2020 Atlas Copco GLS 250-500 Series 250/ZRS 500

With an efficient space saving design, excellent performance and reliability, our GLS rotary piston pump is synonymous with efficiency and dependability.

Features may include:

• Thanks to the slow rotational speed, reliability is optimum and lifecycle cost is low.

• Lubrication of the internal components of the pumps is completely automatic. This pump is fitted with a 230/460 V coil for control of the oil solenoid valve which prevents the pump from flooding with oil in case of a power failure or loss of vacuum.

• All GLS pumps are fitted with a water mizer to minimize the water consumption and optimize the running temperature. This brings extra reliability, a longer period between maintenance and a very low lifecycle cost.

• To allow pumping of high vapor loads, integral gas ballast is fitted. This is used to prevent condensation of the vapor carried by the pump gases.

• With over 10,000 units sold in 80 years, the Atlas Copco GLS rotary piston pump sets the standard for performance and reliability as the industry’s most efficient, space-saving design.

• As part of the Atlas Copco Group, Stokes Vacuum continues to innovate oil-lubricated rotary piston pumps. The GLS has been improved, upgraded and fine-tuned.

• It delivers even better dependability and productivity combined with minimal maintenance and process downtime, especially crucial in demanding applications such as the automotive or aerospace industry and their supply chains.

• Designed compactly for maximum uptime with minimal moving parts and large clearance, the GLS rotary piston pump has advanced balancing that reduces vibration and is easy to maintain. Add a ZRS booster to the GLS to increase the pumping speed.

• Every feature works towards providing you with exactly what you need. From a low lifecycle cost, to in-house service for extra peace of mind, to reliable operation.

• Keeping in mind the automotive and aerospace industry and their supply chains, the GLS has been improved, upgraded and fine-tuned.
