Abstract
In the pumpless system we use the positive displacement concept thus eliminating the problems associated with a typical pump system.
The system uses steam or another gas as the pumping force to move the fluid from the tanks back to the boiler feed system. Impellers,
seals, bearings, packing and expensive controls can be eliminated.
Pumpless systems even allow you to locate these return units in areas of high moisture content, areas that may be subjected to flooding or hazardous locations.
The opportunity exists to replace troublesome pump packages with an efficient, cost-effective condensate return system. This presentation will cover:
1) What is a pumpless system.
2) Ease of retrofit to existing units.
3) Alternative installations and a variety of installation suggestions.
