Bohang Advantage: Industrial presses require 24/7 reliability. Our A4VSO pumps are manufactured with the exact processing time required for heavy-duty swashplate bearings. Every unit is tested by our senior engineers on high-pressure benches to guarantee 100% volumetric efficiency for industrial cycles.
1. Modular Control (A4VSO): Compatible with DFR, DR, and DFE controls for precise pressure/flow management.
2. Long Fatigue Life: Swashplate bearings designed for continuous high-pressure cycles.
3. Built for the toughest jobs. The A4VSO (Open Circuit) is perfect for industrial presses.
FAQ
Q: Why is the A4VSO preferred for industrial presses and steel mills?
A: The A4VSO is built for continuous high-pressure operation. Its large swashplate bearings and hydrostatic lubrication allow it to run 24/7 in industrial environments. It also supports extremely complex controls like DFE1 (Electronic Pressure/Flow Control) for high-precision manufacturing.
Q: What maintenance is required for the swashplate bearing?
A: Our A4VSO features a long-life bearing design. To maximize service life, we recommend maintaining oil filtration at ISO 18/16/13 level and ensuring the case drain temperature stays below 90°C.
Q: What is the maximum peak pressure for the A4VSO industrial pump?
A: Our A4VSO series is designed for a nominal pressure of 350 bar and a peak pressure of 400 bar, perfectly suited for heavy industrial presses and steel mill equipment.
Our Strategic Advantages
1. Decades of Specialized Expertise (Since 2008)
The Message: We aren't just a manufacturer; we are hydraulic pioneers. With nearly 20 years of dedicated focus on the Rexroth technical system, Foshan Bohang understands every internal tolerance and metallurgical requirement of axial piston units.
2. Premium Imported Raw Materials
The Message: Quality begins with the source. To match Rexroth’s durability, we exclusively use high-grade imported raw materials. From specialized alloy steels for cylinders and pistons to premium NBR/FKM (Viton) seal kits, our material selection ensures our products thrive in extreme high-pressure and high-temperature environments.
3. Standardized "Rexroth-Level" Manufacturing Process
The Message: We don't take shortcuts. Our production lines follow the exact standard operating procedures (SOP) and processing times as Rexroth. Each component undergoes precise heat treatment, nitrogenation, and grinding to ensure that our replacement units are 100% interchangeable and functionally identical to the original.
4. 100% Engineer-Verified Performance Testing
The Message: "Zero-Defect" is our goal. Before leaving the factory, every single unit is personally tested by our senior engineers on high-precision digital test benches. We verify volumetric efficiency, mechanical noise, and leakage rates under full load to guarantee "Plug-and-Play" reliability for your machinery.
5. The Best "Drop-in" Alternative in China
The Message: Foshan Bohang is committed to being the top-tier Chinese alternative to Rexroth. We bridge the gap between high-priced originals and low-quality aftermarket parts. Our mission is to provide global customers with the most cost-effective, high-performance axial piston pumps and motors that match the original installation dimensions perfectly.
