WOB-L® 2522

Standard Duty Piston Pump

  • Effective for standard duty applications, not strongly acidic, basic or organic vapors
  • Lightweight, compact piston pump
  • Comes with inlet liquid trap, vacuum regulator, water trap and muffler
  • Oil-free operation for reduced maintenance
  • High water vapor tolerance
  • Available in 115V/60Hz(2522B-01)
  • Free air displacement @60Hz: 0.76 cfm (22 L/min)
  • Ultimate pressure: 100 Torr (133 mbar)

Welch SCSpro 15 dry scroll vacuum pump generates a maximum pumping speed of 250 lpm and vacuum to 0.012 Torr(0.016 mbar). The oil-free scroll pump generates a vacuum by continuously moving pockets of captured gas that enters inlet to exhaust port via two-sided spiral mechanism.

Welch SCSpro 15 has a built-in self-cleaning air flush that removes liquefied vapors that can condense in pump from a trapped application. The air flush function doesn’t impact vacuum performance of pump.

The scroll pump is an alternate solution to oil-sealed rotary vane pumps. Common applications include freeze dryer with ultra-low temperature condenser, glove box, cold trapped vacuum oven or degassing chamber, turbo backing, and evacuation of cryogenic lines.

The SCSpro 15 is made to last with durable and reliable materials, in which:

• Scroll and body are made of anodized aluminum.

• Tip seal is made from PTFE composite.

• Exhaust valve is made with FKM.

• Inlet and exhaust ports are made from cast stainless steel
