Review DEVILBISS Excell Pressure Washer Pump Untested Working When Removed

The Devilbiss D28704 Excell Pressure Washer Pump is a heavy-duty, industrial-grade component designed to deliver reliable and consistent performance for pressure washing applications. This triplex pump boasts a robust cast iron housing, which not only adds durability but also helps to dissipate heat generated during operation, ensuring stable performance even under heavy workloads.

The pump's triplex design features three plungers that move in a reciprocating motion to pump water through the system. The plungers are synchronously connected using a unique offset design, which minimizes pulsation and delivers a steady, smooth water flow. This design also results in superior suction ability, allowing the pump to effectively handle debris-laden water and maintain excellent suction performance.

The D28704 Excell Pump is equipped with a large 3.5-inch prime opening, which simplifies the priming process, reducing the time and effort required to fill the pump with water. An automatic air relief valve is integrated into the pump's design, which releases trapped air during operation, preventing water hammer and ensuring efficient water flow.

This pressure washer pump comes with a durable, industrial-grade brass inlet and outlet, which provides excellent resistance to corrosion and wear, ensuring long-lasting performance. The brass components are also threaded with UNF 1/2" NPT connections, making it easy to connect and disconnect hoses and other components as needed.

The Devilbiss D28704 Excell Pressure Washer Pump is capable of delivering a maximum pressure of 4,000 PSI (pounds per square inch) and a maximum flow rate of 4.5 GPM (gallons per minute). It is designed to be used with cold water and is suitable for a wide range of pressure washing applications, from residential cleaning tasks to commercial and industrial applications.

Overall, the Devilbiss D28704 Excell Pressure Washer Pump is an excellent choice for those seeking a robust, reliable, and high-performing pump for their pressure washing system.
