IMPORTANT INFORMATION - READ ME FIRST Model Number and Serial Number Record the model number and serial number below for future reference. This is important information when ordering replacement parts or when technical assistance is required. The numbers are found on a label located on the motor adapter.

OUT CAUSING DAMAGE TO THE PUMP. However, the pump can operate without liquid in the casing if the pump has a carbon bushing. The exact length of time the pump can operate dry with a carbon bushing varies with operating conditions and environment. CAUTION: Never start or operate with a closed suction valve. Never operate with a closed discharge valve. CAUTION: Always provide adequate NPSHa (net positive suction head available).
DB11/15 ASSEMBLY, INSTALLATION & OPERATION Unpacking and Inspection Unpack the pump and examine for any signs of shipping damage. If damage is detected, save the packaging and notify the carrier immediately. Section I - Assembly NOTE: Make sure the motor shaft is clean and free of burrs. The outer drive is precision machined and has a bore tolerance of +.0005/-0 inch. 5.
Install the pump end on the motor/drive magnet assembly. With ` (3) Use the shorter M6 bolts, lock washers and flat washers (items 24, 25 and 26) for the rear bolt holes towards the the motor facing upright, align the pump feet so that the motor face. Note: Nuts (item 30) are glued into the rear motor feet and pump feet are on the same side. the motor adapter to help with the installation of the rear bolts. Make sure the nuts are still in place.
• FTI advises installing a flush system in the piping to allow the pump to be flushed before it is removed from service. NOTE: The pump is provided with a provision for a customer installed ¼” drain in the impeller housing. See the Drain Installation Section for details. • For units in a suction lift system, install appropriate piping in the discharge to allow priming of the pump (DB11/15 models are not self-priming).
Section V - Disassembly tors 3 HP (2.2 kW) or larger, place the pump and motor on the floor. Remove the (4) bolts, lock washers and flat washers (items 15,16,17) securing the pump to the mo- tor. See figure 9. Make sure the motor is on the fan end with the pump facing up. Pull straight up to remove the pump from the motor. See figure 12. WARNING: Rotating Parts. This pump has components that rotate while in operation.
Check the impeller thrust ring and bushing for wear. See figure 16. Figure 19 3. To reinstall the drive or a new drive follow the instructions from Section I - Assembly, Pumps without Motors, steps 4-6. Figure 16 6. Remove the impeller shaft (item 6) from the barrier and check for signs of cracking, chipping, scoring or wear. See figure 17. Thrust Ring Replacement 1. Thrust ring (item 4A) is held in-place with a snap fit with a ridge.
Impeller Replacement Caution: Do not damage the outer surface of the inner drive magnet during impeller replacement. Using the two slots provided, insert a flat blade screw driver into them and pry the impeller (items 4, 4A) up from the Figure 30 body of the inner drive magnet (items 5, 5A). Once a gap has 4. Install the new clamp ring. Place the clamp ring on a flat surface. been established, work around the perimeter to evenly increase See figure 31.
7. Install o-ring (item 2). See figure 39. 8. Install impeller shaft (item 6) into barrier by aligning the flats on the shaft with the ones in the barrier. Make sure it is completely seated. See figure 39. Figure 39 9. Carefully install the impeller/inner drive assembly (items 4, 4A, 5, 5A) by sliding it over the impeller shaft in the barrier. It is normal for the impeller /inner drive to pop up a slight amount due to magnetic forces. See figures 40 and 41. Figure 41 Figure 40 10.

Section VII - Troubleshooting General Notes: • Do not pump liquids containing ferrous metal fines. • If magnets decouple, stop pump immediately. Operating the pump with the magnets decoupled will eventually weaken the magnets. • Power monitors are required and must be used with all ATEX certified pumps. • Do not use mismatched drive magnet assemblies (different number of magnets on inner and outer drive magnet assemblies).
