Page 5: Storage Before Installation
Section B Installation Procedures Storing Before Installation Your FMC pump will come to you prepared for any necessary storage periods before installation. Selecting Pump Location Always locate the pump as close to the source of supply as possible. The pump should also be located in a light, clean, dry space where adequate inspection and maintenance operations can be performed. - Page 6 Installing the Pump Suction Line Steps Procedures Determine the shortest most direct route possible for the suction hose. Make a preliminary design of suction piping. Remember the line should be as large, direct, and short as possible. NOTE: The line must be laid out so there are no high spots to cause air pockets.
- Page 7 Installing the Pump Suction Line - Con’t. Steps Procedures Install a foot valve when there is suction lift. The foot valve should be installed in the suction line near the fluid source. The foot valve will keep the lines to the pump filled and avoid the necessity of priming at each start.

Section C Operating Procedures Check Points Before Starting - Always make the following checks before starting the pump. Steps Procedures Make sure the magnetic drain plug in the bottom of the pump case is tight. Check the oil by means of the sight gauge; if necessary add a good grade of SAE 30 wt. -
Page 10: Starting The Pump
Starting the Pump Steps Procedures The following procedures should be followed when starting the pump for operation. Start the pump and listen for unsteady flow or erratic noises. Steps Procedures If unsteady flow persists repeat steps 1-5 until Open the gate valve in the suction line. (1) pump is properly primed. -
Page 11: Shutdown During Freezing Temperatures
Shutdown Procedures During Freezing Temperatures The following procedures should be followed when stopping or storing the pump during freezing weather. Steps Procedures Let the pump, pump air for a few seconds with the discharge outlet and suction line open. This will flush the valves and discharge lines. -
Page 13: Maintenance Procedures
Section D Maintenance Procedures Lubrication This triplex plunger (or outside packed) pump requires SAE 30 wt. lubricant in the crankcase. After the first 500 hours of operation drain the oil from the crankcase and remove any metal adhering to the magnetic drain plug. Thereafter, at the end of each of 5000 hours operation the oil must be drained and the drain plug(l) should be cleaned of any metal adhering to it. - Page 14 Periodic Maintenance Chart Before performing any maintenance on your pump read the Owner’s manual thoroughly. Description of Service Remarks Components Break-in Period Crankcase Drain oil from crankcase by removing plug. After the first 500 hours of operation. Clean any metal adhering to pump before replacing.

Page 17: Service
Section E Service Servicing the Fluid End Servicing the Valves - Malfunctioning valves are identified by a uniform hammering or vibration and by reduced pump capacity (volumetric efficiency). Steps Procedures WARNING Always disconnect pump from power source before performing any service to the pump. Failure to do this could cause electrical shock or injury from moving pump parts. - Page 18 Steps Procedures Lower the seat into the port taper and then lift slightly and let drop. If the seat drops straight, it will seize on the taper. When correctly seated, it cannot be pulled up by hand. It is necessary to rap it a few times to assure a perfect seal;...
- Page 19 Servicing the Plunger Packings Plunger packings must be replaced whenever the leakage around the packings affects the pump’s efficiency. A small amount of leakage past the packings is normal and is actually desirable to help cool and lubricate the packings. Your pump was designed for ease of maintenance.
- Page 20 Servicing the Plunger Packings - Cont’d. Steps Procedures Replace the adjusting nut (however, at this time, do not tighten down the nylon tipped set screws.) NOTE: In each new packing set there are three units of packing, composed of a female adapter, pressure ring, and a male adapter. The female adapter is the thin hard phenolic ring.
- Page 21 Servicing the Plunger Packings - Cont’d. Steps Procedures If the throat ring sticks up past the end of the stuffing box, the adjusting nut should be backed off and the throat ring pushed down so it is flush or below the end of the stuffing box.
- Page 22 Servicing the Plunger Packings - Cont’d. StepsProcedures Wipe the stuffing box counterbores in the valve chamber clean of debris before installing the stuffing box. Install the stuffing box with the plunger rod as far rearward as possible. This gives the maximum amount of room possible and simplifies assembly.
- Page 23 Servicing, the Plunger Packings - Cont’d. Steps Procedures Install the plunger clamp being careful to keep the gap between the upper and lower parts uniform while tightening torque as shown on page E-19. Torque the stuffing box hex nuts in the following manner: 1) Torque both nuts to approx.
- Page 24 Servicing the Drive End Servicing the crankshaft and connecting rods These components seldom need servicing or replacing unless the pump has been run without oil or with severely contami- nated oil. Problems with the shaft and rods will be indicated by a knocking noise or excessive pump case temperature. Steps Procedures WARNING...
- Page 25 Servicing the Drive End - Cont’d Steps Procedures Remove the bolts from the bearing housings. Remove bearing housings. It may be necessary to tap on housing with a rubber mallet to free housing from pump base. CAUTION Crankshaft should be carefully handled during bearing housing removal to keep from damaging or scarring the crankshaft or pump case.
- Page 26 Servicing the Drive End - Cont’d. StepsProcedures NOTE: All damaged bearings that have been removed from the shaft must be replaced with new bearings. If one bearing is faulty, it is a good practice to replace both bearings even though no damage is visible on the other bearing.
- Page 27 Servicing the Drive End - Cont’d. StepsProcedures Before installing the crosshead assemblies, remove the oil seal holders Reassemble the crosshead and connecting rod assemblies. Be sure to align the oil slot in the crosshead with the oil pocket and the connecting rod. Be sure to replace the set screw that retains the wrist pin.
- Page 28 Servicing the Drive End - Cont’d. Steps Procedures Replace the crankshaft by carefully threading the shaft through the openings in the end of the case. Take care not to damage the bearings. Replace shims and gasket and bearing housing. NOTE: The gasket goes against the pump case. The shims go between the gasket and bearing cover.
- Page 29 Servicing the Plunger Rod Oil Seals These seals retain oil in the pump case and prevent dirt and fluids from entering the case by way of the plunger rods. Oil leakage around the plunger, dirt on the case, or milky colored oil are signs of worn or damaged crosshead seals.
- Page 30 Servicing the Bearings A knocking sound around the bearing or excessive heat coming from the pump case adjacent to the bearing are indications of faulty bearings. To replace or inspect bearings, the crankshaft must be removed to allow access to the bearings. (Refer to step 13 Servicing the Drive End).
