IPVP Series Servo Hydraulic Pump | IPVP7-160, IPVP4-20, IPVP6-100 | Internal Gear Pump

IPVP Series High-Performance Servo Internal Gear Pumps

Product Overview: The IPVP Series represents the gold standard for modern servo-driven hydraulic systems. As an ultra-quiet, high-pressure internal gear pump, it is engineered specifically for premium machinery such as injection molding machines, large presses, and CNC bending machines. This featured selection includes core models: the high-flow IPVP7-160-111, the precision IPVP4-20-171, IPVP/4/13, and the specialized IPVP6-100-451. 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 high-frequency acceleration and deceleration of servo motors. It supports stable high-pressure holding at ultra-low speeds—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, effectively minimizing oil overheating.

• Ultra-Quiet & Low Pulsation: The specialized internal 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.

• Direct Replacement: Strictly adheres to international industrial standards. Suffix codes like 111 (Standard Mounting), 171 (Specific Flange), and 451 (Custom Configuration) 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, offering superior fatigue resistance in heavy-duty cycles.
