# Industrial Specification: High-Pressure Fish Pump Impeller

## 1. Technical Definition
Centrifugal impeller for transferring fish and seafood products through processing lines.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar (50-600 kPa) discharge pressure, 0.1-2.0 m³/min flow rate**. Failure boundary: **Cavitation occurs at NPSHa &lt; 3.2 m, structural failure at &gt;8.0 bar (800 kPa) discharge pressure or &gt;1800 RPM**, Mechanism: **Cavitation-induced pitting from vapor bubble collapse at NPSHa &lt; NPSHr + 0.6 m safety margin, causing material erosion at 150-300 MPa localized pressure spikes**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Solid particle ingestion &gt;2 mm diameter at &gt;15% concentration by volume | 8 | Leading edge erosion reducing hydraulic efficiency by &gt;40% within 200 operating hours | Install 1.5 mm mesh stainless steel strainer upstream with differential pressure monitoring at 0.3 bar trigger |
| Bearing lubrication failure from washdown water ingress exceeding IP69K rating for &gt;30 minutes | 8 | Bearing seizure causing shaft deflection &gt;0.15 mm, resulting in impeller-contact housing wear | Double mechanical seal design with food-grade grease purge system maintaining 0.2 bar positive pressure |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What makes this impeller suitable for fish processing applications?
**A**: This impeller is constructed from 316L stainless steel and food-grade polypropylene, which are corrosion-resistant and FDA-compliant, ensuring safe contact with fish and seafood products while withstanding harsh processing environments.

### Q: How does the impeller handle different fish product consistencies?
**A**: The centrifugal design with radial vanes efficiently transfers various consistencies, from whole fish to processed seafood, maintaining product integrity with minimal damage, supported by adjustable flow rates and RPM settings.

### Q: What maintenance is required for the wear ring and balance weights?
**A**: Regular inspection of the wear ring and balance weights is recommended to ensure optimal performance and longevity; these components are designed for easy replacement to minimize downtime in processing operations.

## 6. Manufacturing Compliance
- ISO 2858:2012 (END-SUCTION CENTRIFUGAL PUMPS - DESIGNATION, NOMINAL DUTY POINT AND DIMENSIONS)
