# Industrial Specification: Transfer Pump

## 1. Technical Definition
A pump component used to transfer fluids between stages or sections within a larger inter-stage transfer system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar differential pressure, 5-85°C fluid temperature, 0.1-15 m³/h flow rate**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, mechanical seal fails at shaft deflection &gt; 0.05 mm, bearing failure at vibration velocity &gt; 4.5 mm/s RMS**, Mechanism: **Cavitation-induced pitting from vapor bubble collapse at local pressure &lt; fluid vapor pressure, mechanical fatigue from cyclic stress exceeding 250 MPa yield strength, thermal degradation of elastomers above 120°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.
