1. This pump adopts inner air cooling design, enables heat dispersion performance of the motor to be more superior, therby extends service life of motor.
2. The motor is equipped with thermal protector inside, which ensures motor not to be damaged.
3. Use manual press type pneumatic plant to coutrol pump switch, which effeetively prevents electric leakage caused by water entering switch or high humidity of air, 4. It has strong safety performance. Pump body adopts acid and alkali proof, corrosion proof material, water utilization is more sanitary.
5. Motor shaft is isolated from liquid thoroughly, which prevents rust from influencing seal performance,
6. The greatest merit is that water is absoloutely free of electricity even the motor leaks electricity, thereby it ensures safer operation.
