VSM HT Submersible Motors (6”-7”-8”-10”)

Winding with PE2 + PA insulated wires, the VSM HT Submersible Motors provides superior performance compared to the other types of submersible motors. The HT submersible motors can reach much higher powers (about 20% more) than other submersible pump motors. These motors also demonstrate excellent performance at well water of 50 ºC. The abbreviation “HT” reprensents the first letters of ” High Temperature ” in English

PE2 – PA Wire

Excellent performance at well water of 50 °C. High resistance against valtage surges. 20% more power than normal motors.

Thrust Bearing

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

Mechanical sealing

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.

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.

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 easilly without any damage.

Pressure Balancing Checkvalve

Pressure balancing checkvalves 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 checkvalves to balance the pressure inside. That’s why pressure differences inside motor never causes membrane under motor to blow up.
