The Sandvik 77794226 Hydraulic Piston Pump is a genuine OEM replacement component from Sandvik’s 77794-series hydraulic pump range, engineered for reliable high-pressure performance in Sandvik underground mining equipment. As part of the same piston pump family as the 77794205, this pump is built to Sandvik’s precision factory standards and delivers the consistent fluid flow and system pressure that Sandvik Toro LH-series loaders and related underground machines depend on across every operating function.
Axial piston pumps are the highest-performance hydraulic pump type in heavy mining equipment — offering superior volumetric efficiency, greater pressure capacity, and longer service life than gear or vane alternatives. In Sandvik underground loaders, the hydraulic piston pump drives the most demanding circuits on the machine: bucket loading, boom lift and tilt, articulated steering, tramming support, and auxiliary hydraulic functions. A worn or underperforming pump creates cascading effects across all of these systems — reducing bucket fill speed, weakening steering response, causing overheating, and ultimately forcing costly unplanned shutdowns deep underground where every hour of lost production matters most.
The Sandvik 77794226 restores full pump performance as a factory-matched, precision-dimensioned direct replacement. Unlike aftermarket piston pumps that may introduce clearance mismatches, inferior seal materials, or reduced pressure ratings, this genuine OEM part is validated to operate within the exact hydraulic parameters your Sandvik equipment requires from first installation through its full service life.
Designed for efficient installation by qualified mine maintenance personnel, the 77794226 reduces machine downtime whether during a planned maintenance service or an unplanned breakdown event. Its direct OEM compatibility with Sandvik’s hydraulic architecture eliminates the need for adapters, rework, or extended commissioning after fitment.
