Product Overview

The MOOG HP-R18A1-RKP063KM28B1Z00 / D954-2061/F is a high-performance radial piston pump engineered by MOOG for demanding industrial hydraulic systems requiring precise high-pressure delivery and exceptional volumetric efficiency. This fixed-displacement radial piston pump operates on the proven radial piston principle, where multiple pistons arranged radially around a central eccentric shaft generate flow through positive displacement. The RKP series is recognized for its robust construction, high pressure capability, and consistent performance in continuous-duty applications. With a displacement of approximately 63 cm³/rev, this model is ideally suited for systems requiring reliable high-pressure hydraulic power, such as industrial presses, injection molding machines, and heavy-duty manufacturing equipment. The pump’s design ensures minimal pulsation, low noise emission, and long service life even under the most severe operating conditions.
