# Industrial Specification: Metering Valve/Pump

## 1. Technical Definition
A precision fluid control component that accurately measures and dispenses specific volumes of compounds within a compound applicator system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 mL/min at 2.0-8.0 bar differential pressure**. Failure boundary: **Cylinder bore wear exceeding 5.0 μm radial clearance or plunger seal leakage exceeding 0.1% of nominal flow rate**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold (0.023 bar absolute at 20°C) or progressive wear from abrasive particles &gt;15 μm diameter exceeding Mohs hardness 5.0**.

### 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 |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Plunger seal scoring leading to volumetric accuracy degradation beyond ±0.5% specification | Installation of 3.0 μm absolute rated duplex filtration with differential pressure monitoring at 0.7 bar warning threshold |
| Thermal cycling between -10°C and 80°C at &gt;2 cycles/hour | 8 | Differential thermal expansion mismatch (CTE 23×10⁻⁶/K for 316SS vs 110×10⁻⁶/K for PTFE) causing seal extrusion failure | Thermal stabilization jacket maintaining fluid temperature within ±2°C of 25°C setpoint |

- **Caution**: 
- **Caution**: 

### Q: What materials are used in this metering valve/pump for corrosion resistance?
**A**: This metering valve/pump utilizes stainless steel for structural components, PTFE (Polytetrafluoroethylene) for seals and gaskets, and ceramic for wear-resistant surfaces, ensuring excellent corrosion resistance and longevity in harsh industrial environments.

### Q: How does the piston/cylinder assembly ensure accurate volume measurement?
**A**: The precision-engineered piston/cylinder assembly provides consistent displacement with minimal tolerance variation, enabling accurate measurement and dispensing of specific fluid volumes within compound applicator systems, typically achieving accuracy within ±1% of target volume.

### Q: What maintenance is required for the drive mechanism and control valve components?
**A**: Regular inspection of the drive mechanism for wear and lubrication, along with periodic checking of control valve seals and gaskets for degradation, is recommended. PTFE and ceramic materials reduce maintenance frequency, but following manufacturer's service intervals ensures optimal performance.
