Excavator Hydraulic Pump Block

The efficiency of earthmoving machinery is won or lost in the cylinder bores of the Excavator Hydraulic Pump Block. We specialize in manufacturing pump blocks that feature mirror-like surface finishes (Ra 0.2-0.4 μm) to minimize friction and heat generation. By utilizing our 25+ years of heat treatment expertise, every Excavator Hydraulic Pump Block we produce achieves a specific surface hardness that extends the service life of the entire pump assembly by up to 40% compared to standard castings. Our background in supporting Sany Heavy Industry's most demanding projects means we understand exactly how to prevent thermal expansion and internal leakage under high-cycle workloads.

Working with our team means choosing a supplier that values communication as much as precision. For every order of an Excavator Hydraulic Pump Block, we proactively provide production updates, including real-time photos and videos of the machining and heat treatment process. We operate a 27,000-square-meter workshop in Jingshan, ensuring we have the capacity to deliver standard models within 10-15 days. We pride ourselves on the motto: "People-centric and scientifically managed." Our R&D team of 7 technicians ensures that even the most complex internal oil porting is executed flawlessly. With ISO 9001 and ISO 14000 certifications, we guarantee that your hydraulic components meet the highest global standards for both performance and environmental compliance.
