– easy commissioning due to automatic bleed facility, ensuring immediate system readiness without manual air purging delays. Operators can physically hear the swift, uninterrupted intake of fluid, bypassing the usual sputtering associated with trapped air pockets.
– low noise level operation, achieved through optimized vane chamfering and precision stator matching, keeping flow pulsation below 3% for a quiet, stable working environment that minimizes operator auditory fatigue on the factory floor.
– high bearing life because of hydrodynamically lubricated plain bearings, complemented by high-hardness alloy steel rotors and self-lubricating copper-based vanes for extended fault-free longevity under heavy loads. The dense, weighty construction of the rotor assembly provides tangible proof of its industrial resilience.
– bronze-faced starting and control plates, giving low friction characteristics during marginal lubrication conditions, protecting the core mechanism during cold starts when the hydraulic oil viscosity is at its thickest.

The 1PV2V3 series is engineered as a reliable core component in advanced hydraulic systems, widely applied in CNC machine tools, injection molding machinery, die-casting equipment, and heavy construction machinery. These pumps offer precise flow regulation and robust performance under diverse operating conditions, making them ideal for applications requiring dynamic pressure control and energy efficiency. By utilizing an advanced pressure compensation variable mechanism, this unit adaptively adjusts flow rates, which can significantly reduce system energy consumption by 20% to 30% compared to traditional fixed-displacement alternatives. This translates into a measurable improvement in operational cost-efficiency for large-scale facility managers.
The solid, cool metallic touch of the cast iron housing speaks to its industrial-grade durability, built to withstand the rigorous demands of continuous heavy-duty cycles. Furthermore, adopting standard flange and shaft end designs, this series provides exceptional interchangeability. It seamlessly integrates into existing setups, allowing for direct, modification-free replacement of mainstream international variable vane pumps, thereby drastically lowering system upgrade and retrofit costs.
Working Pressure Range: 12–100 bar (with peak up to 120 bar), providing the muscular force necessary for demanding industrial pressing and lifting tasks, delivering a consistent thrust you can rely on.
Displacement Range: 10–100 cc/rev, with variable adjustment capability that adapts instantly to shifting load requirements, ensuring fluid delivery matches exact mechanical demands without waste.
Model Designation Example: Suffix “MC25A1” indicates a precise displacement of 25 cc/rev, simplifying procurement and system integration for maintenance engineers.
Adjustment Precision: ±2% accuracy, response time ≤0.5 seconds—ideal for precision control environments where micro-second delays impact production quality and material integrity.
Efficiency Standards: Volumetric efficiency ≥92%, mechanical efficiency ≥85%, surpassing industry benchmarks for vane pump energy performance, reducing thermal waste, and keeping the external casing noticeably cooler during prolonged operation.
Temperature Management: Designed for continuous operation with oil temperature maintained at ≤65°C (cooling system recommended to preserve fluid viscosity and protect internal seals from premature degradation).
Construction: Cast iron housing with single-stage design, compatible with standard hydraulic oil media. Furthermore, it boasts an industrial-grade IP65 equivalent protection standard, allowing it to thrive in dusty, moisture-heavy outdoor engineering environments, shielded by its rugged exterior.
The flow regulation mechanism of the 1PV2V3 series is designed with operator ergonomics and precise control in mind. Flow is easily adjusted via an integrated handle system that provides immediate tactile feedback. When operators grip the adjustment ring, they will feel a smooth, resistance-free rotation, allowing for micro-adjustments without specialized tools. The distinct metallic click of the locking mechanism provides auditory confirmation that the setting is secure.
For light-load stabilization: Operators can adjust the grey lock nut and rotate the yellow ring clockwise in approximately 15° increments. Each increment offers a distinct, satisfying click, ensuring that the exact desired displacement is locked in securely, preventing accidental drift during operation.
Under heavy-load stall conditions: Use the blue lock nut and red adjusting ring similarly to restore stable pressure output. The firm resistance of the heavy-duty lock nut guarantees that even under severe machine vibrations, the pressure settings remain absolute. This intuitive, color-coded adjustment system significantly reduces setup times and minimizes operator error on the factory floor.
Every single pump undergoes 100% dynamic load testing for pressure, flow accuracy, and noise emissions before leaving our facility. This rigorous protocol ensures industrial-grade, zero-defect delivery. Manufactured in strict compliance with ISO 9001 quality management systems and CE safety standards, these units comfortably meet the stringent entry requirements of premium global industrial markets.
