INSTALLATION

GENERAL. The life of your Aurora® pump can be extended considerably by carefully following the installation instructions contained herein. Each step of the pump installation instructions plays a vital part in assuring long life, efficient operation and reduced maintenance, from the initial location of the pump through prestarting directions.

UNPACKING YOUR PUMP. The crate containing your pump should be opened immediately upon receipt from the factory, and the pump generally inspected for damage and shortage of parts. Particular attention should be given to the discharge and suction nozzle threads or flanges. Any damage or shortage of parts should be reported to the carrier immediately.

PLANNING THE PUMP LOCATION. You probably have spent considerable time planning where your pump will be located. However, you may have overlooked some factor that may affect pump operation or efficiency.

The pump should be located as close to the liquid source as possible so that the suction line can be short and direct. It should be located in a clean, open area, where it is easily accessible for inspection, disassembly and repair. Pumps installed in dark, dirty areas or in cramped locations are often neglected, which can result in premature failure of both the pump and the driver.

Warning: Electrical Shock Hazard

All electrical connections are to be made by a qualified elec-trician in accordance with all codes and ordinances. Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: Electrical Overload Hazard

Ensure all motors have properly sized overload protection.

Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: Sudden Start-up Hazard

Disconnect and lock out power source before servicing.

Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: Hot Surface Hazard

If pumping hot water, ensure guards or proper insulation is installed to protect against skin contact to hot piping or pump components. Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: Spraying Water Hazard

When servicing pump, replace all gaskets and seals. Do not reuse old gaskets or seals. Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: High Pressure Hazard

The pump is rated at a maximum of 175 psi at 150°F.

Do not exceed this pressure. Install properly sized pressure relief valves in system. Failure to follow these instructions could result in serious personal injury, death or property damage.

Warning: Expansion Hazard

Water expands when heated. Install properly sized thermal expansion tanks and relief valves. Failure to follow these instructions could result in serious personal injury, death or property damage.

California Proposition 65 Warning:

This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

FOUNDATION. The foundation for your pump must be sufficiently rigid to absorb any vibration and stress encountered during pump operation. A raised foundation of concrete is preferable for most floor mounted pumps. The raised foundation assures a satisfactory base, protects against flooding, simplifies moisture drainage, and facilitates keeping the area clean.

Your pump should be firmly bolted to the foundation, whether it is a raised concrete base, steelwork wall, or structural member.

The mounting bolts or lag screws should be accurately located per the applicable Aurora® dimension sheet. Refer to Fig. 1.

LEVELING THE PUMP. Leveling the pump will require enough shims to support the baseplate near the foundation bolts and at any points of the baseplate carrying a substantial weight load. The shims should be large enough to allow a gap of 3/4" to 1-1/2" between the baseplate and foundation for grouting.

INITIAL ALIGNMENT OF THE FLEXIBLE COUPLING.

The pump and driver were accurately aligned at the factory.

However, it is impossible to maintain this alignment during shipping and handling. Therefore it will be necessary for you to realign the pump and driver. Flexible couplings are not universal joints. They should not be used to compensate for misalignment of the pump and motor shafts. Their function is to transmit power from the driver to the pump while compensating for thermal expansion and shaft end movement. The coupling faces should be far enough apart so that they do not make contact when the motor shaft is forced to the limit of the bearing clearance toward the pump shaft.

In order to properly align the coupling, you will need a taper gauge or set of feeler gauges and a straight edge.

There are two types of misalignment encountered with flexible couplings: angular misalignment, in which the shafts are not parallel, and parallel misalignment where the shafts are parallel but not on the same axis.

To check angular alignment, insert a feeler gauge or taper gauge at any four places 90° apart around the coupling halves. Insert shims under the driver feet until the same reading is obtained at all four checkpoints. The pump and driver will then be in angular alignment.

To check parallel alignment, a straight edge should be held against the edges of the coupling halves at any four places 90° apart around the coupling. The straight edge should be parallel to the pump and driver shafts at all times. Insert shims until the straight edge lies flat against both coupling halves at all four checkpoints. The pump and driver will then be in proper parallel alignment. Refer to Fig. 2.

SUCTION PIPING. The suction piping should be short, but no less than ten pipe diameters in length, and direct with as few elbows and fittings as possible to keep head loss, from friction, at a minimum. However, the suction pipe should provide a minimum uninterrupted length, equal to ten pipe diameters, to the pump suction flange. A horizontal suction line should have a gradual rise to the pump and pass under any interfering piping.

The suction pipe diameter should be at least the same diameter as the suction nozzle on the pump, and preferably larger. Use of a smaller diameter pipe will result in loss of head due to friction. All joints must be tight to maintain prime on the pump.

