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 more detailed information concerning the limited warranty and any remedy between parties refer to Terms and Conditions of Sale.


Safety PrecautionsCentrifugal 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. Check motor rotation before installing belts or couplings. Pump must rotate in the direction indicated on the pump and equipment tags.

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 the pump with the discharge line restricted or plugged or against a closed or partially closed discharge valve.

7. Do not start a pump which is “windmilling” in reverse direction due to back flow through the pump.

8. Do not insert fingers, hands, arms, legs or any other objects into the rotating components of the pump or motor. Loose clothing should not be worn when working with rotating equipment.

9. Wear parts should be inspected regularly to prevent damage to other components and to avoid personal injury. Insure that all wear parts are in good working order. Worn parts should be replaced with new O.E.M. 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 the rotating element does not turn freely.

14. Check all fasteners to insure they are the proper material, properly sized and tightened to the torque ratings of the fasteners and/or specifications.

15. Do not apply heat to the impeller to assist in removing it from the shaft.


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 RecommendationsInspection 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.


Coupling Alignment

When a direct-connected motor is used, alignment between the motor and the pump must be maintained for extended life and reliable service. After checking the motor direction of rotation, install and align the coupling using the following procedure.

Check parallel and angular misalignment by measuring the dimensions shown on the sketch, Figure 1. Table 2 shows maximum allowable limits for the Woods type couplings. For other types of couplings, follow the manufacturer's recommendations.

TABLE 2

Lower Screen Suction Extensions

When replacing or adding a lower screen suction extension, the connection between the pump casing and the flange on the suction extension MUST BE AIR TIGHT. Always apply a coat of Silastic 732 RTV sealant on mating surfaces of acid-proof and abrasion-resistant models. Use the gasket provided on hard iron or alloy pumps. Tighten nuts and bolts evenly. See Figure 2.


Controls

All Galigher Vertical Pumps can be controlled by a manual motor starting switch or by automatic liquid level controls with either a float, probe, or mercury switch. Probe type level controls are recommended for pumps longer than 6 feet.

Minimum submergence required for Galigher Vertical Pumps to start pumping liquid is 3” above the upper screen. These pumps will continue pumping until liquid is pumped down to the lower screen, although the capacity will be slightly reduced when the liquid level is below the upper screen.

Probe Type Level Control

A probe type level control shown in Figure 3 consists of probes, probe housing and control box and is assembled in the following manner.

1. Screw the probe housing into the threaded opening provided on the mounting plate. After installing the probe housing, screw the probes in the bottom of the housing. Two probes are used for hard iron and abrasion-resistant pumps and three probes for acid-proof pumps for off/on control only. Additional probes may be used for other functions.

2. Cut one probe to desired depth where the pump is to start operating and one probe to the depth where the pump is to shut off. (Note: The third probe on acid-proof pumps is the electrical ground.)

3. Install the necessary wiring from the probe housing to the motor control box. The control box is usually mounted remotely from the pump.

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 RecommendationsPre-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.


MotorIt is recommended that the motor be well ventilated when in operation. Please refer to the motor manufacturer for recommended service instructions.

Ordering PartsSeveral 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.
