Abstract
A reciprocating piston pump may include a fluid handling portion comprising a fluid inlet, a fluid outlet, and a pump chamber; a drive assembly portion comprising a piston drive assembly, a reciprocating piston, a drive assembly housing, and a drive assembly chamber; and an electro-fluidic leak detection element comprising a fluid sensing portion. The reciprocating piston of the drive assembly portion extends into the pump chamber of the fluid handling portion. The piston drive assembly operates to reciprocate the reciprocating piston within the pump chamber. The electro-fluidic leak detection element is mounted within the drive assembly portion. The electro-fluidic leak detection element is configured to generate a fluid leakage signal when fluid from the pump chamber enters the drive assembly chamber and contacts the fluid sensing portion of the electro-fluidic leak detection element. A plurality of reciprocating piston pumps may be incorporated into fluid handling systems.
