Description

The ruggedness is a result of reduced frictional wear (less than 580rpm vs. typical 1750rpm direct-drive pumps) and high contamination tolerance (contaminants diluted due to large oil capacity).

  • Dual-voltage models come wired for lowest voltage listed in specifications chart; may be converted to higher voltage listed by rewiring
