The utility model relates to the technical field of die pressure heads, in particular to a novel pre-pressing double-side suction pressure head which structurally comprises a pre-pressing assembly and a double-side suction and drainage device, the pre-pressing assembly is connected with the double-side suction and drainage device, and the double-side suction and drainage device comprises a water suction pipe, a pressure head, an air pipe connector, a water suction bottom plate, a water suction hole, a filter screen, a pressure block, a side suction pipe and a connecting pipe. According to the double-side suction pressure head, the vacuum water suction machine controls the three-way valve set to drive the air pipe connector to be switched between water suction and air blowing, so that redundant water in wet pulp is collected into the side suction pipes and the confluence net grooves in the water suction bottom plate through the water suction holes and the connecting pipes under the action of the filter net til
