The choice of distribution principle determines reliability, maintainability and costs. Here is the compact comparison – plus information on design.
Introduction
- Mission: short lines, moderate score
- Advantages: simple, inexpensive, easy to dose
- Limitations: Pay attention to cable lengths/temperature windows
Dual line
- Mission: long lines, many points, harsh environment (often grease)
- Advantages: robust, insensitive to temperature, large networks
- Limitations: higher system effort
Progressive
- Mission: clearly defined quantities per cycle, good monitoring
- Advantages: clear error detection (stroke monitoring)
- Limitations: fixed order, does not tolerate blockages
Selection criteria
- Number of lubrication points & line lengths
- Medium: Oil (viscosity) or grease (NLGI 00-2)
- Temperature/environment, desired monitoring depth
