一、工作条件 Condition

1、泵系统最高压力为1.6MPa.即泵吸入口压力+泵扬程<1.6MPa.(订货时请注明系统工作压力、泵系统工作压力大于1.6MPa时，应在订货时另

行提出。以便在制造时泵的过流部分和联接部分采用铸铁材料。)

2、适用介质:固体不溶物体积含量不超过单位体积的0.1%，粒度不大于0.2mm。(介质如带有细小颗粒须采用耐磨式机械密封，请在订货时说

明。)

3、周围环境温度不超过40℃，相对湿度不超过95%，海拔高度不超过1000m。

1.The pump system maximum pressure is 1.6lMPa,that is to say the pump suction pressure + pump head < 1.6MPa.Please specify the sytem

working pressure when) ordering,if pump system working pressure is greater than 1.6MPa.,should be separately put fonward when ordering,therefore

we wil use of steel materials to manufacture the over-current and connected parts of the pump.)

2.Medium:insoluble solids volume contents of no more than the volume per unit's 0.19%, paricle size less than 0.2mm.lif the medium contenis

of small particles, the wear-resistant mechanical seals is used.So please note it when ordering.)

3.The ambient temerature does not exceed 40'c, relative humidity is no more than 95%.altitude does not exceed 1000m.
