Grand Boulevard St. Paul, Minn., 308 Metropolitan Building Monadnock Building Economy Pumps and Receivers Type CSS Economy pumps and receivers are made in a variety of sizes and types for every pressure and capacity condition. 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 case 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 ana outboard ring oiling or radial ball-bearing. The most popular of all Economy pumps and receivers; a thoroughly dependable unit at aTmyopdeerCatSeMpr--iceA. 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 Wz 7 7V4 8 Wi 9 Wz 10 Capacity in Sq. Ft Direct C. I.

Pumps Economy Underground Pumps and Receivers Type CU Underground pumps and receivers are used where returns are so low that a pit would be required for a horizontal pump. The underground unit consists of a special vertical bronze fitted pump having renewable bearings throughout and a cast iron receiver which is permanently resistant to corrosion and special type of float mechanism is used with swivel type stuffing box. When necessary to use ah underground pump on high pressure job the standard low pressure unit may be used discharging into the receiver of a high pressure horizontal pump. Our engineering department will be pleased to work out details of such in stallations. See Bulletin No. 405. Type CU. Underground Pumps and Receivers Type CU Capacity Sq. Ft HJ\. 10 lb.

(smaller sizes are equipped with bronze fitted solid shell pumps). All parts of the pump are accessible without breaking pipe connections or dis mantling the unit. The float control is located close to the floor so that a close water line may be maintained when operating as a gravity system. The boiler feed arrangement is positive and simple. The entire apparatus is shipped completely assembled and wired in accor dance with the National Electric Code. In addition to the single pump duplex units are furnished which consist of single tank, two pumps and motors. Tests with calibrated orifices are made on all pumps before shipment. Standard pumps are designed for operation against 20 lb. pressure but reasonably prompt delivery can be made on units for discharge pressure up to 150 lb. See Bulletin No. 409.

In these pumps the head per stage has been limited to a figure at which high efficiency and long life is obtained. Distinctive features of Economy horizontally split design are solid one piece bronze dia phragms, the volute in every stage and the hydraulic balanc ing device. The table shows maximum head at 1750 r.p.rn. Higher pressures are obtained with 3600 revolution units. Specifications are given in Bulletin No. 406. Type M Economy Double Suction Centrifugal Pump Economy general service single stage centrifugals are made in a complete range of capacities up to 3500 G.P.M. They are widely used for general water supply, hot water circulation, brine circula tion, air washing service, etc. They embody the newest hydraulic developments which give them an unusually high efficiency over a broad range. The mechanical design is simple and rugged. Descrip tion and complete table is given in Bulletin No. 408.
