50---Discharge Diameter(mm)
WQ---Submersible Sewage Pump
15---Capacity(m3/h)
8---Head(m)
0.75---Power of fitted motor
Condition of use
1.The medium temperature should not be over 40 C, the density 1200Kg/m , and the PH value within 5-9.
2.During running, the pump must not be lower than the lowest liquid level, see " lowest liquid level" in the drawing of installation dimensions(covering theautomaticcooling system), means lowest liquid level without no automatic cooling system.
3.Rated voltage 380V, rated frequency 50Hz. The motor can run successfully only under the condition the deviations of both rated voltage and frequency are not over 5%.
4.The maximum diameter of the solid grain going through the pump has notto belarger than 50% of that of the pump outlet.
