Rexroth plunger pumps are generally used in hydraulic transmission systems of machine tools, metallurgy, forging, mining, and lifting machinery, as well as ATLAS drilling rigs. They are particularly widely used in high-power hydraulic transmission systems. If applied to Japanese Kurimoto forging machines, China First Heavy, China Second Heavy, ATLAS drilling machines, Germany's SMSMeer is the most advanced metallurgical rolling equipment manufacturing enterprise, other companies include Sumitomo and Nippon Steel in Japan, and IMS in the United States. For example, it is used for ATLAS drilling rig plunger pumps, Deck crane hydraulic pumps, concrete boom pumps, and static pressure pile machine oil pumps; Aluminum profile extrusion machine oil pump.
