Suction (self-priming) centrifugal pumps. Sewage ejectors. Sump pumps. Sewage pumps. Compressors and vacuum pumps for air ancQiases. Return Line Vacuum Heating Pump Removes air and condensation from the return lines of vacuum steam heating systems; discharges the air to the atmos phere and returns the water to the boiler. Two independent units are combined in a single casing--an air unit and a water unit. Impellers of both are mounted on the same shaft. The pump is bronze fitted throughout. The air unit exhausts air and vapors and delivers these to the atmosphere without back pressure.. The water unit removes condensation and pumps it directly into the boiler. Horsepower is saved, with a proportionate reduction in cost of current. Supplied- either direct connected to standard electric motors, for belt drive, or for steam turbine drive. For continuous or automatic operation against pressures up to 40 lb. Capacities of Jennings Vacuum Heating Pumps k MOTOR R P. Pump Size | A ir Capacity! Cu.

Compactness is secured by making the pump casing a part of the returns tank, and bolting the motor base- to. the tank. The pump can be iristalled in a comer against the wall. Jennings Con densation pumps are furnished in standard sizes with capacities ____ ____________ ranging from 4 to 200 g.p.m. of Coniencation Pump water. For serving up to 150,000 sq. ft. of The last two sizes 'are not of the manifold type. equivalent direct radiation. 754 The Nash Engineering Company Pumps Centrifugal Pump For circulating hot and cold water; boosting city water pressure; handling water in air washing and conditioning; removing condensate from heatingsystems, blow-down from soot blowers and super heaters, exhaust drips from steam ejector air pumps and other auxiliaries; pump ing screen wash water, oil engine jacket water, ash sluicing water, etc. Compact-- motor armature and pump impel ler are mounted on the same shaft: Simplified --no bearings Jennings Centrifugal Pump in pump casing, only one stuffing box. Ac cessible--pump impeller can be removed without breaking pipe connections, or disturbing shaft alignment. Supplied in 1)4. 1/4, 2, 3, 4 and 6 in. sizes for handling up to 2000 g.p.m. Heads up to 300 ft. Suction Sump and Sewage Pumps Sewage Ejector For pumping unscreened sewage or drainage from basements below the street sewer level; handling crude sewage from low level districts; pumping effluent, sludge and other heavy liquids. The Jennings Sew age Ejector is of the pneumatic type. A Nash Hytor Com pressor is used as the , motive power to pump the accumu lated sewage from a pot to. the sewer. Air is compressed, delivered, and used only when required. There are no air Jawing* Pneumatic Sewage Ejector storage tanks, reciprocating air compres sors, or screens. Air valves are avoided. Furnished in standard sizes for handling from 30 to 1500 g.p.m. Heads up to 50 ft. Compressors and "Vacuum Pumps for Air and Gases The Jennings Suction Sump Pump is a self-priming centrifugal pump for handling seepage water and liquids reasonably free from solids. The Suction Sewage Pump is fitted with a non-clog type impeller. Both pumps are mounted entirely above the sump. Only the suction pipe is submerged. Quickly and conveniently accessible, these pumps can be located either near to or removed from the pit. There are only two moving parts, centrifugal impeller and vacuum priming pump rotor. Both rotate without metalto-metal contact in the casing. Both are mounted on the same shaft that carries the rotor of the driving electric motor, making pos sible a single compact as sembly. Furnished in sizes and ca- pacaties to meet all the usual require- Jennings Suction (seif-priming) merits. Setoage Pump The rotor, consisting of a cylindrical hub around the periphery of which are cham bers formed by heavy shrouds cast in tegrally, revolves in an elliptical casing filled with water. As the rotor turns, it carries the water with it. The water under the influence of centrifugal force, follows the contour of the casing, and alternately enters and leaves the rotor _ chambers. As the water recedes from the rotor, air Sectional View of He Nath Hgtor is drawn into Compreuor or Vacuum Pump, the chambers o/ through the in let ports. As the water is forced back into the rotor, the air is.compressed and then discharged through the outlet ports. A separator frees the compressed air of entrained moisture. Supplied in standard sizes for handling up to 5000 cu. ft. of air per minute. For discharge pressures up to 20 lb.; vacuums up to 20 in. of mercury column. ;r Bulletins No. 10.
