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. സുരക്ഷാ നിർദ്ദേശങ്ങൾ

Always observe the following safety precautions to prevent personal injury and damage to the pump:

• Ensure the pump is installed by qualified personnel in accordance with local electrical and plumbing codes.
• Disconnect power before performing any installation, maintenance, or repair work.
• Do not operate the pump with flammable, corrosive, or explosive liquids.
• പമ്പിനെ തണുത്തുറഞ്ഞ താപനിലയിൽ നിന്ന് സംരക്ഷിക്കുക.
• Ensure proper ventilation around the pump. The ambient temperature should not exceed 40°C.
• Never run the pump dry. This can cause severe damage.
• ഇൻസ്റ്റാളേഷൻ, അറ്റകുറ്റപ്പണികൾ എന്നിവയ്ക്കിടെ ഉചിതമായ വ്യക്തിഗത സംരക്ഷണ ഉപകരണങ്ങൾ (പിപിഇ) ധരിക്കുക.

The single-phase 220V motor includes integrated thermal protection to safeguard the pump against unexpected starts or overheating. The coupling shaft between the impeller and the electric motor is made of INOX EN 10088-3 - 1.4104. The mechanical seal, composed of carbon, ceramic, and nitrile, ensures a tight seal between the pump body and the electric motor.

5. ഇൻസ്റ്റലേഷനും സജ്ജീകരണവും

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. മൗണ്ടിംഗ്

• 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. വൈദ്യുതി ബന്ധം

• വൈദ്യുതി വിതരണം വോളിയം ആണെന്ന് പരിശോധിക്കുകtage 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.
• പമ്പിൻ്റെ ശരിയായ ഗ്രൗണ്ടിംഗ് ഉറപ്പാക്കുക.
• The single-phase motor includes integrated thermal protection. Do not bypass this safety feature.

5.4. പമ്പ് പ്രൈമിംഗ്

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. ഓപ്പറേഷൻ

6.1. പ്രാരംഭ ആരംഭം

• Ensure the pump is properly primed (see Section 5.4).
• Open any isolation valves on the suction and discharge lines.
• പമ്പിലേക്കുള്ള വൈദ്യുതി വിതരണം ഓണാക്കുക.
• Monitor the pump for unusual noises or vibrations. If any occur, switch off immediately and investigate.
• Check for leaks at connections.

6.2. സാധാരണ പ്രവർത്തനം

• 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. പരിപാലനം

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. വാർഷിക അറ്റകുറ്റപ്പണികൾ

• 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. ശൈത്യകാലവൽക്കരണം (ബാധകമെങ്കിൽ)

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.
