1. Introducció

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Pedrollo CPM150 centrifugal water pump. Please read these instructions carefully before installing or operating the pump. Retain this manual for future reference.

The Pedrollo CPM150 pump is designed for handling clean liquids with minimal sediment. It is suitable for various applications including industrial liquid recycling (cold or hot), filtration processes, water treatment, and general agricultural or domestic use.

2. Instruccions de seguretat

Observeu sempre les següents precaucions de seguretat per evitar lesions personals i danys a la bomba:

• Ensure the pump is installed by qualified personnel in accordance with local electrical and plumbing codes.
• Desconnecteu l'alimentació abans de realitzar qualsevol treball d'instal·lació, manteniment o reparació.
• Do not operate the pump with flammable, corrosive, or explosive liquids.
• Protegiu la bomba de les temperatures de congelació.
• Ensure proper ventilation around the pump. The ambient temperature should not exceed 40°C.
• Never run the pump dry. This can cause severe damage.
• Utilitzeu l'equip de protecció individual (EPI) adequat durant la instal·lació i el manteniment.

3. Producte acabatview

The Pedrollo CPM150 is a robust centrifugal pump featuring a cast iron pump body with cataphoresis treatment. The impeller is made of INOX AISI 304 stainless steel, and the motor lantern is aluminum. The pump is designed for continuous service (S1).

5. Instal·lació i configuració

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. Muntatge

• 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. Piping Connections

• Use pipes of adequate diameter to minimize friction losses.
• 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.
• Install isolation valves on both suction and discharge lines for easier maintenance.

5.3. Connexió elèctrica

• Comproveu que la font d'alimentació voltage and frequency match the pump's specifications (220V, 50Hz).
• Connect the pump to a dedicated circuit protected by a residual current device (RCD) and appropriate circuit breaker.
• Assegureu-vos de posar a terra correctament la bomba.
• The single-phase motor includes integrated thermal protection. Do not bypass this safety feature.

5.4. Aclarint la bomba

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. Funcionament

6.1. Posada en marxa inicial

• Ensure the pump is properly primed (see Section 5.4).
• Open any isolation valves on the suction and discharge lines.
• Connecteu l'alimentació a la bomba.
• Monitor the pump for unusual noises or vibrations. If any occur, switch off immediately and investigate.
• Check for leaks at connections.

6.2. Funcionament normal

• 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

• Switch off the power supply to the pump.
• Close isolation valves if the system is to be drained or for maintenance.

7. Manteniment

Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before performing any maintenance.

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. Hivernació (si escau)

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 and piping.
