A mineral processing operation has a cooling water system with two 335-kW (450-hp) pumps to supply water. The cooling requirements over time were drastically reduced so the pressure and flow of operation were much lower than the initial design. Two 30-kW (40-hp) pumps were installed with VFD control to better fit the system requirements and reduce operation costs.

A new air-conditioning system was required to meet variable chilled water demand. Three system configurations were evaluated: A single pump with a bypass line, a single pump with a flow control valve, a three-pump system with variable frequency drives (VFDs).

Paint and coatings manufacture requires the safe and efficient handling and transfer of abrasive liquids, such as titanium dioxide (TiO2), which is an additive used to make latex. When a paint manufacturer began experiencing a shortened diaphragm lifespan in its Air-Operated Double-Diaphragm Pumps (AODD Pumps) Pumps that were tasked with handling TiO2, it was recommended that they switch to Integral Piston Diaphragm (IPD) models. Since making the change, the service life of the diaphragms can now be measured in years rather than months, resulting in reduced downtime and an optimized paint-manufacturing operation.

For a process requiring a charge of liquid at 210°C, an alternative, high-temperature seal is considered to reduce the cost of the system. This high-temperature seal eliminates the need for a cooling system and a reheating system. The high-temperature seal results in the installation being paid off in two months.

A detailed review of ASME and API pressure-testing requirements was conducted to assess two acceptable procedures: removing pump casing priming valves prior to testing or leaving these valves installed and fully open. The engineering team evaluated risks, compliance considerations, and potential waste associated with scrapping valves unnecessarily. The updated procedure, which includes leaving the pump casing priming valve in place and applying a pressure-rated plug at the outlet, was successfully implemented and validated across manufacturing applications involving water and seawater. Consequences of not revising the procedure included unnecessary component disposal, increased cost, and reduced verification of final assembly integrity.Â

In a water distribution system, constant pressure was being maintained using pressure relief valves (PRVs), which divert excess water back to storage tanks. While effective, this method forces pumps to operate at full load continuously, leading to energy inefficiencies and increased wear. This case study explores the implementation of a Variable Frequency Drive (VFD) system, integrated with a pressure transducer, to maintain consistent pressure dynamically resulting in significant energy savings and a rapid return on investment. The installation resulted in payback in just 6 months.

When two critical motors—rated at 18.5 kW (25 hp) and 90 kW (120 hp)—burned out, the maintenance team faced a common decision: rewind or replace. While rewinding is often less expensive upfront, it can result in reduced efficiency. This case study presents a comparative cost analysis, revealing that motor replacement offers greater long-term value, with a break-even point reached within two years.
