Vertical Turbine Pumps

Close up of a PackRyt BLR - Bearing with integrated Lantern Ring and Premium Mechanical Packing

Vertical Turbine Pumps are commonly found in harsh environments- slurries, sea water, boiler feed, cooling tower, recirculation, dewatering, petro-chemical transfer, high pressure condensate, to name but a few.

By design, the very long shafts create substantial radial movement, so much so that pump manufacturers often design in bushings all the way down the column. These bushings are normally made of bronze, rubber, or carbon and all exhibit accelerated wear due to their material weaknesses. As they wear, the shaft moves increasingly freer and frequently wear the bushing housings themselves. This radial movement all along the shaft transmits to the stuffing box and causes both packing and mechanical seals to fail prematurely.

The SealRyt® Corporation’s patented technology presents the solution for successful sealing through use of a bearing (BLR, BRG, or ORM) in the bottom of the stuffing box and either SealRyt®‘s application-specific, Premium textiles or customer-supplied mechanical seal. Use of the PackRyt® system ensures the portion of the shaft in the stuffing box remains concentric with the bore thus enabling sealing method of choice to perform well.

Also, the SealRyt® Corporation has manufactured many bearings for replacement of OEM bushings all the way down the column. Arranged in OEM holders or “clamshells”, the SealRyt® bearings steady the entire shaft and far out-live the OEM standard. SealRyt® also offers factory installation of column bearings in customer supplied clamshells (press fit, shrink fit, etc. ).
