LAKOS Video Shows Growers How to Keep Sandy Wells Productive
Without Damage to Pumps and System Components


(OMAHA, Neb.) – November 2015 – Drought-stressed farm water supplies are prompting growers look to older wells for their crop water needs. While many old wells have sand contamination issues, a new video from LAKOS, a Lindsay company, shows growers that such wells can still be productive without damaging pumps and system components. 

Pumping sandy water exposes a pump’s impellers and bearings to significant wear, which reduces the pump’s efficiency and forces longer operating cycles in order to deliver the required water. As a result, it takes more energy to deliver the water, which leads to higher pumping costs. Because prematurely worn pumps also must be repaired and/or replaced more often, there also are extra expenses as well as a significant risk to crops during the critical growing season.

The LAKOS video shows how an in-well sand separator keeps a sandy well productive. This device prevents well sand from damaging the pump and prevents the sand from entering into the irrigation system. Removing sand from the water before it gets into the pump significantly extends pump life. This also relieves the burden of excessive sand on downstream equipment, allowing for the use of more efficient water systems without clogging, fouling, plugging and/or abrasive wear.

Without filters or screens, the downhole sand separator employs centrifugal action as the energy of pumped water helps separate troublesome sand passing from the water as it flows through the separator into the pump intake. A no-maintenance flapper valve controls the discharge of sand deep into the well, and the natural flow of water in an aquifer helps control sand build-up at the bottom of the well.
