Product Features

Electrical Machinery

Model115VAC50/60HZ, which is fully enclosed permanent magnet DC motor with natural cooling mode;

Power LineIt is able to be matched 1 meter or random lengths for the three-core power cord 18AWG with length 350mm. Pls see the first diagram.


Working System:

According to different working conditions, S1 work continuously but S3 work intermittently

ConfigurationWhen the shell temperature rises to 64°, the motor will stop working until the shell temperature drops to 35°because the overtemperature protection system in it.

BottomPls see the second diagram and the motor can be selected with or without the base.


Pls see the third diagram. Three-chamber diaphragm pump with self-priming function and the head can choose different joints according to different plug requirements.

Typical ApplicationIt is used for conveying or pressurizing drinking water or other liquids.
