A pneumatic Hydraulic Pump is a device that combines the power of compressed air with the principles of hydraulics to generate hydraulic pressure. It is commonly used in various industrial applications where a high amount of force or pressure is required.

The pump consists of a pneumatic motor and a hydraulic pump, which are connected together. The pneumatic motor is powered by compressed air and converts the energy from the air into mechanical motion. This motion is then transferred to the hydraulic pump, which converts it into hydraulic pressure.
The hydraulic pressure generated by the pump can be used to power hydraulic cylinders, motors, or other hydraulic devices. It is commonly used in industries such as automotive, construction, manufacturing, and mining.
One of the advantages of a pneumatic hydraulic pump is its ability to generate high pressure with relatively low energy input. It is also compact in size and can be easily transported and installed. Additionally, it does not produce any emissions or require any fuel, making it environmentally friendly.
However, pneumatic hydraulic pumps can be noisy and require a constant supply of compressed air to operate. They also have limitations in terms of the maximum pressure they can generate.
Overall, a pneumatic hydraulic pump is a versatile and efficient device that combines the benefits of both pneumatic and hydraulic systems. It is widely used in various industries for its ability to generate high pressure and power hydraulic equipment.
Since the fourth quarter of this year, China's copper consumption has experienced a subtle but meaningful shift. On the surface, it may seem like a minor change, but in reality, it reflects a broader transformation in the market. Especially since November, the domestic premium for high-grade copper—brands such as Guiye, Jinchuan, and Copper Crown—has seen varying degrees of increase. Among these, Guiye Copper, which is widely used in East China, currently commands a relatively high price compared to other brands. However, even with its strong position, it still faces pressure from the rising premium trend.
As of the end of December, the discount rate on copper prices has gradually widened, with the best copper premium exceeding 300 RMB. In this short period, the international copper price has reached nearly $8,200 per ton. As one of the world’s largest consumers of copper, China is currently facing a significant demand phase. Although copper demand hasn’t dropped significantly, data from Fubao indicates that the operating rates of copper manufacturers have remained relatively stable. However, the demand for electrolytic copper has declined sharply, and the once-premium copper has now become a commodity.
The decline in high-grade copper prices seems inevitable, while the scrap copper market is showing a different story. Since the fourth quarter, the domestic gap in scrap copper supply has grown larger, with a sharp rise in scrap copper imports. This trend clearly shows an increasing reliance on recycled materials. With the recovery of small traders, competition among scrap copper dealers has intensified, and trade spreads among middlemen have been squeezed to a minimal level. As a result, the supply of scrap copper has become scarce. Many copper mills struggle to acquire it, unlike small workshops that can still manage. Bright-line scrap copper has become highly sought after, and prices fluctuate easily. Especially in the middle of this month, when international copper prices dropped significantly, scrap copper prices hit a new record high. Yet, the market remains tight, and most manufacturers relying on scrap copper have seen their operating rates decline.
This contrast between the good copper and scrap copper markets isn't random. It's not just due to policies promoting a circular economy. In fact, the process of turning scrap copper into finished products is relatively simple and offers better control over profit margins. The main reason lies in the lower cost of electrolytic copper. Currently, many large-scale manufacturers have integrated processes—from recycling scrap copper to producing copper products. Additionally, much of the scrap copper can be used directly after slight processing. Many small workshops in Baoding, Hebei, mainly reprocess scrap copper into copper rods. Wire and cable companies used to buy finished products, but now they can source directly from these workshops. The entire process is straightforward.
In comparison, electrolytic copper lacks this advantage. Its high price also drives demand away. Purchasing electrolytic copper requires melting it down and going through multiple steps to produce copper products. Most of the same processes are involved, but the cost is significantly higher. Therefore, scrap copper has become more attractive, while electrolytic copper has lost some of its appeal. The surge in scrap copper imports has also created substantial pressure on the demand for electrolytic copper. As a result, the unavoidable demand for electrolytic copper leads to price discounts, while the shortage of scrap copper makes it a highly desired commodity.
