1 Introduction and Safety
1.1 Important Safety Notice
To: Our Valued Customers:
User safety is a major focus in the design of our products. Following the precautions outlined in this man-
ual will minimize your risk of injury.
ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and operat-
ed.
Safe installation, operation, and maintenance of ITT Goulds Pumps equipment are an essential end user
responsibility. This Pump Safety Manual identifies specific safety risks that must be considered at all
times during product life. Understanding and adhering to these safety warnings is mandatory to ensure
personnel, property, and/or the environment will not be harmed. Adherence to these warnings alone,
however, is not sufficient — it is anticipated that the end user will also comply with industry and corporate
safety standards. Identifying and eliminating unsafe installation, operating and maintenance practices is
the responsibility of all individuals involved in the installation, operation, and maintenance of industrial
equipment.
Please take the time to review and understand the safe installation, operation, and maintenance guide-
lines outlined in this Pump Safety Manual and the Instruction, Operation, and Maintenance (IOM) man-
ual. Current manuals are available at https://www.gouldspumps.com/en-US/Tools-and-Resources/Litera-
ture/ or by contacting your nearest Goulds Pumps sales representative.

1.2 Safety Warnings
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety
precautions.
WARNING:
A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel
can explode, rupture, or discharge its contents if sufficiently over pressurized causing death,
personal injury, property damage, and/or damage to the environment. All necessary measures
must be taken to ensure over pressurization does not occur.
WARNING:
Operation of any pumping system with a blocked suction and discharge must be avoided in all
cases. Operation, even for a brief period under these conditions, can cause superheating of
enclosed pumpage and result in a violent explosion. All necessary measures must be taken by
the end user to ensure this condition is avoided.
WARNING:
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the con-
tents of the pump and eliminate the possibility of exposure, particularly if hazardous and/or tox-
ic. Potential hazards include, but are not limited to, high temperature, flammable, acidic, caus-
tic, explosive, and other risks.

WARNING Receiving:
Assembled pumping units and their components are heavy. Failure to properly
lift and support equipment can result in serious physical injury and/or equip-
ment damage. Lift equipment only at specifically identified lifting points or as
instructed in the current IOM. Current manuals are available at www.gould-
spumps.com/literature_ioms.html or from your local ITT Goulds Pumps sales
representative. Note: Lifting devices (eyebolts, slings, spreaders, etc.) must
be rated, selected, and used for the entire load being lifted.
WARNING Alignment:
Shaft alignment procedures must be followed to prevent catastrophic failure of
drive components or unintended contact of rotating parts. Follow coupling
manufacturer's coupling installation and operation procedures.
WARNING Before beginning any alignment procedure, make sure driver power is locked
out. Failure to lock out driver power will result in serious physical injury.
CAUTION Piping:
Never draw piping into place by forcing at the flanged connections of the
pump. This may impose dangerous strains on the unit and cause misalign-
ment between pump and driver. Pipe strain will adversely effect the operation
of the pump resulting in physical injury and damage to the equipment.
WARNING Flanged Connections:
Use only fasteners of the proper size and material.
WARNING Replace all corroded fasteners.
WARNING Ensure all fasteners are properly tightened and there are no missing fasten-
ers.

When installing in a potentially explosive environment, please ensure that the
motor is properly certified.
WARNING Operating pump in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
WARNING Lock out driver power to prevent accidental start-up and physical injury.
WARNING The impeller clearance setting procedure must be followed. Improperly setting
the clearance or not following any of the proper procedures can result in
sparks, unexpected heat generation and equipment damage.
WARNING If using a cartridge mechanical seal, the centering clips must be installed and
set screws loosened prior to setting impeller clearance. Failure to do so could
result in sparks, heat generation, and mechanical seal damage.
WARNING Never operate a pump without coupling guard properly installed. Personal in-
jury will occur if pump is run without coupling guard.
WARNING Make sure to properly lubricate the bearings. Failure to do so may result in ex-
cess heat generation, sparks, and / or premature failure.
CAUTION Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical seal dry, even for a few seconds, can cause seal damage and
must be avoided. Physical injury can occur if mechanical seal fails.
WARNING Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.
WARNING DO NOT operate pump below minimum rated flows or with suction and/or dis-
charge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical in-
jury.
WARNING Ensure pump is isolated from system and pressure is relieved before disas-
sembling pump, removing plugs, opening vent or drain valves, or disconnect-
ing piping.
WARNING Shutdown, Disassembly, and Reassembly:
Pump components can be heavy. Proper methods of lifting must be employed
to avoid physical injury and/or equipment damage. Steel toed shoes must be
worn at all times.
WARNING The pump may handle hazardous and/or toxic fluids. Observe proper decon-
tamination procedures. Proper personal protective equipment should be worn.
Precautions must be taken to prevent physical injury. Pumpage must be han-
dled and disposed of in conformance with applicable environmental regula-
tions.
WARNING Operator must be aware of pumpage and safety precautions to prevent physi-
cal injury.
WARNING Lock out driver power to prevent accidental startup and physical injury.
CAUTION Allow all system and pump components to cool before handling them to pre-
vent physical injury.
CAUTION If pump is a Model NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150,
4550, or 3107, there may be a risk of static electric discharge from plastic
parts that are not properly grounded. If pumped fluid is non-conductive, pump
should be drained and flushed with a conductive fluid under conditions that
will not allow for a spark to be released to the atmosphere.
WARNING Never apply heat to remove an impeller. The use of heat may cause an explo-
sion due to trapped fluid, resulting in severe physical injury and property dam-
age.
1.4 General precautions
VMP Installation, Operation and Maintenance Instructions 7

