Simplifying vacuum pump specs for assembly needs

Specifying vacuum pumps to lift a particular component in an assembly operation is something of a black art. This variable vacuum pump affords a practical solution to this problem.
Specifying vacuum pumps to lift a particular component in an assembly operation is something of a black art.
This variable vacuum pump affords a practical solution to this problem.
Specifying air-driven vacuum pumps can give design engineers a few sleepless nights.
Although theoretical vacuum calculations are relatively simple, in practice, correctly specified products can refuse to perform - leaving the designer somewhat perplexed.
The reasons for performance deviations lie in variations in the application dynamics; relative porosity of the material being transported may vary.
air pressure may alter within specific windows of the machine cycle, etc.
These factors make accurate pump selection somewhat difficult.
But now, KV has come up with a practical solution.
Their new Variable Vacuum Pump - designated KVDF- provides a functional solution to vacuum application problems.
With the new unit, vacuum flow can be infinitely varied (between 115 and 3400 normal litres/min) by simple rotation of the two-piece body.
Once the desired set position is reached, the unit is locked by an annular locking-ring.
At this point, the unit can be permanently mounted to the machine or (providing vacuum flow levels have been recorded) replaced by a unit of fixed performance.
