# Industrial Specification: Supply Pump

## 1. Technical Definition
A mechanical device that moves water through a water supply system by creating pressure differentials.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-8.0 bar (36-116 psi)**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, bearing failure at &gt;120°C lubricant temperature, seal failure at &gt;15 bar differential pressure**, Mechanism: **Cavitation from vapor pressure drop below 0.023 bar at 20°C water, bearing thermal expansion exceeding 0.15 mm radial clearance, elastomer seal degradation above 150°C**.

### 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 |
| :--- | :--- | :--- | :--- |
| Impeller imbalance exceeding ISO 1940 G6.3 grade (0.4 mm/s vibration velocity) | 8 | Bearing fatigue failure at &gt;10^7 cycles with 400 MPa contact stress | Dynamic balancing to ISO 1940 G2.5 grade (0.16 mm/s) with 0.01 mm impeller tolerance |
| Dry running for &gt;30 seconds with 0.05 m³/min flow deficit | 8 | Mechanical seal overheating to &gt;250°C with 5 μm/min wear rate | Flow switch interlock at &lt;0.1 m³/min with 2-second response time and PTFE secondary seal |
