Atlas Copco DRB VSD+ and DRB booster pumps
DRB VSD+ and DRB booster pumps from Atlas Copco
Booster vacuum pumps, also known as Roots vacuum pumps, are generally used to increase the pumping speed of a system or with the goal of reaching a lower ultimate vacuum level. Booster pumps are used in a wide range of applications, most used in the rough vacuum range, especially when high pumping speeds and low pressures are required. Combined with dry or oil-sealed fore-vacuum pumps, our DRB and DRB VSD+ range of booster pumps are used very effectively to increase the pumping speed at low pressures, thus extending the operating pressure range of the fore-vacuum pumps. Due to the non-contact rotational design of these pumps, they are able to run at higher speeds, offering increased pumping speeds for the backing pumps. An added advantage is the lower energy consumption as compared to a single backing pump with the same pumping speed.
Booster pumps are used in a wide range of applications, most commonly used in the rough vacuum range, especially when high pumping speeds and low pressures are required.

Booster pumps combined with VSD technology
The most frequent use of the DRB Roots vacuum pumps is as an enabler for smaller primary vacuum pumps. They are designed to boost the most demanding requirements for modern vacuum-based production processes. We have taken this a step further and combined it with Atlas Copco Vacuum’s Variable Speed Drive (VSD) technology.
Simple and trusted
The DRB series, non-contact rotational design offers increased pumping speeds for backing pumps. Smart design features include protection against thermal overloading. The DRB VSD+ and DRB series are available in air-cooled versions
Robust and easy to
The robust pump design boosts the most demanding process requirements for industrial applications. Service intervals are longer and requires minimal on-site maintenance.
Easy and flexible
The DRB VSD+ and DRB series of pumps can be easily connected to any primary vacuum pump. They are easy to integrate into existing vacuum systems due to their compact design. It is also easy to implement conversion from vertical to horizontal flow.
The DRB VSD+ and DRB series of booster pumps are equipped with IE3 three-phase motors and consume lesser energy and have low carbon emissions and noise levels.