REDUCERS. Eccentric reducers should be installed directly at the suction nozzle, with the taper at the bottom to prevent air pockets from forming. Straight taper reducers should never be used in a horizontal suction line because of the air pocket that is formed at the leg of the reducer and the pipe. Refer to Fig. 3.

ELBOWS. Long radius elbows should be used in place of standard elbows wherever possible because of their superior flow characteristics. For instance, head loss in a standard four inch elbow is equivalent to the head loss in a piece of pipe 11 feet long, while the head loss in a long radius elbow is approximately half as much. Elbows should not be used at the suction nozzle, but if it is unavoidable, they should be installed in a vertical position. Elbows installed in any position at the suction nozzle have a tendency to distribute the liquid unevenly in the impeller chamber, causing a reduction in capacity, and creating an undesirable thrust condition. Refer to Fig. 4.

GROUTING THE INSTALLATION. Grouting the baseplate prevents lateral movement of the baseplate and improves the vibration absorbing characteristics of the foundation by increasing its mass. A wooden dam should be constructed around the baseplate to contain the grout while it is being poured. The dam can be built tight against the baseplate or slightly removed from it as desired.

The entire baseplate should be completely filled with a non-shrinkable type grout. The grout should be puddled frequently to remove any air bubbles from the grout.

DISCHARGE PIPING. Discharge piping should also be short and direct as possible, with few elbows and fittings, to reduce head loss from friction.

PIPE. The discharge pipe diameter should be the same as, or larger than, the discharge nozzle diameter. The size of discharge pipe to be used is dependent upon the application.

DISCHARGE VALVES. The discharge piping should include a check valve and a gate valve. The check valve should be located between the gate valve and the pump. If an increaser is used in the discharge piping, the increaser should be installed between the pump nozzle and the check valve. The check valve protects against a reverse flow of the liquid if the driver fails. Refer to Fig. 5.

The gate valve is used in the priming operation, as a throttling valve to control pump volume and to shut down the pump for inspection and maintenance.

ELECTRICAL WIRING. Normally, your pump will be sup-plied with an attached drive motor. The motor should be wired in accordance with the wiring diagram found on the motor nameplate. Be sure the voltage, frequency and phase of your power supply corresponds with the nameplate data. It is advisable to provide a separate switch and overload protection for your pump motor to protect against power failure in some other area. Conversely, if the pump motor develops electrical problems, it will be isolated from other equipment.

PRESTARTING INSTRUCTION. The coupling halves should be connected. Prior to connection, however, the drive motor should be started to make sure the direction of rotation is the same as the direction indicated by the arrow on the pump casing.

Do not operate the pump without liquid. Pump seals or packing depend on the liquid being pumped for lubrication.

Be sure the pump is primed and that no air exists in the suction pipe and pump casing.

MAINTENANCE

Your Aurora® pump requires no maintenance other than periodic inspection, lubrication and occasional cleaning. The intent of inspection is to prevent breakdown, thus obtaining optimum service life. The motor may require lubrication. The motor manufacturer’s recommendation should be followed. For all of the split case pump models, regreasable bearings are standard. Oil lubrication is optional on the 431B pumps.

Regreasable bearings will require periodic lubrication and can be accomplished by using the zerk or lubrication fittings in the cartridge cap. Lubricate the bearings at regular intervals using a grease of high quality. Aurora recommends Chevron SRI No. 2 grease with a polyurea thickener. However, most major brands of Grade No. 2 ball bearing grease are satisfactory for pumps oper at ing in both wet and dry locations. Mixing of different brands of grease should be avoided due to possible chemical reactions between the brands which could damage the bearings.

Accordingly, avoid grease of vegetable or animal base which can develop acids, as well as grease containing rosin, graphite, talc and other impurities. Under no circumstances should grease be reused.

Overlubrication should be avoided as it may result in overheating and possible bearing failure. Under normal application, adequate lubrication is assured if the amount of grease is maintained at 1/3 to 1/2 the capacity of the bearing and adjacent space surrounding it.

In dry locations, each bearing will need lubrication at least every 4,000 hours of running time or every 6 to 12 months, whichever is more frequent. In wet locations the bearings should be lubricated at least after every 2,000 hours of running time or every 4 to 6 months, whichever is more frequent. A unit is considered to be installed in a wet location if the pump and motor are exposed to dripping water, to the weather, or to heavy condensation such as is found in unheated and poorly ventilated underground locations.

Oil lubricated bearings are optional on Model 431B pumps. A fixed oil level is maintained with the bearing cartridge by an oiler which allows visual indications of reserve oil.

