# Industrial Specification: Precision Metering Pump Assembly

## 1. Technical Definition
A precision fluid handling component designed to accurately measure and dispense specific volumes of liquid ingredients within an automated beverage blending system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-15.0 bar at 20°C with 0.5% volumetric accuracy**. Failure boundary: **18.7 bar differential pressure causing diaphragm rupture or 85°C fluid temperature causing seal degradation**, Mechanism: **Diaphragm fatigue failure due to cyclic stress exceeding 250 MPa yield strength of PTFE composite material, or thermal expansion mismatch between 316L stainless steel housing and EPDM seals**.

### 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 |
