In the United States, irrigated agriculture produces about half of the total value of crop sales despite comprising only 17 percent of U.S. cropland. However, irrigated agriculture also represents the largest share of consumptive water use in the nation. Efficient agricultural irrigation helps to balance the incredible value of irrigated agriculture with the need to be conscious of water use.

Protect your pumping system from the damaging effects of water hammer

Posted by AuCom on 12/5/16 9:44 AM

Water hammer has the potential to cause significant damage to pumping systems. Most in the pumping industry have a tale to tell about burst or collapsed pipes, or broken or damaged valves, pressure gauges and even pumps.

Solving the water hammer problem requires either mitigating its effects or preventing its occurrence altogether. To this end, there are a number of solutions to consider when designing a pumping system, including electronic motor control.

Electronic motor control devices such as soft starters and variable frequency drives can be used to control the speed of the pump during starting and stopping. This allows for a more gradual increase or decrease in pump speed, preventing water column separation, flow reversal and sudden check valve closure – a few of the primary causes of water hammer.
