Do not pump hazardous materials (flammable, caustic, etc.) unless the pump is specifically designed and designated to handle them. 3 A - GENERAL INFORMATION B - INSTALLATION TO THE PURCHASER: Congratulations! You are the owner of one of the finest pumps on the market today. These pumps are products engineered and manufactured of high quality components. With years of pump building experience along with a continuing quality assurance program combine to produce a pump which will stand up to the toughest applications. 1. FOUNDATION The pump foundation should be sufficiently substantial to form a level, rigid support for the combined weight of the pump and driver and maintain alignment of the installed unit. Foundation bolts, of the proper size, should be imbedded in the concrete. A pipe sleeve, about 2½” diameters larger than the bolt, should be used to allow for final positioning of the bolts. See Figure 1. Check local codes and requirements before installation. Servicing should be performed by knowledgeable pump service contractors or authorized service stations. 2. MOUNTING: Pumps and drivers that are received from the factory with both machines mounted on a common base plate, were accurately aligned before shipment. All baseplates are flexible to some extent and, therefore, must not be relied upon to maintain the factory alignment. Preliminary alignment is necessary after the complete unit has been leveled on the foundation, and again, after the unit is piped, and rechecked periodically as outlined in the following paragraphs. RECEIVING: Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file a claim immediately with the company that delivered the pump. If the manual is removed from the crating, do not lose or misplace. STORAGE: Short Term - Pumps are manufactured for efficient performance following long inoperative periods in storage. For best results, pumps can be retained in storage, as factory assembled, in a dry atmosphere with constant temperatures for up to six (6) months. Position unit on foundation and level the base plate, using rectangular metal blocks and shims, or wedges having a small taper as shown in Figure 2. A gap of 3/4” to 1½” should be allowed between the base plate and foundation for grouting. Adjust the metal supports or wedges until the shafts of the pump and driver are level. Check the coupling faces, as well as the suction and discharge flanges of the pump for horizontal or vertical position by means of a level. Correct the positions, if necessary, by adjusting the supports or wedges under the base plate, as required. Long Term - Any length of time exceeding six (6) months, but not more than twenty four (24) months. The units should be stored in a temperature controlled area, a roofed over walled enclosure that provides protection from the elements (rain, snow, wind blown dust, etc..), and whose temperature can be maintained between +40 deg. F and +120 deg. F. Pump should be stored in its original shipping container and before initial start up, rotate impeller by hand to assure seal and impeller rotate freely. SERVICE CENTERS: For the location of the nearest Deming Service Center, check your Deming representative or Crane Pumps & Systems Service Department in Piqua, Ohio, telephone (937) 778-8947 or Crane Pumps & Systems Canada, Inc., Bramton, Ontario, (905) 457-6223. Figure 2. Adjusting Wedges for Mounting Figure 1. Foundation Bolt Location and Anchorage 4 NOTE: A flexible coupling should not be used to compensate for misalignment of the pump and driver shafts. The purpose of the flexible coupling is to compensate for temperature changes and to permit end movement of the shafts without interference with each other, while transmitting power from the driver to the pump. ANGULAR MISALIGNMENT CAUTION! - Remove and lock out power to driver. 3. FIELD ALIGNMENT The faces of the coupling halves should be spaced far enough apart so that they cannot strike each other when the driver rotor is moved toward the pump. The necessary tools for checking the alignment of a flexible coupling are a straight edge and a taper gauge or a set of feeler gauges. NOTE: In most cases where extreme accuracy is necessary, a dial indicator may be used to align coupling. Angular alignment check is made by inserting a taper gauge or feelers between the coupling faces at 90-degree intervals around the coupling. The unit will be in angular alignment when the coupling faces are exactly the same distance apart at all points. (See Figure 3). PARALLEL MISALIGNMENT Parallel alignment check is made by placing a straight edge across both coupling rims at the top, bottom and at