A charge-driven molecular water pump
Nature Nanotechnology, 2007Understanding and controlling the transport of water across nanochannels is of great importance for designing novel molecular devices, machines and sensors and has wide applications, including the desalination of seawater. Nanopumps driven by electric or magnetic fields can transport ions and magnetic quanta, but water is charge-neutral and has no ...

Single-Stage PV Array Fed Speed Sensorless Vector Control of Induction Motor Drive for Water Pumping
IEEE transactions on industry applications, 2018This paper deals with a single-stage solar powered speed sensorless vector controlled induction motor drive for water pumping system, which is superior to conventional motor drive. The speed is estimated through the estimated stator flux.

Seal Lubrication of an Automotive Water Pump
Tribology, 2006A noisy mechanical seal is a grave problem, especially in water pumps designed for the automotive industry. The noisiness is often caused by dynamic instability (stick-slip behavior), which occurs when the seal lubrication changes from hydrodynamic to mixed.

The Software Design of an Intelligent Water Pump
2017In an effort to increase handpump reliability, the Messiah College Collaboratory and the Department of Computer and Information Science are developing the Intelligent Water Project (IWP) system. IWP measures and reports the functionality of handpumps and volume of water extracted on two-hour intervals daily.
