Feature:
1.Some of models are adopted flow impeller, which can improve anti-clogging ability effectively;
2.Some of models are adopted total head design theory, which can make pump keep running without overload under normal condition. So that it can prolong the service life of pump.
Service condition:
1.Pumped medium temperature is less than 40℃.
2.PH value should be 4-10.
3.Volume ratio of solid material in Pumped medium should be less than 2%
4.Actual pump lift can not be less than 80% of rated pump lift. Otherwise, thermal protector will stop pump running. What is more, it will break the motor.