both sides. The unit will be in parallel alignment when the straight edge rests evenly on the coupling rim at all positions. Allowance may be necessary for temperature changes and for coupling halves that are not of the same outside diameter. Care must be taken to have the straight edge parallel to the axis of the shafts. Correction for Angular and Parallel Misalignment is made by adjusting the shims under the driver. After each change, it is necessary to recheck the alignment of the coupling halves, as adjustment in one direction may disturb adjustments already made in another direction. The permissible amount of coupling misalignment will vary with the type of pump and driver, but should be limited to approximately .002 inches per inch of shaft diameter when final adjustment is made. When the units are lined up cold, it is necessary to make allowance for the vertical rise of the driver caused by heating when in operation. When the preliminary alignment has been completed the foundation, bolts should be tightened evenly, but not too firmly. PERFECT ALIGMENT WARNING - Coupling guards must be used to avoid serious injury to operating personnel. 4. GROUTING Grouting compensates for unevenness in the foundation and prevents vibration and shifting after mounting is complete. Build a form around the base plate to contain the grout, and sprinkle area with water to obtain a good bond. The base should be completely filled with a good quality, non-shrinking grout. The usual mixture for grouting is one part Portland cement and two parts sand with sufficient water to flow freely. It is also desirable to grout the leveling pieces, shims or wedges in place. Foundation bolts should be fully tightened when grout has hardened, usually about 48 hours after pouring. Figure 3 5 C - OPERATION 5. PIPING The pump suction and discharge connections are not intended to indicate the required suction and discharge pipe sizes. The pipe diameter must be selected according to the requirements of the pumping system and recommended friction losses for the liquid being pumped. 1. PRIMING CAUTION: Before starting the pump, the casing and suction line must be filled with liquid, and air-vented through the vent pipe plugs. The pump must not be run until it is completely filled with liquid, because of danger of injuring some of the parts of the pump which depend upon liquid for lubrication. The discharge gate vale should be closed during priming. Be sure the mechanical seal and power frame are supplied with the proper lubrication. See LUBRICATION. Usually, it is advisable to increase the size of both the suction and discharge pipes at the pump nozzles to have minimum acceptable friction loss, suction pipe should never be smaller in diameter than the pump suction nozzle. When suction pipe is of larger diameter than the pump suction nozzle, an eccentric reducer is required to eliminate possible air or vapor pockets at the pump suction inlet. PRIMING BY SUCTION PRESSURE When operating with suction pressure (flooded suction), remove the pipe plug at the top of the casing and when pump is filled with liquid, replace plug. Both suction and discharge pipes must be supported independently near the pump, so that when piping is connected to the pump, no strain will be transmitted to the pump. Piping should be arranged with as few bends as possible, and, preferably, with long radius elbow whenever possible. PRIMlNG WITH FOOT VALVE AND STRAINER A foot valve and strainer may be installed on the lower end of the suction pipe to keep pump filled with liquid. Incorporate filler pipe in discharge pipe between pump and check valve. Remove pipe plug at top of casing, then fill suction pipe and pump with liquid. When pump is full of liquid, replace plug and close filler pipe. SUCTION PIPING A horizontal suction line must have a gradual rise to the pump. Any high point in the suction pipe can become filled with air and prevent proper operation of the pump and may cause loss of prime. The pipe and fittings must be free of all air leaks. CAUTION: When a foot valve and strainer are installed on the suction pipe, a spring loaded type check valve MUST be installed next to the pump in the discharge piping to prevent pump rupture from water hammer shock. Any valves or fittings should located at a distance equal to 5 to 10 times the diameter of the suction pipe from the pump suction nozzle. If an elbow must be installed at the pump suction, it should be installed in a vertical position to reduce unequal flow into the pump, which may cause cavitation in the pump. Priming by means of primer pump or ejector, attached to the pump, will also remove air from suction pipe and pump casing. When pump is filled with liquid, start motor and slowly open discharge gate valve. NOTE: A gate valve in the suction piping should not be used as a throttling device, as this may cause the liquid to overheat during operation. 