Three-phase:  220, 230, 380, 460, 575V - 60 Hz     220 , 380V-50Hz

Application Data 

This motor is a reliable motor for use in wells 4" diameter or larger. 

Continuous operation in water at 40°C. 

Direction of rotation; unidirectional, counterclockwise facing the shaft end; three-phase, electrically reversed. 

See KATREENI Electric Submersible Motors :

Applications, Installation, Maintenance Manual" for more information.

Basic Features 

Anti-corrosion all stainless steel shell 

Stainless steel spline shaft 

Airtight stator coil 

Epoxy resin self-healing system

Water lubrication filter type thrust bearing 

Pressure balance film 

Built-in lightning arrester (with single-phase 200 volts, three-phase 230 volts)

Replaceable water blocking lead 

Special Features

Bottom material and sealing method improve corrosion resistance in harsh water environment When the water temperature reaches the target 30 ℃, the 2-horsepower motor does not need a drainage catheter, and the 3-horse power motor needs 8 cm per second of cooling water flow 2-wire motor .It is a split-phase design with integrated starting elements and does not require a control box. This relay provides permanent protection during the operating of the pump.

Typical Applications 

Water supply

Irrigation system 

Lowering of ground water 


Various industrial use 

Working Conditions 

Thin clean non-corrosive liquid without solid particles or fibers 

Temperature : +35°C 

Working pressure : 30 bar

PH value : 6.5~8.5

Submersion depth : no more than 100 meters 

This system is suitable for the circulation and pressurization of clean water and softened water. 

This series is made of 304 stainless steel, which has good corrosion resistance when transporting cold water containing a small amount of hydride. 

It is suitable for slightly alkaline water, demineralized water

316 stainless steel and ammonia rubber pumps are suitable for highly corrosive liquids.
