PM 5986 Liquid Ring Vacuum Pumps & Compressors

Our replacement liquid ring vacuum pumps and compressors are engineered for rugged, continuous industrial duty — providing reliable performance in wet-gas, vapor-laden, and condensate-carry environments. Designed to be fully compatible with the Somarakis® SV-series and HV-series models, they offer seamless interchangeability while delivering enhanced serviceability, sourcing transparency, and competitive value.

• Broad capacity range: from approximately 80 to 28,000 CFM (free dry air), and vacuum performance down to 1.0-2.0″ HgV up to flows of 28,000 CFM. 
• Compressor mode capability: up to ~50 PSIG discharge for compression service. 
• Material options including Cast Iron, Stainless Steel 304, Stainless Steel 316L, Titanium, and Hastelloy — suited for corrosive or sour-service applications. 
• Single-moving-part design (eccentric rotor + liquid ring) with no metal-to-metal sliding contact, for high reliability in demanding service. 
• Patented sealing / bearing innovations (e.g., design features such as seal water recirculation and secondary bearing support) that enhance durability and reduce downtime. 
• Full test-certified performance curves and individually tested units — ensuring you get consistent results verified at factory. 

• Interchangeability: Drop-in replacement for existing Somarakis® SV/HV units — same mounting patterns, same porting, simplifying retrofit or upgrade projects.
• Wet-gas and liquid-carry handling: The liquid ring design tolerates entrained condensate, vapour, and two-phase flows — ideal for storage tank vapour recovery, refinery flare gas systems, vacuum distillation, and other heavy-duty applications.
• Material flexibility: For sour-gas, H₂S environments, or corrosive vapour streams, select from a full alloy portfolio ensuring compliance and long service life.
• After-market support: We guarantee OEM-level parts and service availability — with options for rebuild/refurbish programs or new build units depending on budget and schedule.
• Cost-effective value: Because we leverage our manufacturing base and a streamlined supply chain, we deliver competitive pricing with full documentation and traceability.

• Oil & gas mid-stream vapor-recovery units (VRUs) and storage-tank vent systems
• Refinery vacuum distillation, absorber systems, and flare-gas recovery
• Chemical and petrochemical vacuum or compression service with wet or vapour-laden streams
• Pulp & paper dewatering, power-plant condenser vacuum systems, and environmental/vapour extraction processes
• Food, beverage, pharmaceutical vacuum drying or packaging systems where liquid carryover is present

• Flow capacity of 80 to 28,000 CFM (free dry air) 
• Vacuum levels down to ~1.0-2.0″ HgV (depending on size/model) 
• Compression discharge Up to ~50 PSIG discharge for compressor mode 
• Material optionsCast Iron, SS 304, SS 316L, Titanium, Hastelloy

1. Provide your current pump nameplate or model (for example Somarakis® SV-1414, SV-1818, SV-5986, HV-7, etc.).
2. Send us your process conditions: vacuum level, discharge pressure (if compressor mode), gas composition (presence of H₂S or corrosives), entrained liquid load, sealing fluid condition, motor horsepower.
3. We will propose a compatible replacement or upgrade that maintains your system’s footprint, utilities, and interface, with a quote showing the cost, lead time, and material spec.
4. Optional: we offer on-site install support, start-up assistance, and service contracts for rebuilds or ongoing maintenance.
