18B4B - Diffusion Vapour Booster Pump, 3Ph 380-440V Temperature & Oil Level Monitoring

Diffusion Pumps

Vacuum diffusion pumps are essential for creating high-vacuum environments in various industrial and research applications. They operate by heating a special lubricant (often silicone oils) to produce a high-speed jet of vapour, which directs gas molecules towards the pump’s exhaust. This process allows the pump to achieve very low pressures. They require a mechanical fore vacuum pump to operate.

Vapour Booster Pumps

Vacuum vapour booster pumps are designed to enhance the performance of vacuum systems by providing high pumping speeds at intermediate pressures, bridging the gap between mechanical boosters and traditional diffusion pumps. These pumps work by using vapour jets to capture and compress gas molecules, effectively increasing the overall efficiency of the vacuum system.

18B4B

The Edwards 18B4B vapour booster pumps offer higher pumping speeds, of up to 6000 l/s at pressures intermediate between mechanical boosters and diffusion pumps. Vapour boosters from Edwards have been proven in the field for over 30 years. With a constant program of updates and modernisation, with input from OEM’s and end users, combined with inherent reliability, ease of use and tolerance to various inlet and exhaust pressures they have been used extensively in metallurgy and coating industries as well as other specialist applications.

Features and Benefits

• Higher Pumping speed in mid vacuum range
• Simple to operate and long service life
• Suitable for harsh duties as they are tolerant to dust and dirt
• Industry proven with large installed base
