Vacuum Pumps and Generators
We sell a range of industrial CNC vacuum pumps and generators such as; liquid ring, dry running, vane type, Becker pumps, oil lubricated and side channel blowers.
A vacuum pump choice is often one of the most difficult aspects when building a CNC vacuum system, but it needn't be with a little help from us.
All our vacuum pumps are covered by a 1 year manufacturers warranty.
In the video below we show the difference in holding force between a vacuum cleaner which is commonly used in a the hobby cnc industry and an industrial rotary vane pump.
A vacuum cleaner has a holding force similar to a low pressure side channel blower. Side channel blowers are very useful where there is a lot of cross porosity leakage for example with MDF or foams.
They do however have a MUCH lower holding force than a dedicated pump where there is minimal leakage and you should always consider a rotary vane pump over a blower when the material is airtight due to the massively increased forces.
Liquid ring pumps
Are particularly suitable for machining with large amounts of coolant, as they combine both a vacuum pump and liquid separator.
Dry-running, vane type rotating pumps
Can be used for wet machining, if a liquid separator is also added but for flood cooling a liquid ring pump is recommended.
They are however very low maintenance because they do not require lubrication.
Oil lubricated, vane type rotating pumps
Provide very high vacuum. Higher than a dry-running pump but they do require some maintenance and regular oil checks. The main application of these pumps is for dry cutting.
Again these pumps should be used with a liquid separator if they are to be used with quantities of coolant.
Side channel blowers
Offer very high suction at relatively low pressure.
These pumps are particularly suited to machining where there is a high level of air leakage and for large workpieces.
Centrifugal blowers provide more suction volume than side channel blower. But the downside is that the pressure is very low.
Compressed air powered vacuum generators which work on the 'Venturi Principle' offer a price advantage over a dedicated vacuum pump for customers who don't have a high usage requirement.
However if you plan to use it for long periods day in and day out it makes more financial sense to invest in a dedicated Vacuum pump.
