SINGLE STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Single stage vacuum pumps operate on 110 VAC or 220VAC. Choosing the appropriate dimension pump from 1.5 cfm to 9 cfm relies on your particular application. These pumps 1 engineered especially to assist you do your career faster and better.
High efficiency-CFM rated as ?¡ãfree air displacement.?¡À150micron field rating. Hefty duty substantial torque motor-assures cold climate staring.
Minimal working temperature-improve efficiency and vacuum.
Forced-feed lubrication design-help lower operating temperature and better Lubrication.
DUAL STAGE VACUUM PUMPS
110/220VAC Vacuum Pumps
Dual stage vacuum pumps operators on 110 VAC or 220VAC.Advanced dual-stage design pulls deep vacuum to 50 microns. Design and style of those one.5,3,5,8,ten,12 CFM pump improvements develop over the performance-proven high quality capabilities. No matter what your vacuum pump requirements, the correct pump will visit function with you.
Dual stage design-second stage begins pumping at a lower stress to pull a deeper greatest vacuum.
Stopping oil-returning design-prevents pump oil from remaining sucked into the system if a energy loss happens.
Gas ballast-speeds evacuation and keeps oil cleaner. Huge oil reservoir-lightweight and greater dilute corrosive contaminants.
ROTARY PISTON VACUUM PUMPS
The series HGL, HG pump is actually a variety of single-stage and single-cylinder rotary piston vacuum pump. It is significantly improved series H rotary piston pump and contains 4 patents; its general capabilities possess a wonderful improvement. Rotary piston vacuum pump is really a kind of vacuum manufacturing products ideal for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump should be fitted with suitable equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. Operation principle present 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, so that pumping purpose may be achieved.
