The present line is the result of a long study and improvement by this Company which was one of the pioneers in the manufacture of Electric pumps and receivers. The use of these pumps to improve circulation with a reduction in boiler pressure usually results in large fuel economies. The savings are particularly striking in the case of medium pressure plants where it' is desired to work at low pressure during dull periods of'the day. The table below gives a partial list of sizes which are available in either solid shell or horizontally split mm* designs. Complete specifications and descriptions will be found in Bulletin No. 405. All Economy pumps are substantially mounted on cast iron bases with machined pads. Either cast iron or steel receivers are used. The automatic control is assembled as a unit and is easily accessible for inspection at all times. The most important features of individual standard designs are given below. Type CSS--A single suction solid shell unit with oil-less stand bearing and outboard ring oiling or radial ball bearing. The most popular of all Economy pumps and receivers; a thoroughly dependable unit at a moderate price. Type CSM--A double suction horizontal split case unit with enclosed bronze impeller with ring oiling bearings. This unit has been designed for use where the service is unusually severe as where equip ment of the highest grade is desired. . Type CST--Multi-Stage Pumps for pressures above 40 lb. They are bronze fitted with ring oiling bearing at the driving end and radial ball bearing at the outboard end. No. of Unit 6 6>/2 7 7Vi 8 8V2 9 9!/2 10 Capacity in Sq. Ft. Direct C. I.

The underground pump consists of special vertical pump which b bronze fitted and controlled by a special mechanism which prevents binding and sticking of float rod. Lower bearing b of the oil-less type which has given such excellent service in these pumps for the last twelve years. When necessary to use an underground pump on high pressure jobs we recommend the use of a low pressure underground pump discharging into the receiver of a high premure horizontal pump. Our engineering department will be pleased to work out the details of such installations. Capacity Sq. Ft. Hp., 101b. Discharge Pressure 2000 y. 3500 5000 8 7500 A Type CU.
