Sherwood Pump P2708X Raw Water Engine Cooling Pump for Cummins QSB

Manufacturer

Sherwood Pump

<p>Sherwood Pump's history dates back to 1903, when William Sherwood and his business partner David Buick operated a copper brass plumbing business. After parting ways, Sherwood developed the business into a foundry and machine shop, sought out by Henry Ford and the Dodge brothers for Detroit's expanding auto-driven industries. In the 1920s, entrepreneur Chris Smith's company, Chris-Craft, incorporated William Sherwood's plumbing expertise to develop the first seawater pumps for marine inboard engines.</p> <h3>A Legacy of Marine Engineering Excellence</h3> <p>During World War II, a Chris-Craft personnel carrier equipped with a Sherwood pump was the first Allied landing craft to hit Normandy beaches on June 6, 1944. During this period, Sherwood supplied pumps to marine engines from Buda, Caterpillar, Cummins, Gray, Hercules, and Packard. Following WWII, as the pleasure boating industry grew, Sherwood evolved to accommodate the exacting cooling pump needs of this expanding market, keeping pace with new engines from Chrysler, Ford, and GM through relationships with Chris-Craft, Chrysler Marine, Crusader, and OMC.</p> <h3>Industry-Leading Cooling Solutions</h3> <p>Today, Sherwood remains the trusted choice for <a href="/7562-sherwood-pump-engine-cooling-pumps-accessories-200368">engine cooling pumps and accessories</a> across both pleasure and commercial marine applications. The seawater pump serves as the heart of the marine engine, supplying continuous water flow to maintain consistent engine temperatures—critical because the number one reason for premature engine wear is overheating. Now part of Pentair, the Sherwood brand has become the seawater pump of choice for many of the world's most prestigious engine manufacturers.</p> <p>Sherwood's comprehensive line of <a href="/7562-sherwood-pump-engine-water-pump-2208">engine water pumps</a> features multiple mounting configurations including flange-mounted, pulley-driven, and crankshaft-mounted designs. These pumps are available for a wide range of applications varying in type, flow requirements, speed, size, and weight. Each pump is engineered to meet the specific cooling demands of modern marine engines, whether for propulsion or generator sets.</p> <h3>Genuine Replacement Parts and Service Components</h3> <p>Maintaining peak engine performance requires regular service intervals and quality components. Sherwood's <a href="/7562-sherwood-pump-impellers-200573">impellers</a> are designed as precision-engineered wear components that should be replaced annually for optimal engine health. Genuine Sherwood replacement parts are often copied, but never duplicated. The company offers complete repair and service kits containing all necessary gaskets, seals, and wear plates to restore pumps to original specifications.</p> <p>For system protection, Sherwood manufactures <a href="/7562-sherwood-pump-sea-strainers-200906">sea strainers</a> that prevent debris from damaging downstream cooling system components. These strainers are designed to be durable and easy to clean, featuring non-corrosive construction that ensures long service life. Available in multiple port sizes, they provide essential filtration for raw water intake systems.</p> <p>Sherwood also offers specialized <a href="/7562-sherwood-pump-automatic-transmission-overhaul-kit-10998">automatic transmission overhaul kits</a> for marine drive systems, rounding out their comprehensive portfolio of marine power transmission components. With over a century of manufacturing expertise and a reputation built on reliability, Sherwood Pump continues to set the standard for marine engine cooling solutions.</p>
