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生的要求，同時也需要符合EHEDG或者其他衛生級的要求。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.

產品應用及主要特點：該泵具有四種流量和四種壓力，流量和壓力變化范圍大，可適用不同孔徑的鉆進和回拖同時也可用作回轉鉆進等巖心鉆探、化工、礦井排污以及軟基注漿等施工。<br />
主要特點<br />

4、易損件壽命長，可靠性高。<br />！

首先我們先介紹一下軟管泵，軟管泵又稱蠕動泵。為了泵體污染流體或流體污染泵體的危險性，整個泵的裝置中只有軟管與介質接觸。在一般場合下，軟管泵使用的都是天然橡膠的軟管。內層和外層都是完整光滑的天然橡膠，其目的是很強防磨損。適用于腐蝕性不高但磨損性很大的如泥漿以及無機物等等介質。而且一般適用于脂肪、油類或油脂的介質，以及有機化學物質。內層是橡膠，而外層是天然橡膠或者是復合橡膠。

First of all, lets introduce the hose pump, which is also called peristaltic pump. In order to eliminate the danger of the pump body contaminating the fluid or the fluid contaminating the pump body, only the hose in contact with the medium in the entire pump device. In general, hose pumps use natural rubber hoses. The inner and outer layers are completely smooth natural rubber, the purpose of which is to prevent abrasion. It is suitable for mediums that are not corrosive but very abrasive, such as mud and inorganic substances. And generally suitable for fats, oils or oils, and organic chemicals. The inner layer is rubber, while the outer layer is natural rubber or composite rubber.