At initial installation and before starting, a unit that has been shut down for repairs or for any extended length of time, run enough 10W-20 weight motor oil through the oiler to maintain a constant oil level to ensure that the bearing will never be without an oil supply. Oil will have to be added at intervals to maintain a constant level in the oiler. This interval can be determined only by experience.

Under working conditions, oil will break down and need to be replaced at regular intervals. The length of these intervals will depend on many factors. Under normal operation, in clean and dry locations, the oil should be changed about once a year.

However, when the pump is exposed to dirt contamination, high temperatures (200°F or above) or a wet location, the oil may have to be changed every 2 to 3 months.

At times it may be necessary to clean the bearings due to accumulated dirt or deteriorated lubricants. This can be accomplished by flushing the bearing with a light oil heated 180 to 200ºF while rotating it on a spindle.

Wipe the bearing housing with a clean rag soaked in a cleaning solvent and flush all surfaces.

Dry bearing thoroughly before relubricating. Compressed air can be used to speed drying, but care should be taken not to let bearings rotate while being dried.

Use normal fire caution procedures when using any petroleum cleaner.

The motor that drives your Aurora pump may or may not require lubrication. Consult the manufacturer’s recommendations for proper maintenance instructions.

REPAIRS

The pump may be disassembled using the illustrations and text provided. Although complete disassembly is covered, it will seldom be necessary to completely disassemble your Aurora pump.

The illustrations accompanying the disassembly instructions show a Model 411 pump at various stages of disassembly. The illustrations are intended to aid in the correct identification of the parts mentioned in the text.

Refer to Figure 6 that illustrates the various pump models described in this manual.

Inspect removed parts at disassembly to determine if they can be reused. Cracked castings should never be reused. All optional packing and gaskets should be replaced at reassembly simply as a matter of economy. They are much less expensive to replace routinely than to replace singly as the need arises. In general it is economical to return to the manufacturer for repair to the motor and motor controller.

DISASSEMBLY

Disassemble only what is needed to make repairs or accomplish inspection. Proceed to disassemble the pump as follows:

CAUTION

6. Scribe a mark on shaft sleeves for relocating seal collar on reassembly. Loosen setscrews (55), securing seal collars

(54) to shaft sleeves and slide them off.

7. Proceed with further disassembly of outboard ball bearing and seal assembly using same basic procedure.

8. After removal of mechanical seals, proceed with balance of disassembly in the same manner as described for pack-ing design.

Figure 11. Outboard rotating element components removed, illustrating disassembly.

Figure 12. Sleeve and O-ring removed.

CAUTION

REASSEMBLY

Reassembly will generally be in reverse order of disassembly.

If disassembly was not completed, use only those steps related to your particular repair program.

1. Position locating pins (67) in lower casing (69), adding swing bolt pins (68), if used on your pump. Install wearing ring pins (66). Tap pins gently to seat them in place. If nameplate (71) was removed, install it with screws (70).

Install O-ring (58) in shaft sleeve (64).

2. On a right-hand unit, thread inboard sleeve (64) onto shaft

(65) distance A (refer to figure 14) based on pump size. On a left-hand unit, thread outboard sleeve (57) onto the shaft a distance A (refer to figure 15). When the sleeve is in posi-tion its keyway should align with keyway on shaft. Coat key and keyway with Loctite® Sealant Grade 242. Insert key

(63) into keyways of shaft and sleeve. Tap it firmly in place.

3. Coat inside diameters of impeller wearing rings (61) (optional) with Loctite Sealant Grade 271 and press them over hubs of impeller (59). Do not attempt to hammer impeller wear rings into position, since they are a press fit. Use of an arbor press is preferred. However, placing a block of wood over the impeller wearing ring and pressing it in will work satisfactorily. For power frames 5, 6B and 7 only, two setscrews (78) will be installed by drilling into wearing rings and impeller. The opposite surface of the impeller should be protected from damage throughout the procedures by resting it against soft wood on the surface of work bench.

Impeller wearing rings must be given special care be-cause they are press fit. Be sure rings are positioned squarely over hubs of impeller. A soft headed hammer may be used to gently tap impeller wearing rings into correct alignment before they are pressed into place.

4. Coat impeller (59) keyway with Loctite Sealant Grade 242 and slide onto shaft until it is firmly against the shaft sleeve.

Place O-ring (58) in shaft sleeve (57) and thread shaft sleeve firmly against the impeller.

NOTE

When assembling rotating element of a 410 Series pump, it is important that the curve of the impeller blades is in agreement with pump rotation. Refer to impeller rotation sketches, Figs. 22–24.

Carefully check that proper shaft sleeve has been keyed into place for rotation of pump. If correct shaft sleeve is not keyed onto shaft, it can spin loose during operation of pump and cause excessive damage.
