# Industrial Specification: Pump Assembly

## 1. Technical Definition
A mechanical assembly that pressurizes and circulates water through a sprinkler system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-10.0 bar (25-100 m H₂O head)**. Failure boundary: **15.3 bar (156 m H₂O) at 20°C water temperature**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold (2.34 kPa at 20°C) causing impeller material fatigue (NPSHr &gt; NPSHa)**.

### 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 |
| :--- | :--- | :--- | :--- |
| Dry running for &gt;120 seconds | 8 | Seal overheating to 180°C causing elastomer degradation | Integrate capacitive proximity sensor with 5 mm detection range for liquid presence |
| Particulate contamination &gt;50 μm concentration | 8 | Abrasive wear on impeller vanes reducing efficiency by 40% | Install 25 μm stainless steel mesh filter with differential pressure monitoring at 0.3 bar |
