A vertical deep well pump is generally a motor and pump combination, which mounts to a ground level foundation and has extension tubes which reach into the water below. These types of pumps are generally used for scale pits and other large water collection sumps. Some vertical deep well pumps are submersible, which mean they submerge directly in the water at greater depths. They pump vertically through pipes to the ground surface. Some vertical deep well pumps are built in stages and use impellers to thrust the water upward. Contact Casey Equipment for a quote on used vertical deep well pumps for sale.
