Product Description

"BOTH" VRD series pumps are designed for reliable long time continuous operation, they will take your equipment's vacuum down to 0.3 micron in minutes. Comes standard with all necessary fittings and a high capacity exhaust oil mist filter which also returns trapped pump oil back to the pump and makes the pump quieter to run. Multi-level gas ballast is designed to allow purposefully pull a less deep and slower vacuum by opening the gas ballast, allowing dry air to go directly into the pump and diluting the vacuum pull, and it also helps keep moisture, solvent, and other contaminants from getting stuck in the pump, and instead passing through to the exhaust. It is important to note that pumps should always be ran in a well ventilated area

· Tow-Shift adjustable gas ballast valve satisfies different requirements of condensable vapor(such as water vapor) to be exhausted
· Out of pump in different processes. Dual protection of oil anti-sucking back ensures vacuum system from oil pollution when pump
· Stops running and needs to be easily restarted. Forced oil circulation system consisted of oil pump and constant pressure oil supply mechanism ensures stable running of the pump.
· Less components are used, easy to maintain and repair


Application
· 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
