What Vooner FloGard Corporation does

Vooner FloGard Corporation, operating as Vooner FloGard LLC since its January 2022 acquisition by Aerzen USA, manufactures liquid ring vacuum pumps, compressors, and paper machine dewatering equipment for industrial customers in the paper, power generation, food processing, mining, and chemical processing sectors. Headquartered in Fort Mill, South Carolina with manufacturing operations in a 54,000 sq. ft. facility in Greeneville, Tennessee, the company has supplied vacuum systems globally since 1983. Its core technology centers on liquid ring vacuum pump architecture featuring a single moving part (impeller) with no metal-to-metal contact, and is differentiated by patented cone port designs that allow passage of process liquids, condensates, and entrained solids while maintaining vacuum efficiency. The product portfolio includes the Vooner FloGard V-series pumps, VaneGard series (with patented dual water supply and removable bearing carriers since 1994), two-stage VTS pumps, and — following the Aerzen integration — dry claw, dry screw, diaphragm, and wet rotary vane pumps (EM and EU HWT Series) plus Aerzen high vacuum boosters.

The company operates a B2B enterprise field sales model targeting paper mills, power plants, food processing facilities, mining operations, and chemical plants, selling quote-based custom-engineered equipment through named contacts including VP of Business Development and Customer Service. Revenue is generated through three streams: hardware sales of vacuum pumps, compressors, and engineered dewatering components; aftermarket parts and accessories; and professional services including in-house actuator repair programs (covering Shenandoah, Dolphin, ROLLTECH, and General Morgan brands with 12-month warranty), on-site orifice testing with written performance survey reports, and technical consulting for system sizing and pump selection. Pricing is quote-driven with multi-year contract cadences for capital equipment and pay-as-you-go for service work; pricing has never been publicly disclosed. Pulp and paper is the primary vertical, with the firm participating annually in TAPPI exhibitions since 1986 and aligning sizing methodology to TAPPI TIPs recommendations.

Broad incumbents

• Edwards Vacuum (Atlas Copco): Edwards Vacuum, owned by Atlas Copco, is a large vacuum pump manufacturer focused on dry pumps, turbomolecular pumps, and leak detection for semiconductor, R&D, and industrial markets. It competes with Vooner's industrial vacuum and high-vacuum booster lines for industrial and emerging electronics/pharma customers.
• Kaeser Compressors: Kaeser is a global manufacturer of compressors and vacuum blowers serving industrial, food/beverage, and packaging end markets. Its rotary screw compressors and vacuum blowers compete with Vooner's high-vacuum booster and compressor product lines (GC-GV, CD series) in industrial compressed-air and vacuum applications.
• Ingersoll Rand: Ingersoll Rand's Industrial segment produces compressors, blowers, and vacuum pumps serving power, paper, chemical, and mining end markets. Its broader product portfolio and global service footprint make it a benchmark incumbent against which Vooner's specialty liquid ring offerings are positioned.
• Atlas Copco: Atlas Copco is a global industrial group with extensive compressor and vacuum pump portfolios (including Nash, Edwards, and Gardner Denver integrations). It competes broadly across nearly all of Vooner's verticals and is the parent of the company's most direct competitor (Nash).
• Pfeiffer Vacuum: Pfeiffer Vacuum (part of Busch Group) offers a broad portfolio including rotary vane, turbo, and dry pumps targeting laboratories, semiconductors, pharmaceuticals, and industrial vacuum — adjacent to Vooner's industrial liquid ring offerings and overlapping with several of the new verticals opened via PVR.

Direct peers

• Busch Vacuum Solutions: Busch is a global manufacturer of vacuum pumps (liquid ring, rotary vane, dry claw, screw) with deep penetration in chemical, food, plastics, and packaging — overlapping Vooner's wet rotary vane (EM/EU series) and industrial vacuum pump lines and the verticals opened by the PVR partnership.
• Nash (Atlas Copco): Nash, now part of Atlas Copco, is the historical leader in liquid ring vacuum pumps and compressors, with overlapping product families used in pulp & paper, chemical, and power. Vooner even acquired CVN Systems from Nash in 2003, illustrating direct product-line competition and shared customer base.
• Dekker Vacuum Technologies: Dekker manufactures liquid ring vacuum pumps and compressors with comparable capacity ranges (ACFM) and similar industrial applications. It competes directly with Vooner's V-series, VaneGard, and VTS liquid ring product families across paper, chemical, and power customers.
• Tuthill Corporation: Tuthill manufactures industrial pumps, vacuum pumps, and blower systems, including liquid ring and rotary vane designs for similar industrial end markets. Its product breadth and direct engineering sales model mirror Vooner's approach in pulp & paper and chemical processing.
• Sterling SIHI (Sundyne): Sterling SIHI, now under Sundyne, is a long-established liquid ring pump and compressor manufacturer serving chemical, petrochemical, paper, and power markets. Its product portfolio (single-stage, two-stage liquid ring pumps, dry vacuum pumps) overlaps Vooner's offerings in both technology and target industries.
