Because the medium viscosity directly affects the choice of high viscosity pump speed.

因为介质粘度的高低直接影响到选择高粘度泵的转速。

So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity.

所以选择不锈钢材质的高粘度泵是一定要注明具体的使用温度，及介质的润滑性。

High viscosity pump can transport high viscosity, high concentration without solid particles or small soft particles lubricity medium;

高粘度泵可以输送高粘度、高浓度无固体颗粒或细小软颗粒的润滑性介质；

youdao

Sweet light crude oil yields the most gallons of gasoline per barrel of oil and since it has low viscosity and low density, it is comparatively inexpensive to pump, transport, and refine.
