BILGE PUMP Among the nimierous pumps listedby the Swaby Mfg., Co. in the gthedition of their 1921 catalog of Mod-ern Centrifugal Pumping Machinerytliere is a duplex electrical centrifugalbilge pump made in three sizes of 60to 400 gallons per minute capacityfor a pit S feet deep and 5 feet indiameter and in one size of 300 gallonscapacity for a pit 5 feet deep and 6feet in diameter. Special sizes are builton order with capacity to fit any con-ditions or any amount of liquid, sizeof pit, height of delivery, voltageand kind of electric current. The pumps are entirely automaticin action with floats so arranged thatone pump starts operating and if un-able to care for the inflow ds supple-mented by the starting of the secondpump, and it operates until the levelof the Uquid in the catch basin lowers,when the second unit stops automati-cally and the first unit continuespumping until the basin is empty whenit
