GROCO

GROCO (Gross Mechanical Laboratories) is a family-owned American manufacturer that has been a staple in the marine industry since 1918. They are best known for their high-quality raw water strainers, marine toilets, and bronze valves, all engineered to withstand the rigors of the saltwater environment.

Raw Water Strainers

GROCO strainers are the first line of defense for your engine, generator, and air conditioning systems, preventing debris from entering and causing damage.

• The GROCO ARG Series Strainer is a favorite among boaters for its "one-piece" sight glass design, which eliminates many of the leak points found in multi-part strainers. It features a 304 stainless steel basket and a durable bronze base.

• For high-speed applications, the GROCO AHS Series includes an integrated high-speed scoop to ensure consistent water flow even when the boat is traveling at peak velocities.

Marine Sanitation & Water Systems

GROCO offers robust, reliable toilets and pumps that are designed to be easily serviced rather than replaced.

• The GROCO K-H Series Manual Toilet is famous for its powerful pump stroke and "large bowl" comfort. It is built with a bronze pump house for extreme longevity.

• The GROCO Paragon Senior Water Pressure Pump is a heavy-duty DC pump capable of supporting multiple outlets simultaneously, providing "house-like" water pressure for larger yachts and commercial vessels.

Key Performance Advantages

• Serviceability: GROCO products are designed with replaceable parts (gaskets, baskets, and seals), ensuring you don't have to replace the entire unit if a single component wears out.

• Bronze Construction: Unlike plastic or lightweight alloys, GROCO uses 85-5-5-5 bronze, which is highly resistant to dezincification and corrosion.

• Made in the USA: Most of their core casting and assembly takes place in Maryland, ensuring top-tier quality control.
