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.
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.
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.
