IntroductionGaligher Vertical Pumps are rugged, cantilevered, centrifugal slurry pumps that can handle fluids with

abrasive solids, pulps, acids, chemical slurries, and froths with ease. These pumps can be furnished with

abrasion resistant ELASTOGUARD® covered parts for long life, acid-proof parts for corrosion protection,

or with metal construction for higher pressure and higher temperature service. Materials of construction

can be mixed to provide unique arrangements of elastomer and metal for special application

requirements.

The double-suction design and construction provides a thrustless impeller that will not air lock. A

rugged heavy duty bearing assembly supports the shaft and bearings and is designed to provide

dependable operation and long life.

A three point mounting and adjustment feature allows easy setting of impeller clearances while

maintaining pump shaft and case alignment.

The discharge pipe terminates above the heavy-duty mounting plate to provide easy access for

connections to external piping.

The Galigher Vertical Pumps can be furnished with special features and arrangements. Suction pipe

extensions are available to allow moderate increase in sump depth operation. By adding proven

submerged intermediate stabilizer bearings, operation at depths up to 25 feet is possible. Liquid level

sensors and controls are available which will allow automatic operation. Weir Slurry Group, Inc. stands

ready to assist in solving performance, operational, or maintenance problems that may be experienced.

For assistance call (608) 221-2261.

Safety Precautions

Centrifugal pumps can be dangerous if used improperly. Disregarding any of the

following precautions may result in a pump which does not function properly and which

could cause damage or injury. Operation and maintenance instructions must be read before

starting the pump.

The following list is not comprehensive, but is provided as examples of actions that can

damage a pump and cause injury.

1. Do not connect the pump to the drive system before first checking to see that the drive

motor rotation is correct. Rotation must be clockwise when viewed from the drive end of

the pump.

2. Do not work on a pump unless the drive system is locked out and the pump is disconnected

from the drive system.

3. Do not operate a pump when the bearing temperature measured on the outside of the

housing exceeds 220° F.

4. Do not continue to operate a pump when there are indications of internal rubbing, binding or

knocking.

5. Do not operate a pump with the belt or coupling guard removed.

6. Do not operate a pump with the discharge line restricted or plugged or the discharge

valve closed.

7. Do not start a pump which is "windmilling" in the reverse direction because fluid is flowing

back down the discharge pipe and into the pump.

8. Do not stick hands, arms, legs or any other objects into the rotating components of the

pump or motor.

9. Do not use worn or faulty parts.

10. Do not weld attachments to the pump.

11. When the top screen of the vertical pump is exposed while pumping, it is normal for

splashing of the sump fluid to occur. Proper splash protection should be provided.

12. Lubrication water, when required, must be turned on before starting the pump.

13. Do not operate the pump if solids have settled in the casing and rotating elements cannot be

turned by hand.

For maximum safety and reliability, use only genuine Galigher pump replacement parts.

Only Galigher pump parts meet all original manufacturing specifications. ELASTOGARD

proprietary rubber compounds insure maximum abrasion and corrosion resistance.

The use of non-Galigher pump parts in the Company's products is not authorized, and may

result in voiding the Company's factory warranty and in providing factory service support.

Further, the Company disclaims product liability for any product in which non-Galigher pump

parts are used.

General Installation Recommendations

Inspection Upon Arrival

Your pump has been carefully inspected prior to shipment to insure that it meets your

requirements. Please inspect the pump upon arrival for any damage, which may have occurred

during shipment. Report any damage immediately to the carrier. Leave all shippping covers

and shaft blocking attached until ready for installation.

Spare parts should be inspected with equal care for shipping damage. Storage locations for

rubber components should be made in cool shaded areas away from electrical equipment to

extend shelf life as long as possible.

Pump Location

Select the pump location so that the unit is accessible for inspection during operation and

during maintenance operations involving removal and disassembly.

Piping

A check valve and a gate valve are often installed in the discharge line. The check valve is

used to prevent fluid from flowing back through the pump while it is shut down. The gate valve

blocks the discharge line during maintenance.

When rigid discharge piping is used, caution should be exercised so that external stresses

are not applied to the pump discharge flange from mis-alignment, lack of support, or vibration.

It is recommended that an expansion joint and independent pipe support be used so that the

pump will not have to support the weight of the discharge piping.

It is recommended that provisions be made to supply clear water to allow flushing out the

casing and piping after pumping settling type solids.

Mounting Instructions

Heavy-duty mounting plates are furnished on all Galigher Vertical Pumps. These pumps

may be mounted on tanks, sumps, barges, or floats (with motor properly electrically grounded).

The pump should be firmly mounted on a level mounting plate or crossbeams and should not

rest on the pump casing or screen. Minimum recommended sump dimensions for proper

operation are shown below in Table 1 on next page.

