QB series water pump motor belongs to the vortex pump direct-coupledmotor and pump, with simple structure, small size, light weight, higher head. The flow of this pump is relatively small, and it is suitable for conveyingwater whose temperature does not exceed 40°C or physical and chemical properties which are similar to water liquid. The pump applies to domestic wells pumping, car washing, fountains, water supply, garden irrigationand other occasions.
Operating conditions:
The pump can work normally in the following conditions:
1. Medium temperature is no more than 40°C
2. PH should be 6.5-8.5.
3. The volume ratio of sediment concentration in the medium is no more than 0.1%, and the particle size should not exceed 0.2mm.
4. The power frequency is 50Hz, the voltage of single-phase is 220v, the voltage of three-phase is 380v. The voltage fluctuation ranges from 0.9 to1.1 times of the rating.
