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 depends upon your precise application. These pumps one engineered exclusively to help you do your occupation more quickly and much better.
Large efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Hefty duty large torque motor-assures cold weather staring.
Reduced working temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help decrease operating temperature and greater Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Superior dual-stage design pulls deep vacuum to 50 microns. Design and style of those one.5,three,five,8,ten,12 CFM pump enhancements develop to the performance-proven high quality functions. Whatever your vacuum pump demands, the proper pump will head to perform with you.
Dual stage design-second stage begins pumping at a decrease strain to pull a deeper greatest vacuum.
Preventing oil-returning design-prevents pump oil from currently being sucked to the process if a electrical power loss occurs.
Fuel ballast-speeds evacuation and keeps oil cleaner. Significant oil reservoir-lightweight and far better dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It is enormously enhanced series H rotary piston pump and contains four patents; its common abilities have a excellent improvement. Rotary piston vacuum pump is actually a type of vacuum production gear appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast utilized). The pump need to be fitted with suitable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle display in functioning principle graph: A rotary piston with slide valve across eccentric wheel driven by shaft inside 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 modified repetitively, to ensure pumping goal could possibly be achieved.
