Internal Gear Pump

  • Guangdong Lexmua Hydraulic Technology Co., Ltd. is a technical enterprise specializing in sales, maintenance, technical support and after-sales service of hydraulic pumps, valves and motors, leading the development of the hydraulic industry in a new direction.

    The products of gear pump series include NSH Gear Pump, Internal Gear Pump and External Gear Pump, besides gear pump, we also sell Piston Pump.

    We have been engaged in the hydraulic industry for many years. In order to shorten the delivery time of products, we have a large number of hydraulic products. At the same time, we have professionals who are familiar with domestic and foreign hydraulic electromechanical products to solve the problems of imported spare parts for you. Professional and technical personnel with rich practical experience are committed to the development of various high-quality hydraulic products and systems. Consistently insisting on the most favorable price, the most efficient operation and the most thoughtful service, we have won a good reputation in the industry and become a long-term supplier for the introduction of complete sets of equipment and the supply of spare parts in the metallurgical industry.

    We have a lot of products and cannot be displayed on the website one by one. If you do not find a suitable product, you can contact us by email or fill in the form to let us know your needs.

    Next, lexmua will introduce the External Gear Pump:

    Internal gear pump series products include HG and PHG gear pumps, which are high pressure internal gear pumps.

    Features of high pressure internal gear pump

    1. Axial and radial pressure compensation design maintains high volumetric efficiency even at low speeds.

    2. Low noise. using high-strength cast iron and a unique internal noise reduction design, making the noise lower. 

    3. Very low flow and pressure pulsation, and can maintain stable flow and pressure output at low speeds.

    4. High pressure design. The maximum working pressure of high pressure design can reach 35MPa.  

    5. Wide speed range. The speed range is wide, and the maximum speed can reach 3000r/min. 

    6. It is not sensitive to oil pollution and has a long service life. 

    High pressure internal gear pump application

    It can be widely used in industries, such as injection molding machines, shoe machines, die-casting machinery and hydraulic systems in forklifts, etc. It is especially suitable for energy-saving systems driven by servo frequency conversion.
