Pressure powered pumps move condensate using steam or air pressure. This allows processes to operate at low pressures, minimize moving parts, and eliminate the energy loss associated with cooling condensate for electric pumps.
Liqui-Mover float operated pressure powered pumps use a mechanical float and valve. They are recommended where limited capacity is needed and it is impractical to run electricity. Liqui-Mover float free pressure powered pumps have greater capacity, increased control of condensate levels, and eliminate moving parts in the level sensor. They are recommended in higher capacity and critical applications. Unlike electric pumps, pressure powered pumps are robust to high temperatures, pressures, and wet environments. Electric centrifugal condensate pumps use an impeller that uses suction to pump the condensate. Suction lowers condensate pressure causing boiling, cavitation, and impeller damage. Electric pumps often require condensate to be cooled to prevent pump damage and the heat energy is lost to the environment.
