DRB series
The DRB series non-contact rotational design offer increased pumping speeds for backing pumps. You are able to switch on at atmospheric pressure with the backing pump. Smart design features include an integrated by-pass and protection against thermal overloading.
The compact design of DRB pump means it is easy to integrate into existing vacuum systems. It is also easy to implement conversion from vertical to horizontal flow.
The robust pump design boosts the most demanding requirements for modern industry. Services intervals are longer and requires minimal, simple on-site maintenance.
The DRB series of pumps are equipped with IE3 three-phase motors and consumer lesser energy and have low carbon emissions and noise levels.
The DRB series of pumps are best suited to applications where rapid evacuations need to be achieved in the shortest possible cycle times. They are used in a wide range of applications especially when high pumping speeds and low pressures are required, from atmosphere to 1x10-3 mbar.
