Rotary lobe pumps can run in reverse, making them ideal for systems that require bidirectional flow. Centrifugal pumps can’t run in reverse or may be damaged.
Rotary lobe pumps can run dry with lubricated seals, but water pumps get damaged. Install dry-running protection or choose suitable pumps.
Factors affecting rotary lobe pump flow and pressure include operational issues, low speed, leaks, defects, and wear and tear.
Prevent pump shaft breaks by choosing reliable manufacturers, avoiding excess pressure/speed, solving vibration, and ensuring proper installation.
Proper gear oil level is crucial to prevent overheating. Check for low oil level, incorrect oil, dry pump, or contaminated oil. Regular maintenance is recommended.
