More About this Item

This new pump is the ultimate set and forget vacuum pump technology for applications requiring a precise vacuum level utilizing all the feature of a standard self-cleaning vacuum system plus many more. Programmable features include selectable vacuum levels, memory for stored programs, and electronic vacuum regulator and a digital absolute pressure gauge. Multi-purposing with this pump is a breeze when you can store settings for one application, and then when finished, easily setup a stored program for another. The control system utilizes an absolute pressure gauge that displays the vacuum level on a 2” 6-digit display and controls the regulator to maintain vacuum to within 1% of the reading. Being a self-cleaning pump there is a programmed cleaning cycle when the pump turns off to remove any vapor buildup inside the pump head which protects the diaphragm and extends the time between required maintenance. The easiest way to be certain the pump will be ready when you are is to order a service kit so that you are prepared for preventive maintenance.
