JOCH Gas Circulation Cooling Roots Vacuum Pump

When used independently with direct exhaust to atmosphere, the operating vacuum can reach 150 mbar.
When used in multi-stage series or combined with other fore pumps, it can achieve the medium vacuum range.
The specially designed structure ensures the pump will not overheat or overload when operating under high pressure difference and high compression ratio.
The three-lobe involute profile structure and high-precision machining ensure stable and quiet operation.
Key performance indicators such as pumping speed, noise and vibration are significantly improved compared with traditional two-lobe pumps.
The advanced balanced mechanical seal provides more reliable sealing performance than traditional lip seals.
The oil-free pump chamber is suitable for pumping ordinary air and various special gases.
Compared with other mechanical vacuum pumps, it features outstanding energy-saving performance.
