Shark offers over 90 commercial and industrial-grade hot and cold-water models that are built to last, yet are affordably priced. Here are just a few reasons why Shark pressure washers are a smart and cost-effective buy: Advanced seal technology in all high-pressure pumps U-Seal pump technology provides better performance and longer life on the seals. U-Seals handle higher temperatures up to 185°F and does a better job spreading the load against the seal and manifold. Durability Rugged chassis made of 10-gauge steel and painted with black wrinkle paint for all-weather resistance. Belt-drive units have notched V-belts and cast-iron pulleys to reduce belt slippage and extend pump life. Most models feature reliable Honda engines Safety thermal pump saver valve protects against hot-water damage by venting re-circulated water. Four vibration isolators are mounted under the engine to reduce vibration, wear and tear on components.
