Facing Production Line Stalls Due to a Broken Yuken PV2R12 Double Pump? Restore Pressure in 48 Hours!
When a high-performance double vane pump loses pressure or suffers severe internal wear in your plastic injection molding machinery, metal bending tools, or automated industrial presses, waiting 12 to 16 weeks for expensive original imports directly drains your workshop's daily profitability.
Our premium Yuken-type PV2R12-12-47-F-REAA-41 Double Hydraulic Vane Pump serves as a seamless, 100% mechanical "drop-in" replacement. Built in our ISO-compliant source manufacturing facility with 9+ years of micro-tolerance hydraulic tooling mastery, this dual-flow pump restores native system flow speed and high-pressure limits—slashing your procurement and MRO budget by up to 70%.
100% Physical Form Match: Mounting flanges, drive shaft keys, port configurations, and bolt holes match Yuken specs identically with zero pipeline modifications required.
Fast Factory Dispatch: Units are built, dynamic full-load bench tested to 210 bar, and shipped worldwide within 24-48 hours to eliminate costly downtime.

Precision Tooling: Engineered for High Volumetric Output & Low Noise
Running a double pump continuously under heavy workshop cycles demands extreme micro-dimensional accuracy. Non-specialized traders supply castings with unground landing zones, leading to early pressure bypass, high operating heat, and rapid volumetric decay. We eliminate these failure modes directly on our factory floor:
Circular Arc Vane Geometry: Our PV2R series incorporates dual-vane pin tracking mechanisms. Vanes are hydrostatically balanced under peak line pressures, significantly lowering friction against the stator ring and dropping noise below 65 dB(A) for comfortable workshop operations.
Sub-Micron CNC Profiling: Stator cam ring tracking contours and rotor side sealing plates are ground to sub-micron tolerances on specialized vertical CNC profile grinders, guaranteeing zero internal boundary leakage.
100% Full-Load Bench Test Validation: Every single PV2R12 double pump is dynamically tested up to its peak 21 MPa limits on our hydraulic calibration bench. We verify both chambers simultaneously before crating.
Pro Maintenance Insight: Escape the Hostile "Sandpaper Effect"
When should you execute an urgent pump overhaul? If your central system starts presenting sudden cycle slowdowns under load, localized oil reservoir temperature spikes, or produces a harsh, high-frequency metallic screaming from the pump housing, internal vane tracking degradation has begun.
If your technical crew simply bolts a fresh new replacement pump onto the system without deep cleaning the circuit, these residual hard particles will act as an aggressive grit abrasive—creating a devastating "sandpaper effect". They will instantly score the freshly ground stator profile rings, destroying your new double pump within a few operating hours.
Mandatory Procedure: Meticulously drain and flush the reservoir tank, thoroughly scrub the suction intake strainers, and install a brand-new 10-micron absolute premium return fluid filter concurrently with the new pump unit installation.
