Based on the customer's fire pump requirements (10 horsepower, 6.5 liters/second flow rate, 80 meters head, 220V three-phase power), combined with the technician's recommendation for the 50CDL20-40 vertical multi-stage centrifugal pump, the following is a detailed analysis:

 

I. Compatibility Analysis between Requirements and Pump Parameters

 

Power Matching

Customer Requirement: 10 horsepower (approximately 7.5kW)

Pump Parameters: 7.5kW-2p (AC220V 60Hz 3PH), a perfect match.

Conclusion: The power meets the requirements, and the motor uses a three-phase 220V power supply, which is consistent with the customer's power supply.

 

Flow Matching

Customer Requirement: 6.5 liters/second (23.4 m³/h)

Pump Parameters: Rated flow rate 23.4 m³/h, a perfect match.

Conclusion: The flow rate meets the design requirements and no additional adjustments are required.

 

Head Matching

Customer Requirement: 80 meters

Pump Parameters: Head 80 meters, a perfect match.

Conclusion: The head meets the fire system pressure requirements.

 

Voltage and Frequency

Customer Requirements: 220V three-phase power

Pump Specifications: AC220V 60Hz 3PH, fully compatible.

Note: Please confirm whether the power grid frequency in your region is 60Hz (e.g., 50Hz in China). If it is 50Hz, the motor specifications must be adjusted or motor compatibility must be confirmed.

 

II. Other Key Pump Parameters

Speed: 2900 rpm, a standard centrifugal pump speed, ensuring stable operation.

Seal: Mechanical seal, resistant to wear, low risk of leakage, and suitable for long-term operation.

Material:

Pump Head: SS304 stainless steel, corrosion-resistant, suitable for pumping clean water.

Base/Flange: Cast iron, high strength, low cost.

Protection Rating: IP55, dust-proof and waterproof, suitable for fire pump room environments.

Insulation Class: F, excellent high-temperature resistance.

Color: Available in black or red, with red more compliant with fire equipment marking regulations.

 

III. Selection Conclusion

The 50CDL20-40 vertical multi-stage centrifugal pump fully meets customer needs, with the following specific advantages:

 

Precisely matched parameters: Flow rate, head, and power are consistent with customer requirements, eliminating the need for redundant design.

 

Compact structure: The vertical design saves space and is suitable for pump room installation.

 

Reliable materials: Stainless steel pump head and cast iron base offer both corrosion resistance and cost-effectiveness.

 

Motor compatibility: Three-phase 220V 60Hz motor (customer frequency requirements must be confirmed) with a high level of protection.

 

IV. Recommendations and Precautions

Frequency Verification: If the customer's area has a 50Hz power grid, a 50Hz motor must be replaced or motor compatibility must be confirmed.

 

Backup Pump Configuration: According to fire protection regulations, it is recommended to have a backup pump of the same model as the main pump.

 

Self-priming Water Suction: Ensure the pump installation location meets self-priming water suction requirements or equip it with reliable water diversion equipment.

 

Quotation and Delivery: Contact CIXIFM (Winny) for the latest quote and delivery time, and confirm whether taxes, shipping, and installation and commissioning services are included.

 

 

In summary: The 50CDL20-40 is an ideal choice for this customer's needs. We recommend confirming frequency details with the customer as soon as possible and proceeding with the quote process.
