General Duty Pumps

“General Duty” pumps come in many colors and many different designs.  Most are designed with a power frame, containing radial and axial shaft bearings in an oil bath, an extended shaft surrounded by a stuffing box, and an overhung impeller inside a volute.

Most manufacturers of these pumps specify a B-10 life of the bearings at 100,000 hours, or  11.4 years.  When General Duty pumps fail to achieve 11.4 years before rebuilding,  SealRyt® looks at operating issues (throttling?), chemistry (improper metallurgy?), and the sealing area in general. A bad radial bearing normally means acute deflection of the shaft over time, water in the bearing housing normally means excessive stuffing box leakage making its way into the housing past the lip seal , and eroded parts means chemistry is present but not accounted for.

While this class of pumps tends to present the lowest number of sealing issues due to benign applications for them, any of them can be misused and misapplied. Chemistry vs. metallurgy can be sorted out easily, but misuse or faulty operation causes faulty sealing as well. SealRyt® has the answer.

With the installation of its patented PackRyt® system, the pump will no longer present elliptical movement of the shaft in the sealing area and will be sealed so well that water in the oil will no longer be an issue. This system contains a bearing/lantern ring (BLR) and specific, patented SealRyt® packing. The bearing portion stabilizes the shaft, allows the sealing rings to conform and seal, and establishes a new hydraulic balance at the throat of the pump which keeps the media out and automatically minimizes flush fluid in to the process. It is simple and very cost effective!!