CAUTION Wear heavy work gloves when handling impellers as sharp edges may cause
physical injury.

can cause physical injury.
WARNING Noise:
Sound pressure levels may exceed 80 dbA in operating process plants. Clear
visual warnings or other indicators should be available to those entering an
area with unsafe noise levels. Personnel should wear appropriate hearing pro-
tection when working on or around any equipment, including pumps. Consider
limiting personnel’s exposure time to noise or, where possible, enclosing
equipment to reduce noise. Local law may provide specific guidance regard-
ing exposure of personnel to noise and when noise exposure reduction is re-
quired.
WARNING Temperature:
Equipment and piping surfaces may exceed 130ºF (54ºC) in operating proc-
ess plants. Clear visual warnings or other indicators should alert personnel to
surfaces that may reach a potentially unsafe temperature. Do not touch hot
surfaces. Allow pumps operating at a high temperature to cool sufficiently be-
fore performing maintenance. If touching a hot surface cannot be avoided,

3 Storage
3.1 Storage
Goulds Pumps carefully preserves and protects its products for shipment. However, the effective life of
the preservatives applied at the factory can vary 3 to 8 months depending on the severity of the environ-
ment in which the equipment is stored. This section provides procedures for preparation prior to storage
and maintenance during storage of Goulds pumps. These procedures are necessary to protect the preci-
sion parts of the pumps. Specific procedures for storing motors, gearheads, and engines, should be ob-
tained from the equipment manufacturer. This section is intended be of general assistance to users of
Goulds pumps. It shall not modify, amend and/or otherwise alter the scope of Goulds Pumps warranty
responsibilities to the purchaser in any way whatsoever.
3.2 Storage preparation
Goulds vertical pumps require proper preparation for storage and regular maintenance during storage.
The pump shall be considered in storage when it has been delivered to the job site and is waiting for
installation.
3.3 Recommended storage procedures
1. Controlled storage facilities should be maintained at an even temperature 10ºF or more above
the dew point with relative humidity less than 50% and little or no dust. If these requirements can-
not be met the pump is to be considered in uncontrolled storage.
2. For uncontrolled storage periods of 6 months or less, the pump is to be inspected periodically lo
ensure that all preservatives are intact.
3. All pipe threads and flanged pipe covers are to be sealed with tape.
4. The pump must not be stored closer than 6 inches from the ground.
3.4 Preparations for uncontrolled long term storage
When applicable to the pump, storage periods over 6 months require the preceding uncontrolled storage
procedure plus the following:
1. Inspect the lube oil and seal flush piping, and either fill the piping with rust preventative oil, or re-
coat the piping periodically to prevent corrosion.
2. Place 10 pounds of moisture absorbing desiccant or 5 pounds of vapor phase inhibitor crystals near
the center of the pump. If the pump is as assembled, place an additional one pound in the dis-
charge nozzle securely fastened to the discharge elbow.
3. Install a moisture indicator near the perimeter of the pump. Cover the pump with 6 mil minimum
thickness black polyethylene or equal and seal it with tape. Provide a small ventilation hole approxi-
mately 1/2 inch diameter.
4. Provide a roof or a shed shelter to protect from direct exposure to the elements.

4 General Description
4.1 General description
The Model VMP Autoprime pump is an automatic self priming unit designed for efficient unloading and
stripping of product tankers and tank barges, also for ballast, bilge, and fuel oil transfer services. A
unique feature of the Autoprime pump is its ability to discharge air or vapors quickly and automatically for
fast and complete stripping.
4.2 Drivers
Drivers are supplied in a variety of types and sizes to meet a wide range of operating requirements. Most
common are right angle drive units with solid or hollow shafts coupled to internal
combustion engines, or steam turbines. In addition, electric motors with solid or hollow shafts are provid-
ed. Occasionally a right angle gear drive coupled to a horizontal electric motor is provided to drive the
pump.
4.3 Discharge head
The discharge head may be a low or high profile head depending on construction requirements. A
Goulds exclusive primacy-clamatic feature may be provided to supply automatic temporary lubrication by
the product being handled to the mechanical seal, or stuffing box bushing during the priming or stripping
cycle. The discharge head features an automatic venting system which incorporates a vent line from the
barrel, or tank to pump discharge, and a check valve that prevents recirculation from pump discharge
when pump is in operation. The discharge head also features a bearing in its base to ensure stability of
shaft in the stuffing box area.
4.4 Column
The column is fabricated in sections five feet or less to provide vibration free operation below shaft first
critical speed. Flanged construction provides positive shaft and bearing alignment. Pumps over 15 feet
long are normally equipped with spring loaded sway braces to protect the column from the effects of hori-
zontal movements and twists of the vessel, particularly in a seaway. The lineshalt is supported within the
column by use of bearing retainers secured to the column assembly.
4.5 Autoprime valve
An autoprime valve is located near the base of the bottom column. Some larger pumps may have as
many as four autoprime valves located at 90 degree intervals around the column. When the
pump is not in operation, spring pressure keeps the valve open. On pump startup, discharge pressure
closes the valve. When pump loses prime, loss of pressure allows the valve to open. Liquid in column
above the valve then flows into barrel and pump suction, repriming pump. Vapor displaced in the barrel is
vented to discharge and evacuated from the system through main discharge.
4.6 Bowl assemblies
The bowl assembly is designed to operate when the liquid in the barrel or tank is sufficient to submerge
the priming stage. The priming stage normally consists of a mixed flow impeller, suction bell and shaft
with the ability to handle air, vapor, and at the same time create vacuum. The stages following the pri-
ming stage consist of high efficiency turbine bowls which contribute the largest proportion of head during
normal pumping operation.

