220v/380v single stage rotary piston vacuum pump for oil vapor recovery

220v/380v single stage rotary piston vacuum pump for oil vapor recovery gas station

Introduction:      
Piston vacuum pump has single stage and dual stage two types. The pressure of dual stage is lower than that of single stage. This pump can suck gas containing few condensable vapor with its gas ballast open. Equipped with additional device, it can also pump special gas containing superabundant of oxygen, being corrosive to ferrous metal, or having chemical react to pump oil.
Advantage:  
1.Low gravity and power consumption, wonderful stability, small space request, and stable performance.
2.Less oil ejection at discharge port and longer lifetime for vacuum pump oil.
3.With back settled oil tank to prevent oil return to pump chamber.
4.With side flash port on oil tank, convenient for clean and maintenance.
5.With O-ring seal, easy to be disassembled and convenient for maintenance. 
6.Long lifetime for bearing because of newly added sealing between pump chamber and bearing
7.Separate supply port for vacuum pump oil and lubricant. 
8.Few vibration.
Application:
The pump is applicable to vacuum melting, vacuum furnace, thermal processing, vacuum sintering, vacuum metallurgy, vacuum degassing, vacuum drying, vacuum coating, molecular distilling, vacuum impregnation, electronics, solar industries and aerospace simulation test.
