Bellows backup chamber |
摘要 |
The pump (10) prevents fluid leaks when a bellows (12) ruptures in a pump incorporating a flexible bellows (12) as a primary seal and prevents fluid from leaking out of a pump (10) or the pump (10) ingesting air in the event of a bellows rupture. This is done by adding an additional seal (22) after the bellows and a large volume backup chamber 24. |
