SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Selecting the proper size pump from one.5 cfm to 9 cfm relies on your certain application. These pumps a single engineered specifically to aid you do your career a lot quicker and much better.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Hefty duty high torque motor-assures cold weather staring.
Reduced operating temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lower operating temperature and much better Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Sophisticated dual-stage design and style pulls deep vacuum to 50 microns. Style and design of those 1.5,3,5,eight,ten,12 CFM pump improvements establish over the performance-proven high-quality features. No matter what your vacuum pump requires, the right pump will visit do the job with you.
Dual stage design-second stage commences pumping at a lower strain to pull a deeper ultimate vacuum.
Avoiding oil-returning design-prevents pump oil from getting sucked to the program if a energy loss takes place.
Gas ballast-speeds evacuation and keeps oil cleaner. Large oil reservoir-lightweight and improved dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is really a type of single-stage and single-cylinder rotary piston vacuum pump. It is greatly enhanced series H rotary piston pump and involves four patents; its common abilities have a wonderful improvement. Rotary piston vacuum pump is really a type of vacuum production gear suitable for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump should be fitted with acceptable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle present in doing work 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 modified repetitively, in order that pumping goal might be attained.
