SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Selecting the right size pump from one.5 cfm to 9 cfm depends upon your specific application. These pumps 1 engineered particularly to help you do your occupation more rapidly and much better.
High efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron discipline rating. Hefty duty high torque motor-assures cold climate staring.
Very low operating temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lower operating temperature and improved Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.State-of-the-art dual-stage design and style pulls deep vacuum to 50 microns. Style of these 1.5,3,five,8,ten,twelve CFM pump enhancements establish on the performance-proven high quality capabilities. No matter what your vacuum pump requires, the right pump will go to operate with you.
Dual stage design-second stage commences pumping at a lower stress to pull a deeper greatest vacuum.
Avoiding oil-returning design-prevents pump oil from staying sucked into the program if a energy loss happens.
Gas ballast-speeds evacuation and keeps oil cleaner. Large 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 tremendously improved series H rotary piston pump and contains four patents; its standard capabilities possess a good improvement. Rotary piston vacuum pump is really a kind of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump have to be fitted with suitable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle demonstrate in operating 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 that pumping function might be accomplished.
