STAINLESS STEEL SUBMERSIBLE BOREHOLE MOTOR FOR 4" & 6" WELL CASING DIAMETER - MS4-30-3-2-T

The diameter of the borehole is usually around
 120 to 160 mm, and its depth can reach up to 300
 meters, although depth ​​of about 40 meters is
more common. Your pump and its control system
 must also meet the specific conditions as well
 as the high demands on reliability.
This depends upon the depth of the borehole
 to ground level and then the distance from the
 ground level to the final end point e.g. 
where the water tank is sited. 
The further the distance, the higher 
the pressure requirements of the borehole pump
 to prevent the water from trickling out.
Submersible borehole pumps are a type
 of submersible pump. They are centrifugal
 pumps driven by a submersible motor.
 As they usually draw in the fluid directly without a suction line,
 they must constantly be submerged in the fluid handled.

Stainless Steel Submersible Borehole Motor
For 4" & 6" Well Casing Diameter

High Quality Thrust Bearings
The trust bearing is of the kingsburrytype lubricated by the internal fluEd. During operation a wedge of water is drawn between the stainless steel pivot shoes and carbon disc to carry the thrust load generated by the pump. Located inside and at the bottom of the motor, the bearing is sealed away from sand and other contaminants.

Sand Resistant Slinger and Lip Seals
A stainless steel slinger and slinger guide are also closely fit to help prevent sand entry. Double rubber seals are installed to prevent well water and contaminants from entering the motor.

High Reliable Carbon Bearing
Two water lubricated carbon bearings are used as guide bearings. These have extremely large surface area and result in extra alignment support-less whipping and acts as a steady bushing.

Water-Filled Design
The motor lubrication is provided by the internal cooling water consistings of a water, anti-freeze and anti-rust mixture good to 30°C (-22°F). This mixture is installed at the factory. Two water plugs are located near of the top of the motor and are used by the installer to check the water level or to the top off needed before installation.

Complete Corrosion and Water-Tight Protection
All main motor components are made of stainless steel: including the can housing (water tight type motors have baked epoxy coated steel housing), Shaft and bolts. All other motor parts are coated with the baked epoxy coating.
