Observe the accident prevention regulations in force

Always refer to the local and/or national regulations, legislation and codes in force relating to the selection of the installation site and the water and power connections

1. SITE SELECTION

sure that no obstructions or obstacles hinder

Make the normal ﬂ ow of the cooling air delivered by the motor fan. Make sure there is adequate clearance around the pump for the maintenance operations. Whenever possible, raise the pump slightly from the level of the ﬂ oor. See the ﬁ gures below and at the top of the next column for possible installation conﬁ gurations. Horizontal operation requires special mounting with a horizontally conﬁ gured pump.

3. ANGULAR ALIGNMENT

Angular alignment of the suction and discharge ﬂ anges can best be accomplished using calipers at the bolt locations. See ﬁ gure below

NOTICE: DO NOT DRAW PIPING INTO PLACE BY

FORCING THE PUMP SUCTION OR DISCHARGE CONNECTIONS.

4. PIPING

Discharge and suction piping should be no smaller than the respective pump opening and should be kept as short as possible, avoiding unnecessary ﬁ ttings to minimize friction losses.

NOTICE: PIPING MUST BE INDEPENDENTLY SUP-

PORTED AND NOT PLACE ANY PIPING LOADS ON THE PUMP.

If suction piping larger than pump suction is required, an eccentric pipe reducer, WITH THE STRAIGHT SIDE UP, must be installed at the pump suction.

If the pump is installed below the liquid source, install a full ﬂ ow isolation valve in the suction piping for pump inspection or maintenance.

NOTICE: DO NOT USE THE ISOLATION VALVE

ON THE SUCTION SIDE OF THE PUMP TO THROTTLE PUMP. THIS MAY CAUSE LOSS OF PRIME, EXCESSIVE TEMPERATURES, DAMAGE TO PUMP AND VOID WARRANTY.

If pump is installed above the liquid source, the following MUST be provided:

To avoid air pockets, no part of the suction piping should be above the pump suction.

On any horizontal piping sections, slope piping upward from liquid source.

All suction pipe joints MUST be airtight. Use a foot valve for priming, or for holding

prime during intermittent duty.

The suction strainer or suction bell MUST be at least 3 times the suction pipe diameter.

Insure that the size and minimum liquid submergence, over the suction inlet, is sufﬁ cient to prevent air from entering through a suction vortex. See typical suction piping Figures 1 through 4.

Install a discharge check valve, suitable to handle the ﬂ ow and liquids, to prevent backﬂ ow.

Install an appropriately sized gate valve, AFTER the discharge valve, to regulate the pump capacity, for pump inspection and for maintenance.

When a pipe increaser is required, install between the check valve and the pump discharge.

5. SHAFT ALIGNMENT – MOTOR TO PUMP

When the pump is purchased less motor, the pump will be supplied with a motor assembly shim positioned between the motor adapter and the coupling.

To assemble the motor to the pump remove the plastic shipping straps, the 2 stainless steel coupling guard halves, and the expanded polyurethane.

Insure that the motor assembly shim is properly positioned between the coupling and the motor adapter. If the motor assembly shim is not available, a 0.203" (5 mm) shim may be used to locate the pump shaft assembly and to set the correct height. See ﬁ gures below.

Loosen the 4 coupling socket head screws enough to provide an adequate opening in the coupling to receive the motor shaft.

With an adequately sized crane, carefully lower the motor assembly onto the pump motor adapter and into the coupling. Secure the 4 motor hex cap screws, torquing to the value provided in the “EN- GINEERING DATA” section of this manual.

Torque the 4 coupling socket head screws to the value provided in “ENGINEERING DATA” section of this manual. After assembly, the gap between the coupling halves should be equal.

For the 33 through 92SV sizes using a cartridge seal, after coupling bolts have been properly torqued, there are four set screws on the collar of the cartridge seal that require tightening before removing the shim. The four hex head set screws require a 1/8" allen wrench and are to be tightened hand-tight approximately 5 lbs.-ft. (7 N•m).

Remove the motor assembly shim and retain for future use.

Install the 2 coupling guard halves.

1. WATER CONNECTION

The water connections must be made by qualiﬁ ed installation technicians in compliance with the regulations in force

In case of connection to the water system, the regulations issued by the competent authorities (municipal, public utility company) must be observed. Authorities often require the installation of a backﬂ ow prevention device, such as a disconnector, check valve or disconnection tank

2. WIRING AND GROUNDING

WARNING

Install, ground and wire according to local and National Electrical Code requirements.

NOTICE: UNIT ROTATION IS DETERMINED WHEN

VIEWED FROM MOTOR END. SEE PAGE 17 FOR MOTOR ROTATION DETAIL. INCORRECT ROTATION MAY CAUSE DAMAGE TO THE PUMP AND VOIDS WARRANTY.

Check pump rotation by observing the motor fan or the coupling THROUGH the coupling guard. DO NOT confuse the ﬂ ow arrows, stamped on the pump body, with the rotation arrows on the coupling and motor adapter. Three phase motors only – If rotation is incorrect, have a qualiﬁ ed electrician interchange any two of the three power cable leads.

