Education -  Physics For The Otherwise, Reasonably Well Informed - This tutorial is aimed at those of you who think math is just another four letter word. If you have avoided Physics thus far, maybe this will be your chance to enhance your understanding of the mechanics that governs just about everything we do in life.  The first chapter, Motion & Gravity is available for download on our Education page.

smallnew.gif (926 bytes)Air VS Oil Filled Sewage Pump Motors - This paper takes an honest look at these two popular submersible sewage pump motor designs and compares the advantages and disadvantages of each.

smallnew.gif (926 bytes)Energy Conscious AC Domestic Booster Systems - If you are fortunate enough (or unfortunate, depending upon one's perspective) to live off the electrical grid, efficient energy usage becomes paramount. The water pressure booster can be one of the largest loads on an inverter and, the fact that small pressure pumps and motors are quite inefficient doesn't help the situation. This paper takes a look at the various types of inverter powered pressure boosters, discusses their power requirements, and offers suggestions for reducing inverter loading and inrush current. It is available on our Education page.
