Pump Head Body Forgings Built for Demanding High-Pressure Applications
In high-pressure pumping equipment, the pump head body is much more than a housing. It contains the fluid under extreme pressure, supports internal sealing systems, and provides the foundation for reliable pump performance. Any weakness in material quality or machining accuracy can shorten service life or increase maintenance costs.
For this reason, Zhongyuan Heavy Forging manufactures pump head bodies from forged alloy steel rather than ordinary cast materials whenever high strength and long-term durability are required.
Our products are widely supplied for oil & gas equipment, pressure pumping systems, petrochemical machinery, hydraulic installations, mining operations and other heavy-duty industrial applications where strength cannot be compromised.
Forging Makes the Difference
A pump head body experiences repeated pressure cycles throughout its operating life. Internal stress, vibration and pressure fluctuations continuously challenge the material.
Forging helps overcome many of these challenges.
During the forging process, the steel grain flows naturally with the shape of the component instead of remaining randomly distributed as in conventional castings.
These enhancements directly translate into higher mechanical strength and fatigue resistance, making the structure far more dependable. In practice, this means the component holds its shape and performs safely even after years of heavy use, without the creeping deformation cheaper castings often suffer from.
There's no such thing as a one-size-fits-all solution here. We match the alloy to the job. For high-stress applications, we typically work with grades like 25Cr2Ni4MoV or 30CrNi3MoV.
Rushing at any stage will eventually cause even the best metal to deform or become brittle at the times when it is most needed. Because of that, we start off by identifying and discarding any bad raw materials upon arrival. If it's a base material, and it's low in quality, it's just a waste of time and money to go through the other processes.
Large-scale forging is what Zhongyuan does as a full-time job and we've been doing it for many years by now. Our premises include heavy hammers, large furnaces, precision CNC machines, and state-of-the-art inspection equipment. For you, this means fewer suppliers to deal with, quicker feedback, and more consistent product. In the end, each pump head we deliver is working toward one common target of not failing under the extreme pressure, the high loads, and the extended time.
About Us
In addition, Henan Zhongyuan Heavy Forging Co., Ltd. (HHF) has built an in-depth understanding and rich experience of nearly twenty years in the field of heavy-duty forging by accumulating technical know-how since it was founded in 2006.
The factory's floor space totals about 150 mu (equal to about 100,000 square meters). Besides three extensive open-die forging production lines with 10,000-ton hydraulic presses as core equipment, two state-of-the-art die forging production lines also work, and they are accompanied by large-capacity CNC machining centres, the necessary heat treatment lines, and the top-ranking national class II laboratory. The annual production capacity is up to 50,000 tons of large open-die and dies forgings (including pieces that single weights are over 30 tons).
Approximately 500 people work for the company at the moment, among them, at least 50 people are the R&D team that concentrates on new technologies, materials, and new processes development. The R&D team is composed of senior engineers and technologists.
Among the quality management system supports are numerous certifications, including the American API Q1 standard, API 7-1 licensing for drill stabilizers and drill collars, CSSC system approval, and international recognition for example ISO 9001:2008 and ISO/TS 29001.
For years, the company has been supplying forged parts as the primary material to big companies at home as well as internationally. Different industries such as energy (wind, hydro, and thermal power), mining machines, shipbuilding, and heavy equipment are the company’s customers. Some big Chinese companies like CITIC Heavy Industries, China First Heavy Industries, Taiyuan Heavy Industry, Goldwind, and Envision Energy are the customers, and there are also clients overseas, like Joy Global, Komatsu, and Caterpillar.
Company exportation of these products continues and it goes beyond 20 countries and regions. The major buyers are Germany, the USA, Australia, India, Russia, Brazil, South Africa, South Korea, and Japan.
