Seeking help with issues regarding tetrafluoro self-priming pumps
Thread Content
Dear teachers, will wear and tear of the PTFE sealing rings on the impeller and pump casing cause the pump to fail to generate pressure?
This question is not easy to answer. What does the wear look like? No pressure means there is no pressure at all, or is it that the pressure is insufficient?
Backflow, to a certain extent, will definitely affect the outlet pressure
No water is coming out because the self-priming mechanism can no longer draw up the liquid.
Leaks in any part of the entire fluid flow path can result in a failure to generate pressure, as self-priming pumps require a vacuum to function; without such a vacuum, water cannot be drawn up
