# Industrial Specification: Dosing Pump

## 1. Technical Definition
A precision pump designed to inject or transfer controlled volumes of liquids, chemicals, or additives into a process stream or system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-40 bar**. Failure boundary: **45 bar (diaphragm rupture pressure)**, Mechanism: **Diaphragm material yield strength exceeded at 45 MPa stress, causing plastic deformation and rupture**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cavitation at NPSH &lt; 2.3 m | 8 | Diaphragm pitting and fatigue cracking | Installation of booster pump maintaining NPSH &gt; 3.0 m |
| Chemical incompatibility with PTFE diaphragm at pH &lt; 2 or pH &gt; 12 | 8 | Diaphragm chemical degradation and permeability failure | Material substitution with FFKM perfluoroelastomer diaphragm |

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

### Q: What materials are used in your dosing pumps for chemical resistance?
**A**: Our dosing pumps feature materials like 316L stainless steel, PTFE, ceramic, and PVDF to ensure excellent chemical resistance and durability in harsh industrial environments.

### Q: How does the control unit ensure precise dosing accuracy?
**A**: The control unit uses advanced microprocessor technology to regulate the drive mechanism and valves, maintaining consistent flow rates and volumes with minimal deviation for reliable process control.

### Q: What maintenance is required for the pump head components?
**A**: Regular inspection of the pump head, including seals and valves, is recommended. Materials like PTFE and ceramic are chosen for low maintenance, but periodic cleaning and part replacement ensure optimal performance.
