How can a self priming pump meet the standards?


Standard self priming pumps are being used in an increasing number of operating conditions, and only those that meet the following conditions are truly self priming pumps:
1. The self priming pump is a vertical self priming pump, with the motor and self priming pump coaxial.
2. All motors must have dedicated motors, and the entire rotor of the self priming pump should be supported by the bearings of the motor.
3. The original model of the automatic control self priming pump was WFB, but later on, other WFZB, WZB, and YWB were all modified based on the model of the old automatic control self priming pump.
4. The flow rate and head of the self priming pump should be within a range value. When the flow rate is high, the head of the self priming pump is small. When the head is high, the flow rate of the self priming pump is small.
5. The performance of the self priming pump can be adjusted using a valve, and the flow and head of the self priming pump can be controlled by the switch size of the valve.
6. When used at temperatures below 40 degrees Celsius, it does not affect the performance of the self priming pump.
7. The self-control self priming pump should have reliable rust prevention measures, the surface should be polished smooth, the welding should have no cracks, and collision should not scratch.
8. It is necessary to have an electromagnetic control valve, and no self priming pump is said to have no air control valve.
