Description
The General Pump (GP) RW 5535S is a powerhouse in the RW Series (also known as the “Rear-Ported” Evolution series). This is an industrial-grade, solid-shaft triplex plunger pump designed for high-flow, high-pressure applications. Since it operates at 1450 RPM, it is intended for belt-drive, gearbox, or flexible-coupling systems rather than direct-drive high-speed motors.
