Reactors and Synthesis Applications

In kilo labs and pilot plants, materials are produced in quantities of a few hundred grams to several kilograms for pharmaceutical development, safety studies and early clinical trials for new drugs. Based on their extraordinary chemical resistance, our high-performance chemistry diaphragm vacuum pumps are perfectly suitable for these applications. The pumps operate without fluids such as water or oil, and thus reduce operating and maintenance costs. Variable-speed pumping systems offer unique control advantages in these applications, and are easily integrated into process control via PC or programmable logic controller.

Process requirements

• a wide range of chemicals are used and many different process parameters are required
• high reliability of technical plant components for days of continuous duty operation
• medium to high vacuum requirements, both in vacuum depth and pumping speed
• frequent use of large amounts of volatile solvents that can create hazardous atmospheres
• controlled and reproducible process parameters

Pump requirements

• high resistance against aggressive chemicals
• high pumping speed over a wide pressure range
• low ultimate vacuum even with open gas ballast for continuous condensate purge
• precise vacuum control via speed-controlled pumps and ease of integration into process control systems
• compatibility with vapors of inflammable solvents, and/or ATEX compatibility in potentially explosive atmospheres
