Pressure Powered Pumps

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.


Do I need electricity for a pressure powered pump?

No, float operated pumps require no electricity. Float free pressure powered pumps can use pneumatic valves and only require 115V electricity.

I have a critical application that cannot go down. How do I ensure that?

Many Liqui-Mover pressure powered pumps have been in continuous operation for decades and have few moving parts to fail.

Can I upgrade my level sensor on a non-Kadant pressure powered pump?

Yes, both the float and probe operated level control will retrofit major brands while bringing the features and benefits of the Kadant design.
