Short Description
Premium factory-direct aftermarket Eaton Vickers PVXS Series High-Pressure Variable Displacement Axial Piston Pumps (Complete Assemblies), precision-engineered as 100% plug-and-play interchangeable power solutions for severe-duty industrial and marine open circuits. Covering full frame displacements from PVXS060, PVXS090, PVXS130, PVXS180, to PVXS250, these heavy-tonnage complete pump assemblies utilize ultra-rigid nodular iron housings and upgraded bimetallic rotary groups. Every unit is comprehensively validated to sustain continuous heavy-cycle operating pressures up to 350 bar and intermittent peak shock loads up to 420 bar in forging presses, steel mill HPUs, and marine deck machinery.
Key Technical Highlights
-
100% Plug-and-Play Drop-In OEM Fitment: Formulated strictly according to the original Eaton Vickers PVXS micro-metric factory blueprints. Standard SAE high-pressure mounting interfaces, splined drive shafts, and SAE Code 62 high-pressure delivery ports align perfectly with your existing industrial piping—zero modification required.
-
Heavy-Wall Anti-Deflection Design: Features premium thick-walled nodular cast iron pump casings. Engineered to completely eliminate internal component structural deflection and micro-clearance warping under continuous, high-frequency 350 bar operational stresses.
-
Hydro-Dynamically Balanced Rotators: Built with 9-piston rotating groups forged from structural alloy steel, induction hardened to 60-62 HRC, and paired with micro-lapped bimetal cylinder blocks to guarantee absolute zero-seizure safety under extreme thermal shifts.
-
Mastery Over Specialized Hydro-Mechanical Regulators: Fully compatible and factory-calibrated for complex industrial control heads, including DF (Pressure/Flow Control), LR (Hyperbolic Power/Torque Limiter), and SP (Proportional Valve Control) to blend seamlessly with your host plant’s PLC system logic.

FAQ
Q1: Eaton Vickers PVXS series pumps deal with extreme pressure parameters. How do you guarantee the replacement pump will match my factory’s specialized model layout?
A: High-pressure industrial systems leave zero room for error. The PVXS coding architecture contains strict identifiers indicating the design number series, shaft seal compounds (such as high-temperature FKM for synthetic fire-resistant fluids used in steel mills), shaft splines, and exact power control settings (e.g., PVXS130-M-R-DF-0000-000). To guarantee a seamless, zero-risk drop-in swap, our engineering division cross-checks your original alphanumeric nameplate or your facility’s system design diagrams before beginning the precision assembly.
Q2: Heavy-duty metal processing and steel mills require exact torque-matching. How does your factory test and calibrate the PVXS hyper-power (LR) control heads?
A: An uncalibrated power regulator under 350 bar will either stall your plant’s prime motor or cause catastrophic hydraulic shock loops. At our factory, every complete PVXS pump assembly is subjected to multi-hour heavy dynamic load profiling. We trace and adjust the hyperbolic power limit curves ($\text{P-Q}$ response) under a continuous 350 bar testing envelope on our specialized facilities, ensuring the unit operates with perfect accuracy right out of the crate.
