TSMOUTH STEEL, CO. Executive OfficesWHEELING,W. VA. Operating and Sales Dept.PORTSMOUTH,OHIO THE MOST EFFICIENTRAILROAD PUMP is the centrifugal for the cause that it raisesmore water with much less power and requires lessattention than any other style of pump. American 99 Centrifugal PUMPS provide 25 to 33percent much more water with thesame energy than old style centrifugals. The purpose is the impeller is accurately machined tothe casing- with a excellent reduce-off at the outlet, making- itimpossible for water to pass the discharge pipe and berepumped, and there is no sudden change of directionof the water in passing thru the pump. The single stage pump operates against heads up to125 feet, the two-stage up to 250 feet, the four-stage up to500 feet, and can be operated in any location exactly where aduplex steam pump can be installed,at significantly less initial price and less expense ofmaintenance.

ereis full continuity of insulation throughout every phase of the winding.The star point is very carefully spliced and vulcanized in a special mould. Inthis type of machine the cost-free ends of each phase are brought out througha stuffing-box on the motor-frame for a length of about 50 feet, and thereterminate in a three-pole watertight coupling, to which reference willbe created once again. The extended cables are protected by armoured rubberhose. The overhangs of the coils are clamped securely to the motor-physique. The iron core-plates of each stator and rotor are treated with aspecial varnish, each plate becoming passed through a machine resemblinga domestic mangle, the rollers of which revolve in the liquid. By thismeans an even layer of varnish of mimimum thickness is applied to eachplate, hence effectively sealing the joints in the assembled core.

The brass cylinderthrough which the water passes is offered with a large number ofopenings about f inch in length circumferentially and about 20 mills(-020 inch) in width axially. These openings lead into an annularchamber of ample dimensions surrounding the brass cylinder, in whichchamber the water moves at a quite low velocity.
