✅Solutions to Avoid Dry Burning dry running.(Preventing stator dry-running wear is key to extending progressive cavity pump service life.)
The first part to be damaged was screw pump stator.No matter in what situation,progressive cavity pump for sludge transfer pump,sewage pump(sewage/wastewater treatment),oil and gas transfer,Food transfer,any more
1. Install protection devices
Equip with low-flow sensors, suction pressure switches, dry-run relays for auto-shutdown on anomalies.
2. Optimize operation procedures
Ensure full priming before startup; ban long idle running; assign regular parameter checks.
3. Upgrade pipeline design
Add recirculation line for minimum lubrication flow; install inlet check valve to prevent backflow.
4. Strengthen maintenance
Calibrate sensors/alarm systems regularly; inspect inlet filters frequently to avoid blockage.
