The heavy-duty, balanced, two-vane, semi-open ductile iron impeller provides maximum life. Pump out vanes on the back shroud reduce doreign material buildup behind the impeller, minimizing pressure on the seal and maximizing bearing life.

Gorman-Rupp's double-floating, self-aligining, oil-lubricated mechanical seal is specifically designed for abrasive and/or trash handling applications. The silicon carbide faces an extra large seal oil chamber provide superior dry-run capability. This patented cartridge design allows for accurate and easy installation.

A replaceable wearplate, matched to the cover plate, has Gorman-Rupp's patent pending, self-cleaning design to ensure debris is cleared away and does not collect on the impeller vanes. This innovative design reduces the overall life cycle costs by minimizing blockage.

All Ultra V Series pumps come standard with anti-rotation ribs within the seal chamber area, reducing internal wear, maximizing seal and plate life.

The shimless back cover plate adjustment allows for accurate maintenance of the clearance between the impeller and wearplate, without realigning belts, couplings or other drive components. Once adjustments have been made, the unique lock collar and adjusting screw maintains the clearance setting even if the cover plate is removed.
Peak pump efficiency is maintained, while doubling the life of the impeller and wearplate. The life of the wearplate is maximised with the combination of the shimless back cover adjustment and additional rotating assembly spacers.
