fire water pump
Here’s a structured and professional response to the customer’s fire pump selection inquiry, incorporating technical validation, practical considerations,
and clear next steps:
Fire Pump Selection Validation: 50CDL20-40 Vertical Multistage Centrifugal Pump
1. Customer Requirements vs. Pump Specifications
| Parameter | Customer Requirement | 50CDL20-40 Specifications | Match Status |
|---|---|---|---|
| Power | 10 HP (~7.5 kW) | 7.5 kW-2p (AC220V, 60Hz, 3PH) | Exact Match |
| Flow Rate | 6.5 L/s (23.4 m³/h) | 23.4 m³/h | Exact Match |
| Head | 80 meters | 80 meters | Exact Match |
| Voltage/Phase | 220V three-phase | AC220V, 3PH | Exact Match |
| Frequency | Not specified (assume 50Hz/60Hz) | 60Hz (verify compatibility) | Needs Confirmation |
Key Validation Points:
- Power, Flow, Head: Fully aligned with customer requirements.
- Frequency: Clarify if the customer’s power supply is 50Hz or 60Hz. The pump is rated for 60Hz; at 50Hz, performance (flow/head) may drop by ~17%. A VFD or 50Hz motor may be needed if 50Hz is mandatory.
2. Technical Suitability
- Application: Designed for water-based fire suppression systems (compatible with clean water).
-
Construction:
- SS304 Pump Head: Corrosion-resistant for long-term reliability.
- Mechanical Seal: Minimizes leakage risk, critical for fire safety.
- Cast Iron Base/Flange: Durable and cost-effective for standard installations.
-
Performance:
- 2900 RPM: Standard for centrifugal pumps, ensuring stable operation.
- IP55 Motor: Dust and water-resistant, suitable for indoor/outdoor pump rooms.
3. Practical Considerations
-
Installation:
- Ensure self-priming capability or a foot valve if the pump is not gravity-fed.
- Verify suction lift does not exceed manufacturer limits (typically 3–5 meters for centrifugal pumps).
- Redundancy: Recommend a backup pump per NFPA/local fire codes for critical systems.
-
Maintenance:
- Schedule annual mechanical seal inspections.
- Test pump performance quarterly under no-load conditions.
4. Next Steps
-
Frequency Confirmation:
- Contact the customer to verify their power supply frequency (50Hz/60Hz).
-
If 50Hz is required, propose alternatives:
- Option 1: Use a Variable Frequency Drive (VFD) to maintain performance.
- Option 2: Offer a 50Hz-rated motor (e.g., 50CDL20-40-50Hz variant if available).
-
Quote & Documentation:
-
Provide a detailed quotation including:
- Pump price, tax, and shipping costs.
- Warranty terms (typically 12–24 months).
- Lead time for delivery.
- Attach technical datasheets and certification (e.g., CE, UL, or local fire safety marks).
-
Provide a detailed quotation including:
-
Support:
- Offer onsite commissioning (if applicable) or virtual startup guidance.
- Share a maintenance manual and spare parts list upfront.
