VFD optimises hospitals water supply

Requiring a constant and reliable water supply, a Middle East hospital is using Invertek variable frequency drives with Optiflow technology as a solution.

 
Simulation of valve operation in a down-hole pump

A finite element model of the valves in a down-hole pump was developed.

 

WEFTEC is the largest wastewater trade show in the US. In this show review, Michelle Segrest gives her impressions from the showroom floor.

 

Vertical gear motors from ABB have been chosen to power the enormous pumps installed in a new flood control project in New Orleans.

 

The effect of flowrate, particle size and pump speed on the erosion of a pump casing was studied.

 

This study proposes a particular assembly of Classification and Regression Trees (CART) for the detection of faults in a pumping system.

 

This study describes a statistical approach for the assessment of discrete models for gear pump efficiency prediction.

 

Disc pumps are used for difficult pumping applications such as pumping of high suspension solids and abrasives, and viscous fluids.

 

This research proposes an optimized photovoltaic based water irrigation system designed to protect Mauritania’s oases.

 

Two types of sliding vane vacuum pumps were compared through numerical simulations.

 

This study built a multi-objective mixed-integer linear programming model to minimize the number of pump stop/restarts and reduce pump running costs.

 

Here we look at the role of one engineer in dredging projects around the world.

 

It was found that the pressure pulsation induced by the floor-attached vortex fluctuates periodically with time.

 

Different approaches were studied in order to find a robust, yet accurate, pump model suitable for CFD based methods.

 

This paper proposes a model for optimizing irrigation water allocation in a complex multi-stage pumping-water irrigation system.
