Industrial VRD Series Two Stage Rotary Vane Vacuum Pump
● Excellent Performance: Integral cylinder structure, with higher accuracy, proven rotary vane technology, make the performance more stable, ensure the system has higher reliability.
● Great Heat Dissipation: Air-cooled structure, no need for external water cooler, reduce system installation and maintenance costs.
● Forced Lubrication: Built-in gear pump and constant pressure oil supply mechanism forced oil supply, high suction pressure can also be stable and reliable operation.
● Multi-stage Gas Ballasting Design: Meet the vacuum requirements of different customers and water vapor processing capacity.
● Fluorine Rubber Seals: Improve corrosion resistance, to solve the problem of oil leakage.
● Double Anti Oil Returning Structure: Automatic anti oil return valve, more reliably protect your vacuum system from oil pollution after shutdown.
● High Quality Oil Mist Filter (Optional) : Effectively filter oil mist, protect the environment clean.
 
		    
			● Rotary Vane Vacuum Pump corollary use with freezer dryer to reach vacuum state, it’s an essential corollary equipment in medicine freeze drying, biology, food industry and agricultural products deep processing
● Rotary Vane Vacuum Pump corollary use with vacuum drying oven for maintaining vacuum state inside the oven, they mainly applies in powder drying and baking in vacuum condition
