SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. 
Picking the proper dimension pump from one.five cfm to 9 cfm will depend on your precise application. These pumps a single engineered especially to aid you do your job more rapidly and greater.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron discipline rating. Hefty duty large torque motor-assures cold weather staring.
Lower operating temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help decrease working temperature and greater Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Advanced dual-stage style and design pulls deep vacuum to 50 microns. Layout of those 1.five,three,five,eight,10,12 CFM pump improvements build within the performance-proven quality functions. No matter what your vacuum pump needs, the appropriate pump will head to operate with you.
Dual stage design-second stage starts pumping at a decrease stress to pull a deeper ultimate vacuum.
Preventing oil-returning design-prevents pump oil from getting sucked into the technique if a electrical power reduction occurs.
Gasoline ballast-speeds evacuation and keeps oil cleaner. Massive oil reservoir-lightweight and improved dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump can be a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and contains 4 patents; its basic capabilities have a great improvement. Rotary piston vacuum pump is a sort of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(when a fuel ballast applied). The pump needs to be fitted with appropriate accessories if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle demonstrate in functioning 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 transformed repetitively, to ensure that pumping purpose can be achieved.
