A7VO is used in aluminum profile extrusion presses.

Product Description: This is the first of its kind in China. A new type of slanted-shaft electro-hydraulic proportional pump can steplessly change the pump’s displacement from 0 to 160 ml/r by adjusting the current of the proportional electromagnet, thereby regulating the system flow rate.

Case Study: Our product and Rexroth’s product were simultaneously tested on the same machine, and the synchronization of the two pumps was excellent. Huaxin’s product was put into operation on January 9, 2017, and disassembled and returned to the test bench in July 2018, achieving a volumetric efficiency of 95%. There was virtually no wear on the core components during sorting, inspection, and measurement.

Test Data: Test data from a third party testing our product: 1700 RPM, 350 bar, total efficiency of 91%, exceeding the national standard requirement of 85%.
