2-stage oil-sealed rotary vane vacuum pumps (GVD 40-275)
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.
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.
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.
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.
The GVD 0.7-28 series of small oil-sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation. With over 200,000 units sold, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. The GVD 40-275 series 2-stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapor. These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection. A comprehensive range of accessories is available to allow use on the widest variety of vacuum applications. You can rely on our GVD 2-stage oil-sealed rotary vane pump to deliver excellent ultimate vacuum pressure. It also has a high pumping speed and handles vapor efficiently, all the while operating quietly. Apart from the fact that its quiet it also has a fast acting anti suck back system protection, which ensures efficiency. A high torque, 1-phase and 3-phase multi-voltage and 50/60 Hz motors available make it flexible.
Renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapor, the GVD series 2-stage oil-sealed direct drive rotary vane pumps are inherently compact and vibration free.
