Nachi IPH Gear Pump
- High Efficiency: The patented axial and radial pressure loading system of the Nachi IPH gear pump enables it to have a high output energy—becoming as efficient as possible—and create pressures of up to 30MPa (306 kgf/cm²).
- Durability: It is capable of working for extended periods without failing; this robustness allows it to deliver dependable performance throughout its life cycle.
- Quiet Operation: Noise produced by this unit when in use is significantly reduced due to the utilization of an involute short-tooth gear with modified geometry which attenuates pulsations during operation thus ensuring quietness.
- Ease of Maintenance: Simple design facilitates convenient maintenance thereby reducing inspection downtime necessary for repairs hence saving on service charges.
- Wide Range of Capacities: Different applications can be catered for effectively because the IPH series has various sizes ranging from 3.6 to 125.9 cm³/rev.
- Installation Compatibility: These models can replace earlier versions since they share mounting dimensions, except that seals between sizes IPH-3 & IPH-4 and design numbers 10 – 12 are not common components.
- Operating Fluid and Temperature Range: Hydraulic fluids supported include R&O as well wear resistant types having ISO VG32 through VG68 grades where ambient temperatures must stay within 5 -65 °C.
- Multiple Mounting Options: Both foot-mounted or flange-mounted arrangements are available thus allowing users greater flexibility during setup depending on specific operational requirements.
