The NASH P2620 Liquid Ring Vacuum Pump is a large-capacity, single-stage unit designed for demanding industrial vacuum applications where consistent performance and high throughput are critical.
Its robust construction and flexible configuration options allow it to be integrated into both new system designs and existing plant operations with minimal disruption.

Utilizing liquid ring technology, the pump maintains stable operation while handling saturated gases, vapors, and entrained liquids without internal damage.
Engineered for continuous-duty service, the P2620 delivers reliable vacuum performance across fluctuating process conditions. It is well suited for heavy industrial environments requiring dependable vacuum under challenging operating conditions.
Key Characteristics
- Suction Capacity: Up to approximately 20,000+ m³/h (capacity varies by configuration and operating conditions)
- Vacuum Range: Down to approximately 33 mbar abs. (1 inHgA), depending on service liquid temperature
- Design: Single-stage liquid ring with heavy-duty casing construction
- Shaft Seals: Mechanical seal or packing options available
- Materials of Construction: Typically cast iron with optional materials for corrosive environments
- Configuration Flexibility: Multiple porting and mounting arrangements for system integration
- Operation: Smooth, low-vibration performance with minimal internal wear
Ideal Applications
The P2620 is designed for high-volume vacuum requirements where durability and process tolerance are essential. Its ability to manage wet, dirty, or vapor-laden gas streams makes it a reliable solution in environments where other vacuum technologies may struggle.
