INTRODUCTION We welcome you as a user of AC Fire Pump. Your pump is a product of careful engineering and skilled workmanship. We believe you have the best pump possible for the service intended. With care and preventative maintenance, our AC Fire Pump will deliver efficient, trouble-free service. rating plate to identify the pump in his operation. (e.g. CWP-11 stands for Chilled Water Pump No.
SAFETY INSTRUCTION The warning and caution decals located on the pump are there for the safety of anyone involved with the installation, operation, and maintenance of the pump. PLEASE READ THE DECALS CAREFULLY. SAFETY INSTRUCTION This safety alert symbol will be used in this manual and on the pump safety instruction decals to draw attention to safety related instructions.
INSTALLATION RECEIVING THE PUMP Check the pump for damage immediately upon arrival. (An absolute must!) Prompt reporting of any damage to the carrier’s agent, with notations made on the freight bill, will expedite satisfactory adjustment by the carrier. NYLON SLING, CHAIN OR WIRE ROPE Pumps and drivers are normally shipped from the factory mounted on a baseplate. Couplings may either be completely assembled or have the coupling hubs mounted on the shafts and the connecting members removed.
Using ANSI/OSHA Standard “S” hooks, place the “S” hooks in the holes provided in the four corners of the base. Be sure the points of the hooks do not touch the bottom of the pump base. Attach nylon slings, chains, or wire rope to the “S” hooks. Size the equipment for the load, and so the lift angle will be less than 45° from the vertical. or wire rope using latch hook or standard shackle and end loop.
30º MAX Cortec Corp. VCI-329 (for both grease and oil lubricated bearings). Seal all vents and apply a water proof tape around the oil seals in the bearing frame. Remember for pumps with oil lubricated bearings to drain the oil from the frame and refill to the proper level before running the pump. NYLON SLING, CHAIN, OR WIRE ROPE LOCATION The pump should be installed as near to the suction supply as possible, with the shortest and most direct suction pipe practical.
The foundation should be poured without interruption to within 1/2 to 1 ½ inches of the finished height. The top surface of the foundation should be well scored and grooved before the concrete sets; this provides a bonding surface for the grout. FIGURE 9A – SETTING BASE PLATE AND GROUTING YEAR 2000 STYLE BASE FOR BOTH MOTOR AND ENGINE DRIVEN UNITS BASEPLATE Foundation bolts should be set in concrete as shown in Figure 8.
dried thoroughly according to instructions. Final alignment should be made by shimming driver only. Alignment should be made at operating temperatures. piping to pump. (24 hours is sufficient time with approved grouting procedure.) GROUTING PROCEDURE Grout compensates for uneven foundation, distributes weight of unit, and prevents shifting. Use an approved, non-shrinking grout, after setting and leveling unit (See Figure 9).
straddling the support arm, and install but do not tighten the two remaining capscrews. f. Position the outer guard so it is centered around the shaft, and so there is less than a 1/4" of the motor shaft exposed. On guards that utilize a slotted support bracket, the inner guard will have to be positioned so there is only a 1/4" of the pump shaft exposed. ii.
i. For single element couplings, a satisfactory parallel misalignment is .004"T.I.R., while a satisfactory angular misalignment is .004"T.I.R. per inch of radius R (See Figure 10B).
should be roughly equal to the shaft diameter. misalignment, strike the side of the motor foot with a mallet. 11. Tighten the motor bolts and check again. If a correction is made, re-check alignment in all directions. Repeat this process until the desired result is obtained. 5. Tighten setscrews. 6. Bring the pump and motor halves of the coupler into approximate height alignment, by placing equal amounts of shims under all the motor feet. 12.
gaskets stay in position during fastener tightening. FIGURE 10G – COVER INSTALLATION, VERTICAL POSITION 17. Ensure the lube plugs are installed in the cover. WARNING: Coupling Failure FIGURE 10F – COVER INSTALLATION Do not operate coupling without proper lubrication 16. If the shafts are not horizontal, or coupling is to be used vertically, assemble cover halves with the lug and match mark UP or on the high side.
OPTIONAL Alignment Procedure If desired, the pump and motor feet can be doweled to the base after final alignment is complete. This should not be done until the unit has been run for a sufficient length of time and alignment is within the tolerance. See Doweling Section. Final Alignment Final alignment cannot be accomplished until the pump has been operated initially for a sufficient length of time to attain operating temperature.
Make sure that all piping joints are air-tight. SUCTION AND DISCHARGE PIPING The introduction of a pump into a piping system which is not well designed or adjusted may cause strain on the pump, leading to misalignment or even impeller rubbing. Since slight strain may go unnoticed, final alignment should be done with the system full. Where flanged joints are used, assure that inside diameters match properly. Remove burrs and sharp edges when making up joints.
WATER VELOCITY INCREASES HERE, CAUSING A GREATER FLOW TO ONE SIDE OF THE IMPELLER PUMP CASING PUMP SUCTION SUCTION FLANGE ELBOW CASING RINGS IMPELLER FIGURE 12 – UNBALANCED LOADING OF A DOUBLE SUCTION IMPELLER DUE TO UNEVEN FLOW AROUND AN ELBOW ADJACENT TO THE PUMP 2. When foot valves are used, or where there are other possibilities of “water hammer,” close the discharge valve slowly before shutting down the pump.
