Model 45HB-70HB

MULTI-STAGE CENTRIFUGAL BOOSTER PUMP

INSTALLATION, OPERATION AND TROUBLESHOOTING MANUAL

GENERAL INFORMATION

GENERAL INFORMATION

Models 45HB and 70HB are multi-stage, high-pressure,
general-purpose centrifugal booster pumps, using en­closed impellers. Applicable for clear, non-hazardous
liquids in general industrial services up to 180°F (82°C).
Particularly suited for high-pressure booster services.

All models are close-coupled to electric motors contain­ing prelubricated bearings designed for continuous ser­vice. Threaded shaft extension is protected by a stainless
steel sleeve/coupling combination.

All models are equipped with single, unbalanced mechan­ical shaft seals.

Units are shipped completely assembled and ready for
installation.

IMPORTANT

IMPORTANT

1. Inspect unit for shipping damage.

2. Read all instructions carefully.

3. ALWAYS disconnect all electrical power when han­dling pump, motor, or controls.

4. Do not run unit dry or against a closed discharge.
This will result in damage to mechanical seal and
pump.

5. Never pump hazardous liquids or solvents.

6. Maximum liquid temperature: 180°F (82°C).

7. Maximum inlet pressure: 100 PSI.

INSTALLATION

INSTALLATION

Location: Locate pump as near the liquid source as prac-

tical. Allow adequate room for servicing and ventilation.
Protect the unit from cold weather freezing and water
damage due to rain or flooding. Pump may be mounted
horizontal; or vertical with motor on top provided a
drip-shield is used for motor protection.

Foundation: Foundation surface must be flat so there is
no distortion and/or strain developed when tightening
the foundation bolts. CAUTION: Bolting and/or piping
must not put strain on liquid end. The pumps are quiet
and smooth running, but rubber mounting is recom­mended on foundations susceptible to sound effect.

Alignment: No filed alignment is necessary as pumps are
close-coupled.

Piping: Suction pipe must be at least equal in size to
suction connection of pump and provide positive suc­tion head (intake pressure) to the pump. Avoid using the
pump for applications requiring suction lift. Never use a
gate valve in the suction line to throttle the pump. CAU­TION: Piping must not put strain on the liquid end.

Wiring: Electrical power supply must be a separate
branch circuit equipped with proper starters, fuses or
circuit breakers, wire size, etc., conforming to National
Electrical Code plus local codes. Power supply voltage,
phase and controls must match motor nameplate require­ments. Low voltage and phase-loss (3 phase) protection is
recommended.

Motors: Single-phase 3 HP motors are dual voltage
115/230 volts, 60 Hz, A.C. Single-phase 5 HP motors are
230 volts, 60 Hz, A.C. All other motors are three-phase,
dual voltage 230/460 volts, 60 Hz, A.C. The higher volt­ages are recommended where available.

Rotation: Three-phase rotation must be checked at instal­lation my momentarily energizing the completely filled
pump and observing the rotation. Rotation is clockwise
looking into the motor shaft, end-bell side (remove pro­tective cap to observe shaft). Rotation must correspond
to rotation arrow. Rotation of three-phase units can be
reversed by interchanging any two (2) electrical power
leads. CAUTION: Do Not run in reverse rotation or
damage will result.

OPERATION

OPERATION

Fill suction line and pump with liquid to be pumped to
insure mechanical seal will not run dry. With pump and
suction line completely filled, and motor properly wired,
the unit may be started. Be sure pump is not started
against a closed valve in the discharge line.

MAINTENANCE

MAINTENANCE

1. Lubrication

Pumps should require no maintenance other than the
motor bearings: In hot or severe service, lubricate
every 3 months. Follow motor manufacturer’s instruc­tions to determine lubrication schedule. Lubricate with
power off and motor warm. Remove upper and lower
plugs at both bearing. Free lower relief hole of hard
grease. Install clean grease-fitting on upper hole and
add grease with a low-pressure grease gun. Run motor
30 minutes. Stop motor and remove drained grease.
Replace all plugs. CAUTION: Do Not over-grease.

