DATA:

The characteristics and purposes:

This type submersible pumps (here in after referred to as the electric pump), three parts by water pump, seal and motor, motor for single phase asynchronous motor, water pump for closed impeller, located in the motor below, above QD, Q type impeller is located in the motor. Between the pump and motor adopts double mechanical seal, the fixed check the seal the "O" type static seal oil resistant rubber sealing ring. This series of pumps due to the small volume, light weight, especially suitable for the rural downhole pumping water, farmland irrigation, landscape irrigation and family life, also can be used to eliminate industrial water, construction drainage and farming irrigation and drainage, etc.

Conditions of use:

Pumps used in the following conditions should be continuously to work properly: 
1. For water pumps suitable medium, medium temperature shall not exceed + 40°C
2. The medium PH value between 6.5 ~ 8.5 
3. The volume of medium containing solid impurity is less than 0.1%, the size is not more than 0.2 mm 
4. The power frequency 50 hz, voltage for single-phase 220 v, 380 v, three-phase voltage fluctuation range for rating of 0.9 to 1.1 times 
5. Diving depth of no more than 5 m, is not suitable for irrigation and drainage of sewage and chemicals.
