    Abstract: Method and apparatus for detecting leaks or defects, including component failure and adverse performance, in a fluid pumping system having a pumping chamber, piston (21), motor (35), inlet, outlet, inlet valve, switchable valve and detector (29). The inlet valve (37) is in fluid communication with the inlet (17) while the switchable valve (41) is in fluid communication with the outlet (19). A pressure measuring device (45) is in fluid communication with the pumping chamber (15) between the inlet valve and switchable valve so as to determine a minimal pressure together with first and second threshold pressures measured at first and second times that correspond to first and second threshold pressure signals. A control means (51) calculates the slope of a line representing the difference of such first and second threshold pressure signals over time so as to compare the slope to a threshold decay value, or to compare the minimal pressure to minimal acceptable values, thus defining pump defects.

    Abstract: A method and an apparatus for testing the piston (2) of an injection pump of a pressure medium, the piston comprising a longitudinal groove (2b) that begins from its frontal face (2a) and extends on its side, and a screw-shaped guide edge (2c) that abuts on the envelope surface of the piston. According to the invention, the piston (2) is inserted, with its frontal face (2a) first, into a testing cylinder (1), wherein the clearance between the piston (2) and the testing cylinder (2) is tight and wherein a specific testing pressure is exerted on the envelope surface of the piston, in a limited area, from the vicinity of the said guide edge (2c) to a selected measurement point. The piston (2) is moved in the testing cylinder (1), so that the said measurement point moves, following the guide edge (2c). Changes in the testing pressure are monitored to observe any failures in the piston (2) and the said guide edge (2c).

    Abstract: A sealing system for a pump having a plunger includes a housing having an internal chamber adapted to receive a portion of the plunger. Primary and secondary seals are located within the internal chamber and adapted to sealingly engage the plunger. The primary seal communicates with the fluid being pumped. A barrier fluid chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressure referencing device has an inlet port in communication with the pumped fluid and an outlet port providing fluid at a pressure magnitude equal to a peak pressure of the pumped fluid. A pressurizing device is in communication with the fluid at the peak pressure and the barrier fluid to maintain the barrier fluid pressure at a magnitude greater than the peak pressure of the pumped fluid such that the pumped fluid is restricted from leaking past the primary seal.

    Abstract: A diaphragm failure monitoring system for detecting leakage in a diaphragm of a diaphragm pump. The system includes a pump (10) having an operating chamber (16) containing a working fluid (30) and a pumping chamber (14) for pumping material into and out of the pump and a diaphragm (18) separating the operating and pumping chambers. A first optic fiber (52) is joined to the operating chamber for transmitting an optic signal across the working fluid. A second optic fiber (60) is joined to the operating chamber for receiving the optic signal from the first optic fiber. An electric signal establishing device (56) establishes a fist electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through uncontaminated working fluid. The electrical signal establishing device establishes a second electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through contaminated working fluid, whereby leakage of a contaminating material through the diaphragm into the operating chamber can be detected when the second electrical signal is established.

    Abstract: A sealing system for a pump includes a housing having an internal chamber adapted to receive a portion of a plunger. A primary seal is translatable within the chamber in sealing relation with the housing. The primary seal includes first and second elastomeric members adapted to sealingly engage the plunger. The first and second elastomeric members are spaced apart from one another a distance greater than or equal to a maximum stroke of the plunger. A secondary seal is spaced apart from the primary seal and adapted to sealingly engage the plunger. A chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressurizing device maintains a pressure of barrier fluid at a magnitude greater than a peak pressure of a fluid pumped by the plunger such that the pumped fluid is restricted from entering the barrier fluid chamber.

    Abstract: A plunger pump for supplying solution in accordance with an extrusion action of a plunger within a pump chamber. The plunger pump includes a cleaning chamber sealed by a seal member around and relative to the plunger, with a cleaning liquid inlet-side flow conduit and a cleaning liquid outlet-side flow conduit for communicating with the cleaning chamber, respectively. A mechanism isolates one of the inlet- and outlet-side flow conduits from the atmosphere and releases the other to an atmosphere under a condition where the cleaning liquid inlet- or outlet-side flow conduits are filled with the cleaning liquid. If the seal member in sliding contact with the plunger is degraded or aged, it is possible to observe a leakage of the liquid from the pump chamber along a sealing face between the seal member and the plunger.
