Suwa çümdüriji nasoslar sökmek we abatlamak üçin guýudan bir ýyl işläninden soň, ýa-da bir ýyldan az işlemeli, ýöne iki ýyl çümmek wagty çykarylýar we könelen bölekler çalşylýar.

In order to ensure long-term use of your submersible pump, we strongly recommend that you drain the water in all motor cavities especially in winter to prevent the motor from freezing; at the same time, roll up the cable and tie it well. Store the equipment in a room without corrosive substances and gases, with the temperature below 40 °C. In addition, if you do not use the submersible pump for a long time, be sure to pay attention to rust prevention measures. These simple steps will help you maintain the performance of the equipment and extend its service life.
