2xz Series Rotary Vane Vacuum Pump

**Product Specifications** **Product Overview** This is a double-stage high-speed oil-sealed rotary vane vacuum pump. It is equipped with a gas ballast valve, which helps to reduce the partial pressure of vapor in the discharge process by introducing a controlled amount of air. This prevents condensation of vapor within the pump oil and avoids oil emulsification, thus extending the life of the oil. However, using the gas ballast valve may slightly lower the ultimate vacuum level and increase the pump's operating temperature. The pump is known for its compact size, lightweight design, quiet operation, and easy starting. It also features mechanisms to prevent oil back-suction and oil leakage from the shaft seal, ensuring environmental protection. **Field of Application** 1. The pump serves as a fundamental component for evacuating sealed vessels. It can be used independently as a main pump or as a forepump for booster pumps, diffusion pumps, and molecular pumps. It can also act as a holding pump in a vacuum system or as a pre-pump for various types of pumps. It is widely used in electro-vacuum industries, vacuum flask manufacturing, vacuum welding, and as an accessory for precision gauges or meters that require a vacuum environment. Its small size, light weight, and quiet operation make it ideal for laboratory use. 2. The pump can operate continuously under atmospheric temperatures ranging from 5°C to 40°C, provided the intake pressure is below 1230 Pa. If the gas being pumped contains more than 90% relative humidity, the gas ballast valve should be opened. 3. The pump must not be operated for more than one minute when the inlet port is fully open to the atmosphere. 4. It is not suitable for pumping oxidized, toxic, explosive, or corrosive gases, nor gases that react chemically with the pump oil or contain dust particles. **Company Overview** - **1988:** Established headquarters in Zhejiang, primarily producing SK series vacuum pumps for the pharmaceutical industry. - **1997:** Established a sales branch in Shanghai. - **1998:** Developed SK-A and SK-D series for the plastic industry. - **2007:** Established a foreign trade department and began international business operations. **Main Products** - Liquid Ring Vacuum Pumps: SK, SK-A, SK-D, 2SK, 2SK-B, 2BEA, etc. - Centrifugal Pumps: IZ(BL), etc. - Rotary Vane Vacuum Pumps: 2X, 2XZ-B, VRD, XD, etc. **Certifications** - CE - ISO 9001:2000 - ISO 14001:2004 **Product Images**
