WELCH Duoseal, Pump 115V 60Hz 1PH Explosion Proof MOTOR, 5.6 CFM

Welch Belt-drive vacuum pumps are known for their ruggedness world-wide in the most demanding applications

• Low pump rpm to reduce frictional wear while minimizing reservoir temperature to lessen chemical activity
• High oil feed to pump models leads to cleanest oil lubricating the internal pump module
• Large oil reservoirs dilute contaminants ingested into the pump
