Motors

Green Country Submersible Pumps manufactures three-phase induction motors which are hand wound with Kapton and ML coated magnet wire. Our most common motors are two pole 50 and 60 Hertz motors which operate at approximately 2,915 rpm and 3,450 rpm.

Our motors are filled with di-electric motor oils to lubricate the internal structure. The oil also serves as a coolant by transferring heat produced by the intercore of the motor to the housing unit. Well fluids flow past the housing to the intake ports of the pump and provide coolant for the motor.

A wide variety of horse power rating and voltages are available to meet our customers' requirements. 

Protectors

The protector isolates the motor oil from well fluid and provides a reservoir of oil for the motor making it serve as an equalizing chamber. The protector serves as an internal pressure regulator for the motor. The protector responds to the ambient change and heat expansion when the unit is placed in operation. The thrust bearing chamber accepts the load of the fluid column on start up and absorbs the thrust created by the pump.

Pumps

Green Country Submersible Pumps are centrifugal consisting of impellers and diffusers in multi-stage applications. The multi-stage pumps are designed to lift large volumes of oil, brine, and water. Centrifugal pumps are designed for individual well conditions by varying the number of stages and by varying the design of the impellers. The number of stages required determines the total amount of lift provided and the amount of horsepower required. To protect against abrasion, corrosion, and high temperatures, stages are made of Ni-Rest and Ryton materials.  Shafts are made of K-500 monel.

Gas Separators

In high G.O.R. wells, a gas separator may be utilized to replace the standard bolt on intake. The gas separator is designed to eliminate gas deposits and force free gas to pass the pump and vent into the casing annulis. The utilization of a gas separator discourages surges, cycling, and gas locked pump conditions which results in peak efficiency and maximum production.

Impellers

Green Country Submersible Pumps has designed, engineered, and developed a method of manufacturing the Ryton impeller as a "one piece" impeller to replace the previous method of sonic welding the top and bottom portions of the impeller together. Our new one piece impeller provides higher efficiency and longer run life.
