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.
Warranty
LIMITED WARRANTY : Weir Slurry Group, Inc. warrants products of its own manufacture to be free
from defects in material and workmanship under normal use and service for a period of one year after the
date of startup or eighteen months after shipment, whichever comes first. The company's obligation
under this warranty is limited to repairing or replacing the defective parts without charge, F.O.B. its plant,
or, at its sole option, returning the purchase price to the purchaser by crediting the purchaser's account or
otherwise. The company reserves the option of requiring the return of the defective parts (transportation
prepaid) if necessary to establish a claim. The foregoing warranty is the sole and exclusive warranty,
expressed or implied, and there are no warranties which extend beyond the description on the face
hereof including specifically but not limited to warranties of merchantability or fitness for a particular
purpose.
The limited warranty shall not apply to machine work, labor charges or other expenses incurred on
products later found to be defective, or for normal wear and tear, equipment or parts thereof which have
been altered or repaired other than by Weir Slurry Group, Inc. representative, or damaged by improper
installation or application, or subjected to misuse, abuse, neglect or accident.
Weir Slurry Group, Inc. will not approve or accept returns or back charges for labor, materials or other
costs incurred by the Purchaser or others in modification, adjustment, service or repair of equipment
furnished by Weir Slurry Group, Inc. unless such returns or back charges have been previously approved
in writing by an authorized representative of Weir Slurry Group, Inc..
The foregoing warranty applies only to goods manufactured by Weir Slurry Group, Inc. With respect
to goods not manufactured by this company, Weir Slurry Group, Inc.makes no warranty expressed or
implied and any warranties of merchantability or fitness for a particular purpose are expressly excluded
and there are no other warranties which extend beyond the description herein presented.
For more detailed information concerning the limited warranty and any remedy between parties refer
to Terms and Conditions of Sale.
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.

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.
