Easy maintenance

Advanced lubrication system allows the pump to work with wide oil level tolerances, which reduce the need to top-up the oil. Constructed with internal dowels, reducing the need for skilled setting of tolerances and all key components are designed to be easily accessible.

Positive pressure oil lubrication

Incorporate well proven positive pressure oil lubrication system ensuring correct lubrication to prevent oil starvation with high gas loads.

Designed for reliability

When the pump is switched off, the spring-loaded distributor valve provides oil and air suck-back protection. Industrial roller bearings on drive shaft for ultimate reliability and long, trouble free life.

Built for your needs

The pumps and accessories can be supplied either as individual components or as fully systemized, factory tested combinations. Easy to maintain, with convenient service kits and international customer support.

GVD series - Two-stage oil-sealed rotary vane vacuum pumps

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.

Efficient vacuum solution

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.
