Lemco Seals stop submersible pumps from sucking air by forming an airtight seal above the pump to keep it submerged in water. This helps Control drawdown and increase well production. It also protects the submersible pump by providing an air and contamination barrier.

If you’re a water well driller or pump installer having problems with submersible pumps sucking air, then you’ve come to the right place. The Lemco Seal was invented by a well driller who was having trouble with excessive drawdown causing submersible pump motors to burn out. The Lemco Seal controls drawdown by making an airtight seal above the pump. This forces it to draw from the aquifer below instead of lowering the water level inside the well during the pumping cycle. Because it makes an airtight seal, it can also increase well production, which makes it ideal for low water level and slow producing wells.
