H-30 H-150 H-600 Rotary Piston Spool Valve Slide Valve Guiding Valve Vacuum Pump

Introduction of Rotary Piston Vacuum Pump
Here are two kinds of the rotary vacuum pump:
model H single-stage rotary piston vacuum pumps and model 2H double-stage rotary piston vacuum pumps.
Rotary piston vacuum pump is suitable for extracting air and other general gases. When use gas ballast, it can also extract a small amount of condensable gases (such as steam).
Additional devices shall be installed when extracting gases with high oxygen content, explosive, corrosive to ferrous metals and and When extracting gas that chemically reacts with vacuum oil.
This type of pump can be operated singly or as the front stage pump of high vacuum pumps such as diffusion pump, oil booster pump and roots pump.
Compared with rotary vane vacuum pump, H-type slide valve pump is more durable and has a long service life.
Application:
The pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation and aviation simulation tests.
characteristic:
1. Optimized design of counterweight, has less vibration and low noise.
2. The bearing seal chamber supplies oil separately and is separated from the pump chamber, to avoid seal damage prematurely caused by impurities entering the bearing.
3. According to the user's requirements,Auxiliary oil tank can be attached to cool the vacuum oil and separate impurities.