SUCTION PIPE INSTALLED WITH A GRADUAL RISE TO PUMP Discharge Piping If the discharge piping is short, the pipe diameter can be the same as the discharge opening. If the piping is long, the pipe diameter should be one or two sizes larger than the discharge opening. On long horizontal runs, it is desirable to maintain an even a grade as possible. Avoid high spots, such as loops, which will collect air and throttle the system or lead to erratic pumping.
Only a sufficient volume of sealing liquid to create a definite direction of flow from the stuffing box inward to the pump casing is required, but the pressure is important. Apply seal water at a rate of approximately .25 GPM at a pressure approximately 15 to 20 psig above the suction pressure. (Approximately one (1) drop per second.) difficult. Consideration should be given to using a mechanical seal. (See Mechanical Seals.) Packing Standard pumps are normally packed before shipment.
Mechanical Seals Mechanical seals are preferred over packing on some applications because of better sealing qualities and longer serviceability. When a seal is properly installed, it will last longer than packing on similar applications. A mechanical shaft seal is supplied in place of a packed stuffing box when specifically requested. The change from packing to an alternate arrangement may be made in the field by competent service personnel.
OPERATION each time the motor leads have been disconnected. PRE-START CHECKS WARNING: Unexpected Startup Hazard Disconnect and lockout power before servicing. Failure to follow these instructions could result in serious personal injury or death, or property damage. PRIMING If the pump is installed with a positive head on the suction, it can be primed by opening the suction valve, and loosening the vent plug on top of the casing (Do not remove), allowing air to be purged from the casing.
4. Temperature: Check and record bearing temperatures using a thermometer. Temperature should not exceed 180°F. the anchors and supports are not adequate or set properly and should be corrected. STARTING 1. Close drain valves and valve in discharge line. 5. Vibration and Sound: The acceptable vibration level of a centrifugal pump depends on the rigidity of the pump and the supporting structure. Recommended values for vibration can vary between .20 ips (inches per second) velocity to .
CAUTION: If heat is used to keep the pump from freezing, do not let the temperature rise above 150°F. FIELD TESTS A typical performance curve for a specific pump can be obtained from AC Fire Pump. This can be used in conjunction with a field test, if one is required. All AC Fire Pump tests and curves are based on the Hydraulic Institute Standards. Any field test must be conducted according to these Standards.
MAINTENANCE recommended lubricants. Depending on the length of time the pump has remained in the flooded area, it is unlikely that bearing replacement is necessary; however, in the event that rust or worn surfaces appear, it may be necessary to replace the bearings. GENERAL MAINTENANCE AND PERIODIC INSPECTION Operating conditions vary so widely that to recommended one schedule of preventative maintenance for all centrifugal pumps is not possible.

Any greater amount will, as a rule, be discharged by the seal or vent and be wasted. plugs for the first 24 hours of operation after regreasing. Bearing Temperature Normally the maximum desirable operating temperature for ball bearings is 180°F. Special designs may have higher limits.
into operation check the condition of packing. If pump is installed within sixty (60) days after shipment the packing will be in good condition with a sufficient supply of lubrication. If pump is stored for a longer period it may be necessary to repack the stuffing box. In all cases, however, we recommend an inspection of the packing before pump is started.

c. A mechanical seal which has been used should not be put back into service until the sealing faces have been replaced or relapped. (Relapping is generally economical only in seals two inches in size and above.) or sleeve for possible scoring or eccentricity, make replacements where necessary. New packing (non-asbestos) should be placed carefully into the stuffing box. If molded rings are used, the rings should be opened sideways and the joints pushed into the stuffing box first.
MAINTENANCE TIME TABLE EVERY MONTH EVERY 3 MONTHS EVERY 6 MONTHS Check bearing temperature with a thermometer, not by hand. If bearings are running hot (over 180°F), it may be the result of too much lubricant. If changing the lubricant does not correct the condition, disassembly and inspect the bearings. Lip seals bearing on the shaft may also cause the housing to run hot. Lubricate lip seals to correct. Check the oil on oil lubricated units. Check grease lubricated bearings for saponification.
TROUBLE SHOOTING Between regular maintenance inspections, be alert for signs of motor or pump trouble. Common symptoms are listed below. Correct any trouble immediately and AVOID COSTLY REPAIR AND SHUTDOWN. CAUSES CURES No Liquid Delivered 1. Lack of prime. Fill pump and suction pipe completely with liquid. 2. Loss of prime. Check for leaks in suction pipe joints and fittings; vent casing to remove accumulated air. Check mechanical seal or packing. 3.
TROUBLE SHOOTING (cont.) Causes Cures 16. Impeller partially plugged. See item 9. 17. Cavitation; insufficient NPSHA (Net Positive Suction Head Available). a. Increase positive suction head on pump by lowering pump or increasing suction pipe and fittings size. b. Sub-cool suction piping at inlet to lower entering liquid temperature. c. Pressurize suction vessel. 18. Defective impeller and/or wear rings. Inspect impeller and wear rings.
TROUBLE SHOOTING (cont.) Causes Cures Pump Operates For Short Time, Then Stops 30. Insufficient NPSHA. See item 17. 31. System head too high. See items 4 and 10. Pump Takes Too Much Power 32.
