DESCRIPTION THERMAL SAFETY: The Series 2000 Frame Mounted Centrifugal Pump is an end suction centerline discharge pump. The Series 2000 Pump’s rear pull out construction makes servicing simpler and faster. The hydraulically balanced impellers extend bearing life and assure smoother, quieter operation. WARNING: Extreme Temperature Hazard If pump, motor, or piping is operating at extremely high or low temperature, guarding or insulation is required.
WARNING ROTATING COMPONENTS DISCONNECT AND LOCK OUT POWER BEFORE SERVICING. DO NOT OPERATE WITHOUT ALL GUARDS IN PLACE. CONSULT INSTALLATION AND SERVICE INSTRUCTION SHEET BEFORE OPERATING OR SERVICING. FAILURE TO FOLLOW INSTRUCTIONS COULD RESULT IN INJURY OR DEATH. (2) REQUIRED (1 EACH SIDE) CAUTION WARNING EYEBOLTS OR LIFTING LUGS IF PROVIDED ARE FOR LIFTING ONLY THE COMPONENTS TO WHICH THEY ARE ATTACHED. FAILURE TO FOLLOW INSTRUCTIONS COULD RESULT IN INJURY OR DEATH.
PUMP LOCATION Locate the pump so there is sufficient room for inspection, maintenance, and service. If the use of a hoist or tackle is needed, allow ample head room. WARNING Eyebolts or lifting lugs if provided are for lifting only the components to which they are attached. Failure to follow instructions could result in injury or death. If lifting of the entire pump is required, do so with slings placed as shown. (Fig.
INSTALLATION This pump is built to provide years of service if installed properly and attached to a suitable foundation. A base of concrete weighing 2-1/2 times the weight of the pump is recommended. (Check the shipping ticket for pump weight.) If possible, tie the concrete pad in with the finished floor. Use foundation bolts and larger pipe-sleeves to give room for final bolt location. (Fig.
ANSI/OSHA COUPLER GUARD REMOVAL/INSTALLATION GROUTING After the pump has been leveled, securely bolted to the floor, and properly aligned, a good grade of non-shrinking grout should be poured inside the pump base. To hold wedges or shims in place, allow the grout to flow around them. WARNING: Unexpected Start-up Hazard Disconnect and lock out power before servicing. Failure to follow these instructions could result in serious personal injury or death and property damage.
f. Position the outer guard so it is centered around the shaft, and so there is less than 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 1/4" of the pump shaft exposed. g. Holding the guard in this position, tighten the three capscrews.
Method 2- For Orange Hytrel Insert, 3500 Operation, or All Other Coupler Types Except as Noted Below (See Fig. 5B) Grid Couplings NOTE: The following procedure is intended for mounting and alignment of Rexnord Industries, LLC. and Clarke Fire Protection Products, Inc., Tapered Grid Couplings. a. Make sure each hub is secured to its respective shaft and that all connecting and/or spacing elements are removed at this time. Adequate lubrication is essential for satisfactory operation.
6. If adjustment is needed, loosen the motor bolts and add (or remove) equal amounts of shims under each motor foot, to align the height. To correct side misalignment, strike the side of the motor foot with a mallet. 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. 7. Pack gap and grooves with coupling vendor supplied grease before inserting grid.
8. Pack the spaces between and around the grid with as much as coupling vendor supplied grease as possible and wipe off the excess until flush with the top of the grid. Position seals on hubs to line-up with grooves in cover. Position gaskets on flange of lower cover half and assemble covers so that the match marks are on the same side. 9. Ensure lube plugs are installed in cover. CAUTION: Coupling Failure Do not operate coupling without proper lubrication. Coupling failure may occur.
WARNING: Coupling Failure Final Alignment Final alignment cannot be accomplished until the pump has been operated initially for a sufficient length of time to attain operating temperature. When normal operating temperature has been attained, secure the pump to re-check alignment and compensate for temperature accordingly. See Alignment Section. Do not operate pump with coupling out of alignment.
PRIMING AND STARTING CAUTION: Seal Damage Hazard Do not run pump dry, seal damage may occur. Failure to follow these instructions could result in property damage and/or moderate personal injury. LUBRICATION While pump is running, re-grease pump bearings with #2 lithium base petroleum grease after every 2500 hours of operation or every 6 months, whichever occurs first. Before starting the pump, the pump body must be full of liquid.
5. Remove the O-ring (2-914-0) from the stuffing box cover and inspect for damage. Replace if necessary. packing rings (6-924-0) and, where applicable, the seal cage (6-013-0) from the stuffing box. A standard packing hook is recommended for removing the pack and seal cage. IMPELLER REMOVAL 1. Lock the coupling end of the shaft in a padded vise. 4. Remove the packing base ring. FRAME DISASSEMBLY 1. Remove bearing caps (5-018-3 and 5-018-4). 2. Remove the impeller nut (4-023-0).
ASSEMBLY PROCEDURES bearing (5-026-4) seats firmly against snap ring (5-068-3) inside the outboard bearing housing. FRAME ASSEMBLY 1. Press the outboard bearing (5-026-4) onto the motor side of the pump shaft (5-007-0). 8. Place snap ring (5-068-4) in the outside snap ring groove of the outboard bearing housing (tapered edge away from bearing). NOTE: When pressing bearings onto the shaft, press only against the inner race. 9. Install bearing caps (5-018-3 and 5-018-4) onto both ends of the pump frame.
B. Pumps with Packed Stuffing Boxes 1. Slide deflector (1-136-0) onto the pump shaft. STUFFING BOX IMPELLER HUB 2. Slide the packing gland (6-014-0) onto the pump shaft (flat side toward frame). G 3. Slide the shaft sleeve (1-009-0) onto the pump shaft. To prevent leakage, use silicone sealant between the shaft and shaft sleeve. FIG. 7 “G” Setting Dimensions Shaft Sleeve OD G (inches) (inches) 1.25 1.22 1.62 1.31 2.0 1.38 4. Place the packing base ring (6-152-0) into the stuffing box.
6. Align the pump to the motor as instructed. 7. Connect the pump to the motor. Reinstall the coupling guard and drain plugs. Close drain valve. 8. Connect the power to the motor. CHECK THE MOTOR ROTATION. 9. Open isolation valves, inspect pump for leaks. If not leaking, return pump to service. NOTE FOR PACKED PUMPS: Final adjustment of the gland nuts must be done with the pump running. Allow 30 minutes between adjustments. Tightening the nuts too quickly can cause damage to the packing and sleeve.

ORDERING PARTS The pumps covered by this manual have been designed and built with certain replaceable wearing parts. The recommended inventory of spare parts depends upon the installation and the importance of continued operation. For critical service requiring a minimum of “down time” a complete or “quick change” rotating element is recommended. For normal service, with repairs to be made in the field, the following parts are recommended for stock.
