NASH liquid ring vacuum pumps are known as tireless workhorses, designed to stand up to the rigorous, nonstop demands of harsh industrial environments. Built better than industry standards, NASH liquid ring two stage vacuum pumps have been known for their reliability.
Our liquid ring two stage vacuum pumps provide reliable, high vacuum performance with capacity ranging from 400 to 2,800 ACFM (680 to 4,750 m³/hr) and can reach vacuum levels down to 0.8 in HgA (30 mbar abs), which is approximately 40% lower absolute pressure than a single stage pump.
Liquid ring two stage vacuum pumps are designed to handle large amounts of liquid carryover without difficulty and with their integral two stage rotors for the TC product line, liquid ring two stage vacuum pumps are able to condense vapors that come off the process and to recover or dispose of them. These pumps are rugged and long-lasting machines ideal for harsh and demanding industrial environments such as chemical, petrochemical, and power industries.
Condenser Exhauster With Liquid Ring Two Stage Vacuum Pump
NASH condenser exhausters have been the products of choice for air removal systems in steam cycle power plants throughout the world. Decades of experience have led to the NASH system. These systems are pre-engineered for quick delivery and installation, consisting of a two stage liquid ring vacuum pump, air-liquid discharge separator, heat exchanger and associated controls.
Reliably Handles Large Volumes At Deep Vacuum Levels
NASH liquid ring two stage vacuum pumps can be combined with ejectors or boosters to form hybrid packages. NASH hybrid vacuum systems or steam and air jet ejectors are engineered for optimum efficiency while maintaining their ability to handle large volumes at very high vacuum levels. With no moving parts, steam and air ejectors deliver reliable performance, simple operation with a low capital cost.
Further benefits of ejectors & hybrid systems include:
Low capital investment
Customizable system configuration that reduces greenhouse gas emissions and steam consumption
Reliable & Efficient With Proven Performance
Nash liquid ring two stage vacuum pumps offer superior performance and reliability through the proven reliable conical liquid ring pump design with rotor blades that are shrouded to improve strength and reliability.
Conical Porting & Rotor Configuration
NASH’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, NASH’s patented design features:
Option for lobe purge to minimize damage from erosion in duties with solids present
Large differential pressure capability
Gas scavenging feature minimizes slip of gas from discharge to inlet improving capacity, especially at deep vacuum
High liquid carryover tolerance
Side discharge to minimize the chance of flooded start
Self-priming design may allow the elimination of booster pump in recirculated systems
