2XA Series High Capacity Two Stage Vane Vacuum Pump 0.06Pa Ultimate Pressure For Labs

2XA Series High Capacity Two Stage Vane Vacuum Pump With 0.06Pa Ultimate Pressure For Labs

Product Overview

The 2XA series two-stage oil-lubricated rotary vane vacuum pump adopts high-speed direct-coupled two-stage structure for deep high vacuum. Fitted with specially designed gas ballast valve, it prevents water contamination of vacuum oil and extends oil service life while maintaining excellent vacuum level. The pump uses mature international design, small footprint, light weight, low noise and convenient startup. Built-in forced automatic oil supply mechanism allows stable operation even under atmospheric pressure. It features reliable anti-return oil and zero leakage performance, no environmental pollution. This pump can run independently for gas extraction or act as fore pump for booster pumps, diffusion pumps and molecular pumps.

Key Features and Benefits

Two-Stage Deep Vacuum Structure

Two-stage series compression structure achieves ultra-low ultimate pressure as low as 6×10⁻² Pa, meets high-vacuum process requirements.

Built-in Gas Ballast Valve

Special gas ballast valve prevents water vapor from mixing into vacuum oil, prolong oil service cycle and retains good vacuum performance when gas ballast is open.

Forced Automatic Oil Feed System

Independent oil pump assembly supplies lubricating oil actively; the pump can start and operate normally at atmospheric pressure.

Anti-Backflow & Oil Tight Design

Effectively prevents oil backflow, eliminates oil leakage and avoids oil contamination to vacuum chamber and surrounding environment.

Compact, Light & Quiet Operation

Optimized body layout, small volume and light weight. Low running noise, simple startup and easy on-site installation.

Versatile Working Role

Can be used as standalone vacuum pump, or pre-pump / backing pump for diffusion pump, molecular pump and booster vacuum systems.

Working Principle

This two-stage rotary vane vacuum pump consists of two series-connected pumping chambers. Rotors and sliding vanes rotate at high speed, and vacuum oil serves for sealing, lubricating and cooling. Gas is compressed step by step through the first stage and second stage cavity to obtain far deeper vacuum than single-stage vane pumps. The gas ballast valve injects dry air to dilute condensable vapor and protect vacuum oil.
