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. Moreover, CRD920H has an inverter motor, which gives more precise control in vacuum level and saves power. Professional and well-rounded, CRD920H is the perfect choice for high-end applications that require strong and stable vacuum.

Features:

• The pump employs an inverter motor, which can regulate flow rate to achieve a better vacuum control
• Power-saving motor adjusts speed to need
• 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
• For more precise control, users can prepare a variable frequency drive and a pressure sensor to construct a closed loop control system, or purchase our complete vacuum control set
