30kw/40hp Franklin 6 inch Submersible Motor – 904LSS Rew
Franklin 40hp/30kw SAND FIGHTER™ submersible motors are built for superior dependability in sandy well applications. The SAND FIGHTER™ SiC seal system is the standard option for applications in aggressive media. Sand slinger and mechanical seal for high performance in sand.
These 6“ rewindable motors are truly rewindable with removable winding covers. They are designed to operate in 6“ diameter or larger water wells.
The 904L Stainless steel shell provides better corrosion resistance for aggressive media, acid, low pH and seawater applications.
Water lubricated thrust and radial bearings enable a maintenance free operation. A special diaphragm ensures pressure compensation inside the motor. The motor is filled with a special non contaminating FES93 fluid, providing frost protection down to -15ºC storage temperature to +60C.
The motors are made of 904LSS and are prefilled and 100% tested.
High efficiency electrical design to save money on operation costs.
Design for retrofitable PT100 sensor and approved Franklin Electric “Kingsbury Type“ thrust bearing.
