2XZ Series Two‑stage Direct‑coupled Rotary Vane Vacuum Pump
The 2XZ series two‑stage direct‑coupled rotary vane vacuum pump is basic vacuum‑generating equipment for evacuating gas from sealed containers. The motor is directly connected to the pump body, featuring compact structure, small footprint, light weight, low noise and convenient start‑up.
This pump works for dry clean air. It is NOT suitable for pumping gas with excessive oxygen, flammable & explosive gas, corrosive gas, gas chemically reactive with vacuum pump oil, or gas containing large amounts of dust.
Features
• Two‑stage design delivers high ultimate vacuum performance.
• Direct‑drive connection reduces transmission loss and ensures stable operation.
• Built‑in oil‑gas separation device effectively prevents oil spitting.
• Simple structure for easy maintenance and service.
Applications
Widely used in vacuum packaging, vacuum drying, vacuum degassing, vacuum coating, laboratory scientific research, medical equipment supporting and other vacuum‑related processes.
