Vickers 2520V Double Vane Pump | 2520V12A5 2520V14A5 Hydraulic Pump Replacement

Genlu Hydraulic excels as a world-class engineered product manufacturer, component metallurgist, and strategic global supplier of high-capacity, heavy-duty industrial fluid power pumps and modular quick-change cartridge sub-assemblies. The 2520V Series Industrial Axially Balanced Double Vane Pump is purpose-built as a robust, high-volumetric-efficiency, and 100% drop-in interchangeable alternative to the industrial fluid automation baseline—the Eaton Vickers flagship V series double vane pumps (encompassing 2520V, 3525V, 4520V, 4525V, and 4535V frameworks). We support standard production schedules and rapid distribution channels for highly requested industrial configurations such as 2520V12A5-1CC-22-R, 2520V14A5-1AA-22-R, and 2520V17A5-1AA-22-R.

Within modern manufacturing plant floors, automated injection molding cells, heavy die-casting stations, and recycling scrap shears, the system actuators demand an optimization between “high-volume low-pressure fast approach” and “low-volume high-pressure intense clamping” cycles. The double pump layout resolves this multi-circuit dynamic through two independent cartridge cores sharing a single input drive shaft, reducing electric motor overhead while boosting thermodynamic efficiency. Genlu’s 2520V double pumps align flawlessly with original factory blueprints. We guarantee 100% plug-and-play retrofit engineering across standard SAE 2-bolt mounting flanges, primary parallel keyed shafts, center-to-center distances of the shared suction inlet and independent pressure outlets, and internal vane-to-cam ring mechanics. Prior to final dispatch authorization, every single double pump undergoes 100% Full-Simulation Condition Testing on digitized hydraulic test loops to verify independent flow consistency and cross-port pressure performance under maximum industrial ratings.

Key Technical Advantages:

• Hydraulically Balanced Core Geometry for Extended Bearing Life: Both internal cartridge groups of the 2520V double pump incorporate dual-symmetric suction and discharge chamber geometries. Fluid-induced radial forces acting on the inner core are perfectly counter-balanced within the cam ring ring layout. This zero net radial bearing load prevents rotational shaft deflection, extending mechanical bearing and shaft seal life under continuous dual-circuit pressure spikes.

• 12-Vane High-Density Rotor Layout for Ultra-Low Noise Plant Profiles: The internal rotors are fitted with a precise 12-vane layout designed to deliver smooth fluid transition curves compared to heavy-pulse mobile pumps. Combined with hydrostatic bi-metal side plates featuring micro-machined involute relief grooves, the pump minimizes fluid-borne low-frequency pressure pulsations. Total operating noise is held between 62 and 65 dB, making it an excellent solution for sound-sensitive industrial factory floors.

• Fully Modular Drop-In Twin Cartridge Kit Rebuild System: The front and rear pump sections contain completely independent, self-contained cartridge modules (comprising the cam ring, rotor, vanes, bi-metal plates, and standard sealing rings). If contamination wear occurs on one circuit, maintenance crews can replace the isolated worn cartridge core locally by removing the rear housing cover, without unplumbing the entire pump or disconnecting rigid lines, minimizing factory downtime.

• Multi-Position Flexible Porting Orientation Structures: The 2520V cast outer architecture offers high installation flexibility. By adjusting the clocking alignment of the center ring and rear cover bolts relative to the main suction hub, discharge port A and discharge port B can be independently indexed at 0°, 90°, 180°, and 270° increments (e.g., the 1CC porting designation), optimizing pipe routing within confined hydraulic reservoir enclosures.

Application Areas:

• Medium-to-Heavy Duty Industrial Hydraulic Compaction Stations: Multi-circuit power packs powering rubber vulcanizing presses, scrap metal balers, and automated refractory brick casting equipment.

• High-Yield Plastics & Rubber Molding Machinery: Clamping, core-pulling, and high-velocity injection booster lines for automated servo-hydraulic injection molding machines.

• High-Frequency Metalworking Automation: Centralized hydraulic power units for heavy-gauge sheet metal CNC press brakes, industrial plate shearing lines, and multi-station machine tool clamping lines.

Expert Maintenance Tips:

• Verify Outlet Clocking Orientation Codes (AA vs. CC) to Prevent Piping Mismatches: When replacing a double pump unit, look closely at the port mapping code (such as switching a 2520V12A5-1CC-22-R with a 1AA model). The letters AA and CC define the physical spatial angles of the high-pressure outlets relative to the shared intake. Selecting the wrong code means the ports will face the wrong direction, making it impossible to bolt on rigid factory steel lines even though the internal capacities are identical.

• Enforce Initial Electric Motor Jogging and Low-Speed Threshold (Never Run Below 600 RPM): These industrial single-vane cartridges depend entirely on the centrifugal force generated by rotor rotation to fling the vanes out of their slots to seal against the inner cam ring contour. If started below 600 rpm (such as under improperly calibrated variable frequency drive parameters), the vanes will fail to seat, causing severe oil bypass and dry metal friction that can gall the cam ring within seconds. Always pre-fill the common suction hub with clean system oil and execute 2 to 3 quick motor bumps (jogging) to instantly prime both cartridge blocks.

• Strict Inspection of the Common Large Suction Line Flange to Avoid Cavitation: Because this double pump shares a single large 2-1/2″ SAE suction flange, the inlet fluid velocity is high. Any micro-fissure or loose bolt on the suction flange gasket will introduce ambient air into the core. These micro-bubbles implode violently when encountering the high-pressure discharge zone, resulting in loud metallic crackling noises, pressure loss, and honeycomb cavitation erosion. Maintain strict oil filtration metrics, ensuring the reservoir oil is continuously filtered to an ISO 4406 18/15 or NAS 8 cleanliness standard.
