    <product_content><![CDATA[## ZRS 250-4200 Series from Atlas Copco The ZRS mechanical booster pumps, based on the simple roots principle, remains the favourite pump for applications where high pumping speeds are required for pressures in the region of 0.01 to 50 mbar. This pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure. Operating at relatively low pressures, the mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable. ## The ZRS Mechanical Booster pump is ideally suited for: Vacuum packaging Drying and de-gassing Vacuum metallurgy Vacuum distillation Thin film coating Low density wind tunnels Space simulation Vacuum impregnation Freeze drying Simple and trusted design ZRS booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor to the pumping mechanism. No pressure sensors, by-pass lines or valves Quicker pump-down times The hydrokinetic drive allows the booster pump to be started at the same time as the backing pump as it prevents motor overload, assisting the pumping process from the start of pump-down Automatic overload protection The hydrokinetic drive automatically varies the rotational speed of the pump, protecting the motor from overload and preventing over-heating. This allows the pump to operate with high-pressure differentials Cost savings Save money on installation and operation as capital costs are reduced because you do not need valves, by-pass lines and pressure switches ## ZRS series - Designed to boost your production • Suitable for applications where high pumping speeds are required in the pressure region of 0.01 to 50 mbar/0.0075 to 37.5 Torr. • Operating at relatively low pressures makes it highly reliable.• The ZRS pumps have a high quality, oil-free pumping mechanism. This offers:• Quiet, vibration free operation.• Rugged and corrosion resistant.• Advanced shaft-seal technology with no oil contamination of the process chamber.• The proven shaft-seal arrangement ensures that no oil enters the pumping stator, and the absence of internal and external by-pass lines and valves which may corrode or stick minimizes maintenance requirements. • The design of the shaft seals is optimized to ensure that no lubricants can migrate into the pumping mechanism. This maintains booster pump performance in applications which demand the highest standard of cleanliness. In addition, this prevents the build-up of trapped particles on the rotor lobes and end-faces which have very close tolerances. • The dynamically balanced rotors and precision ground gears contribute to the smooth, quiet operation of the pumps, as demanded by manufacturers of advanced technology equipment. ##]]></product_content>

    <product_content><![CDATA[## 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. ## Applications 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.• Li-ion battery production • Food and vegetable vacuum cooling • Vacuum drying • Freeze-drying • High speed packaging • Altitude simulation • Leak testing • Metallurgy degassing • Coating • Semi-conductor crystal growth or pulling ## ## 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 design 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 maintain 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 installation 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. Energy efficient pumps 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.]]></product_content>
