Vacuum Pumps > Dry Mechanical Pumps > Scroll Pumps > ULVAC Series

ULVAC^® Standard—DIS Series

Excellent alternatives to medium oil-sealed rotary vane pumps.

Features:

• Absolutely oil-free
• Ideal for applications where any possible contamination of the vacuum system by pump oil cannot be tolerated
• Little routine maintenance—no oil changes, no filter or foreline trap replacement, and no oil waste disposal
• DISL Series features increased moisture-handling capabilities

OEM "Drop-In" Replacements:

• Mechanically comparable to Edwards ESDP12, GVSP30 and other manufacturer’s—call for cross-reference

NOTE: These pumps are not suitable for liquids, dust-laden gases, or corrosive gases.
