What Vorti-siv does

Vorti-Siv, a division of MM Industries, Inc., is a US-based industrial equipment manufacturer specializing in gyratory sieves, vibrating screen separators, self-cleaning filtration systems, and replacement screens used for particle size separation and liquid filtration. The company was founded in 1968 by Rudolf Maroscher, P.E., and operates manufacturing facilities in Salem, Ohio (headquarters on the original 400-acre site) and Massillon, Ohio (Circular Screens Division, acquired in 2010). Its core technology centers on an off-balance flywheel-driven orbital screening action that prevents blinding, complemented by an SFA ultrasonic mesh de-blinding system capable of fine-mesh separation down to 20 microns. The product portfolio spans Lab (8-12 inch), Pilot (15-24 inch), and Production (up to 60 inch) screen diameters across RBF, RVM, VS, and Traditional series, plus blade-type self-cleaning filters and replacement screens compatible with SWECO, Kason, and Midwestern units.

The company sells custom-quoted equipment primarily through a network of regional US distributors (covering 10+ territories) and international channel partners across 9 countries, with no publicly disclosed pricing. Its customer base is concentrated in three regulated verticals: Food (Pepperidge Farm, Nestle, Kraft, General Mills, McCormick), Pharmaceutical and Nutraceutical (Merck, GSK, Perrigo, Allergan, Teva, Patheon, Dr. Reddy's, Abbott), and Powder Coatings (AkzoNobel, Sherwin-Williams, DuPont, PPG). Revenue is generated through capital equipment sales, custom engineering for specialized applications, and a recurring replacement screen business with 1-2 day lead times. Recent product extensions have addressed the 3D printing additive recovery and cannabis/hemp processing markets through integrations with Vac-U-Max pneumatic conveying equipment.

Vorti-Siv holds CE, FDA, and explosion-proof (XP NEMA 7-8-9) certifications on relevant models and operates as a privately held subsidiary of MM Industries, Inc. with 11-50 employees. The firm has not raised external funding, executes no digital or AI-based products, and pursues growth primarily through incremental product line extensions, distributor network expansion, and aftermarket replacement screen sales rather than platform or geographic reinvention.
