vacuum pumps

SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Choosing the proper size pump from 1.five cfm to 9 cfm relies on your certain application. These pumps one engineered particularly to aid you do your task quicker and much better.
Substantial efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Heavy duty large torque motor-assures cold weather staring.
Very low operating temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help reduce operating temperature and much better Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Innovative dual-stage layout pulls deep vacuum to 50 microns. Style and design of these one.five,3,5,8,ten,12 CFM pump enhancements create around the performance-proven high-quality features. What ever your vacuum pump requires, the right pump will go to function with you.
Dual stage design-second stage commences pumping at a lower stress to pull a deeper greatest vacuum.
Preventing oil-returning design-prevents pump oil from getting sucked in to the system if a energy loss happens.
Fuel ballast-speeds evacuation and keeps oil cleaner. Huge oil reservoir-lightweight and improved dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and includes four patents; its common capabilities possess a terrific improvement. Rotary piston vacuum pump is really a kind of vacuum production tools suitable for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilised). The pump should be fitted with suitable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle show in working 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 pumping purpose might be accomplished.
