Abstract:
1. A modular header body for connecting to a pump motor, a fluid source, and a fluid circulation circuit, said modular header body comprising: a suction chamber in fluid communication with the fluid source, said suction chamber having a first opening at a first end and a second opening at a second end; a discharge for providing fluid to the fluid circulation circuit; a volute for receiving an impeller connected to the pump motor and for forcing fluid through said discharge; and a valve encapsulated within said suction chamber, the valve for selectively isolating said volute from said suction chamber, wherein at least one of said first opening and said second opening is configured to be connected to a second modular header body, wherein fluid is prevented from flowing from said suction chamber to said volute responsive to removing said motor from said volute when said valve is in a closed state.
