The type of the pump impeller and pump and centrifugal pump with a volume effect of particles suspended in mid-stream leaf out of date, do not hit any part of the pump, it is good non-destructive.
该型叶轮的泵兼具有容积泵和离心泵的作用，悬浮性颗粒在叶片中流过时，不撞击泵内任何部位，故无损性好。

Standard pump designs are centrifugaltype rated for the temperature range. For extreme temperatures, magnetic or seal-less pumps are employed.
标准泵为离心式，或根据温度设定功率。极端温度下可使用磁力泵和无封焊水泵。
