IPVP & IPVAP Series Servo Hydraulic Pump | IPVP4-32, IPVP4-20, IPV3-3.5 | Internal Gear Pump

IPVP & IPVAP Series High-Performance Servo Internal Gear Pumps

Product Overview: The IPVP and IPVAP Series represent the benchmark 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: IPVP4-32-171, IPVP4-20-171, and the precision-engineered compact models IPV3-3.5-101 and IPVAP3-3.5-101. 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 the frequent acceleration and deceleration cycles of servo motors. It supports stable high-pressure holding at ultra-low speeds (down to 10 RPM)—essential for high-precision, low-energy servo circuits.

• Patented Dual Gap Compensation: Featuring automated axial and radial pressure compensation mechanisms, 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 life of seals and valves.

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

• Heavy-Duty Pressure Resilience: 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.
