Abstract: A gas compression device (10) is provided with a compressor (16) and a recovery section (20). The recovery section (20) is provided with a recovery passage (22), an auxiliary compressor (24) which is provided in the recovery passage (22), and a recovery tank (26) which is provided in the recovery passage (22). When gas leaks from the main compressor (16), the auxiliary compressor (24) is driven and the leaked gas is compressed. The leaked gas, the pressure of which has been increased by the auxiliary compressor (24), flows into the recovery tank (26) and is stored therein. The gas within the recovery tank (26) is fed to a suction passage (14).

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 diaphragm failure monitoring system for detecting leakage in a diaphragm of a diaphragm pump. The system includes a pump having an operating chamber containing a working fluid and a pumping chamber for pumping material into and out of the pump and a diaphragm separating the operating and pumping chambers. A first optic fiber is joined to the operating chamber for transmitting an optic signal across the working fluid. A second optic fiber is joined to the operating chamber for receiving the optic signal from the first optic fiber. An electric signal establishing device establishes a first electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through uncontaminated working fluid. The electric 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 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.

Abstract: An electric diaphragm pump having a pump head assembly in a first housing, a motor assembly in a second housing, a fluid sensor, and a leak alert system and/or pump shut-off system. The fluid sensor detects a presence of fluid which has leaked outside of a pump chamber and is located within a cavity of the diaphragm drive chamber. The leak alert system indicates that fluid has been detected by the fluid sensor and the shut-off control system stops operation of the pump based on fluid being detected by the fluid sensor.

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.
