Overview
The Positive Displacement Injector (PDI) System is a precision centralized lubrication system that delivers accurate and uniform quantities of lubricant to each lubrication point through dedicated injectors.
Key Features
- Precise metering: Delivers a fixed quantity of lubricant to each point with minimal deviation.
- Pressure-activated operation: Injection only occurs when preset pressure is reached, ensuring safety.
- System monitoring: Pressure sensors or switches monitor real-time system health.
- Modular design: Injectors are easily replaceable without disrupting the whole system.
- Flexible expansion: Supports multi-point lubrication with ease.
Advantages
| Benefit | Description |
