You might have a need for the Dekker Duravane System. This system makes use of rotary vane vacuum pumps. These are lubricated rotary vane pumps – single-stage, that integrates a closed-loop system for oil circulation. Oil-free (or dry) rotary vane vacuum pumps are also an option, however, those are used less frequently than the lubricated.
The Dekker DuraVane is used in a variety of industries such as vacuum packing, lifting, chucking, paper converting, electronics, printing, biotech, laboratories and hospitals. Although heavy-duty, its compact construction results in a small footprint. Vane material delivers 50,000 hours of vane life when utilizing lubricated rotary vane pumps.
These vacuum pumps have an internally located inlet check valve and are direct powered by a flange-mounted motor. The pump will use a high-efficiency, multistage exhaust filter to remove 99.9% of oil mist. The Dekker Duravane is equipped with a gas ballast valve.
The major purpose of this valve is to keep water vapor from condensing resulting in emulsification of the lubrication oil. This could lead to pump seizure. If the pump doesn’t reach the proper ultimate vacuum, it might be because the oil has become contaminated with process vapors or perhaps, water. In order to clean the pump, you should fully close the inlet valve.
At that point run the pump for approximately a half hour. This can remove any condensable products from the oil. If, at that point the pump still doesn’t reach ultimate vacuum you should shut the pump down and do an oil change. In order to have the best pump performance, you should always use the properly suggested DuraVane oil.
DuraVane lubricated rotary vane vacuum pumps for saturated air (wet) service are specifically developed for applications with high inlet water vapor content such as stone and glass cutting.
