3 Efficiency and low life cycle External HerringboneGear DesignDesigned to reliably handle viscous fluids across a broadrange of flows and pressures,the GR Series simple betweenbearing gear design is the mostrobust in the industry. Benefits of the GR include: Pulse-free operation Mechanically and hydraulically balanced Self-priming No gear box required Speeds to 1800 rpm Run dry capability whenpacked Ease of maintenance Low NPSHR Only one mechanical seal No external lubricationrequired Improved reliability Minimal shaft deflection Long mechanical seal life Reduced bearing loads Superior high pressure capability Suitable for fluids with poorlubricating characteristics Reduced wear ratesGR SeriesBetween Bearing,External GearPumpGASG earex(PS-60-3a) GR 2/24/05 12:31 PM Page 3 Pump DivisionGR SeriesBetween Bearing,External GearPump4GR Series pumps provide highefficiency, pulse-free pumping,even under the most challengingconditions.

4 They are designedto handle viscous fluids acrossa broad spectrum of flowsand pressures. The GR Series simple external design has onlytwo moving parts and only oneshaft seal to insure long lifeand ease of in standard sizesfrom 40 mm to 200 mm( in to 8 in) ports, the GRSeries pumps are construction is castiron and carbon steel. High Speed Capabilitytranslates into lower costsand higher efficiency. Only one coupling guard No speed reducers Higher speed motorsSideplatesand body aredoweled to insure accurateinternal alignment. Jointsare ground to maintainclearances and eliminatethe necessity of gasketsConvertible Stuffing Boxallows for ample packing or mechanical seals to beused for greater flexibilityLarge, Unobstructed Suction and Dischargepassages keep entrancelosses and turbulence to a minimumHigh Capacity Double Row Roller Bearingsare anti-friction to assurelong lifeBabbitted Carbon SleeveBushingsmay be usedwhen handling liquids withpoor lubricity or lowviscosities.
