Ningbo Shunchenglong Hydraulic has launched high-performance internal gear pumps to empower the development of multiple industries with precision and efficiency

2025 10/09

 

Recently, the field of hydraulic components has witnessed a technological breakthrough - Ningbo Shunchenglong Hydraulic Co., Ltd. officially released a new generation of high-performance internal gear pumps. This product, with "precise transmission and efficient operation" as its core advantages, has filled the technical gap of domestic medium and high-end internal gear pumps in terms of multi-condition adaptability at one stroke, injecting new impetus into the industrial fluid transmission field.

As a representative innovative product of positive displacement pumps, Shunchenglong's internal gear pump adopts a precise meshing structure design of internal and external gears. By optimizing the gear tooth profile and crescent plate sealing technology, it fundamentally solves the problem of trapped oil in traditional pump bodies, achieving low pulsation and high stability during the transportation process. After authoritative testing, the volumetric efficiency of the product is increased by more than 8% compared with the industry standard, the mechanical loss is reduced by 12%, and it can still maintain stable output under a working pressure of 16MPa, perfectly conforming to the technical positioning of "precision internal gear pump".

"We take the principles of fluid mechanics as the core and carry out triple upgrades on key components." " The company's technical director introduced that this gear pump is made of high-wear-resistant alloy materials to create the friction pairs, and combined with nano-level precision processing technology, the wear resistance of key components has been increased by 50%, and the maintenance cycle has been extended to over 8,000 hours. The innovative low-noise shell structure design reduces the operating noise to below 65dB, creating a new experience of silent operation. At the same time, interfaces for insulation and cooling media are reserved, which can adapt to the transmission requirements of various types of media ranging from -20 ℃ to 80℃ and with viscosities from 0.2 to 1,000,000 CP.

With the core advantage of "precise efficient", this product has achieved full coverage in multiple industries: In the chemical field, it can stably convey high-viscosity media such as resins and coatings; It is suitable for sanitary-level transmission scenarios such as chocolate and syrup in the food and pharmaceutical industries. In the manufacturing of construction machinery and ships, it provides reliable power support for hydraulic power units and heavy oil conveying systems. At present, the products have passed the ISO9001 quality system certification, and the first batch of orders have covered manufacturing-intensive regions such as the Yangtze River Delta and the Pearl River Delta.

 

 

Ningbo Shunchenglong Hydraulic Co., Ltd. has been deeply engaged in the field of hydraulic components for over a decade. The release of this new product is an important implementation of the company's "Technology Empowering Manufacturing" strategy. The general manager of the company stated, "In the future, we will continue to focus on high-pressure and intelligent upgrades, and plan to launch a high-end series with a pressure rating of up to 32MPa, providing more superior hydraulic solutions to support the high-quality development of China's equipment manufacturing industry." ​
