一、工作條件 Condition

1、泵系統最高壓力為1.6MPa.即泵吸入口壓力+泵揚程<1.6MPa.(訂貨時請注明系統工作壓力、泵系統工作壓力大于1.6MPa時，應在訂貨時另

行提出。以便在制造時泵的過流部分和聯接部分采用鑄鐵材料。)

2、適用介質:固體不溶物體積含量不超過單位體積的0.1%，粒度不大于0.2mm。(介質如帶有細小顆粒須采用耐磨式機械密封，請在訂貨時說

明。)

3、周圍環境溫度不超過40℃，相對濕度不超過95%，海拔高度不超過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.
