5 The GR Series ' improving reliability simple external design has only two moving parts and only one shaft seal to insure long life and ease of maintenance. High Speed Capability translates into lower costs and higher efficiency. Only one coupling guard No speed reducers Higher speed motors Sideplates and body are doweled to insure accurate internal alignment. Joints are ground to maintain clearances and eliminate the necessity of gaskets Convertible Stuffing Box allows for ample packing or mechanical seals to be used for greater flexibility Large, Unobstructed Suction and Discharge passages keep entrance losses and turbulence to a minimum High Capacity Double Row Roller Bearings are anti-friction to assure long life Babbitted Carbon Sleeve Bushings may be used when handling liquids with Operating Parameters Back Pullout Design facilitates poor lubricity or low Flows to 275 m3/h (1200 gpm) maintenance by allowing faster viscosities.
