The Sandvik 55059183 Tandem Hydraulic Pump is a genuine OEM replacement component from Sandvik’s 55059-series spare parts range, engineered to restore full dual-circuit hydraulic performance in Sandvik mining, drilling, and screening equipment. Unlike a standard single-section pump, a tandem pump combines two independent pump sections on one common drive shaft — allowing a single driven unit to simultaneously supply two separate hydraulic circuits at their required pressures and flow rates.
This dual-circuit architecture is used in Sandvik equipment where space, weight, and drive efficiency are critical — a single tandem pump replaces what would otherwise require two separate pump units, reducing complexity, minimising installation space, and eliminating the need for an additional power take-off point. In practice, this means the 55059183 may simultaneously power a primary working circuit (such as drill feed, boom actuation, or crushing) alongside a secondary circuit (such as steering, tramming, lubrication, or auxiliary functions) — all from one compact, efficiently driven unit.
When a tandem pump begins to fail, the effects are rarely isolated to one circuit. Pressure drop, internal cross-leakage between sections, and uneven volumetric output can simultaneously degrade multiple machine functions — often making fault diagnosis more complex and machine response erratic across several systems at once. The Sandvik 55059183 eliminates this uncertainty by providing a factory-matched, fully balanced OEM replacement that restores correct pressure and flow to both circuits immediately upon installation.
Unlike aftermarket tandem pumps that may introduce mismatched section displacements, inferior seal materials, or unequal output ratings between sections, this genuine Sandvik OEM part is validated to perform within the exact dual-circuit specifications your equipment requires — protecting both the immediate hydraulic system and the downstream components that depend on it.
