General Safety Information > o Ffor Series9300 centrifugal pumps.3.Disconnect power before servicing. 4.Release all pressure within the system beforeservicing any component.5.Drain all liquids from the system before servicingany component. Flush with water.6.Secure the outlet lines before starting the pump. Anunsecured line may whip, causing personal injury and/or property damage.7.Check hose for weak or worn condition before eachuse. Make certain that all connections are tightly secured.8.Periodically inspect the pump and the systemcomponents. Perform routine maintenance as required (See...

Figure 3Gerotor-TypeHydraulic Motor Closed Center Load Sensing Systems (Flow and Pressure-Compensating) Figure 1Open CenterSpool Valve InNeutral Position The Closed Center Flow-Compensated System is avariation of the pressure-compensated system, designed primarily for more efficient operation and the generation of less heat. It works on the principle of maintaining a constant pressure drop from the pump to the work port of the selector valve. Any variation in demand at the motor will cause a change in flow. The system senses this change in flow due to the change in pressure drop across the...

Controlling the Pump Flow Centrifugal Pump Control The best way to control the flow is by incorporating twocontrol valves in a pipe tee immediately after the strainer in the discharge line. This permits controlling agitation flow independently of nozzle flow.In any centrifugal pump, it is the large volume of liquid whichputs load on the drive. Use only the flow needed to develop the pressure required at the boom and to maintain adequate agitation. Hydraulic motor-driven centrifugal pumps are easily adjusted to the exact flow required, as explained in the Operating Instructions of this...

OUT )port adapter with a built-in check valveassembly will guard against reverse operation allowing you to reverse oil flow to operate other equipment. Thisadapter must not be removed. On HM2C and HM4Cmodel pumps, the pressure ( IN )port adapter is a two-pieceassembly consisting of an open (unrestricted) adapter with three orifices packed loose with the pump. (See the Operations Section.) Agitation Nozzle Bodies > The centrifugal pump control contains a manual agitationcontrol valve that can be adjusted to provide the right amount of flow to the jet agitators in the tank to ensure proper...

Adjusting Centrifugal Pump Output 1.Make sure the orifice from the pressure port adapter ofthe hydraulic motor has been removed (HM2C and HM4C models only).2.Close and lock down the bypass adjusting screw in thehydraulic motor.3.Set the tractor hydraulic flow control valve for minimumhydraulic oil flow to the remote outlet (Tortoise position).4.Start the tractor and allow the hydraulic oil to circulatefor approximately 10 to 15 minutes or until adequately warmed.5.Prime the centrifugal pump with all valves open (Seethe Installation Instructions and System Configuration Diagram).6.Close the...

]7.Install the o-ring on the mounting flange. Replace theo-ring if worn or damaged.8.Place the pump casing on the mounting flange, insertand tighten the bolts. 3.Using a screwdriver and hammer, tap out the stationaryportion of the Mechanical Seal from the motor side of the Mounting Flange. (If the motor is not removed, the seal can be pried out with a small screwdriver.) Onpolypropylene models, insert the Woodruff Key into the Shaft key slot. Place the Impeller on the Shaft and align it with the Key; then press against the Mechanical Seal Assembly. Place the Metal Seal Washer on the Shaft....

apart the boss area between the Gerotor Housing andthe Motor Body. (It may be necessary to alternate sides when prying apart Motor sections.) Hydraulic Motor Shaft Disassembly and Repair 1.Remove Large Retaining Ring from Shaft with ascrewdriver. Remove Thrust Bearing Assembly from Shaft (includes the Thrust Bearing and two Thrust Bearing Races) and the Seal Spacer.2.Remove the Small Retaining Ring next to the Shaft BallBearing. Figure 11 3.To remove the Bearing from the shaft, place the shaft(threaded end up) in the arbor press fixture. Place the two support bars provided in the repair kit...

4.Install the outer portion of the Gerotor, making sure theGerotor is centered within the o-ring groove on the body.5.Install the Gerotor Housing, making sure the pins in theGerotor Housing line up with their respective holes in the body.6.Lightly lubricate the area between the Inner and OuterGerotor and the Outer Gerotor and Gerotor Housing with hydraulic oil or mineral oil. Special attention should be exercised when workingwith retaining rings. Always wear safety goggles when working with spring or tension-loaded fasteners or devices. 7.Install o-ring on the motor end plate. 8.Place end...
