We advise to use a side channel pump in combination with a vacuum table, when there is a lot of leakage. For example when milling porous materials like MDF. Or when milling through the material. It is always very important to look at the Pressure VS Flow curves when comparing to other pumps. We use a Dual Rotor pump which has less flow, but more under pressure. For a vacuum table the combination of under pressure and flow is important, since there is often leakage. This pump is a good choice when milling porous materials with a lot of leakage, and also for large surface areas. When needing to clamp small parts (smaller than 100x100mm) we advise to use a Rotary Vane Vacuum pump, it has much less flow but higher under pressure. Another tip. If possible always use a VFD in combination with the pump. You need a soft starter anyway. And the VFD does 2 things, one it works as a soft starter, to prevent your fuses blowing. Two it increase the performance of the pump dramatically. Going from 50 to 60hertz you can see in the curve at the same under pressure the flow is factor 2 times higher.
