SKU: UDP-6 Categories: ,

Compact, lightweight, manufactured and imported directly from Japan, ULVAC UDP-6 is a high capacity full chemical-resistant 2-head pump that creates deep vacuum by reciprocate movement of rubber diaphragms. These pumps are oil-free, which means less maintenance and no more frequent and costly oil change, or cross contamination.
