Automatic lightweight submersible dewatering pump

• Inflation class: F
• Protection class: IP68
• Cable length: 20 m
• Water temperature: up to 40°C
• Max water depth: 25 m

Compared with other lightweight pumps, cast aluminum casings are always stronger than those made from sheet metal. EFE-370TBA series pumps are also suitable for dewatering on construction sites, underground tunnels and mining work.

Intelligent control system:
• Protects against phase inversion, ensuring correct wheel rotation (3 phases only);
• Protects against open phase or wheel lock, thus avoiding accidental damage;
• Automatically stops the pump in case of overload, abnormal voltage with recovery after 5 minutes;
• The pump stops working at high temperature and will restart automatically after cooling to the specified temperature;
• The height of the water level sensor is adjustable for the operation of the contrai pump;
• The pump stops working within 60 seconds when the water level is lower than the water level sensor, which keeps the stop time for 180 seconds, after the 180 seconds, meanwhile the water level is higher than the water level sensor, the pump works again;
• Assessment of pump operation and malfunction history (3 phases only).
