CW & CCW direction of rotation.

Rewindable, PVC, PP & PE2+PA winding wire

Our rewindable motors provides long service life.

Our motors can be operated horizontally if motors will be installed in
open body of water (i.e pool)


Heavy duty bearings with high thrust capacity

Heavy duty bearings provides the option to revolve both sides, has the capacity to carry high thrust load.

Water lubricated radial carbon bearings

Radial carbon bearings, which have channels in its structure that makes it possible to get lubricated by
water easily, provides precise bearing of rotor shaft at up and down.

Chrome-plated bearing collet

Chrome-plated and precisely machined bearing collets which are located in the radial bearings operating area,
have great importance for bearing the rotor.

Mechanical sealing system for high sand resistance and degree of protection: IP68

Although mechanical seal is optionally used by other companies, it is always used by Vansan as a standard,
to prevent sand and other particles to get in motors to provide long bearing life.

Pressure balancing checkvalve

Pressure balancing checkvalve controls the pressure changes inside the motor. When the pressure increases,
it throw water out of the motor.When the pressure drops, it filtrates the water inside well and gets it inside the motor by
the help of this checkvalve to balance the pressure inside. That's why pressure differences inside motor never causes
membrane under motor to blow up.

Practical and easy-to-mount output power cable

Connection of the power cable to body is made practically by cable seal and seal cover.
Power cables can be changed easily without any damage.

PT100 Overheating protection

By connecting the PT100 thermal sensors to the slot that is standardly placed on upper bearing body, motor temperature values can be easily measured.

Up-Thrust ring

Provides safe operation conditions for motor by absorbing Up-Thrust loads with it's machined surface and water channels on it.

Cable connection

Preventing the water inside the motor to run through the cable and reach connection parts of power cables by specially designed cable seals.

Adjustment screw

Standard shaft height can be precisely adjusted by the
adjustment screw on the thrust bearing base.


Membrane minimizes the expansion pressure that is caused
by heating of cooling water's inside the motor

Slinger (sand guard)

Slinger helps to prevent the sand inside the water of the well entering in
mechanical seal and through mechanical seal to inside of the motor.
