SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Choosing the proper dimension pump from 1.five cfm to 9 cfm will depend on your particular application. These pumps one particular engineered specifically to assist you do your work faster and better.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Heavy duty higher torque motor-assures cold weather staring.
Very low working temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help cut down working temperature and better Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Superior dual-stage layout pulls deep vacuum to 50 microns. Layout of these one.five,three,five,8,ten,12 CFM pump enhancements construct around the performance-proven high-quality options. Whatever your vacuum pump desires, the ideal pump will go to work with you.
Dual stage design-second stage commences pumping at a lower stress to pull a deeper greatest vacuum.
Preventing oil-returning design-prevents pump oil from becoming sucked in to the system if a energy reduction happens.
Fuel ballast-speeds evacuation and keeps oil cleaner. Big oil reservoir-lightweight and superior dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is a 
form of single-stage and single-cylinder rotary piston vacuum pump. It’s enormously improved series H rotary piston pump and includes four patents; its common capabilities possess a terrific improvement. Rotary piston vacuum pump is a sort of vacuum production gear ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast employed). The pump must be fitted with appropriate add-ons if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle show in working principle graph: A rotary piston with slide valve across eccentric wheel driven by shaft within 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 changed repetitively, to ensure pumping function could be accomplished.
