1. The medium used should be similar to water, with a kinematic viscosity <150mm2/s, without hard particles, and without corrosive properties;
2. The environment altitude of the multi-stage centrifugal pump
is less than 1000 meters, if it exceeds, it should be mentioned in the order, so that the factory can provide you with more reliable products;
3. The operating temperature of the medium is -15℃～120℃;
4. The maximum system working pressure≤2.5MPa;
5. The ambient temperature should be lower than 40℃, and the relative humidity should be lower than 95%.
