Submersible Pump Overview
Electric submersible pumps have been widely applied at remediation and landfill sites due to their familiarity, high flow rates, ready availability, and low initial cost. However, submersible pneumatic pumps specifically developed for remediation and landfill pumping have become the preferred alternative at many sites due to their unique capability to handle severe pumping applications. The key to choosing between these technologies is defining the site conditions and project objectives.
Most commercial submersible electric centrifugal well pumps were originally developed for extracting clean water from residential and commercial supply wells. Some modified versions are available to address the special needs of remediation pumping, but their basic technology remains the same as standard water supply pumps. Typical electric submersible pumps are best suited for providing high flow rates of clear water within a limited range of flow rate/discharge head combinations and on/off cycling rates. Historically, water supply pumps have not been designed to handle solids or to pump volatile, corrosive, viscous or high temperature liquids, which are common conditions in many remediation and landfill applications.
In recent years, advances in air-powered pump technologies have lead to their growing use at landfill and remediation sites that can benefit from their simplicity, durability, application flexibility, and lower maintenance costs. A comparison of major system characteristics and site variables is provided in the links below to help the specifier select the best pump for a landfill or remediation project.
