Technical Specifications & Operating Thresholds
Cross-verify your equipment's operating pressure curves and circuit flow rates with our engineering master specs below:
| Parameter Parameter | Shaft-End Section (25V Frame) | Cover-End Section (20V Frame) | Operating Limit Benefit |
|---|---|---|---|
| Nominal Displacement Flow | 21 USgpm (at 1200 rpm, 6.9 bar) | 14 USgpm (at 1200 rpm, 6.9 bar) | Combines high-volume action and medium-volume pilot control. |
| Max Operating Pressure | 172 bar (17.2 MPa / 2500 PSI) | 172 bar (17.2 MPa / 2500 PSI) | Withstands continuous high clamping loads without housing fatigue. |
| Rated Rotation Speed | 600 - 1800 r/min (RPM) | 600 - 1800 r/min (RPM) | Pairs perfectly with standard industrial electric AC/DC motors. |
Nomenclature Coding Decoded: 2520V-21A14-1CC-22R
| Code segment | Technical Specifications Meaning | System Installation Match |
|---|---|---|
| 2520V | Double Intra-Vane Type High-Pressure Pump Series | Standardized physical footprint for 25V (front) and 20V (rear) frames. |

Precision Manufacturing: Why Heavy Industry Buyers Partner with YHDE
Dual high-pressure pumps running continuously in molding and press workshops endure relentless fluid friction and volumetric loading stresses. Poorly ground generic trading pumps bypass oil internally, leading to immense system heat, early pressure dropoffs, and immediate seal degradation. We defeat these structural vulnerabilities directly at our factory:
Intra-Vane Pressure Compensation Design: Our 2520V cartridges utilize the intra-vane technique. Oil pressure applies balancing forces under the vane pins, minimizing rotor ring wear patterns and holding volumetric efficiency at a steady 92%-95% under pressure loads.
Honed Micron Tolerances: Stator cam ring tracking contours and rotor side sealing faces are ground to sub-micron clearances on specialized vertical CNC grinders, locking noise levels below 68 dB.
100% Full-Load Bench Calibration: Every single double pump is dynamic tested on our hydraulic calibration bench up to its maximum rated 172 bar limit. We guarantee zero start-up bypass issues or pressure drops out of the box.
Pro Maintenance Insight: Escape the Destructive "Sandpaper Effect"
**When should you execute an urgent pump overhaul?** If your double system displays localized oil overheating, a noticeable drop in stroke cycle speed, or produces a harsh metallic screaming from the housing, internal vane tracking degradation is actively happening.
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, scrub intake suction strainers, and install a brand-new 10-micron absolute premium return fluid filter concurrently with the new pump unit installation.
