IPVP & IPVS Series Servo Hydraulic Pump | IPVP5-40, IPVS3-10, IPVP4-25 | Internal Gear Pump

IPVP & IPVS Series High-Performance Servo Internal Gear Pumps

Product Overview: The IPVP and IPVS Series represent the gold standard for modern servo-driven hydraulic systems. As ultra-quiet, high-pressure internal gear pumps, they are engineered specifically for high-end machinery such as injection molding machines, die-casting machines, and CNC bending machines. This featured selection includes core models: IPVP5-40-101, IPVS3-10-101, the precision IPVP4-25-171, and the high-flow IPVP6-80-101. Their unique gap-compensation technology ensures exceptional pressure stability and minimal operational noise under variable-speed servo conditions.

Key Technical Advantages:

• Servo Drive Optimization: Purpose-built for frequent acceleration and deceleration of servo motors. It supports ultra-low speed pressure holding with rapid response times—essential for high-precision, energy-saving hydraulic circuits.

• Dual Gap Compensation: Featuring patented axial and radial pressure compensation, maintaining volumetric efficiencies over 95% throughout the pump’s service life, which effectively minimizes oil overheating.

• Ultra-Quiet & Low Pulsation: The specialized internal meshing gear profile delivers decibel levels far lower than traditional external pumps. The smooth flow output drastically reduces system vibration and extends the lifespan of seals and valves.

• 100% Direct Replacement: Strictly adheres to international industrial standards. Codes such as 101 (Standard Mounting) and 171 (Specific Flange) guarantee that pilot diameters, shaft ends (keyed/splined), and port positions are 100% compatible with the original equipment.

• Extreme Durability: The reinforced cast iron housing combined with high-tensile gear sets allows for stable operation at 31.5 MPa (315 Bar) continuous pressure for tens of thousands of hours.
