# Industrial Specification: Cooling Water Pump

## 1. Technical Definition
A pump specifically designed to circulate cooling water within industrial cooling systems to remove heat from equipment or processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1.5-10 bar differential pressure, 5-35°C inlet temperature, 0.5-3.0 m/s flow velocity**. Failure boundary: **NPSHr &gt; NPSHa by 0.3 m, bearing temperature &gt; 95°C, shaft deflection &gt; 0.05 mm**, Mechanism: **Cavitation occurs when vapor pressure (2.34 kPa at 20°C) exceeds local pressure, causing vapor bubble collapse with 1000+ bar microjets eroding impeller surfaces**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient NPSHa due to suction lift &gt; 6 m or high fluid temperature &gt; 60°C | 8 | Cavitation erosion on impeller vanes causing 15% efficiency loss within 2000 hours | Installation of booster pump maintaining 2 m NPSH margin, or cooling loop reducing fluid temperature to 35°C |
| Misalignment &gt; 0.1 mm/m between pump and motor shafts during installation | 8 | Bearing fatigue failure at 10⁷ cycles under 500 N radial load, causing catastrophic seizure | Laser alignment during installation achieving &lt;0.05 mm/m tolerance, coupled with flexible coupling absorbing 0.5° angular misalignment |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for cooling water pumps in corrosive environments?
**A**: For corrosive environments, stainless steel or bronze construction is recommended as they offer superior resistance to rust and chemical degradation compared to cast iron.

### Q: How often should cooling water pump bearings be inspected?
**A**: Bearings should be inspected every 3-6 months depending on operating conditions. Regular maintenance prevents overheating and extends pump life in industrial machinery systems.

### Q: Can this pump handle high-temperature cooling water applications?
**A**: Yes, with proper material selection (especially stainless steel components) and seal specifications, these pumps are designed to circulate cooling water in high-temperature industrial processes.

## 6. Manufacturing Compliance
- ISO 5199:2016 (TECHNICAL SPECIFICATIONS FOR CENTRIFUGAL PUMPS)
- EN 809:1998+A1:2009 (PUMPS AND PUMP UNITS FOR LIQUIDS - COMMON SAFETY REQUIREMENTS)
