# Industrial Specification: Precision Calibration Pump

## 1. Technical Definition
A high-precision fluid delivery component within an electromagnetic flow meter calibrator that generates controlled, repeatable flow rates for calibration purposes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 mL/min at 0.5-6.0 bar differential pressure**. Failure boundary: **Cylinder displacement accuracy degradation beyond ±0.05% of setpoint or leakage exceeding 0.01 mL/min at 6.0 bar**, Mechanism: **Wear-induced clearance expansion between ceramic piston and sapphire cylinder exceeding 2 μm tolerance, causing laminar flow disruption and pressure-dependent volumetric inefficiency**.

### 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.
