還有一種食品級(jí)橡膠軟管泵，它的內(nèi)襯的橡膠層需要達(dá)到了食品衛(wèi)生的要求，同時(shí)也需要符合EHEDG或者其他衛(wèi)生級(jí)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(shù)腐蝕性的化學(xué)物質(zhì)和無(wú)機(jī)物，內(nèi)襯橡膠層由三元乙丙橡膠構(gòu)成，外層也是完整的三元乙丙橡膠。這樣的軟管具備很強(qiáng)的抗化學(xué)腐蝕的特性。以及CSM軟管泵，它適用于特別腐蝕性的化學(xué)介質(zhì)，如：強(qiáng)氧化溶劑。軟管的內(nèi)層是CSM，外層是天然橡膠。運(yùn)行溫度達(dá)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.
