Down-suction submersible electric pump, designed for vertical installation with the motor positioned above and the pump below. It features a down-suction immersed impeller directly mounted on the motor shaft extension, creating an integrated motor-pump unit that boasts a compact design, minimal footprint, and reduced space requirements. This model can be manufactured as a multi-stage pump, achieving head heights exceeding 150 meters. The pump operates smoothly, is easy to operate, simple to install, convenient for maintenance, and benefits from a high degree of standardization.
Technological Advantages
Efficient cooling structure design: The motor features an integrated internal design, allowing liquid to flow rapidly through the motor stator housing for superior cooling performance.
Reliable cable outlet design: Features a unique cable exit and sealing mechanism that enhances sealing performance, preventing cables from being damaged by high-pressure water impacts—and ultimately extending their service life.
Motor internal pressure-reducing design: Due to the slight leakage characteristic of the mechanical seal, the internal motor pressure gradually drops to match the pump outlet pressure, which can damage the winding wires and lead to failure of the seals at the motor’s cable terminations and cables—potentially resulting in motor damage. Therefore, this product features a unique pressure-reducing design that ensures the motor operates at a low-pressure state inside.
Application
Widely used in metallurgy, municipal engineering, mining, chemical industries, papermaking, agricultural irrigation, hospitals, thermal power plants, hydroelectric stations, and other facilities—particularly well-suited for applications like drainage in underwater tunnels, where precise control of the minimum water level is critical (typically requiring a minimum depth greater than 1 meter).
