RKV55G40HD-F24 5.5 GPM 4000 PSI | Heavy-Duty Triplex

AR RKV55G40HD-F24 Triplex Plunger Pump

The AR RKV55G40HD-F24 is a high-output triplex plunger pump engineered for demanding wash applications that
require both strong pressure and significant water volume. Delivering 5.5 GPM at 4,000 PSI and operating at
3,400 RPM, this model supports contractor-grade, industrial, and heavy-equipment cleaning environments where
throughput, durability, and consistent performance are essential. With an F24 engine flange and a 1″ hollow
keyway shaft, the pump mounts directly to compatible gas or diesel engines, providing reliable torque transfer
with minimal alignment complexity.

Built using premium materials—including ceramic plungers, stainless-steel valves, and a nickel-plated pump
head—the RKV55G40HD-F24 withstands continuous-duty operation in harsh, high-pressure environments. Its
heavy-duty crankcase, oversized bearings, and pressurized lubrication system ensure reliable long-term service,
making this pump a preferred choice for high-flow industrial cleaning tasks and large-area surface preparation
work.
