OIL-SEALED ROTARY VANE PUMPS

2-stage oil-sealed rotary vane vacuum pumps (GVD 40-275)

The GVD series of 2-stage oil sealed rotary vane vacuum pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation.

Silent and steady

We understand the need for quiet. With emphasis on the pump’s high performance and quiet running along with its intrusive frequencies minimized, this pump works with you.

Easy maintenance

The advanced lubrication system allows the pump to work with wide oil level tolerances, which reduce the need to top-up the oil. All GVD pumps are constructed with internal dowels, which reduce the need for skilled setting of tolerances, when the pump is dismantled. The pumps are designed so that all key components are easily accessible.

Positive pressure oil lubrication

The GVD pumps incorporate a well proven positive pressure oil lubrication system which has been developed to ensure correct lubrication in all duty modes and particularly to prevent oil starvation with high gas loads.

Consistent and reliable

No unpleasant surprises. Your back is always covered. Our pumps are reliable and simple, as each and every pump has protection devices to prevent oil and air suck-back into the vacuum system if the pump stops while under vacuum.
