還有一種食品級橡膠軟管泵，它的內襯的橡膠層需要達到了食品衛(wèi)生的要求，同時也需要符合EHEDG或者其他衛(wèi)生級的要求。還有三元乙丙橡膠軟管泵，這種一般適用于絕大多數腐蝕性的化學物質和無機物，內襯橡膠層由三元乙丙橡膠構成，外層也是完整的三元乙丙橡膠。這樣的軟管具備很強的抗化學腐蝕的特性。以及CSM軟管泵，它適用于特別腐蝕性的化學介質，如：強氧化溶劑。軟管的內層是CSM，外層是天然橡膠。運行溫度達到85℃/185°F。

There is also a food-grade rubber hose pump. Its rubber layer must meet food hygiene requirements, and it must also meet EHEDG or other sanitary requirements. There is also a EPDM hose pump, which is generally suitable for most corrosive chemicals and inorganic materials. The inner rubber layer is composed of EPDM rubber, and the outer layer is also a complete EPDM rubber. Such hoses have strong chemical resistance. And CSM hose pump, it is suitable for particularly corrosive chemical media, such as: strong oxidizing solvents. The inner layer of the hose is CSM and the outer layer is natural rubber. Operating temperature reaches 85 ° C / 185 ° F.
