Using ANSI/OSHA Standard “S” hooks, place the “S” hooks in the holes provided in the four corners of the base. Be sure the points of the hooks do not touch the bottom of the pump base. Attach nylon slings, chains, or wire rope to the “S” hooks. Size the equipment for the load, and so the lift angle will be less than 45° from the vertical. DO NOT LIFT ENTIRE PUMP WITH THESE LUGS. Bases supplied without lifting holes Place one sling around the outboard bearing housing.
Full Pedestal (Model 300) 2. Install eyebolts in the three holes provided at the top of the support, being sure to tighten securely. Attach chain or wire rope using latch hook or standard shackle and end loop. Be sure to use shoulder eyebolts that are manufactured per ANSI B18.15 and sized to fit the holes provided. Be sure lifting equipment is of sufficient length to keep the lift angle less than 30° from the vertical. (See Fig. 7) Fig. 7 3 STORAGE The following storage procedures apply to the pump only.
LOCATION The pump should be installed as near the suction supply as possible, with the shortest and most direct suction pipe practical. The total dynamic suction lift (static lift plus friction losses in suction line) should not exceed the limits for which the pump was sold. The pump must be primed before starting. Whenever possible, the pump should be located below the fluid level to facilitate priming and assure a steady flow of liquid. This condition provides a positive suction head on the pump.
NOTE: The baseplate does not have to be level. After foundation bolts are lightly torqued, recheck alignment requirements once more. Follow requirements outlined at the beginning of this section. If alignment must be corrected, add or remove shims or wedges under the baseplate. The unit can then be grouted. (See Fig. 9) Grout compensates for the uneven foundation.
taken with the pump and driver bolts tightened. Final alignment check should be made after the unit has attained its final operating temperature. Method 1 - Using straight edge and taper gauges or feelers (Fig. 10): Proceed with this method only if satisfied that face and outside diameters of the coupling halves are square and concentric with the coupling bores. If this condition does not exist or elastomeric couplings do not make this method convenient, use Method 2.
Fig. 11 DOWELING Pump units may, if desired, (or required in specification) be doweled on diagonally opposite feet. This should not be done until the unit has been run for a sufficient length of time and alignment is within the above alignment tolerance. SUCTION AND DISCHARGE PIPING The introduction of pumpage into a piping system which is not well designed or adjusted may cause strain on the pump, leading to misalignment or even impeller rubbing.
Suction Piping When installing the suction piping, observe the following precautions. (See Fig. 13) The sizing and installation of the suction piping is extremely important. It must be selected and installed so that pressure losses are minimized and sufficient liquid will flow into the pump when started and operated. Many NPSH (Net Positive Suction Head) problems can be directly attributed to improper suction piping systems.
Discharge Piping If the discharge piping is short, the pipe diameter can be the same as the discharge opening. If the piping is long, the pipe diameter should be one or two sizes larger than the discharge opening. On long horizontal runs, it is desirable to maintain as even a grade as possible. Avoid high spots, such as loops, which will collect air and throttle the system or lead to erratic pumping. A check valve and an isolating gate valve should be installed in the discharge line.
STUFFING BOX LUBRICATION Contaminants in the pumped liquid must not enter the stuffing box. These contaminants may cause severe abrasion or corrosion of the shaft, or shaft sleeve, and rapid packing or mechanical seal deterioration; they can even plug the stuffing box flushing and lubrication system. The stuffing box must be supplied at all times with a source of clean, clear liquid to flush and lubricate the packing or seal.
When contaminants are present in the pumpage, an external source of clean seal water must be supplied. Supply approximately .25 GPM at a pressure approximately 15 to 20 psig above the suction pressure. Fig. 14 shows the recommended “Controlled Pressure System” for a mechanical seal. Seal water enters the seal chamber, lubricates the seal face, and exits into the pump itself. Positive flow in the seal water line indicates adequate seal water pressure. Pump Casing Fig.

All drains should be closed when filling the system. Filling should be done slowly so that excessive velocities do not cause rotation of the pumping elements which may cause damage to the pump or its driver. The adequacy of the anchors and hangers may be checked by mounting a dial indicator off of any rigid structure not tied to the piping and setting the indicator button on the pump flange in the axial direction of the nozzle.
SHUTDOWN The following steps will take care of most normal shutdowns of the pump, i.e. maintenance. Make any further adjustments of process piping, valves, etc., as required. If the pump is to be removed from service for an extended period of time, refer to the sections on storage and freeze protection. 2. Close suction and discharge valves. 1. Shut down the driver. (Consult manufacturer’s instructions for special operations.) 4. Open drain valves as required. 3. Close seal liquid valves.

Check alignment of pump and driver. Shim up units if necessary. If misalignment reoccurs frequently, inspect the entire piping system. Unbolt piping at suction and discharge flanges to see if it springs away, thereby indicating strain on the casing. Inspect all piping supports for soundness and effective support of load. Correct as necessary. EVERY YEAR Remove the upper half of the casing. Inspect the pump thoroughly for wear, and order replacement parts if necessary. Check wear ring clearances.
cavity between the bearing and grease fitting. Any greater amount will, as a rule, be discharged by the seal or vent and be wasted. The importance of proper lubrication cannot be over emphasized. Lubrication frequency depends upon the speed, size and type of bearing, and operating temperature or environmental conditions. Generally, the smaller the bearing and faster the speed, the more frequent the interval for relubrication with grease.
In installations with moderate temperature changes, low humidity, and a clean atmosphere, the oil should be changed after approximately 1000 hours of operation. The oil should be inspected at this time to determine the operating period before the next oil change. Oil change periods may be increased up to 2000-4000 hours based on an 8000 hour year. Check the oil frequently for moisture, dirt or signs of “breakdown”, especially during the first 1000 hours.
If your pump is supplied with seal cages (optional) make sure they are properly located in the stuffing boxes under the sealing water inlets. The function of the seal cage is to establish a liquid seal around the shaft, prevent leakage of air through the stuffing box and lubricate the packing. If it is not properly located it serves no purpose. MECHANICAL SEALS General instructions for operation of the various mechanical sealing arrangements are included below.
TROUBLE SHOOTING Between regular maintenance inspections, be alert for signs of driver or pump trouble. Common symptoms are listed below. Correct any trouble immediately and AVOID COSTLY REPAIR AND SHUTDOWN. Problem No Liquid Delivered Items Probable Cause Remedy 1 Lack of prime. 2 Loss of prime. Fill pump and suction pipe completely with liquid. Check for leaks in suction pipe joints and fittings; vent casing to remove accumulated air. Check mechanical seal or packing.
Problem Item Probable cause Remedy Pump Operates For a Short Time, Then Stops 30 Insufficient NPSHA. See item 17 31 System head too high. See items 4 & 10. 32 Head lower than rating; thereby pumping too much liquid. Machine impeller’s O.D. to size advised by factory, or reduce speed. 33 34 Cavitation. Mechanical defects. See item 17. See items 18, 19, 21, and 23. 35 Suction inlet not immersed. Liquid heavier (in either viscosity or specific gravity) than allowed for. See item 20.
