It is a dual\u2011section axial piston pump with a separate pilot gear pump, factory\u2011engineered by Kawasaki specifically for 6\u20138\u2011ton Hitachi mini excavators. Your machine originally left the factory with this exact hydraulic architecture \u2013 not an aftermarket compromise, not a remanufactured core. This is a brand\u2011new, genuine pump built to the same tolerances and tested to the same standards as the unit that powered your ZAX70-5A or ZAX70-5G on day one.<\/span><\/p>\n<h3><span class=\"\">1.

On the ZX70-5G, this K7SP36 unit is connected in series with a K7V28 pump. Together, they split the excavator\u2019s hydraulic demand between high\u2011flow working circuits (boom, arm, bucket) and high\u2011pressure travel\/swing circuits \u2013 without robbing power from one function to feed another.<\/span><\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Genuine Hitachi OEM specification<\/span><\/strong><span class=\"\">\u00a0\u2013 OEM part number YD00013056 for the K7SP36 series pump.

On the ZX70-5G, this unit is connected in series with a K7V28 pump, collectively constituting the hydraulic pump assembly.