2. STARTING THE PUMP On initial start up, the gate valve in the discharge piping should be closed and slowly opened after pump is up to speed and pressure developed. DO NOT operate pump for any appreciable length of time against a closed discharge valve, as this may heat trapped liquid excessively and damage the pump or seal. 6. WIRING For electric motor drives, connect power supply to conform with national and local codes. Line voltage and wire capacity must match the ratings stamped on the motor nameplate. 7. ROTATION Before starting the pump, check the required direction of rotation of the pump. The proper direction is indicated by a direction arrow on the pump casing. Separate the coupling halves, then start motor to see that it rotates in the direction required by the pump. If it does not, reverse any two main leads of the 3-phase wiring to the motor. The coupling halves can be reconnected and the pump primed for starting. The following important items should be checked as pump is started and placed in operation. a. Pump and driver securely bolted b. Coupling properly aligned c. Piping complete d. Correct pump rotation e. Pump shaft turns freely f. Discharge valve closed g. Suction valve open (if used) h. Coupling Guard installed i. Pump fully primed j. Pump and driver properly lubricated Only after these items have been checked should the pump be started. 6 3. PUMP ADJUSTMENT Open discharge valve as soon as operating speed has been reached. As soon as the pump and driver have reached the normal operating temperature, the unit should be shut down for final coupling alignment. If correction is necessary, it may be accomplished by the addition or removal of shims from under the motor mounting feet. PACKING BOX - Packing must be continuously lubricated. Packed pumps are normally furnished less an external recirculation line. When operating with suction lift and clean liquid, recirculation from the pump discharge to the packing box (or suitable grease) may be used. When lubrication is supplied from an outside source, it should be cool, clear water, light lithium base grease or a compatible lubricating fluid. D. MAINTENANCE PACKING BOX CARE - Before installing new rings of packing, clean the packing box and inspect parts for wear. If the shaft sleeve is worn, replace it; new packing will not do an adequate job on a worn sleeve. Die molded packing rings are preferable. Insert two rings. Twist the rings sideways when installing; DO NOT pull the rings straight out over the shaft. Stagger the joints to minimize leakage. 1. LUBRICATION Model 3031/3131 units are available with either grease or oil lubricated bearings. The pump and its component parts that require lubrication have been lubricated at the factory. Subsequent lubrication depends on operating conditions. Periodic inspection of bearing lubrication is necessary and additional grease should be added as required. Tamp each ring in place and then slip the lantern ring into the packing box behind them. Add three more rings behind the lantern ring. Replace the gland and bolts, rotate the shaft, and tighten gland securely. Be sure the lantern ring is positioned to receive lubrication through the orifice in the housing. Tighten nuts securely to seat the packing, rotate the shaft several turns, and then loosen the nuts to “fingertightness” for starting. CAUTION: DO NOT over grease bearings The following lubricants are recommended: Grease lubricated ball bearings: Shell Dolium R, Chevron SRI #2 or equivalent -40° thru 250°F. IMPORTANT - Liquid being pumped should drip slowly but constantly through the packing gland. This will prevent overheating, high power consumption, and shaft sleeve damage. Oil lubricated pump are shipped WITHOUT oil in the frame. Install the Trico Opto-Matic® oiler on the frame with its moveable oiler body 1/4” higher than its lowest level. Fill the plastic bottle with oil (0°F - 150°F, #10 Wt. Nondetergent, 150°F - 250°F, #20 Wt. Non-detergent) and screw it into the lower reservoir. Several fillings of the bottle will be required before the frame stops taking oil. Never fill the frame through the lower oil reservoir. For normal 8 hour duty change the oil approximately every 6 months, more or less frequently depending on the operating conditions. If packing replacement becomes frequent: a. Check motor bearing for excessive