# Industrial Specification: Drain Pump

## 1. Technical Definition
A pump designed to remove liquids from systems or equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar differential pressure, 5-60°C fluid temperature, 0.1-10.0 m³/h flow rate**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, bearing failure at &gt;120°C housing temperature, seal failure at &gt;80°C fluid temperature**, Mechanism: **Cavitation-induced pitting from vapor bubble collapse at NPSH margin &lt;0.5 m, bearing lubricant thermal breakdown at Arrhenius rate doubling per 10°C above 100°C, elastomer seal hardening via polymer chain scission at &gt;80°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.
