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.