Hazardous voltage can shock, burn or cause death.

Disconnect and lockout electrical power before installing or servicing pump.

Electrical supply MUST match pump’s nameplate speciﬁ cations. Incorrect voltage can cause ﬁ re, damage motor and voids warranty.

Motors equipped with automatic thermal protectors open the motor’s electrical circuit when an overload exists. This can cause the pump to start unexpectedly and without warning.

Use only stranded copper wire to motor and ground. Wire size MUST limit the maximum voltage drop to 10% of the motor nameplate voltage, at the motor terminals. Excessive voltage drop will affect performance and void motor warranty. The ground wire must be at least as large as the wires to the motor. Wires should be color coded for ease of maintenance.

Three phase motors require all leg protection with properly sized magnetic starters and thermal overloads.

WARNING

slide the assembly onto the pump shaft, spring end ﬁ rst. Be sure the seal face is towards the motor. DO NOT scratch or otherwise damage the seal face. With a clean, lint free cloth or alcohol swab, wipe the seal face clean of all lubricant or debris.

13. Lubricate the outside of the new mechanical seal

stationary element with a water based lubricant.

14. Insert the stationary seat into the seal housing with

the seal face out. DO NOT scratch or otherwise damage the seal face. Insure that the stationary seat is fully seated into the seal housing. With a clean, lint free cloth or alcohol swab, wipe the seal face clean of all lubricant or debris.

NOTE: Do not use grease or heavy oil as an installation lubricant. Any oil or grease on the seal faces may cause seal to leak.

15. With a new O-ring, install the seal housing onto

the pump shaft, seating the plate fully and squarely onto the pump outer shell.

16. Place the motor adapter over the 4 tie rod bolts,

using an adequately sized crane when required, and install the 4 lock washers and tie rod nuts. Torque the nuts, in sequence, to the value provided in the “ENGINEERING DATA” section of this manual.

17. With an adequately sized crane, carefully lower

the motor onto the motor adapter, lining up the electrical conduit connection and the 4 motor adapter bolt holes, as required.

18. Install the 4 motor hex cap screws, torquing to the value provided in the “ENGINEERING DATA” section of this manual.

19. Place the coupling drive pin into the pump shaft and install the coupling halves onto the motor and pump shafts. Install the 4 coupling socket head screws, lock washers and nuts, DO NOT tighten.

20. Position the motor assembly shim between the coupling and the motor adapter. If the motor assembly shim is not available, a 0.203" (5 mm) shim may be used to locate the pump shaft assembly and to set the correct height.

21. Tighten the 4 coupling socket head screws, torquing screws to values provided in the “ENGI- NEERING DATA” section of this manual. Tighten evenly so that the gap between the halves is equal side to side and top to bottom.

22. Install the 2 coupling guard halves.

1. Close all necessary suction and discharge valves to isolate the pump from the system.

2. Drain the liquid from the pump by removing the drain plug and opening the needle valve on the vent plug.

3. Remove the coupling guards, the 4 coupling hex cap screws, the coupling and coupling drive pin. See steps 1-3.

4. Remove the 4 motor hex cap screws (inner screws) on the seal housing. See step 4.

5. Remove the seal housing plate using the two tapped holes provided. Threading 2 of the hex cap screws into these holes and evenly tightening the screws. Lift and remove the seal housing between the pump and motor shaft. Exercise care when sliding the seal housing between the shaft to prevent damage to the stationary seat. See step 5.

6. Turn the seal housing upside down and remove the stationary seat and o-ring. Remove and discard the large o-ring used to seal the seal housing to the pump head. Inspect the seal seat for any burrs or debris. Make sure that the seat is clean. Lubricate the new o-ring for the seal seat with a

lubricant compatible with the o-ring and install the new seat by pressing it into the seal housing with your thumb. DO NOT USE EXCESSIVE FORCE and, if possible, place a clean soft cloth over the seal face to protect the seal faces during installation.

7. Remove the rotary portion at the mechanical seal

by sliding the rotary unit axially upwards along the pump shaft. Inspect the pump shaft for any burns or debris. Any burrs should be around

smooth with (ﬁ ne grit) emery paper. See step 7 in Figure 5.

8. Lubricate the o-ring located in the ID of the rotary unit of the mechanical seal with a lubricant compatible with the seal elastomers. Carefully slide the rotary unit of the mechanical seal down the shaft. Rotate the seal to locate the pin on the bottom of the seal with the holes in the shaft sleeve. Cycle seal up and down to lubricate o-ring and prevent seal from sticking to shaft. See step 8 in Figure 5.

Figure 5

9. Install a new seal housing o-ring on the seal hous-

ing. A lubricant can be used to hold the o-ring on the diameter of the seal housing.

Carefully reinstall the seal housing between the pump and motor shaft and slide the seal housing down the shaft into position. Use caution when

mounting the sealhousing between the pump/motor shaft so that the seal face on the stationary seat is not damaged.

See step 9 in Figure 5.

10. Reinstall the 4 hex cap screws, tightening

the screws evenly and then torquing them to the values given in the engineering data. See step 10 in Figure 5.
