Rotary Vane Pumps

For applications requiring a greater vacuum depth than an oil-free diaphragm pump can provide, BrandTech offers rotary vane pumps. VACUUBRAND Rotary Vane Vacuum Pumps have been designed from the ground up for the best performance in laboratory applications. They are extremely low noise and low vibration, even compared to earlier VACUUBRAND rotary vane models.

Frequently Asked Questions

1. Which of your gauges should I choose for my vacuum pump?
The DCP3000 + VSP3000 or VACUU-VIEW extended are excellent choices for rotary vane pumps and roots pumps.

2. Can I retrofit a stand/catchpots/condensers/controllers to my pump?
Unfortunately, it is not possible to retrofit solvent recovery glassware to our pumps. However we do offer controllers that will work with your diaphragm or rotary vane vacuum pump, regardless of manufacturer.

3. Why do I need a separate solenoid valve and vacuum fitting for my CVC3000 controller?
Because the CVC3000 is designed to be operated with a huge span of vacuum pumps, we offer several different valves to go with it. Having a separate valve and vacuum fitting also allows the controller and valve to be located at their optimal positions for best vacuum control, and not just what is convenient for the controller. Additionally, while controllers that shut the pump off to control vacuum are less expensive, they can allow condensation inside the pump and produce additional strain on the pump upon restart. If you would like to purchase a controller with the solenoid valve attached as a single unit, consider the CVC3000 detect.

4. My application uses different units than you show in the specifications? How do I know which pump I need?
Our Vacuum Pump Selection Guide contains a Unit Conversion Calculator that will convert these units.

5. Can you cross Pump X from Supplier Y to one of your diaphragm pumps?
It depends. For certain applications, like freeze drying, diaphragm pumps can not achieve the ultimate vacuum required to perform the task. In these cases, we can suggest our low-maintenance RC6 chemistry-Hybrid pump as an alternative. However, for most laboratory applications, selecting the best pump for an application requires a bit more information that just telling which rotary vane pump you used to use, so that you don't pay more than you need to, but get the correct accessories as well. Try our Vacuum Pump Selection Guide, or call our Customer Service department to get a customized recommendation for your application.

6. How do I select a cold trap coolant?
To select the proper coolant for your cold trap, you need to consider several things:7. What do I need to order to fit a hose barb on my vacuum pump?
For example, dry ice has a temperature of -78.5 C. Acetone has a vapor pressure at that temperature of approximately 0.5mbar. So, when operated with a two-stage rotary vane pump, with an ultimate vacuum of approximately 0.001mbar, a dry ice trap would not be effective. A better choice would be liquid nitrogen, with a temperature of -196 C.Of course, a dual-stage rotary vane pump would be overkill to evaporate acetone. If a single-stage diaphragm pump, with an ultimate vacuum of 70mbar was used to evaporate acetone, a dry ice trap would be considerably more effective.To know whether your cold trap is being effective or not, the efficiency can be calculated by weighing your sample before and after drying to determine the mass of the evaporated solvent. This can be compared to the mass of the liquid collected in the cold trap. All of the solvent that is not collected in the cold trap can be assumed to enter the pump. In the case of a rotary vane pump, it can be assumed to be contaminating the oil.
