Hydraulic pumps convert mechanical energy and motion into hydraulic fluid power. The basic idea is very simple: force that is applied at one position is transmitted to another position using an incompressible fluid, like oil, which cannot be compressed but rather is displaced when pressure is applied.A reservoir, a hydraulic cylinder, and a pump make up the three main parts of a KP75A Dump Truck Lifting Gear Pump. Pumping hydraulic fluid from the reservoir into the bottom cavity of the cyli