TABLE 1

V-Belt Tension

V-belts are not installed at the factory when the pump is shipped. Motor direction of rotation

must be checked before the V-belts are put on the sheaves. Use a straight edge to align

sheaves horizontally. V-belts should then be adjusted so that the belts have from ½” to ¾” play

when depressed midway between sheaves. Excessive belt tension will cause unnecessary load

on the bearings and excessive belt wear.

Float Type Level Control

To assemble the float type level control, follow the procedure listed below referring to the

drawings shipped with the pump and Figure 4. DO NOT USE A FLOAT TYPE LEVEL

CONTROL ON PUMPS LONGER THAN 84”.

1. Secure the switch bracket (1) float switch (7) and float rod guide (3), if provided, to the pump

mounting plate.

2. Screw the float rod (6) into the float ball (2).

3. If the ball and rod are rubber covered (acid-proof), apply Silastic 732 RTV sealant to the joint

between the ball and rod to insure an acid-proof seal.

4. Slip the float rod up through the rod hole in the mounting plate or guide and put the lower set

collar (5) over the top of the rod (6). Push the rod through the clamp on the float switch arm

and slip the upper collar (5) over the rod.

5. Adjust the ball to the position desired for the pump to shut-off, and set the upper collar

securely just above the float switch arm.

6. Raise the ball to the position desired for the pump to start-up and set the lower collar

securely just below the float switch arm. Be sure the float switch is tripped "off" by the upper

rod collar before the lower rod collar hits the mounting plate.

7. Install the necessary wiring from the float switch to the motor controls in accordance with the

Float Switch Assembly Drawing furnished with the pump.

Operating And Servicing Recommendations

Pre-Starting Recommendations

1. Visually check all main and auxiliary piping to insure that all connections have been properly

made.

2. Check voltage, fuse size, starter, heater amperage ratings and frequency of the electrical

supply against the motor nameplate.

3. Visually inspect all the electrical connections to the motor and the control circuit.

4. Check to be sure that the wood blocking has been removed between the pump shaft and

the support tubes and that the upper screen is secured to the coverplate.

5. With the motor disconnected from the pump assembly, check the motor direction of rotation

by momentarily starting the motor. Direction of rotation must be as shown on the name-tag

on the pump (clockwise looking toward the impeller from the motor end of the shaft).

CAUTION: STARTING AND RUNNING THE PUMP BACKWARD WILL CAUSE DAMAGE TO

INTERNAL PARTS.

6. All pumps have been properly greased before shipping. For initial start up and subsequent

servicing, we recommend using a superior general purpose grease with good high

temperature characteristics such as TEXACO REGAL AFB-2, CHEVRON EP-2 or equal for

the pump bearings, seals and motors.

Start Up Recommendations

1. Visual inspection should be made of the pump and its installation before starting. Check

that all mounting supports, external nuts, bolts and fittings are secure, and that the

discharge piping is tight and secure.

2. It is normal to have the discharge valve 90% closed when the pump is started since much

less horsepower is required under these conditions.

DO NOT OPERATE THE PUMP IN A RESTRICTED FLOW CONDITION FOR LONGER THAN

NECESSARY.

3. All flow, pressure and temperature gauges should be monitored to insure that the pump is

operating within specified limits. If the bearing column temperatures are monitored, they

should not exceed 220° F.

General Operating Instructions

1. The unit should always be started under the lowest possible load. This is usually

accomplished by starting with the discharge valve 90% closed. This is especially important

when two pumps are operated in parallel or when switching to a standby unit.

2. Automatic level controls should be set to start the unit when the liquid is at least 3 inches

above the upper inlet screen.

3. Do not start operating the pump while it is "windmilling" backwards from fluid running back

through the pump case from the discharge line.

4. Flush out the pump with clear fluid whenever possible prior to shut down to reduce solids

settling problems that could load up the impeller on startup.

5. Completely drain the pump lines and sump, if the possibility exists of freezing while not

operating.

6. The pump must never be submerged above the mounting plate as serious damage to both

the motor and bearing assembly could result. If submerged, the pump bearing assembly

should be disassembled, cleaned, the bearings repacked with fresh grease, and the motor

checked out before further operation.

Motor

It is recommended that the motor be well ventilated when in operation. Please refer to the

motor manufacturer for recommended service instructions.

Ordering Parts

Several copies of the Installation, Operation and Maintenance Manual are provided with

each pump. A general assembly drawing and bearing column assembly drawing with detailed

descriptions of all of the pump components are provided with every pump shipped and should

be used in conjunction with this manual. These drawings should always be referred to when

ordering replacement parts. Recommended spare parts are identified on these drawings.

Orders for spare parts should specify quantity ordered, part number, item description, and

type of material (i.e. rubber type, cast iron or alloy, etc.). If the general assembly drawing

supplied with the pump is not available, refer to the pump serial number and use the item

numbers on the General Assembly Drawing at the end of the Specific Maintenance Manual

when ordering parts.
