4.1 Preinstallation Baseplate Shims or wedges Foundation Sleeve Bolt Figure 6: Build dam around foundation Pour grout through the grout holes in the sub-base, up to level of dam. Remove air bubbles from grout as it is poured by puddling, using a vibrator, or pumping the grout into place. Non-shrink grout is recommended. - Page 22 4.1 Preinstallation The following is a brief description of the spring pocket components and their function (see Figure: Spring pocket components). The adjusting screw is used to compress or relax the spring. Turning the screw causes the adjusting screw nut assembly to move vertically and change the amount of force the spring exerts against the spring retainer, which is fastened to the sub-base.
- Page 23 4.1 Preinstallation Place blocks under the sub-base, near each spring holder, and position the sub-base level on the blocks. A small gap (approx. 1.6 mm | 1/16") should exist between the flange of the vertical pipe and the pump elbow with the gasket in place (see Figure: Blocks placed under sub-base). Install several flange bolts to help maintain alignment of the flanges.
-
Page 24: Remove Spring From Spring Pocket
4.1 Preinstallation Check the alignment of the impeller and the pump elbow. If necessary, correct the alignment by ad- justing the springs or by using shims. NOTICE: If the flange gap is over 0.8 mm | 1/32", turn the adjusting screws a uniform amount to close the gap. -

Page 27: Pipe Hung Installation
4.3 Pipe Hung Installation valve prevents pump or seal damage due to reverse flow through the pump when the driver is turned off. Increasers, if used, should be placed between pump and check valves. Cushioning devices should be used to protect the pump from surges and water hammer if quick- closing valves are installed in system. -
Page 28: Drive Alignment Procedures
4.4 Drive Alignment Procedures After the grout has hardened, tighten the anchor bolt nuts. Check and correct the motor shaft alignment. We recommend the actual shaft misalignment for the flexible couplings be considera- bly less than the maximum allowed by the coupling manufacturer for long coupling life and re- duced vibration levels. -
Page 29: V-Belt Drive (Sheaves)
4.4 Drive Alignment Procedures NOTICE: Proper alignment is the responsibility of the installer and user of the unit. Trouble free operation can be accomplished by following these procedures. Initial Alignment (Cold Alignment) • Before Grouting Sub-base - To ensure alignment can be attained. After Grouting Sub-base - To ensure no changes have occurred during the mounting process. - Page 30 4.4 Drive Alignment Procedures Check Belt Fit - Regardless of the belt section used, the belt should never be allowed to bottom in the groove. This will cause the belts to lose their wedging action and slippage can occur. Sheaves or belts that permit such a condition to occur should be changed. Maintain Proper Belt Tension - Proper tension is essential for long belt life.
-
Page 31: Gear Drive (Couplings)
4.4 Drive Alignment Procedures If any questions arise pertaining to the drive limitations, consult the manufacturer. 4.4.2 Gear Drive (Couplings) NOTICE: The coupling used in an ATEX classified environment must be properly certified. Remove the guard or guards by referring to the assembly/disassembly instructions. Disconnect motor/ gearbox and the pump/gearbox coupling halves before proceeding with the alignment. - Page 32 4.4 Drive Alignment Procedures Alignment Procedure On gear driven AF pumps angular and parallel misalignment are corrected in the vertical direction by means of shims under the motor or gearbox mounting feet, and in the horizontal direction by adjusting bolts that slide the motor or gearbox in the proper direction. After each adjustment, it is necessary to recheck the alignment of the coupling halves.
- Page 33 4.4 Drive Alignment Procedures Record the largest gauge size that fits snugly between the two flanges. Rotate both flanges to position 3 - 180° Insert a feeler gauge at the periphery of the couplings at position 3. Record the largest gauge size that fits snugly between the two flanges. Calculate the difference between the readings at positions 1 and 3.

Remove the V-belt guard. Make sure the sheaves are securely fastened to shafts. Unlock driver power. Make sure everyone is clear. Jog the driver just long enough to determine direction of rotation. Rotation must correspond to an arrow on bearing housing.
- Page 40 5.1 Preparation for start-up An oil with a higher viscosity than required will increase the bearing operating temperature because of the extra viscous drag, but never to the point where the viscosity becomes lower than required from the increased heat generation. It is therefore better for the bearings to have an oil that is too heavy rather than too light.
- Page 41 5.1 Preparation for start-up Packed stuffing box The original equipment packing is a suitable grade for the service intended. To pack the standard stuffing box use the following procedure: For the special (6) ring packing arrangement see Bearing alignmentThe bearing alignment collar is used to install the radial bearing on the 4MXR, 5MXR, and 6MXR bearing configurations.

Page 42: Start The Pump
5.2 Start the Pump Leakage Normal leakage for a properly adjusted box, depending on shaft size and speed, varies from a few drops a second to a small trickle out of the gland. Mechanical seal The mechanical seal used in an ATEX classified environment must be properly certified. The mechanical seal must always be properly flushed. - Page 43 5.2 Start the Pump WARNING: If pump becomes plugged, shut down pump and unplug prior to restarting. CAUTION: Foreign objects in the pumped liquid or piping system can block the flow and cause ex- cess heat generation, sparks and premature failure. Make sure that the pump and sys- tems are free of foreign objects before and during operation.

Page 44: Operation
5.3 Operation CAUTION: Risk of equipment damage due to dry operation. Immediately observe the pressure gauges. If discharge pressure is not quickly attained, stop the driver immediately, reprime, and attempt to restart the pump. Set desired flow If your system is equipped with a variable frequency drive (VFD) or a variable speed V-belt drive, you may at this point want to set your speed for the desired flow. - Page 45 5.3 Operation While field conditions preclude absolute accuracy, a check of pump performance will give reason- ably close results. This can be done by installing a mercury manometer at pipe taps located at least-one pipe diameter away from the suction and discharge flanges of the pump. If-gauges are used, the pressure differential times 2.31 divided by the specific gravity of the slurry indicates the TDH against which the pump is actually operating.

Page 78: Special Packing Arrangement
9 Appendix I 9 Appendix I 9.1 Special Packing Arrangement (High pressure, dual flush packing) The following information covers the installation, operation and maintenance of the high pressure, dual flush packing arrangement. This arrangement was developed for high pressure, to minimize product dilu- tion, and to minimize external packing leakage. - Page 79 9.1 Special Packing Arrangement The flush pressures should be 10% higher than the pressure inside the pump. For end suction pumps this will also include pump discharge pressure. Product flush pressure to the inner lantern ring may be slightly less than the water flush pressure to ensure flow toward the inside of the pump. The flush flow depends on the application, the more heat generated the higher the flows must be to ef- fectively remove the heat.
- Page 80 9.1 Special Packing Arrangement Correct Incorrect Figure 29: Packing Rings Expand the first coil as shown and insert into stuffing box. Tamp the packing up against the re- strictor bushing shoulder firmly with a nylon bar or wood rod. Note, where the cut is positioned. Assemble the first lantern ring around the shaft and push it squarely into the stuffing box until it bottoms out against the first ring of packing.
