About This Product

WES1401B is a two-stage submerged electric hydraulic pump from the Enerpac WE series. Because the motor runs submerged in oil, it stays cooler under intermittent use. It is designed for use with single-acting cylinders. Maximum operating pressure is 350 bar (5,000 psi), first-stage pressure rating is 1,000 psi, and output flow is 2.45 L/min in the first stage and 0.65 L/min in the second stage. The motor is 0.5 hp, 115 V, 1 phase, 50/60 Hz, with a sound level of 60-70 dBA. The valve is 4-way, 3-position, tandem center, manually operated (advance / hold / retract). It is used as a hydraulic power source in workholding applications. The relief valve adjustment range is 70-350 bar and the usable oil capacity is 1.5 gal (about 5.7 L).

Features and Benefits

  • Two-speed pump unit provides rapid cylinder advance and reduces cycle times
  • Submerged dual voltage induction motor runs cooler and quieter (60-70 dBA)
  • Externally adjustable relief valve, no need to open the pump to reduce pressure (70-350 bar)
  • Reservoir mounting holes for easy mounting to a fixed surface
  • Full length side tube for easy monitoring of oil level
  • Auxiliary return port eliminates the need for a separate adapter
