For clear water service from 10 to 10,000 gpm, and for heads up to 350 feet, these efficient pumps are widely used for air washers and other air condi tioning units. Each pump is hydraulically bal anced (water enters each side of impeller with equal pressure and volume), which contributes to the smooth operation and efficiency, as do simply .formed water passages in the casing. BULLE TIN 955-N. AUTOMATIC SUMP PUMPS. Compact units, shipped complete, ready for quick installation. Ball bearing thrust carries weight of moving parts. Shaft is entirely enclosed--completely protected from sump water and from fouling with waste or stringy matter flowing into sump pit. All parts are readily accessible. BULLETIN 963-F. CLOSE-COUPLED SINGLE SUCTION PUMPS. Extremely compact design permits installation vertically or horizontally. Available with either threaded or flanged connections. Suited to hand ling hot water with low submergence. Impeller overhung on motor shaft assures permanent align ment. BULLETIN 975-C. SELF-PRIMING SINGLE AND DOUBLE SUC TION PUMPS. Positive prime is obtained al most instantly when pump is started, without use of foot-valve. All parts are accessible, and above liquid to be pumped. Can be automatically op erated in remote locations.

Fig. D-9900--Duplex "Condo-Vacs" with Duplex Double Automatic Control CLOSE-COUPLED PUMPS Boiler Feed, Circulating, Tank Filling, Water Supply 'Capacities range from 3 to 600 Gpm against heads up to 189 ft. Motors from 1 to 20 hp. Discharge 1 to 3 in. Closed and open type impellers. Bulletin 108. "CONDO-VAC" Return Line Vacuum and Boiler Feed Pump for Heating Systems No vacuum on stuffing boxes, ample clearance in rotating member. It costs less to operate a "Condo-Vac." "CondoVac" reduces corrosion in piping and boiler to ^minimum--because pump does not take in air from atmosphere and en tirely eliminates all air coming back from system. "Condo-Vac" is quiet, has a low inlet, entirely automatic, fool-proof, easy to maintain. Askfor Bulletin 270.

Built in either single or duplex units. Duplex units are alternated in their operation by the Automatic Alternator. Complete data in Bulletin 250. . VERTICAL CONDENSATION PUMPS for Low and Medium Pressure for Sys tems from-500 to 100,000 Sq Ft Radiation iThe vertical condensation pump is designed to receive re turns from lowest radiation. The receiver is placed under ground--an ordinary hole sufficing if necessary--and requires v-'asoo very little floor space. Unit is shipped complete, easy to Vertical install, assembled so as to prevent steam leaks. Special bear- Condenings will stand up under hot water for several years. A special float mechanism is guaranteed not to leak or stick in stuffing box. Complete data and description in Bulletins 245,253 and 255. 1403
