110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Selecting the appropriate size pump from 1.5 cfm to 9 cfm depends upon your certain application. These pumps one engineered specifically to assist you do your task quicker and much better.
Large efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Heavy duty high torque motor-assures cold climate staring.
Reduced working temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lower operating temperature and much better Lubrication.
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Innovative dual-stage design and style pulls deep vacuum to 50 microns. Style of those one.5,3,5,8,ten,twelve CFM pump improvements create over the performance-proven good quality features. What ever your vacuum pump demands, the correct pump will visit function with you.
Dual stage design-second stage begins pumping at a reduced strain to pull a deeper greatest vacuum.
Avoiding oil-returning design-prevents pump oil from remaining sucked to the system if a energy loss takes place.
Fuel ballast-speeds evacuation and keeps oil cleaner. Large oil reservoir-lightweight and greater dilute corrosive contaminants.
The series HGL, HG pump is really a variety of single-stage and single-cylinder rotary piston vacuum pump. It is considerably enhanced series H rotary piston pump and includes four patents; its general abilities possess a wonderful improvement. Rotary piston vacuum pump can be a type of vacuum production gear appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast utilized). The pump have to be fitted with acceptable equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle present in working principle graph: A rotary piston with slide valve across eccentric wheel driven by shaft inside of the housing. Piston pole can slide and swing freely in arch track. The entire pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are modified repetitively, to ensure pumping function may be attained.
