还有一种食品级橡胶软管泵，它的内衬的橡胶层需要达到了食品卫生的要求，同时也需要符合EHEDG或者其他卫生级的要求。还有三元乙丙橡胶软管泵，这种一般适用于绝大多数腐蚀性的化学物质和无机物，内衬橡胶层由三元乙丙橡胶构成，外层也是完整的三元乙丙橡胶。这样的软管具备很强的抗化学腐蚀的特性。以及CSM软管泵，它适用于特别腐蚀性的化学介质，如：强氧化溶剂。软管的内层是CSM，外层是天然橡胶。运行温度达到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.
软管泵的工作原理及应用：软管在泵体内呈U形布置。当旋转体带动挤压轮旋转时，挤压软管受到挤压轮的挤压而发生弹性变形，然后吸入口形成负压吸浆。通过挤压轮的推动，浆液从出料口排出，形成浆液的压力输送。工业软管泵主要应用于建筑、地下工程、矿山、食品、造纸、陶瓷等领域的粘性浆液远距离输送、计量泵送、压力灌浆、喷射等。
Working principle and application of hose pump: The hose is arranged in a U-shape in the pump body. When the rotating body drives the extrusion wheel to rotate, the extrusion hose is elastically deformed by the extrusion wheel, and then the suction port forms a negative pressure suction slurry. By the push of the squeeze wheel, the slurry is discharged from the discharge port, forming a pressure transfer of the slurry. Industrial hose pumps are mainly used for the long-distance transportation of viscous slurry in the fields of construction, underground engineering, mining, food, papermaking, ceramics, metering pumping, pressure grouting, spraying, etc.

1、使用软管泵时调压板请不要拧得太紧，以免“扎死”泵头，一般调到有液体流出即可，以延长其使用寿命。
2、泵头在快速运转中，切勿按动“顺/逆”开关，若要按动，则先将速度调慢后再按动，然后再将速度调至原来速度，即将电压表读数调至原来值。
3、软管泵在使用期间，应随时注意软管是否完好，一般在中速情况下运转为佳，当发现软管使用老化时，应及时更换软管。
4、使用完毕要将泵头清洗干净，若长时间不使用，应取下软管，以延长其使用寿命。
5、软管泵长期不用时，请把软管从泵头中取出，延长其使用寿命。软管是易损物品，使用一段时间后请及时更换。不然会造成漏液，损坏仪器！
6、根据不同介质和不同流量，请选用不同粗细的软管。
