# Industrial Specification: Fluid Path Assembly

## 1. Technical Definition
The integrated assembly that defines and contains the fluid flow path within a peristaltic or piston filling pump.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-15 MPa (1-150 bar)**. Failure boundary: **18.5 MPa (185 bar) for burst failure, 12 MPa (120 bar) for permanent deformation**, Mechanism: **Yield strength exceedance of 316L stainless steel (205 MPa) at wall thickness of 2.5 mm under internal pressure, calculated via Lamé equations for thick-walled cylinders**.

### 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 25 μm in fluid stream | 8 | Seal abrasion leading to 0.5 mm³/s leakage rate | Install 10 μm absolute filtration with differential pressure monitoring at 0.3 bar threshold |
| Thermal cycling between 5°C and 85°C at 2 cycles/hour | 8 | Differential thermal expansion causing 0.15 mm misalignment in O-ring grooves | Implement controlled ramp rates of 1°C/minute and PEEK thermal expansion compensators |

- **Caution**: 

### Q: What materials are recommended for sanitary fluid path assemblies in food processing?
**A**: For sanitary food processing applications, we recommend 316L stainless steel for metal components and food-grade plastics like PTFE or PEEK for wetted parts, which offer excellent chemical resistance and meet FDA compliance requirements.

### Q: How does the fluid path assembly differ between peristaltic and piston filling pumps?
**A**: Peristaltic pump assemblies typically feature a flexible tubing section that gets compressed, while piston pump assemblies include valve mechanisms to control fluid intake and discharge. Both share common components like inlet manifolds, pumping chambers, and outlet nozzles.

### Q: What maintenance considerations are important for fluid path assemblies?
**A**: Regular inspection of seals and gaskets for wear, cleaning of wetted surfaces to prevent contamination, and monitoring tubing sections for fatigue in peristaltic systems are crucial. Proper material selection for your specific fluid chemistry will maximize assembly lifespan.

## 6. Manufacturing Compliance
