Welch SCSpro 15 Dy Scroll Vacuum Pump, Self Cleaning, 115 VAC, 60 Hz, 1P. Welch Part Number: 5151-01. 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. 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. 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. FEATURESOil-free deep vacuum Self-cleaning function during operation without impacting vacuum Continuous operation between ultimate vacuum pressure and atmospheric Robust dual voltage/frequency motor Integrated hour meter for accurate servicing Built-in handle for easy transport Modular design allows fast, easy servicing 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
