Sherwood Pump Water Pump & Components

Sherwood Pump: A Century of Marine Water Pump Excellence

Sherwood Pump is one of the most storied names in marine engine cooling, and their Water Pump & Components lineup is the product of over a century of specialized engineering. Few brands can claim a heritage that stretches back to the early 1900s — yet Sherwood's roots in precision brass and copper manufacturing have directly shaped the quality and durability that marine technicians and boat owners depend on today.

Sherwood's origins trace to 1903, when William Sherwood and his business partner David Buick — later of General Motors fame — operated a copper brass plumbing business before parting ways. Sherwood channeled that metallurgical expertise into the marine world, and the results were transformative. Sherwood Pumps became a prime supplier of marine engine coolant pumps for the United States Navy during World War II, delivering pumps for engine manufacturers including Buda, Caterpillar, Chris-Craft, Cummins, Gray, Hercules, and Packard.

What Sherwood Offers in Water Pump & Components

Sherwood provides some of the most reliable bronze raw water pumps, impellers, and service parts on the market — engineered specifically to keep marine engines running cool under demanding conditions. The Sherwood pump lineup includes flange-mounted engine cooling pumps, pulley-driven engine cooling pumps, and crankshaft-mounted engine cooling pumps.

The full spectrum of Sherwood Water Pump & Components products covers every need from complete pump assemblies to individual service parts:

• Raw Water Pumps: Sherwood raw water pumps are essential components in marine engine cooling systems, efficiently circulating seawater to cool your engine.
• Impellers: The heart of any Sherwood raw water pump is its impeller — a flexible, wear-prone part that requires regular inspection and replacement to maintain peak flow.
• Rebuild & Repair Kits: A large range of Sherwood pump spares are available, including impellers, pulleys, service/repair kits, shafts, seals, gaskets & o-rings, bodies & housings, bearings, end covers, cam plates, wear plates, and cam liners.

Why Choose Genuine Sherwood Water Pump Components?

The seawater pump is the heart of the marine engine, supplying continuous water flow to maintain consistent engine temperatures — and the number one reason for premature engine wear is overheating. Using genuine Sherwood parts means you're getting components that are engine-tested and engine-specified, not aftermarket approximations.

Over the years, Sherwood seawater pumps have developed a reputation for excellence in quality, and today, as part of Pentair, the Sherwood brand has become the seawater pump of choice for many of the world's most prestigious engine manufacturers.
