RKV4G40-VRT-PKG | 4.0 GPM 4000 PSI Triplex Pump, VRT Unloader

RKV4G40-VRT-PKG Triplex Pump Package

The RKV4G40-VRT-PKG is a professional-grade triplex plunger pump package engineered for high-demand cleaning
systems requiring dependable pressure, steady flow, and simplified installation. Delivering 4.0 GPM at
4,000 PSI, this assembly is built for contractors, fleet operators, and industrial facilities that need
durable, consistent performance in continuous-duty environments. The inclusion of a factory-matched VRT
unloader/regulator transforms the pump into a turnkey solution ready for integration into engine-driven
pressure washer platforms. With an F24 flange and 1″ hollow engine shaft compatibility, the package fits
directly onto common gas and diesel powerplants used in commercial cleaning equipment.

Constructed with ceramic plungers, stainless-steel valves, a forged brass manifold, and oversized bearings,
the RKV4G40-VRT-PKG is designed for long service life under rugged operating conditions. Its combination of
hydraulic efficiency, mechanical stability, and modular service access makes it a preferred choice for
trailer-mounted rigs, wash bays, municipal maintenance, and industrial cleaning applications where
reliability and output are equally important.
