Hoffman Specialty Co., Inc. Specialties, Heating and Pumps HOFFMAN-ECONOMY RETURN LINE VACUUM PUMPS The jet type vacuum producer used in these pumps is one of the simpiest and best known methods for exhausting air and vapors. It has no moving parts and avoids close clearances so that loss of efficiency, due to wear, is reduced to a minimum. Pumps will handle extremely hot water and are smooth and quiet in operation. All units of 16,000 sq. ft. and over have horizontal split case pumps with enclosed, double suction, bronze impellers.

Specialties, Heating and Pumps HOFFMAN-ECONOMY VERTICAL UNDERGROUND COND. PUMP Where return lines are located below the floor, or otherwise too low for Horizontal Condensation Pumps, the Vertical Underground Pump should be used. No concrete pit is required as receiver is of heavy cast iron suitable for underground use. Ball bearing pump shaft is mounted in dust proof housing. Lower bearing is self lubricating and renewable without removing impeller from shaft or dismantling pump. Can be furnished in duplex unit or for high pressure by addition of horizontal booster pump. Float switch mechanism same as in Horizontal pumps. Completely assembled and. wired, ready for installation. Capacity Table --Vertical Underground Condensation Pumps Pump No. U30 U-50 060 Pump RP. .

These units are low in cost but are not as quiet as Centrifugal type, due to the slight pulsation at end of stroke and chain drive. Standard sizes range from 1,000 to 10,000 sq. ft. of radiation with discharge pressures of 50 and 100 lb. in each size. Capacity Table--Reciprocating Pumps Pump No. Capacity Sq. Ft.

By drawing up colder air from the floor level, warming it and then distributing it directly in the "living zone" a large percentage of the air is constantly recirculated, confining it to the zone of usefulness and eliminating waste due to overheating the upper, or unoccupied portion of the room.
