DWS 450-750 VSD+

Intelligent dry screw vacuum pump with an IP rated canopy and remote monitoring features

The vacuum pump is friendly on the environment – the dry screw operations of the DWS VSD⁺ mean there is no contaminated or dirty oil to dispose of lowering recurring maintenance costs significantly.

In addition to lower maintenance costs, you can expect significantly lower energy and utility costs. The Variable Speed Drive (VSD) technology built-in to the pump optimizes energy consumption leading to substantial energy savings. The robust and compact canopy offers your installation an economical footprint, saving you space on your production floor or in your vacuum utility room.

The DWS VSD+ series of dry screw vacuum pumps are ideally suited for
