# Industrial Specification: Precision Metering Pump

## 1. Technical Definition
A pump designed to deliver precise, repeatable volumes of liquid ingredients in automated dispensing systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 bar at 0.1-100 mL/min flow rate**. Failure boundary: **Cavitation occurs at NPSHa &lt; 0.5 m, diaphragm rupture at &gt;150 bar, stepper motor stall at &gt;1.5 N·m torque**, Mechanism: **Cavitation from vapor pressure differential (ΔP &gt; 2.3 kPa at 20°C), diaphragm fatigue from cyclic stress exceeding 35 MPa yield strength, stepper motor desynchronization from &gt;5% load inertia mismatch**.

### 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 |
