12 X 4 Lemco Seal
Mild Steel & Stainless Steel Lemco Seals
Lemco Drawdown Well Seals stop submersible water well pumps from sucking air by forming an airtight seal above the pump. This helps to control drawdown, increase water well production, and retard corrosion buildup in the pumping area. The drawdown factor, which is the difference between the static water level and the pumping water level, becomes a non-issue because the Lemco Drawdown Well Seal forces water to be pumped from the aquifer below, instead of from the static water level above the pump.
In the illustration, the apparent pumping water level is below the pump inlet, but the Lemco Seal keeps the pump submerged in water pumping normally, unaffected by the amount of drawdown outside the well casing.
