Questions and answers
Dear Sir, what are the possible reasons for frequent damage to the manometer. Warm greetings
The possible reasons for frequent damage to the Pratissoli SH Series manometer include:
- Excessive pressure due to malfunctioning pressure regulating valves.
- Pipe vibrations or knockings caused by air suction or irregular drive transmission motion.
- Pump operation at higher than rated revolutions per minute (r.p.m.).
- Incorrect alignment or excessive inclination of the pump during operation.
- Clearance in the drive system leading to irregular motion.
- Water in oil or worn-out components causing internal stress.
These conditions can cause pressure surges or irregular forces that may damage the manometer.
