CinchSeal

What CinchSeal does

CinchSeal, Inc. is a privately held US manufacturer, founded in 1994 and headquartered in Cherry Hill, New Jersey, that designs and sells self-adjusting rotary shaft seals for industrial bulk-solids handling equipment — principally CEMA screw conveyors, ribbon blenders, paddle mixers, bucket elevators, and rotary airlock valves. Its core technology is a patented family of seals that spin with the shaft (rather than remaining stationary like conventional lip or packing seals), use air-purged PTFE rotor cups combined with FDA-approved silicone elastomer boots, and are offered in solid and split configurations across the 7500, 7600, 7800, and 9700 series in aluminum or 316 stainless steel. Hard-coated anodized aluminum rotor cups (Rockwell 62) support abrasive applications, and specialty variants include an Airless Rotary Face Seal, a High Speed Chopper Seal (up to 3,600 rpm), Poly Split CEMA seals, and Cartridge Seals.

The company sells to food processing (its primary vertical, covering baking, beverage, chocolate, dairy, meat and poultry, pet food, infant formula, and ethanol), as well as chemicals, pharmaceuticals, cement and gypsum, lithium-ion battery slurry mixing, gold and mining, pulp and paper, vitamin and supplement manufacturing, wastewater treatment, and industrial metal and aggregate handling. Named customers include Cargill, Nestle, Mars, Kraft Heinz, Mondelez International, Hershey, Tyson Foods, and BASF, and the company states it serves roughly two-thirds of the world's top food processing companies. Pricing is quote-based and custom-tailored to shaft diameter, bearing type, housing material, and application; revenue is generated through new seal sales, repair kits (typically priced at one-third of a new seal), and a refurbishment/repair service with 1- to 14-business-day turnaround. Distribution is hybrid: direct sales via website quote requests and a dedicated partner portal, a US and international independent representative network, and major industrial distribution houses (Motion Industries, Applied Industrial, Kaman Industrial Technologies); in 2025 the company added a distribution partnership with Advanced Sealing Technology (AST) to sell mechanical seals for high-speed ANSI pumps. Regulatory approvals include USDA Dairy, USDA Meat and Poultry, FDA approvals on silicone and PTFE components, EU Regulation (EC) No. 1935/2004, ATEX II 2 D, and 3-A Sanitary Standards.

Core offering

CinchSeal designs and manufactures self-adjusting, maintenance-free rotary shaft seals used on CEMA screw conveyors, ribbon blenders, mixers, and other bulk-solids handling equipment. Its product line spans the 7500, 7600, 7800, and 9700 series in aluminum or stainless steel, plus specialty seals (airless face, high-speed chopper, poly split, cartridge), repair kits, and—through an AST partnership—mechanical seals for high-RPM ANSI pumps. The company also offers factory refurbish and repair services for mechanical and rotary shaft seals.

Product overview

CinchSeal is a rotary shaft seal manufacturer offering a comprehensive portfolio of sealing solutions for industrial processing equipment. The product lineup includes multiple seal series (7500, 7600, 7800, 9700) differentiated by size capacity, material (aluminum, stainless steel), and configuration (solid vs. split). Specialty variants include Airless Rotary Face Seals, High Speed Chopper Seals, Poly Split CEMA Seals, and Cartridge Seals for specific applications. The company also offers a complete accessory line including repair kits and air regulator/gauge kits. Through a partnership with Advanced Sealing Technology (AST), CinchSeal distributes mechanical seals for ANSI pumps including the AST 50, 60, 70, and 80 series. Additional services include mechanical seal refurbish and repair with quick turnaround. All seals are designed for screw conveyors, mixers, blenders, bucket elevators, and other bulk handling equipment across food, pharmaceutical, chemical, and industrial applications.