wear causing shaft run-out. b. Check packing for proper grade. Also, check whether special packing issued: see pump data card. c. Check shaft sleeve for excessive wear or scoring. d. Check for crystallization of solution and for embedded abrasives in the packing. Method of packing lubrication may not be satisfactory. e. Check recirculating line, if used, as well as relevant fittings, for partial or full blockage. Driver: See Manufacturers recommendations for proper lubrication. WARNING! NEVER try to adjust or work on the pump while it is running. Always stop the unit completely before attempting any adjustment. INITIAL ADJUSTMENTS PUMP WITH MECHANICAL SEALS After the pump has been started, packing box glands should be tightened to prevent excessive loss of liquid. Mechanical seals are factory-adjusted at the time the pump is assembled and, normally, need no further adjustment in the field. The only prerequisite to operating a pump equipped with a mechanical seal is to make certain the seal chamber is filled with a compatible liquid before starting the pump. In cases where packed pumps are operating with a suction lift over 15 feet, the packing should be lubricated through the stuffing box tap from an external source. See “Packing Box” below. Packing should not be too tight, as this will result in burning the packing and scoring of the shaft sleeve. The best gland adjustment will allow liquid to drip slowly from the packing box gland. Normal drip rate is from 40 - 60 drips per minute. This will permit proper lubrication of the shaft and dissipate generated heat. The gland must NEVER be tightened to the point where leakage through the stuffing box is completely stopped. SINGLE SEAL - Pumps with single seals are normally furnished with an external recirculation line. A portion of the liquid being pumped is recirculeted from the casing through the seal chamber to serve as a lubricant and coolant. An alternate method is to supply a cool, compatible lubricating liquid from an outside source, to the seal chamber at a pressure 15 to 25 psi higher than suction pressure. 7 b. Remove hex nuts (210) and remove split gland (17) when pump is fitted with packing (13). If pump has mechanical shaft seal (89), remove hex nuts (210) and carefully slide seal gland (251) with seal seat away from packing box cover (11). DOUBLE SEAL - On double seal applications, the seal chamber must be filled with lubricant or clear, compatible lubricating liquid under pressure. The liquid may be from an outside source or may be from the pump discharge passing through a filter and/or heat exchanger when necessary. Pressure on the box must be 15 to 25 psi higher than suction pressure. The liquid must circulate through the outlet and a restriction must be placed in the outlet to assure pressure on the seal chamber. c. Remove the packing box cover from adapter (071). Packing (013) and lantern ring (029) may now be removed. d. If pump includes single mechanical shaft seal, scribe a mark at the seal retainer or spring retainer on the shaft sleeve or shaft to aid in reassembly. Remove seal gland gasket. E - REPAIR WARNING - If pumping any fluid that could cause bodily injury (hot water, caustic, etc.), always use eye protection and wear protective clothing over all exposed body areas. SINGLE SEAL PUMPS ONLY: e. Loosen set screws (K) in spring retainer (C) or seal collar. Remove seal from sleeve. DOUBLE SEAL PUMPS ONLY: f. Remove rotating portion of seal from the sleeve, and stationary sealt (A) and gasket (259) from the gland and packing box. REMOVE AND LOCK-OUT POWER TO THE DRIVER WHILE PERFORMING THESE TASKS Be sure that no one can accidentally restore power while the pump is being serviced. 1. IMPELER ADJUSTMENT - To adjust the impeller, loosen the capscrew (337) and rotate the clip (204) clockwise until it disengages the bearing housing lugs. Turn the bearing housing (033) clockwise until the impeller just rubs on the casing. Turn the bearing housing counter-clockwise two notches for 3031 units and 1 revolution for 3131 units. Replace the clip and tighten capscrew. 2. DISASSEMBLY - These instructions apply to the series of pumps in general and may vary slightly on some units. If complete dissembly is not necessary, use only those steps which apply Due to the “back pull out” construction of these pumps, the frame and rotating assembly may be removed from the unit without removing the casing from the piping, or the driver from the base plate providing a spacer coupling is employed. a. Close valves in discharge and suction piping b. Remove coupling guard and shaft coupling per manufacturer’s instructions c.
