A sludge supplying equipment using a plurality of pumps is provided to discharge sludge stored in a storage tank from the storage tank using pressure generated by a simultaneous operation of a low pressure pump and a high pressure pump, and effectively increase a transfer amount of sludge and consistently flow the sludge into a filter press by the operation of the low pressure pump and the high pressure pump. In a filter press(10) into which sludge flown in from a sludge tank(11) is injected to separate compressed cake from the dewatered sludge after compressing sludge, thereby dewatering the sludge, a sludge supplying equipment using a plurality of pumps comprises a low pressure pump(12) and a high pressure pump(13) as sludge supply means formed between the sludge tank and the filter press and connected to a separation pipe(21) and a discharge pipe(22) having predetermined diameters respectively, wherein sludge is consistently supplied to filtering plates(14) of the filter press under the conditions that the low press pump is maintained to a pressure of 3 to 5 kg/cm^2, and the high pressure pump is maintained to a pressure of 7 to 12 kg/cm^2.
