Description ：
The body of motor and pump is made of rigid cast iron for long-lasting durability.
Greatly increased maximum submersion depth due to mechanical seal resistant to high pressure.
Semi-open impeller made of high chrome alloy match with wear plate (ductile iron) achieves superior durability. Effective motor cooling due to discharge channel cast as part of the motor housing. Space economically by a top outlet. The pump can operate automatically with built-in intelligent control system, thus achieve low total energy costs.
Main advantages ：
Protcet against reverse phase,ensuring correct impeller rotation;
Protect against open phase or impeller jam,thus prevent accidental damage;
Automatically stop the pump in event of overload,abnormal voltage and recovery 5min later;
The pump stops working at high temperature,and will automatically restart after cooling to the specified temperature;
The water sensor's height is adjustable to control pump operation and stop;
The pump stops working within 60s when water level is below the probe,When the water level rises to contact the electric probe, pump starts operating agai ;
Rapid assessment about the pump operation and malfunction history.
