It is known that the use of traditional diaphragm piston pumps lays down certain limits for handling mechanically or chemically aggressive and / or abrasive media 众所周知,传统的隔膜活塞泵在处理具有机械或化学侵蚀性的或磨蚀性的介质时,会受到一定的限制。
For example , strongly crystallising fluids or abrasive liquids which settle in the lower pump area between diaphragm and diaphragm retainer ring lead to a premature diaphragm rupture 例如,具有强结晶倾向的或磨蚀性的流体会在隔膜和隔膜固定圈间产生沉淀,导致隔膜过早地损坏。
