A hydraulic jack including a frame and a pump connected to the frame. The pump includes a rod, a housing, a piston and a plurality of valves. The rod has a cross-sectional area. The housing has an end through which the rod slides. The piston is associated with said rod, with the piston establishing a rod side chamber and a piston side chamber within the housing. The piston having a cross-sectional area. The plurality of valves each are fluidly connected to the rod side chamber and/or the piston side chamber. The piston, the rod and the valves are arranged to provide a first hydraulic fluid flow associated with the cross-sectional area of the piston until a predetermined pressure is reached and a second hydraulic fluid flow associated with the cross-sectional area of the rod after the predetermined pressure is reached.
