BWSS – Submersible Borehole Motors

MOTOR: Betterline BWSS submersible motors are robustly designed to give exceptional reliability in borehole pumping applications. The
water lubricated thrust and radial bearings enable low-maintenance operation. A preloaded diaphragm ensures pressure compensations
inside the motor. Standard Features include:-
Largely stainless steel AISI 304 construction with cast iron top and bo om bearings
Standard 4” NEMA flanges with studs (M8) for use with all types of pumps (M12 for 6” motors)
Sand slinger and SiC mechanical seal for high performance in sand.
