SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Choosing the correct size pump from one.5 cfm to 9 cfm is dependent upon your precise application. These pumps one particular engineered especially to help you do your task quicker and improved.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron area rating. Heavy duty substantial torque motor-assures cold climate staring.
Very low operating temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lower working temperature and greater Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Sophisticated dual-stage layout pulls deep vacuum to 50 microns. Style of these one.5,three,5,eight,10,twelve CFM pump enhancements create over the performance-proven high-quality functions. No matter what your vacuum pump requirements, the correct pump will go to operate with you.
Dual stage design-second stage begins pumping at a decrease pressure to pull a deeper ultimate vacuum.
Stopping oil-returning design-prevents pump oil from staying sucked in to the system if a energy reduction occurs.
Gasoline ballast-speeds evacuation and keeps oil cleaner. Huge oil reservoir-lightweight and much better dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It is greatly improved series H rotary piston pump and incorporates 4 patents; its standard capabilities possess a wonderful improvement. Rotary piston vacuum pump is usually a sort of vacuum production products appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilized). The pump needs to be fitted with ideal accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle show in operating 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 whole pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are transformed repetitively, in order that pumping purpose may be accomplished.
