Product Description

PGE100 - 100 - LCI1 - N - 3700
Hydac PGE100 - 100 - LCI1 - N - 3700 is a quantitative external gear pump belonging to the PGE100 series. It is designed with a compact structure and reliable performance, and is widely used in open-loop hydraulic systems. The following is a detailed overview combining the model decoding, core performance, structural characteristics and typical applications of the PGE100 series:
Core Performance Parameters
  • Operating pressure: The rated working pressure is 130 bar, and the peak pressure can reach 170 bar. This pressure level can well adapt to the pressure demand of conventional industrial open-loop hydraulic systems, and the peak pressure performance can cope with the instantaneous pressure impact of the system, protecting the pump body from damage due to sudden pressure surges.
  • Speed limit: The maximum speed can reach 3500 rpm. It is compatible with the speed output of most industrial drive motors, and it is easy to match with various transmission mechanisms, ensuring the continuity of oil supply under high-speed operation.
  • Viscosity adaptation: Referring to the general viscosity requirements of the PGE series, it is suitable for hydraulic oil with a viscosity of 16 - 200 cSt. It can adapt to the viscosity change of hydraulic oil in different temperature environments, and maintain stable oil output efficiency without being greatly affected by oil viscosity fluctuations.
Structural and Functional Characteristics
  • Stable and durable structure: It adopts precision-processed meshing gears and wear-resistant pump body materials. The unique gear shape and gap adjustment mechanism ensure the stability of the pump during high-pressure and high-speed operation, and prolong the service life of the pump body. Under correct use and maintenance, it can realize long-term continuous operation.
  • Low-noise operation: The PGE100 series optimizes the gear meshing design. Compared with similar products, it reduces the noise generated during operation, which is more suitable for industrial environments with high requirements for noise control.
  • Easy maintenance: The overall structure of the pump is simple. The standardized flange and shaft design not only facilitates installation, but also makes the disassembly and replacement of vulnerable parts such as internal gears and seals more convenient, reducing the downtime and maintenance cost of the hydraulic system.
Typical Application Scenarios
This model is suitable for small-flow, medium-and low-pressure open-loop hydraulic systems. It is widely used in fields such as machine tools, light industrial machinery, small construction machinery, and automatic production line hydraulic stations. It can provide stable hydraulic power for components such as hydraulic cylinders and hydraulic motors. For example, it can be used for the power output of the clamping mechanism of CNC machine tools and the lifting mechanism of small lifting equipment. It is also applicable to the hydraulic transmission system of auxiliary equipment in the iron and steel, automobile and port industries.

Model Segment Corresponding Meaning
PGE Product series: HYDAC external gear pump, which realizes liquid delivery and pressurization by the change and movement of the working volume formed between the pump cylinder and the meshing gears.
100 Size 0: It is the smallest size in the PGE series. The displacement range of this size series is 0.25 - 2.00 cm³/rev, which is suitable for small-flow hydraulic working conditions.
100 Displacement: Corresponding to a displacement of 1.0 cm³/rev, it determines the volume of hydraulic oil output by the pump per revolution, which is the core indicator for matching the flow demand of the hydraulic system.
LCI1 Structural configuration: It represents specific configurations such as the pump's flange, shaft type and seal. Referring to the same series of product specifications, it is usually matched with a standardized installation structure. It may be equipped with an NBR seal and a corresponding mounting flange, which is convenient for stable assembly with the hydraulic system.
N Standard configuration: It means the basic functional version without special customized functions, such as special medium corrosion-resistant modification, etc., meeting the conventional industrial hydraulic application requirements.
3700 Fixed product code: It is the standard code for the product configuration batch, which is used to distinguish different derivative configurations in the same series and is convenient for factory production management and after-sales traceability.
