Description

The CAT Pumps Model 550 is a robust triplex plunger pump designed for high-pressure applications in industrial, commercial, and cleaning sectors. This positive displacement pump delivers a consistent flow of 5 GPM with a pressure range of 1000-3000 PSI, making it ideal for pressure washing, misting systems, reverse osmosis, and chemical injection. Key features include a durable cast iron crankcase, ceramic plungers for extended life, and a belt-drive system for flexible RPM adjustments. Benefits include exceptional reliability ('The Pumps with 9 Lives' reputation), low maintenance due to its oil-bath lubrication, and high efficiency in demanding environments. Compared to similar pumps from competitors like General Pump or AR, the CAT 550 offers superior longevity and rebuildability, reducing long-term costs. Drawbacks may include its weight and the need for proper alignment in belt-driven setups. This preowned unit is in 'like new' condition, showing minimal wear, and is suitable for water, oil, or chemical handling with appropriate seals. Overall, it's a versatile, high-performance pump for users seeking durability over initial cost savings.
