vacuum pumps

SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Selecting the right dimension pump from 1.5 cfm to 9 cfm will depend on your specific application. These pumps one engineered particularly to help you do your task a lot quicker and improved.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Heavy duty large torque motor-assures cold climate staring.
Reduced working temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lessen working temperature and improved 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. Style of those 1.5,three,five,8,ten,twelve CFM pump improvements build to the performance-proven quality characteristics. What ever your vacuum pump needs, the proper pump will visit do the job with you.
Dual stage design-second stage begins pumping at a decrease stress to pull a deeper greatest vacuum.
Preventing oil-returning design-prevents pump oil from staying sucked to the procedure if a power reduction happens.
Gas ballast-speeds evacuation and keeps oil cleaner. Big oil reservoir-lightweight and far better dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It can be greatly improved series H rotary piston pump and consists of four patents; its standard abilities have a excellent improvement. Rotary piston vacuum pump is a sort of vacuum manufacturing tools appropriate for pumping ordinary gases and condensable gases(when a gas ballast used). The pump needs to be fitted with appropriate equipment if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle display in doing work 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, so that pumping function could possibly be attained.
