IPH-2A(B)-8-11 Gear pump

Nachi    IPH series gear pump:

1. Product overview
Nachi gear oil pump IPH-2A(B)-8-11 belongs to the IPH series internal meshing gear pump, with a displacement of 8.18cc/rev, a rated pressure of 11MPa, and a maximum pressure of up to 30Mpa.This series of pumps adopts a modified involute short tooth internal meshing design, which significantly reduces pulse and noise, and the noise is 5-10dB lower than that of traditional gear pumps during operation.The shell is made of aluminum alloy, has a compact structure, supports double or triple pump combinations, and adapts to the needs of multiple scenarios.
2. Core performance parameters
Parameter value description
The displacement of 8.18cc/rev discharges 8.18ml of liquid per revolution, and the flow rate is directly related to the speed.
The rated pressure is 11MPa and the continuous working pressure meets the needs of medium and low pressure hydraulic systems.
The maximum pressure is 30Mpa and can withstand pressure for a short time, which is suitable for high-pressure working conditions.
The speed range is 600-2000rpm, and the high-efficiency operating speed range, some models support higher speeds.
The low noise design with noise level ≤70dB is better than that of traditional gear pumps.
The weight is about 4.8kg, and the lightweight design is easy to install and maintain.
The applicable medium hydraulic oil (ISO VG32~68) needs to use wear-resistant oil to ensure the life of the pump body.
The oil temperature range is 5~65℃. When starting, the oil temperature must be ≥5℃ to avoid low temperature start-up wear.
The suction pressure is -0.03~+0.03MPa, and the suction port speed is≤2m/s to prevent cavitation.
3.the technical characteristics
High efficiency and energy saving
Using axial and radial pressure loading technology, the volumetric efficiency is more than 95%, and the full efficiency is more than 90% at a pressure of 30Mpa.
The semi-cylindrical swash plate is designed to stabilize the oil output, reduce flow loss and reduce power loss.
Low noise operation
The meshing design of the involute short teeth is corrected to reduce pulse and noise, and the operation is quiet.
The sliding boots, swashbuckles, oil distribution pan and other parts adopt an anechoic structure to further reduce noise.
Strong durability
Made of high-quality materials, with excellent wear resistance and a service life of up to tens of thousands of hours.
The structure is simple, easy to maintain, and long-term use costs are reduced.
Multi-purpose adaptation
Support double or triple pump combinations to meet the needs of complex hydraulic systems.
Compatible with special media such as water-ethylene glycol liquid, and adapts to diverse working conditions.
