Applications
Machine Tools & Industrial Automation:A preferred choice for CNC machines, injection molding equipment, and automated assembly lines, where the low-pulsation, low-noise IPH design ensures smooth, consistent power delivery for precision actuators and clamping systems.
Hydraulic Power Units (HPUs):Ideal for small to medium hydraulic power packs, offering reliable, efficient performance in stationary systems. Its compact footprint and high power-to-weight ratio make it perfect for limited-space installations in workshop and factory environments.
Light Mobile & Material Handling:Well-suited for small lift tables, pallet stackers, and compact conveyor systems. The IPH‑2A‑5‑11’s pressure-balanced design maintains high efficiency under varying loads, ensuring stable operation in continuous-duty applications.
Agricultural & Construction Auxiliary Systems:Commonly used for auxiliary circuits in farm machinery and small construction equipment, such as steering assists, lift arms, and auxiliary tool drives. Its tolerance to fluid contamination makes it reliable in harsh outdoor conditions.
General Industrial Machinery:Versatile for use in presses, presses, packaging machinery, and process equipment requiring steady, low-noise hydraulic power. The pump’s consistent performance and low maintenance needs support long, uninterrupted production cycles.
IPH‑2A‑5‑11 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Internal Gear Design: Unlike external gear pumps, the IPH’s trochoidal profile delivers lower flow pulsation and quieter operation, making it ideal for noise‑sensitive industrial applications.
Pressure‑Balanced Clearance Control: Advanced pressure‑balanced side plates automatically adjust internal clearances to compensate for wear, maintaining high efficiency over the pump’s lifespan.
Compact, High‑Efficiency Build: Its compact footprint delivers high power‑to‑size ratio, with lower noise and vibration than many similarly sized external gear pumps.
The IPH‑2A‑5‑11 is optimized for medium‑pressure industrial use.
Continuous Pressure: Up to 16 MPa (2,320 psi).
Intermittent/Peak Pressure: Up to 21 MPa (3,000 psi), with short‑term peak capability up to 25 MPa (3,625 psi).
This stable pressure performance makes it ideal for machine tools, automation, and general industrial hydraulic circuits.
Yes, the IPH‑2A‑5‑11 is a high‑quality, drop‑in alternative for many premium compact gear pumps. It is often used as a replacement or upgrade for:
Similar‑displacement Nachi IPH‑2 variants.
Comparable internal gear pumps from other manufacturers, such as Sumitomo or Rexroth internal gear pumps.
To ensure a successful swap, verify the Mounting Flange (SAE “A” foot mount), Rotation (clockwise, shaft‑end view), and Displacement (5.24 cm³/rev) to match your existing system.
To protect the precision gears, bushings, and pressure‑balanced plates, the following is recommended:
Oil Type: Premium mineral‑based hydraulic fluids with strong anti‑wear (AW) and anti‑foam additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100–150 SUS (20–30 cSt), suitable for continuous industrial use.
Filtration: Cleanliness is critical for maintaining efficiency and preventing wear. A minimum filtration level of ISO 4406 18/16/13 is recommended to protect the pump’s precision components.
The IPH‑2A‑5‑11 operates reliably within the following speed range:
Continuous Speed: 600–2,000 rpm, with optimal performance at 1,200–1,800 rpm for standard hydraulic power units.
The pump’s design ensures stable flow and efficiency across the entire range, making it suitable for both low‑speed and medium‑speed industrial applications.

IPH‑2A‑5‑11 pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
