  • Patent number: 11499546
    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.

  • Patent number: 11273446
    Abstract: A threaded fluidic fitting may include a fluid passage, at least one fluid port, a threaded fitting portion, an engageable body portion, and an electro-fluidic leak detection element. The fluid passage extends from the fluid port of the threaded fluidic fitting. The threaded fitting portion comprises a helical thread, extends from a leak detection face of the engageable body portion, and is configured to rotate with the engageable body portion to enhance a fluidically sealed engagement of one of the fluid ports with a complementary fluidic component. The electro-fluidic leak detection element is positioned on the leak detection face of the engageable body portion or on a drip edge portion of a face extending from the leak detection face. A fluid handling system may include a plurality of threaded fluidic fittings and a leak detecting computing hub in communication with the plurality of threaded fluidic fittings.

  • Patent number: 11105439
    Abstract: A pinch valve configuration may include a pinch valve comprising a valve body, a valve plunger, and a fluidic tubing pinch passage defined between a tubing seat of the valve body and an operative end of the valve plunger. The pinch valve configuration may further include a Hall effect sensor assembly comprising a stationary element anchored to the valve body and a motive element anchored to the valve plunger. The pinch valve configuration additionally includes a failure prediction module in communication with the Hall effect sensor assembly. The failure prediction module is programmed to process an output signal of the Hall effect sensor assembly as a displacement reading, to compare the displacement reading with a failure prediction threshold, and to generate a failure prediction signal from the comparison of the displacement reading with the failure prediction threshold.

  • Publication number: 20180073502
    Abstract: A reciprocating piston pump may include a pump chamber, a piston seal, a monolithic partially fluorinated polymer piston with a fluid engaging end, a seating end, and a longitudinal outer piston surface extending between the fluid engaging end and the seating end. The reciprocating piston pump may further include a drive assembly coupled to the seating end of the monolithic partially fluorinated polymer piston. The drive assembly operates to reciprocate the monolithic partially fluorinated polymer piston within the pump chamber between full aspirate and full dispense positions. The piston seal forms an interface between the longitudinal outer piston surface of the piston and the pump chamber. The monolithic partially fluorinated polymer piston and the drive assembly are configured such that the piston seal interfaces with the longitudinal outer piston surface over a full stroke length of the drive assembly between the full aspirate and full dispense positions.
