SUMOTO SUBMERSIBLE

Sumoto is one of the world's manufacturers leader in the production and marketing of submersible motors for deep well pumps of 3'', 4" and 6".







SMALL SIZE GREAT QUALITY

Thanks to its range of 3" submersible motors denominated OP3, Sumoto is now able to offer a valid instrument for the solution of problems due to well dimensions.
The OP3-type is the outcome of a consistent design effort arisen from the need to solve all the problems due to reduced space.
The motor still preserves the splined-shaft coupling system typical of the NEMA regulations.
The electromechanical specifications are undoubtedelly interesting and complying with all application requirements.
Each motor is suplied with 1.8 mt-long sealed cable direcly connected with the winding.

TECHNOLOGY DRESSED IN STEEL

By using the most advanced design and manufacturing technologies SUMOTO has introduced the INT4" series for deep well pumps. These canned type motors have all the necessary features to assure reliability, durability and efficient operation.

APPLICATIONS

Built for coupling with submersible multistage high and low load thrust 4" pumps for clean water deep well.



-Filling liquid
Water with food grade compound for cooling and lubricating rotor, radial and thrust load bearing.
-Nema coupling
-Shaft sealing system
Includes a labyrinth seal with a sand slinger for an effective sand protection. A lip seal prevent inside coolant fluid exit.
-Electric cable
Removable four wires polychloroprene flat cable with watertight connector with integral earthing system.
-Stator room is resin filled. Under vacum resin filling method gives maximum heat exchange rate and superior dieletric insulation characteristic.
-For a better corrosion resistance motor frame and motor base end cover are made out of AISI 304 stainless steel. Shaft end is made out of AISI303 ss. Upper side bracket is made out of cast iron, nickel plated .
-Bearing system
Unique design hydrodynamic thrust bearing fulfils ideal non contacting operation, providing less wear and assuring long bearing lifetime. Low thrust 3000N class, Kingsbury type with spherical shaped sliding pads. High thrust 6500N class, one simple piece flat surface pad with flexible function(patent pending). The combination of high-tech material on radial bearing ensures durable operation under tough application. Low thrust 3000N class, carbon-graphite radial bearing, mating AISI 303 ss burnished shaft portion. High thrust 6500N class, ceramic radial bearing, mating tungsten carbide shaft sleeve.
