ATEX-Certified Liquid Ring Vacuum Pumps and Compressors

The ATEX Directive (Atmosphères Explosibles) establishes the requirements for equipment used in potentially explosive atmospheres. ATEX classifications define the risk level in specific zones:

• Zone 0: An area in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor, or mist is present continuously, for long periods, or frequently.
• Zone 1: An area where explosive atmospheres are likely to occur during normal operation.
• Zone 2: An area where explosive atmospheres are unlikely, but possible, and occur infrequently or for short durations.

NASH pumps are meticulously designed to comply with these classifications, delivering safety and reliability for operations in Zones 0, 1, and 2.

Reliable, Safe, and Efficient Solutions for Hazardous Environments

At Nash, we understand the challenges of operating in potentially explosive environments. Our ATEX-certified liquid ring vacuum pumps and compressors are engineered to provide unparalleled safety, reliability, and performance, ensuring your processes run smoothly while meeting the strict requirements of ATEX zones.

Our liquid ring vacuum pumps and compressors are trusted worldwide for critical applications in industries such as oil & gas and chemical processing. Here’s why NASH products are the preferred choice:

1. Guaranteed Safety in Explosive Atmospheres
2. Reliable and Maintenance-Friendly
3. Application Versatility

Our ATEX-certified pumps excel in a range of demanding applications:

• Flare Gas Recovery: Improve efficiency and reduce emissions with safe gas handling.
• Chemical Processing: Safely compress and recover volatile organic compounds (VOCs).
• Oil & Gas Recovery: Ensure smooth operations in refineries and petrochemical plants.

Understanding temperature classifications and gas groups is essential for selecting the right ATEX-certified liquid ring vacuum pumps and compressors for hazardous environments.

Temperature Classes (T1-T6)

The ATEX directive defines temperature classes based on the maximum surface temperature of equipment, ensuring safe operation without igniting surrounding explosive gases.

Gas Groups (IIA, IIB, IIC)

Explosive gases are categorized into groups based on their ignition properties, particularly their minimum ignition energy and flame propagation characteristics.

1. Safe Handling of Wet and Flammable Gases
   1. NASH pumps maintain peak performance even with liquid carryover, eliminating the risk of failure common in dry-running systems.
2. Low Maintenance, High Efficiency
   1. Our pumps are engineered for continuous, uninterrupted operation, with minimal servicing required, even under heavy-duty conditions.
3. Environmentally Responsible Solutions
   1. Our technology supports processes like flare gas recovery, reducing emissions and meeting sustainability goals.
4. Customized for Your Needs
   1. We offer engineered-to-order (ETO) solutions to meet specific ATEX requirements, ensuring seamless integration into your system.

• Pulsation-Free Operation: Ensures smooth and continuous flow without pressure fluctuations, enhancing process stability.
• Nearly Isothermal Compression: The compression process involves minimal temperature change, reducing the risk of ignition in hazardous environments.
• Built for Non-Stop Operation: Engineered for continuous, uninterrupted service, these pumps are ideal for demanding industrial applications.
• No Metal-to-Metal Contact: The design eliminates internal metal-to-metal contact, reducing wear and extending equipment lifespan.
• Oil-Free Compression: Provides clean compression no contamination of process gas, ensuring the purity of the process gas and reducing maintenance requirements.
• Pressure Control by Bypass and/or VFD: Offers precise pressure regulation through bypass systems or variable frequency drives (VFDs), allowing for adaptable and efficient operation tailored to specific process needs.

With decades of experience and a commitment to innovation, NASH ATEX-compliant pumps are trusted by customers around the world to deliver safety, performance, and peace of mind.
