MOOG D952-2026/C Fixed Displacement Radial Piston Pump (32cc, 7 Piston, 350 bar) for Industrial Application

Model Code Interpretation While Moog uses "D952" as a top-level assembly part number for the RKP-II family, this specific configuration (D952-2026) generally corresponds to the following technical profile: Product Line: RKP-II (Radial Piston Pump, 2nd Generation). Displacement: $32\text{ cm}^3\text{/rev}$ ($1.95\text{ in}^3\text{/rev}$). Pressure Rating: Standard series, rated for $280\text{ bar}$ ($4,000\text{ psi}$) continuous and $350\text{ bar}$ ($5,000\text{ psi}$) peak. Compensator (F1): Adjustable pressure compensator ($30\text{–}105\text{ bar}$ range). This means the pump will automatically reduce its flow once the set pressure is reached. Rotational Direction: Usually Left-hand (Counter-clockwise) rotation (indicated by the "L" in the sub-code for this assembly). Technical Specifications Feature Value Piston Count 7 pistons (Note: larger sizes $63\text{--}250\text{ cc}$ use 9 pistons) Max Speed $2,800\text{ RPM}$ Drive Torque (at 280 bar) Approx. $145\text{ Nm}$ Shaft Type Usually a splined or keyed shaft conforming to SAE or ISO standards Typical Fluid Mineral oil (standard NBR seals)
