工作条件
Working conditions
SLB型泵适用温度≤90℃。热水型≤120℃。系统最高工作压力2.5MPa；即泵出口压力=泵入口压力+扬程≤2.5 Mpa，根据泵承受的最大压力，泵体和泵盖材质采用灰口铸铁（1.6Mpa），球墨铸铁（2.0 Mpa），铸钢（2.5 Mpa，包括不锈钢），在订货时敬请注明泵的承压情况或材质。
The suitable temperature of SLB pump is less than 90 C. Hot water type < 120 C. The maximum working pressure of the system is 2.5 MPa, that is, the pump outlet pressure = the pump inlet pressure + head < 2.5 Mpa. According to the maximum pressure, the pump body and cover are made of gray cast iron (1.6 Mpa), ductile iron (2.0 Mpa), cast steel (2.5 Mpa, including stainless steel). Please specify the pressure bearing condition or material of the pump when ordering.
