Reliable, Low-Noise, and Efficient Hydraulic Solutions for Industrial and Mobile Applications.
A vane pump is a positive-displacement pump known for its quiet operation and consistent efficiency across a wide range of speeds. It consists of vanes mounted to a rotor that rotates inside a cam ring. As the rotor turns, centrifugal force (and often hydraulic pressure) pushes the vanes out against the ring, creating chambers that trap fluid at the inlet and discharge it at the outlet.
Vane pumps are available in both fixed displacement and variable displacement designs. Our vane pumps feature high-strength cast iron housings, precision-ground cam rings, and pressure-balanced designs that minimize internal leakage. With operating pressures up to 3,000 PSI and a flow range covering most industrial needs, they are the preferred choice for plastic injection molding, die casting, machine tools, and material handling equipment. When you require a pump that balances smooth flow with low acoustic noise, our vane pumps are the definitive solution.
Quiet performance is the hallmark of a high-quality vane pump. By utilizing a multi-vane design and optimized timing grooves, our pumps significantly reduce pressure ripples and vibration. This makes them ideal for indoor industrial environments where noise control is critical for operator safety and comfort, without sacrificing power density.
Efficiency stays high throughout the pump's life. Our vane pumps utilize a "pressure-balanced" design, where hydraulic forces are equalized within the internal components. This reduces the load on bearings and prevents uneven wear on the cam ring and vanes. Even as components bed in, the vanes automatically adjust to maintain a tight seal, ensuring consistent flow and volumetric efficiency exceeding 90%.
Minimize downtime with our "cartridge kit" construction. Unlike other pump types that require complete replacement upon failure, our vane pumps are designed so that the internal rotating elements (the cartridge) can be replaced in minutes without removing the pump from its mount. This service-friendly approach reduces long-term O&M costs and keeps your hydraulic systems running with minimal interruption.
Yagang hydraulic cylinders ensure precision motion control for automated production lines. They address the need for reliable, low-maintenance actuation in packaging, handling, and assembly systems, minimizing downtime in continuous operations.
For high-speed, repetitive cycles in CNC and stamping equipment, Yagang hydraulic cylinders provide exceptional accuracy and rigidity. They are engineered to combat wear and maintain positioning precision over long service life.
As the core power component, Yagang hydraulic cylinders deliver consistent, high-force output for molding and forging. They are built to withstand extreme pressure spikes and ensure stable platen movement, crucial for product quality.
In high-heat, high-shock mill environments, Yagang’s heavy-duty hydraulic cylinders offer robust performance for rolling and handling. Their design focuses on heat resistance and structural integrity to withstand punishing conditions.
Subjected to extreme abrasion and shock loads in crushers and kilns, Yagang hydraulic cylinders are built for toughness. Their robust design prioritizes seal protection and piston rod strength to maximize uptime in the harshest environments.

We offer comprehensive technical documentation and readily available remote support for troubleshooting and maintenance guidance, ensuring sustained peak performance throughout the cylinder’s lifespan.
Gear pumps are the simplest and most affordable—fixed displacement, good for pressures up to 3,600 PSI, tolerant of contamination. Vane pumps are quieter and have better low-speed efficiency but are more sensitive to oil cleanliness. Piston pumps handle the highest pressures (5,000+ PSI) and offer variable displacement options but cost more. Choose gear pumps for cost-sensitive applications with moderate pressure requirements.
Our high-pressure vane pumps are rated for continuous operation up to 210–250 bar (3,000–3,600 PSI). They are specifically engineered to provide a stable flow even under fluctuating load conditions, outperforming standard light-duty models.
Absolutely. We specialize in manufacturing vane pumps that are dimensionally and functionally interchangeable with leading brands like Vickers (V/VQ series), Denison (T6/T7 series), and Yuken (PV2R series). Our engineering team can cross-reference your current part numbers to ensure a perfect fit for your existing SAE or ISO mounting, shaft, and port configurations.
For standard models and common cartridge kits, we maintain a robust inventory with a lead time of 3–5 business days. For large-scale wholesale orders or custom OEM configurations (special shafts or porting), the typical production cycle is 15–20 days. We offer flexible shipping options including air freight for urgent repairs and sea freight for bulk distribution.
Quality is our priority. Every single vane pump and cartridge kit undergoes a 100% dynamic test on our factory benches. We test for volumetric efficiency, mechanical noise, and pressure-holding capability. Each unit is assigned a unique serial number for tracking, and we provide a standard 12-month warranty against manufacturing defects.
