How to Talk to Managers
Most financial decisions of any consequence at your facility are made by managers; Plant Managers, Project Managers, Operations Managers, Financial Managers, etc. If you want to sell your ideas and recommendations to these decision makers, you must learn to talk to them in the financial language they understand. The most common financial tools for evaluating investment options are net present value, NPV, Payback, and internal rate of return, IRR. NPV, Payback, and IRR are all acceptable financial measures to aid in the making of economic decisions. NPV returns a dollar value, Payback returns a duration until investment is recouped, while IRR returns a rate of return value for the investment.

Overhauling or servicing big pumps and valves means dealing with big bores. After installation in the field, valves and pumps often require maintenance to rid the inside diameter (ID) of foreign material, ranging from rust and corrosion to accumulated chemicals and biological matter. Improper cleaning and resurfacing of the IDs of those bores can mean fewer operating hours between servicing as well as degraded performance.

If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.
