WQ series submersible pump
- Adopting CFD technology and being more efficiency
- Taking unique mechanical seal pattern and bearing structure for more reliable.
- Being compact structure with small volume and light weight, and easier for daily maintenance.
- Being submersible working, so it is low noise.
WQ series submersible sewage pumps are mainly allocated to projects of municipal administration ,buildings,industral emission of sewage,hotels,hospital,civil air defense,mining area .etc., which are used to emit sewage with solid as well as fiber with long figure waste water rain and water for city life
- the tempreture of medium should not exceed 40℃.and the density can’t be larger than 1200Kg/m3 with PH value between 5 and 9.
- the bottom line of operation should follow the drawing of installation, “with motor cooling system or without motor cooling system”.
- specified voltage: 380V,specified frequency:50Hz. Under the circumstance of specified voltage and specified frequency does the electrical machinery run good.
- the largest diameter of solid passing through pumps should not fail to half the diameter of pump exit or even less.
