Implementation Standards For Deep-Well Pumps

Deep-well pumps comply with national standard GB/T2816-2002.
Three-phase submersible asynchronous motors for deep-well pumps comply with standard GB/T2818-2002.

This type of vertical-shaft centrifugal deep-well pump consists of three main components: the working section (equipped with a strainer), the riser pipe section (containing the drive shaft), and the drive unit (housing the motor). The working section and riser pipe are submerged in the well, while the drive unit is located at the wellhead. As the impeller rotates, both pressure head and flow velocity increase; the water flows through the channels of the diffuser casing to the next impeller. This process repeats through successive impellers and diffusers, progressively increasing the pressure head. The pump offers a delivery head ranging from 26 to 138 meters. Unconstrained by liquid level or concentration limits, these pumps are widely used in mining, the petroleum industry, and other industrial sectors.

These pumps are essential equipment for extracting water from deep wells to supply municipalities, industrial and mining enterprises, and agricultural irrigation systems. Key advantages include high single-stage lift, advanced structural design and manufacturing technology, low noise levels, long service life, high unit efficiency, and reliable operation.

Relevant parameters: flow rate, delivery head, required power, applicable well diameter, compatible cable model, and discharge pipe diameter.