DISASSEMBLY

DISASSEMBLY

1. Turn off all electrical power.

2. Drain system.

3. Disconnect piping.

4. Remove bolts holding motor to foundation.

5. Remove shaft snap ring (1) within discharge head (2).

6. Use a torch on both ends of casing to break-down
thread sealant at casing threads.

7. Use wrenches on suction housing (21) and discharge
head (2) to unscrew (counter-clockwise) discharge
head and casing. Casing is threaded inside each end
and sealed with thread sealant. The casing may come
off with the discharge head or stay on the suction
housing. If the casing remains on the suction housing
it may be removed with a strap wrench. CAUTION:
Do Not use a pipe wrench on the casing or dam­age will result. The unbroken thread sealant may be
removed by applying heat with a torch.

8. Remove shaft sleeve (4) from shaft.

9. Stages, each consisting of a bowl, impeller, and dif­fuser, can now be removed.

10. Remove motor end-plug to expose slot in end of mo­tor shaft.

11. Heat shaft sleeve/coupling with a torch by directing a
flame through hole in suction housing (21). This will
break down Loctite® thread locking compound to
allow removal of the sleeve/coupling. NOTE: Thread
is right-hand. Turn counter-clockwise to loosen.

12. Remove shaft assembly, including rotating portion
of mechanical seal, by holding motor shaft with a
screw-driver in motor shaft slot while turning pump
shaft assembly counter-clockwise with a ½” wrench.
NOTE: Due to the applied heat, the mechanical seal
must be discarded and replaced with a new mechani­cal seal.

13. Remove bolts holding adapter to motor.

14. Remove suction housing/adapter combination from
motor.

15. Place suction housing/adapter on a flat surface and
push out stationary portion of mechanical seal.

REASSEMBLY

REASSEMBLY

1. Clean all parts, especially pump and motor register
fits, seal seat counter bore in suction housing, and
shaft (in particular where shaft sleeve/coupling fits
against shaft shoulder).

2. Clean shaft sleeve/coupling threads and motor shaft
threads. Clean old Loctite from threads with a wire
brush. Apply Locquic Primer T®, (Loctite® Product
No. 74756 available in Automotive Parts and Hard­ware stores) and allow to dry.

3. Lubricate counterbore of suction housing (21) and
rubber bushing of new stationary seal seat with
light oil or soapy water and press into counterbore
squarely and evenly. CAUTION: Do Not mar or
contaminate the lapped face of the new mechanical
seal seat.

4. With motor in vertical position, remount suction
housing/adapter on motor. Make certain the mo­tor shaft does not dislocate the new mechanical seal
stationary seat.

5. Apply a thin coat of light oil or soapy water to outer
surface of sleeve/coupling and inside diameter of rub­ber portion of the new rotating seal member.

6. Slide spring retainer, spring and rotating member of
the new mechanical seal over the sleeve/coupling,
making certain the seal face stays in the holding
collar, and spring retainer is squarely seated against
shoulder of sleeve/coupling. CAUTION: Take care
to prevent damage or dirt on lapped faces of the new
mechanical seal.

7. Coat motor shaft threads with Loctite® 271.

8. Thread the shaft sleeve/coupling, with rotating por­tion of mechanical seal in place, onto the threaded
motor shaft until the sleeve/coupling bottoms on the
motor shaft shoulder. Use screwdriver in motor shaft
slot to hold while tightening the shaft assembly with
a ½” wrench.

9. Use a straight edge across face of suction housing to
check location of outboard end of shaft sleeve/cou­pling. Due to variations in motor shaft lengths and
pump parts, it will be from 0.080” short (below the
straight edge) to flush.

10. If sleeve/coupling is below the straight edge, add

0.010” shims until top face of shims are one (1) shim
higher than straight edge (interferes with straight
edge).

11. Reassemble stages on shaft, checking impeller hub
height after each stage. Hub must be flush with
straight edge or higher. Add 0.010” shims as neces­sary.

11a. On 10 HP models install bearing spider at half way

point in the stack, use shaft sleeve (13) and shim
accordingly.

12. Install shaft sleeve (4) on shaft.

13. Apply thread sealant (Loctite® HVV Pipe Sealant) to
suction housing (21) threads plus discharge head (2)
threads and reassemble casing to pump. (Tighten to
50 foot pounds torque.) CAUTION: Do Not apply
sealant to casing threads.

14. Turn pump by hand with a ½” socket over the end
of the pump shaft inside the discharge head (2). Turn
counter-clockwise. Unit should turn with resistance
of only the mechanical shaft seal.

14a. Replace snap ring (1) on shaft.

15. Replace motor end plug.

16. Do not start unit until suction line and pump are
completely filled with water. Refer to OPERATION
Section.
