The powerful CRD diaphragm vacuum pump series is one of our most popular pumps. Similar to the ACD series, CRD pumps are oil-free, avoiding the hassles and danger of contaminated oil and water. PTFE and PVDF parts provide outstanding chemical and heat resistance. However, CRD series work on a high power of 370W, which generates higher flow rates and higher levels of vacuum. This speed and performance allow CRD vacuum pump to be used in a wide variety of applications, including rotary evaporation, vacuum drying, distillation and so on.


  • The pump can achieve higher flow rates and vacuum levels compared to the ACD series
  • All parts that come in contact with gas are made of PTFE and PVDF, which provide the pump with the ability to withstand hot vapors, liquid condensation and aggressive gases
  • PTFE diaphragm adopts a special “sandwich” structure that enhances its lifetime
  • Suction chamber and motor are segregated to maximize durability
  • Diaphragm pumps are oil-free pumps, which avoid contamination and reduces maintenance hassles
  • Compared to water aspirators, diaphragm pumps provide a more stable vacuum and save water
  • Noise and vibration are minimized to reduce distraction
  • High enclosure ratings allow pump to be used in harsh environments
  • The pump will automatically shut down when pump overheats and resume when temperature returns to normal
  • Power protection for additional safety
  • Users can use vacuum regulators with the pump to control the vacuum level
