Linear-motor driven plunger pumps are most efficient at transforming mechanical energy to hydraulic work in low-producing and highly deviated wells. Linear-motor driven plunger pumps (LMDPP) are most ...

Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

Industrial processes across the globe require pumps to operate reliably and efficiently. The latest pump designs and coating technologies offer significant improvements in the long term performance of ...

Boiler feed pumps (BFPs) play a major role in the capacity and heat rate of a power-generating unit. As such, they merit routine performance testing to assess their condition and trend deficiencies to ...

Traditional sucker rod pumps (SRP) use a single traveling valve, but recent double traveling valve innovations have improved SRP performance and efficiency in field applications with double traveling ...
