Series of submersible motors 6 - 8 - 10 water rewinders, 2-pole asynchronous type, with squirrel cage rotor.Electric winding with PVC wire,easily rewindable. Robust and oversized motors to withstand heavy loads and lasting over time.The radial bearings and the axial bearing are of the Mitchell type, and lubricated by the water inside the motor ; This allows a long period of timeOperation without any maintenance. Themechanical seal, mounted on the crankshaft, allows a particular resistance to presence Of sand.
FEATURES: Wetted wire wrap in PVC (on request PE2 + PA) External motor body stainless steel Upper support and lower support in Cast Iron G25 Upper and lower radial bearings in Grafite Axial bearing in Grafite - AISI 303 Mechanical seal in SiC - NBR - AISI304 Non-toxic filling liquid: water + glycol High performance seal in NBR - AISI304 Motor insulation class Y / B - IP 68 protection shaft protrusion and coupling dimensions to NEMA standards Easily removable and rewindable Y/A triangle star starter possibility