5 Installing the Pump
5.1 Pump installation
Pumps under 6,000 lbs. and 20 feet or less in length are usually shipped completely assembled with the
exception of the driver, mechanical seal, and in some cases, the driveshaft when a vertical hollow shaft
driver is furnished. When provided, see the Certified Pump Outline Drawing for the applicable bowl con-
figuration.
5.2 Horizontal pump installation
There are two methods of assembling and installing the VMP pump, vertical, and horizon. The vertical
method is described in the following pages, but the pump components can be assembled horizontally by
following the procedural steps described for the vertical method. The sequence and procedural steps of
assembling the pump components are exactly the same, and can be applied either vertical or horizontal
for all practical purposes. Observe the following:
1. Support the headshaft, pumpshaft or, lineshaft as applicable, horizontally during assembly at sever-
al points to prevent bending or damaging the shafts, Refer to 5.3 Installing a completely assembled
pump on page 14, Step 1.
2. Assemble pump components horizontally on blocks. After pump is completely assembled less driver
proceed with Step 3, 5.3 Installing a completely assembled pump on page 14, Step 3.
5.3 Installing a completely assembled pump
When a pump is shipped completely assembled (with the exception of the driver) proceed as follows:
1. When a driveshaft or headshaft is shipped separately, check shaft for straightness, average total
runout shall not exceed 0.010 T.I.R. for every 10 feet. Shalt must be within tolerance prior to instal-
lation.
2. Remove stuffing box and carefully slide shalt through bearing retainer and thread into coupling. Use
extreme care not to damage retainer bearing.
3. Install gasket on the barrel opening.
4. Using two cranes the pump may be lifted into position by slinging through the windows (hand holes)
on discharge head and around the bowl assembly. Hoist pump horizontally, guiding the
lower end to prevent dragging on the floor.
5. Lower the bowl assembly and position over the barrel opening.

14 VMP Installation, Operation and Maintenance Instructions

Figure 1: Pump installation
6. Lower pump assembly into the barrel until sway braces engage inside of the barrel. The sway bra-
ces are under spring tension and fit snugly in the barrel. Continue to lower the assembly until the
discharge head flange engages the barrel flange. Install capscrews and secure discharge head to
barrel. Tighten capscrews in diametrically opposite pairs. Install stuffing box, refer to Stuffing Box
Installation.
7. Refer to Installing the Driver (VHS) for the installation of hollow shaft gearhead and electric motor
driven pumps and also for the adjustment of open and enclosed impellers. Installing the Driver
(VSS) covers the installation of solid shaft gearhead and electric motor driven pumps and also the
adjustment of open and enclosed impellers. Pump Startup and Operation, covers startup.

6 Installing the Bowl Assembly
16 VMP Installation, Operation and Maintenance Instructions

Prior to installing the bowl assembly, remove all accumulated dust, oil, or other foreign matter from exter-
nal surfaces of the bowl assembly and proceed as follows:
1. Position a suitable lifting device over the barrel opening. Place two timbers or I-beams across the
barrel opening strong enough to safely support the weight of the entire pump assembly.
2. Place an elevator clamp just below the top bowl flange or thread eye-bolts through bolt holes in the
flange, and hoist into position over the barrel.
Figure 3: Bowl assembly installation
3. Lower bowl assembly until flanges of elevator clamp, or bowl flange rests firmly on the barrel or
supports.
4. Place a cover over bowl assembly to prevent entrance of dirt or other foreign matter.
5. Threaded shaft coupling: When
threaded coupling is not installed on the pump shaft, proceed as follows:
a) Install threaded coupling onto pumpshaft screwing it on for one-half its length.
b) A line wire inserted in the drilled hole at the center of the coupling can be used as a gage to
determine when the coupling is correctly positioned on the pumpshaft. Remove the wire after
installing the coupling.
NOTICE:
Shaft threads are left hand.
6. Keyed shaft coupling: When a pump is equipped with keyed shafts assemble as follows:
a) Install retainer (650) and insert key (730D) onto shaft.
