Pumps don't just push fluids, they can also direct pressurized air from one spot to another. Whatever substance is being pumped, the following suggestions can reduce the costs involved:
Eliminate leaks in compressed air lines and valves. Up to 20% of the work output of a compressor is sometimes needed to make up for losses from air leaks. A General Motors assembly plant in Flint, Michigan, for example, reduced its energy needs by around 8% after, in part, decommissioning unused air supplysystems and ensuring that those that remained worked properly. (Energy Matters, ‘Why Your Plant Should Be Efficient', US Department of Energy)
Eliminate leaks in steam pipes and fittings. A leak in a steam line can result in higher steam production requirements to compensate for what is lost. In addition, leaking condensate return lines bring back less condensate to their boiler, thereby forcing the boiler to use more energy to heat up replacement water. In 2006, an Eastman Kodak manufacturing plant in Rochester, New York, reduced its annual natural gas needs by 11% after improving and modifying its feed-water heat recovery system – a move that was accomplished at virtually no cost.

Insulate pipes and heating equipment to reduce heat loss. All pipes that transfer heated fluids or gases from one process to another should be well insulated.
Consider using industrial heat pumps (IHPs). IHPs use heat from heat producing processes to supplement other industrial heating processes or in preheating procedures.
