Industrial Equipment Solutions for the Food and Beverage Industry
The Food and Beverage Industry Landscape
Proper ingredient transfer equipment is crucial in the food and beverage industry. Manufacturers focus on maintaining optimal efficiency, high product quality, and balancing operating costs. When selecting equipment, organizations focus on several critical factors. These include flow rate and fluid characteristics (e.g., viscosity, temperature, abrasion, shear, and particle size).
Additionally, equipment material compatibility is also necessary to ensure safety and reliability:
Services such as CIP (clean-in-place), COP (clean-out-of-place), SIP (steam-in-place)
Process cleanability and batch or continuous operational concerns
Conformance to industry regulating entities such as the FDA, USDA/3-A, and EHEDG
All these factors are essential to equipment selection.
Moreover, the prevention of product contamination is crucial. A current challenge involves maintaining the separation between the pumped product and the mechanical elements driving the compression stage(s). To aid in this, organizations select pumps, valves, and lubricants based on:
The degree of hygiene required
Compliance with these standards
Process cleaning methods and their associated costs,
Organizations also use special mechanical seals, diaphragms, air gaps, and other types of systems to prevent compromising products. The purpose of these separator systems is to prevent contact between the hydraulic oil used to lubricate the pump and the food product chamber. Plus, these steps help to maintain product integrity. Product handling can affect texture, taste, and appearance. Some fluids need shear to get them to a viscosity where they can transfer, whereas others can become damaged due to shearing.
Compliance with Health Standards
For all equipment utilized in the food and beverage industry, FDA-approved materials are essential for wetted components, elastomers, and lubricants. Beyond this requirement, more stringent standards such as sanitary, 3-A, 3-A-SS1, USDA, and EHEDG may be applicable.
For FDA compliance, all components must comply with the CFR (Code of Federal Regulations) Title 21, Part 177. All components must satisfy the guidelines for safe, direct contact with food (food-grade), and the material must be able to withstand environmental conditions. Another certification commonly cited is NSF. This relates to water treatment and establishes stringent requirements for all equipment in contact with potable water from its source to tap.

Warren Rupp and Yamada Use Compressed Air
Warren Rupp uses compressed air to transfer a known volume of liquid from point A to point B. Due to the variety of materials available and their inherent operating characteristics, there aren’t many liquids that can’t be pumped with an air operated double diaphragm pump.
Yamada offers FDA-compliant passivation and clamp fittings as available options. AODD pumps offer run dry capability, the ability to handle solids without damage to pump or product, self-priming, and the ability to dead-head safely. They will also not shear or separate products, are submersible, are sealless for ease of maintenance, operate batch/intermittent or continuous duty, and provide various porting options.
Pulsatron offers NSF 61 for water treatment and disinfection services and Series A+, C(+), E(+), E-DC, MP, T7 metering pumps for pH control, acids/caustics, bleaches, catalyst, cleaning, and solvent applications.
While Mech-O-Matic metering pumps do not have approval for food and beverage processing, organizations use them for disinfection and sanitation services handling chemical solutions and slurries.
Finish-Thompson Centrifugal Pumps are FDA compliant and offer tri-clamp configurations. Polypropylene and PVDF constructions—which are FDA-approved—and various elastomers (e.g., kalrez, Teflon, viton, and EPDM) are standard options.
Many of Cornell's Centrifugal models are compliant with NSF 61, suitable for hot oil and wastewater services. The company specifically designed the Series P & PP (Hydro-Transport) pumps for the agriculture market to provide negligible damage to food products.
While the SPX Flow (CombiTherm and CombiTherm +) are not NSF- or FDA-compliant, the industry utilizes these centrifugal pumps with ovens, fryers, the distillation of fatty acids and glycerin services, fat softening, potato chips, and milk powder.
ITT Goulds and Gorman-Rupp
Numerous ITT Goulds (some models are NSF certified) and Gorman-Rupp pumps function in applications within food and beverage facilities—though not within the F&B process—offering reliability in ancillary services. These services include Condensate, Boiler Feed, Sump (overflow), Cooling water, Booster, Cooling Tower, and general transfer.
Estabrook also offers Chesterton products for sanitary and non-sanitary sealing applications. Chesterton provides products for sealing, lubricating, and metal coating to enhance the efficiency and reliability of food processing equipment.
Chesterton mechanical seals that meet NSF/ANSI 61 are Type 150, 155, and 180 single cartridge seals, as well as Type 442C and 442PR cartridge split seals. Chesterton also offers NSF H1 & H2 bearing lubricants to improve the bearing reliability in the harsh conditions of load, temperature, water, and corrosion which challenge the food and beverage industry. Chesterton also offers NSF industrial lubricants for chain drives, gears, belts, and rollers. Additionally, the company offers penetrating oil, anti-seize, gaskets/tape, corrosion inhibitors, cleaners, and degreasers to maintain plant equipment.
To increase mean time between failures (MTBF) and assist in reducing costly downtime due to premature bearing failure, Chesterton offers LUBRI-CUP, an automatic lubrication dispenser, which provides a precise amount of lubrication at specific intervals to avoid under- and over-lubrication of bearings.
