High Quality Double Stage Rotary Vane Vacuum Pump

Product Overview

This is a high-performance, double-stage, oil-sealed rotary vane vacuum pump designed for efficient and reliable operation. It features a gas ballast valve that allows the introduction of air into the exhaust chamber, reducing the partial pressure of vapor in the discharge gas. This helps prevent condensation of vapor within the pump oil, thus avoiding oil emulsification and extending the life of the oil. However, when the gas ballast valve is open, the ultimate vacuum level may decrease slightly, and the operating temperature of the pump may increase.

Known for its compact size, lightweight design, quiet operation, and ease of starting, this pump is ideal for various applications. It also includes safety mechanisms to prevent oil back-suction and oil leakage from the shaft seal, ensuring environmental protection and smooth performance.

Application Field

1. This pump is a fundamental equipment used to evacuate 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 serve as a holding pump in vacuum systems or as a pre-pump for various types of pumps. It is widely used in the electro-vacuum industry, vacuum flask manufacturing, vacuum welding, and as an accessory for precision gauges or meters requiring a vacuum environment. Its small size, light weight, and quiet operation make it particularly suitable for laboratory use.

2. The pump can operate continuously for many hours under atmospheric temperatures ranging from 5°C to 40°C and intake pressures below 1230 Pa. If the gas being pumped contains moisture with a relative humidity exceeding 90%, the gas ballast valve should be opened.

3. When the inlet port is fully open to the atmosphere, the pump should not run for more than one minute.

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.
