Description: Oberdorfer N9000RBronze Pedestal Gear pump with relief valve. Often used as a oil pump on large ships to pre-lube the bearings.Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of liquid relatively unaffected by the backpressure in the discharge line. Shaft speed and flow are directly proportional.Maximum shaft speed is 1750 rpm.Recommended pressure limits are 100 psi for water and non-lubricants, 150 psi for oil and lubricants.A relief valve is a necessary in the system if the discharge line contains any throttling devices, such as a shut-off valve, a spray nozzle or other restrictive device. This will return the liquid to the suction side or to the tank. However, built-in relief valves are only good for intermittent service. If used continuously, the pump will over heat. A built-in relief valve is strictly a safety device against overpressure. It will not work successfully as a pressure or flow control device. For this purpose a separate relief valve in the pressure line must be used.Service life will be increase substantially if the liquid pumped is clean and has a lubricity value. These pumps have extremely close tolerances.Pump housings and gears are made of top quality bronzeShafts are from stainless steel 303Bearings are designed of high performance carbon-graphite material selected for wear resistance and long service life More InformationModel NumberN9000Rpart numberN9000RSeriesN9000 Pedestal Bronze Rotary Gear PumpsMax Flow (GPM.)23Max Flow GPH1380TDH Maximum (Ft)346TDH Maximum (PSI)150Inlet Connection TypeFNPTinlet size1"Inlet (In.)1Outlet Connection TypeFNPTOutlet (In.)1Wetted Materials304SS, BronzeSpeed (RPM.)1725Self PrimingYesSuction Lift (FT.)20Max Operating Temperature (F)350ViscosityGlycerine 880.00 cp 5000.00 ssuShaft304SSMechanical SealPACKINGMechanical Seal TypeSingleCouplingYOtherShaft Size: 5/8"Pump BearingCarbonDrainNoPort RotationYesCountry of ManufactureUnited States
