A recent survey of installed aluminum reverb furnaces found that most included a pump well only large enough for a properly sized circulation pump. With manufacturing floor space at a premium and furnace prices increasing, it is no surprise that the pump well would be kept to an absolute minimum. High Temperature Systems, Inc. long ago designed a wide range of high efficiency pumps to bring higher circulation rates to reverb furnaces with smaller pump well sizes. These pumps are well known in the industry for providing the highest flow rates with the smallest footprint.
