følgende almindelige problemer og løsninger:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pumpen starter ikke | No power; Float switch in 'off' position; Motor overload; Damaged cable. | Check power supply and circuit breaker; Ensure float switch is free and water level is sufficient; Reset thermal overload protector (if present); Inspect and replace cable if damaged. |
| Pumpen kører, men intet vand eller lavt flow | Intake blocked; Air in system; Discharge pipe blocked or kinked; Low water level; Worn impellers. | Clean intake screen; Bleed air from the system; Check and clear discharge pipe; Ensure pump is fully submerged; Contact service for impeller inspection. |
| Pumpen stopper uventet | Overheating; Low water level (float switch activated); Electrical fault. | Allow pump to cool; Check water level; Inspect electrical connections and power supply. |
If troubleshooting steps do not resolve the issue, contact a qualified technician or Pedrollo customer support.
