D/G-10 InstallationLocationLocate the pump as close to the supply source as possible.Install it in a lighted clean space where it will be easy to inspectand maintain. Allow room for checking the oil level, changingthe oil, and removing the pump head (manifold, valve plate andrelated items).MountingThe pump shaft can rotate in either direction.To prevent vibration, mount the pump and motor securely on alevel rigid base.On a belt-drive system, align the sheaves accurately; pooralignment wastes horsepower and shortens the belt and bearinglife. Make sure the belts are properly tightened, as specified bythe belt manufacturer.On a direct-drive system, align the shafts accurately. Unlessotherwise specified by the coupling manufacturer, maximumparallel misalignment should not exceed 0.015 in. (0.4 mm)and angular misalignment should be held to 1° maximum.Careful alignment extends life of the coupling, pump, shafts,and support bearings. Consult coupling manufacturer for exactalignment tolerances.Important PrecautionsAdequate Fluid Supply. To avoid cavitation andpremature pump failure, be sure that the pump will havean adequate fluid supply and that the inlet line will not beobstructed. See “Inlet Piping”.Positive Displacement. This is a positive-displacementpump. To avoid severe system damage if the dischargeline ever becomes blocked, install a relief valvedownstream from the pump. See “Discharge Piping”.Safety Guards. Install adequate safety guards over allpulleys, belts, and couplings. Follow all codes andregulations regarding installation and operation of thepumping system.Shut-Off Valves. Never install shut-off valves betweenthe pump and discharge pressure regulator, or in theregulator bypass line.Freezing Conditions. Protect the pump from freezing.See also the Maintenance Section.Consult the Factory for the following situations:• Extreme temperature applications – above 160° F (71°C) or below 40° F (4.4° C)• Pressure feeding of pumps• Viscous or abrasive fluid applications• Chemical compatibility problems• Hot ambient temperatures – above 110° F (43° C)• Conditions where pump oil may exceed 200° F (93°C) because of a combination of hot ambienttemperatures, hot fluid temperature, and fullhorsepower load — an oil cooler may be required5 D10-991-2400 5/1/04
