# Industrial Specification: Sanitary Centrifugal Pump

## 1. Technical Definition
A hygienic pump designed for transferring liquids in sanitary processing applications using centrifugal force.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-10 bar differential pressure, 0.1-100 m³/h flow rate, -10°C to 140°C fluid temperature**. Failure boundary: **Cavitation occurs at NPSHa &lt; NPSHr + 0.5 m, mechanical seal fails at shaft deflection &gt; 0.05 mm, impeller fatigue at &gt;10⁷ cycles at 110% rated speed**, Mechanism: **Cavitation from vapor pressure drop below fluid vapor pressure at 2.34 kPa at 20°C, bearing seizure from lubricant breakdown at &gt;80°C, impeller cracking from cyclic stress exceeding 200 MPa yield strength**.

### 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.
