I have been using contact seals such as O-rings or oil seals for the rotating shafts in vacuum chambers.
Can I replace these with ferrofluidic feedthroughs ?
What are the advantages of ferrofluidic feedthroughs ?
Yes, you can replace with Ferrofluidic Feedthroughs.
Advantages:
(1) Improve the vacuum cleanliness and extend the service life;
(2) High vacuum level and zero leakage;
(3) Wide application from low speed to high speed, from low pressure to high pressure, from low temperature to high temperature.
What’s the source of the ferrofluid ? Self-research or buy from abroad ?
Vigortec researched the Ferrofluid by ourselves and we have our own patent ZL2008 10062727.7.
What’s the temperature range for ferrofluidic feedthroughs ?
The normal temperature range 0~80°C, We can add water cooling for high-temperature or low-temperature applications. Now, Vigortec have the actual performance of maximum temperature 1000°C and minimum temperature -40°C.
Can Ferrofluidic Feedthroughs be used for liquid stirring device?
Yes, Ferrofluidic Feedthroughs can be used in liquid stirring device for food industry and biology&medince industry and so on.
However, please notice that liquid cannot be in touch with Ferrofluid directly.
Can Ferrofluidic Feedthroughs be used in Vacuum adsorption equipment?
Yes, Ferrofluidic Feedthroughs can stick to the sample and rotate at high speed.
Can Ferrofluidic Feedthroughs be used for Gas import equipment?
Yes, Vigortec have used Ferrofluidic Feedthroughs at more than one gas import equipment such as reactant gas and purge gas.
Can Ferrofluidic Feedthroughs be used in corrosive-gas environments?
Yes, but It depends on the species, density of the gas.
Delivery lead time?
The normal delivery lead time is 3~4 weeks. Certainly, we can try our best to shorten the delivery time when customers have urgent requests.
How long of the Ferrofluidic Feedthroughs’ life? How often should Ferrofluidic Feedthroughs be overhauled?
Its life depends on your application conditions. Normally, it can be more than 10years.
Does Vigortec provide repair service? What about the repair costs and lead time ?
Vigortec provides repair services for all Ferrofluidic Feedthroughs.
Costs:
The repairing costs is about 1/3~1/2 of a new product price. But, It varies depending on repair work.
Repair lead Time:
Generally it takes about 2~3 weeks after get the repair products.
What is the warranty period for Ferrofluidic Feedthroughs?
Vigortec’s warranty is 12 months for new products and 6 months for repaired products.
What accessories will be included with shipment ? such as O-rings, keys or water-cooling fittings included with shipment?
Generally, it will include O-rings, water-cooling fittings.
If you need some special accessories such as keys and pulleys, please note when placed orders or please provided by yourselves.
When need water-cooling for Ferrofluidic Feedthroughs, what is the applicable flow rate and pressure of cooling water?
The flow rate of 1L/min should be fine. The max pressure is 0.5MPa.
