Key Features

Enclosed design prevents air exchange between the motor’s interior and exterior, with a rotor fan circulating internal air to transfer heat to enclosed components and an external fan blowing ambient air over the motor for effective cooling.

Material and lubrication system
  • Oil-lubricated motors ship with empty bearing oil reservoirs; bearings retain a thin oil film, but reservoirs must be filled after three months of storage, with prominent labeling advised to avoid improper operation, oil leaks, or damage to internal parts.
  • Two angular contact ball thrust bearings at the motor’s top manage upward or downward thrust, while a lower radial ball bearing handles pump-induced radial loads.
Corrosion-resistant materials
  • Motor body features cast steel, oxygen-free copper windings, and a squirrel-cage rotor with integrated upper and lower cooling fans.
  • Paired vertical turbine pumps use heat-resistant ductile iron, 2Cr13 stainless steel, or 304/316 stainless steel, ideal for impure or corrosive water.
  • Geothermal deep-well pumps incorporate slender pump bodies with high-temperature, corrosion-resistant materials, withstanding high-pressure subsurface conditions.
