Cromox Pump Chains
Cromox pump chains are stainless steel chains designed for pump suspension and below-grade lifting in corrosive environments. Where a carbon steel chain would corrode in a matter of months, in a chemical sump, a water treatment pump station, or a marine bilge, a Cromox stainless chain stays in service. Holloway Houston stocks Cromox pump chains from our Houston warehouse and ships nationwide.
Cromox Stainless Steel Pump Chains
Pump chains are used to suspend, lower, and retrieve submersible pumps, mixers, and below-grade equipment from sumps, wet wells, pits, and underground chambers. The chain hangs in place and stays in the liquid or vapor environment indefinitely, which is exactly why material selection matters.
Cromox pump chains are manufactured from stainless steel by the pewag Group in Austria. Stainless steel resists the corrosion that attacks carbon chain in wet, chemical, and saline environments. A carbon chain in a sewage wet well or chemical sump will corrode and eventually become a safety concern. Stainless holds up far longer under continuous exposure.
The Cromox line is part of the pewag Group's stainless hardware range, which holds ISO 9001 certification. Chains meet the EN standard applicable to the grade and size.
Pump Chain Applications
Water and Wastewater Treatment
Submersible pump chains in lift stations, wet wells, and treatment basins hang continuously in water and sewage. Carbon chain corrodes in these environments. Stainless steel is the industry standard for pump chain in municipal and industrial water systems.
Chemical Processing
Sump pumps, mixers, and agitators in chemical plants hang from chains exposed to chemical splash, vapor, and immersion. The specific chemical resistance of stainless steel depends on the chemical, but for most common industrial acids, caustics, and process chemicals, stainless outperforms carbon steel significantly.
Marine and Offshore
Bilge pumps, saltwater cooling pumps, and ballast pumps on vessels need chains that tolerate saltwater. Stainless resists marine corrosion where carbon chain corrodes quickly.
Food Processing and Beverage
Pumps and mixers in food plants run in washdown environments with cleaning chemicals. Stainless pump chain is the choice wherever FDA-compliant or USDA-compliant materials are specified.
Offshore Platforms
Offshore pump systems operate in sea air and saltwater spray environments. Stainless pump chains are standard for offshore pump suspension.

Why Holloway Houston for Cromox
Holloway Houston has served the rigging and lifting industry from Houston for over 65 years. We stock Cromox stainless steel hardware because Gulf Coast industrial operations, refinery, petrochemical, offshore, and marine, run into corrosion problems regularly. Stainless hardware is not a specialty item here; it is a day-to-day inventory requirement.
Holloway Houston also provides rigging inspection services. Our inspectors examine chains and hardware per applicable ASME standards.
Pump Chain Safety and Awareness
Pump chains are load-bearing components subject to inspection requirements under applicable OSHA and ASME standards. Key awareness points:
- Stainless steel pump chains are inspected on the same basis as carbon chain, visual inspection for cracks, deformation, link distortion, and corrosion.
- Chain markings, manufacturer identification, and WLL ratings are part of the product documentation. Chains without legible identification are removed from service.
- Continuous immersion in chemicals may affect chain properties over time. Replace chain on a schedule based on the operating environment and manufacturer guidance.
- Proof test documentation is available through Holloway Houston with purchase.

Frequently Asked Questions
Cromox pump chains are stainless steel chains used to suspend and retrieve submersible pumps, mixers, and below-grade equipment from sumps, wet wells, pump stations, and other submerged or chemically exposed locations. The stainless steel material resists the corrosion that affects carbon steel chain in these environments.
Carbon steel chain corrodes in wet, chemical, and saline environments. A carbon chain hanging in a sewage wet well, chemical sump, or marine bilge will corrode over time, degrading the chain's condition and creating a maintenance concern. Stainless steel holds up under continuous exposure far better than carbon steel.
Cromox pump chains are used in water and wastewater treatment, chemical processing, marine and offshore, food and beverage processing, and pharmaceutical manufacturing. Any environment where a pump or mixer hangs in corrosive conditions is a candidate for stainless chain.
Cromox pump chains are manufactured by the pewag Group under EN standards applicable to the chain's grade and size. The pewag Group is ISO 9001 certified. For exact grade and standard designations, request the Cromox product data sheet from Holloway Houston .
