還(huan)(huan)有(you)一種食品級(ji)橡膠(jiao)(jiao)軟(ruan)管(guan)泵，它的(de)內(nei)襯(chen)的(de)橡膠(jiao)(jiao)層(ceng)需要達到了食品衛生的(de)要求，同時也需要符合EHEDG或(huo)者(zhe)其他(ta)衛生級(ji)的(de)要求。還(huan)(huan)有(you)三元乙丙(bing)橡膠(jiao)(jiao)軟(ruan)管(guan)泵，這(zhe)種一般(ban)適(shi)用于絕大多數腐蝕(shi)性(xing)的(de)化學物質和無機物，內(nei)襯(chen)橡膠(jiao)(jiao)層(ceng)由三元乙丙(bing)橡膠(jiao)(jiao)構成，外(wai)層(ceng)也是完(wan)整(zheng)的(de)三元乙丙(bing)橡膠(jiao)(jiao)。這(zhe)樣的(de)軟(ruan)管(guan)具備很強的(de)抗化學腐蝕(shi)的(de)特(te)性(xing)。以及CSM軟(ruan)管(guan)泵，它適(shi)用于特(te)別(bie)腐蝕(shi)性(xing)的(de)化學介質，如(ru)：強氧化溶劑(ji)。軟(ruan)管(guan)的(de)內(nei)層(ceng)是CSM，外(wai)層(ceng)是天然(ran)橡膠(jiao)(jiao)。運(yun)行溫度(du)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.
