# Industrial Specification: Molten Metal Pump

## 1. Technical Definition
A specialized pump designed to transfer molten metal within industrial metal processing systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar differential pressure, 700-1200°C temperature, 0.1-1.0 m/s flow velocity**. Failure boundary: **Thermal fatigue cracking at 1200+ thermal cycles (ΔT&gt;300°C), refractory erosion &gt;15mm thickness loss, impeller cavitation at NPSH&lt;2.5m**, Mechanism: **Thermal stress exceeding refractory material yield strength (σ_y&gt;50MPa at 1000°C), liquid metal corrosion of ceramic components, vapor pressure collapse at pump suction**.

### 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.
