Western States Machine Company

What Western States Machine Company does

Western States Machine Company is a US-based industrial centrifuge manufacturer founded in 1917 by Eugene Roberts in Salt Lake City, Utah and currently headquartered in Fairfield, Ohio. The company designs, engineers, and manufactures vertical filtering and decanting centrifuges for solid-liquid separation across three principal vertical markets: sugar processing (more than 95 years of continuous service), chemical and pharmaceutical manufacturing (since 1950), and botanical/cannabis extraction (entered in 2017, formalized with the WSB-40 launch in 2019). Western States reports a global installed base of more than 6,000 centrifuges and notes that units from the 1950s remain in service, indicating long product lifecycles and a durable aftermarket footprint.

Direct peers

• Flottweg SE: German manufacturer specializing in decanter centrifuges, disk stack separators, and screw presses for chemical, pharma, food, and beverage applications. Direct competitor to Western States' chemical/pharmaceutical vertical filtering and decanting centrifuges, with comparable custom-engineering business model.
• Heinkel Filtering Systems: German specialist in vertical peeler and inverting filter centrifuges for chemical, pharmaceutical, and food applications. Direct competitor to Western States' Quadramatic and SLC-5000 product families, serving similar regulated manufacturing customers with engineered-to-order separations equipment.
• Tomoe Engineering Co., Ltd. Japanese manufacturer of industrial centrifuges (peeler, pusher, decanter) for chemical, pharmaceutical, food, and sugar processing. Closest Asian-market direct peer to Western States, with overlapping product types and end-user verticals including sugar refining.
• Broadbent Inc. UK-based manufacturer of industrial centrifuges (batch and continuous) for sugar, chemical, mineral, and pharmaceutical processing. Particularly strong overlap with Western States' sugar processing and continuous centrifuge (Roberts I-Series / Titan) portfolio, and serves many of the same Latin American and Caribbean sugar customers.
• Rousselet Robatel: French manufacturer of high-speed industrial centrifuges (peeler, basket, pusher) for pharmaceutical, chemical, and fine chemical applications. Particularly comparable to Western States' chemical/pharmaceutical product range including SLC and Quadramatic lines, with similar GMP and sanitary construction requirements.
• Siebtechnik Tema: European manufacturer of centrifuges and screening equipment for mining, chemical, pharmaceutical, and food applications. Comparable to Western States in offering specialized solid-liquid separation equipment with engineered-to-order configurations for similar end markets.
• ANDRITZ Separation: Austrian-headquartered manufacturer of separation equipment including screen bowl, pusher, and decanter centrifuges used heavily in sugar and chemical processing. Closest large-scale direct peer to Western States' sugar and chem/pharma centrifuge product lines, with overlapping customer base in cane/beet sugar refiners.

Broad incumbents

• Alfa Laval: Swedish multinational that is one of the world's largest manufacturers of separation equipment, including industrial centrifuges used in sugar, chemical, pharma, and food processing. Direct overlap with Western States' core product category, but operates at much larger scale and across a broader portfolio (heat exchangers, fluid handling, food equipment).
• GEA Group: German-based global leader in separation and centrifuge technology for dairy, food, beverage, chemical, and pharma industries. Directly comparable to Western States' vertical filtering and decanting centrifuge portfolio, but GEA serves far broader markets and runs significantly larger volumes.

Regional players

• B&P Littleford: U.S.-based manufacturer of mixing, drying, and separation equipment for chemical, pharmaceutical, and food industries. Comparable to Western States as an American-made specialty industrial equipment vendor, though more focused on mixers/reactors than centrifuges; useful as a comparable for parts/service economics in similar U.S. industrial customer base.
