Stainless Steel Submersible Borehole Motor
For 4" & 6" Well Casing Diameter
High Quality Thrust Bearings
The trust bearing is of the kingsburry type lubricated by the internal fluid. 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.
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.
