About This Product

WES1201B is a two-stage electric hydraulic pump with a submerged motor, intended for single-acting cylinders. Maximum operating pressure is 350 bar (5,000 psi), and it includes a 3-way, 2-position, normally open manual valve (advance / retract) and a pressure switch. The motor is 115 V, single phase, 50/60 Hz, 0.5 hp. First-stage flow is 2.45 l/min (150 in³/min) and second-stage flow is 0.65 l/min; first-stage pressure is listed as 1,000 psi (approx. 70 bar). Usable oil capacity is 1.5 gal (347 in³ reservoir) and the relief valve is adjustable from 70 to 350 bar. Sound level is 60–70 dBA. It is used as a hydraulic power source in workholding applications. Country of origin is listed as the United States.

Features and Benefits

  • Two-stage pump provides rapid cylinder advance and reduces cycle times
  • Submerged dual voltage induction motor runs cooler and quieter (60–70 dBA)
