When choosing a pump for a given application, there are many factors to consider. The system's parameters dictate the pump needed, so the trick to ensuring a maintenance-free design is determining which parameters affect reliability.
With the handling of sludge – often the most problematic area in the wastewater treatment process – two wastewater treatment facilities in Scotland and Germany installed non-clogging pumps for greater efficiencies and savings in maintenance.
The Jordan, Knauff & Company (JKC) Valve Stock Index was up 1 percent over the last 12 months, below the broader S&P 500 Index which was up 5.8 percent. The JKC Pump Stock Index was up 10.8 percent for the same time period.
Overhauling or servicing big pumps and valves means dealing with big bores. After installation in the field, valves and pumps often require maintenance to rid the inside diameter (ID) of foreign material, ranging from rust and corrosion to accumulated chemicals and biological matter. Improper cleaning and resurfacing of the IDs of those bores can mean fewer operating hours between servicing as well as degraded performance.

When I first discovered the affinity laws, I was impressed by their simplicity, versatility, and power. For me, they held a certain allure. I believed I could use these three simple relationships to solve any pump problem:
To state that 2009 was a turbulent year for the pump industry is a substantial understatement.
