• Device efficiency improvement

Linear internal flow channel with uniform flow velocity and smooth flow pattern reduces pressure loss and improves device efficiency.

• Good anti-cavitation performance

The blades are rigidly connected to the impeller hub and rotor core as a whole, rotating together with the rotor core to eliminate gaps and improve the anti-cavitation performance of the blades.

• Compact structure reduces civil engineering investment

Installing the pump rotor as a whole in the inner cavity of the motor rotor saves the length of the pump rotor, while also reducing the weight of the pump and the difficulty of on-site installation, which can reduce civil engineering investment by 20% -30%.

• Can achieve remote monitoring

The comprehensive protection system for electric pumps requires completeness, including bearings, windings, and water leakage. It can achieve insulation monitoring and automatic data collection. Equipped with a comprehensive electric pump protector with RS485 interface, it can achieve remote monitoring.

• Wet stator structure, no need for sealing

The stator coil of the motor is a specialized water-resistant winding wire manufactured using multi-layer co-melting and co-extrusion winding wire technology patents, which eliminates the need to worry about insulation safety issues caused by water immersion and also saves the cost of sealing components.

• Adequate cooling and high reliability

The motor is completely immersed in water, providing an excellent heat dissipation effect.

Widely applicable to mechanical and electrical drainage and irrigation, flood control and drainage, or combined with high flow and low head conditions, such as flood control and drainage, river diversion and drainage, and agricultural drainage and irrigation projects.
