Large flow channel spiral centrifugal pump submersible pump seal

Wear resistance, double "back-to-back" mechanical seals, equipped with intermediate seal cooling oil chamber

Standard seal specifications: elastomer, rotating surface, static surface

Product side: silicon carbide, silicon carbide, fluororubber

Motor side: carbon, ceramic, NBR

By convention, the product side sealing surface faces the liquid and the motor side sealing surface faces the motor side.

Special order options include gland packing, API seal flush solutions and specialized seal face material-elastomer combinations.

motor

Large flow channel spiral centrifugal pump submersible pumps are usually equipped with IEC motors with a rated operating power 

of 50Hz. There is a growing demand for motor efficiency worldwide, and large flow channel spiral centrifugal submersible pumps are 

suitable for the latest version of high-efficiency IE3 motors. Some models can be equipped with ultra-efficient permanent magnet motors.

Motor ordering options include country-specific voltage, NEMAC and ATEX certified motors and hydraulic or pneumatic drives.
