These are some of the questions we have been asked over the years about the Lemco Drawdown Well Seal. Q - What is the Lemco Seal made of?
A - The Lemco Seal is made of mild steel and pliable rubber. Q - What are the specs on the rubber?
A - The rubber is a buna synthetic rubber.
Q - Why is the seal larger than the well, when I measure the outside diameter?
A - The rubber has to fold up all the way around before it will go down in the well.
Q - Are some of the Lemco Seals made of brass? A - The Seals are plated with a zinc-yellow coating for its protective and decorative properties and this gives them a gold color.
Q - Do you offer seals in stainless steel?
A - Yes, we do.
Q - Is it hard to push the seal down into the well?
A - Some drillers wet the well casing ahead of the seal, then put water on top of the seal to help push it down.
Q - Is it hard to pull the seal out when the well needs repairing?
A - You will need some type of lifting device to pull it out.
Q - Do you have replacement rubbers, when the pump is pulled for service?A - Yes, we do. Just tell us the size of the seal.
Q - Do you make a 6 x 4 Lemco Seal?
A - No, we don't, the flange would be too narrow. Same for an 8 x 6 seal.
Q - Will the seal still control drawdown if it's mounted 20-30 feet above the pump?
A - To best control drawdown, it should be mounted as close to the pump as possible.
Q - Will the Lemco Seal work to stop the flow in an artesian well?
A - It depends on how much flow there is. Some have used two or more successfully.
