DANGER
RISK ASSESSMENT
A comprehensive risk assessment of the installation site, pump equipment, and pumping
system must be completed prior to receiving the equipment. The risk assessment should
include but is not limited to the following: lifting procedures, pump equipment, system
piping, system valving, system operation and readiness, containment of pressurized fluid,
intake structures, electrical systems, hazardous materials and conditions, lock-out-tag-out
procedures, start-up and shutdown procedures, potential for reverse flow and/or reverse
pump rotation, water hammer, safety considerations for all personnel and public, and site
security including preventing access to the pump intake structure.
DANGER
PUMP SIGNAGE AND ACCESS
Do not allow anyone near the suction or open discharge of the pump during operation.
Pumps can create strong forces that will pin individuals. It is highly recommended to post
signage and restrict access to the pump suction and/or intake structure to prevent serious
injury or death.
DANGER
LOCKOUT-TAGOUT (LOTO)
• Prior to allowing any checking, maintenance, or other work on the equipment, all
hazardous energy sources (for example, electrical, mechanical, hydraulic, pneumatic,
etc.) must be isolated using an appropriate lockout-tagout procedure.
•Ensure that the intake and discharge openings are totally isolated from all potentially
pressurized connections and that they are, and can only be exposed to atmospheric
pressure.
• Drain the pump and isolate pipework before dismantling the pump. The appropriate
safety precautions must be taken when the pumped liquids are hazardous.
• Failure to follow appropriate LOTO procedures may result in serious personal injury or
death.
DANGER
GUARDS
Contact with rotating equipment can result in serious injury. Appropriate guards must be
installed at all times during operation. Any procedures requiring the removal of the
equipment guards must be performed by qualified personnel trained to perform such work.
DANGER
PERSONNEL INJURY FROM FALLS
Working at height may be required when working on equipment (for example, when
adjusting the impellers with a hollow shaft driver). Always wear appropriate PPE, such as a
safety harness and restraint system, when working at heights.

DANGER
VAPORIZATION
• Do not operate the pump at low or zero flow conditions, or under any circumstances that
causes the pumped liquid to vaporize.
• Personnel injury and equipment damage could result from the high temperature and
pressures created if the pumping liquid vaporizes.
•Low or zero flow conditions must be avoided under any circumstances for any significant
period of time (more than 1 minute) due to the risk of heat/vaporisation of pumped fluid in
the casing that may cause subsequent explosion.
DANGER
THERMAL SHOCK
Do not feed very hot liquid into a cold pump or very cold liquid into a hot pump. Thermal
shock may cause damage to the internal components and rupture the pump casing.
DANGER
LIFTING DEVICE SAFETY
• Lifting devices of adequate capacity must be used whenever they are required.
• Safe workshop practices must be applied during all assembly and maintenance work.
• Personnel must never work under suspended loads.
DANGER
DANGER
Unapproved parts, unapproved pump construction, and misapplication (for example, foot
valves, non-OEM parts, worn/damaged/corroded/obsolete parts, mis-assembly, excess
pressure, unapproved fluids, etc.) may result in serious personal injury or death. Only use
supplied equipment for its intended purpose.
WARNING
SHARP EDGES
• Before handling, identify work parts that could be hazardous due to sharp edges. All
metal components must be considered to have sharp edges.
• Pump components can have sharp or jagged edges. Handle parts carefully, to prevent
damage to slings or personal injury.

3 General Information and Description
3.1 General Information
Floway Pump's standard practice is to ship close coupled pumps assembled. Where long pump lengths,
shipping limitations, handling limitations and headroom limitations prevent complete assembly, we will ship
the pump sub-assembled. It is the responsibility of the installer to ask for assistance should it be required to
properly assemble and install the pump.
The duration of satisfactory service obtained from the equipment, in part, depends on proper installation and
maintenance.
This instruction manual provides basic guidelines for installation, operations and maintenance of the
equipment and other safety precautions required for personnel. Due to the many variations and custom
designed units it is impossible to cover every design variation or contingency which may arise. However, the
basic information contained herein will answer most questions.
3.2 Identification
• Should questions arise concerning the pump equipment, the complete pump serial number will be
required for identification. The pump serial number is stamped on metal nameplates affixed to the
discharge head and bowl assemblies.
•The driver has a separate nameplate attached to it.
•When requesting information on the driver, both the driver serial number and pump serial number must
be provided.
3.3 General Description
The major components of vertical turbine pumps include:
• Driver
• Discharge Head Assembly
• Column Assembly (when used)
• Bowl Assembly (with strainer as applicable)
• Suction Vessel (when used)

3.3.1 Drivers
A variety of drivers can be used; however, electric motors are most common. In this manual, electric motor
drivers are grouped into two categories:
1. Hollow Shaft Drivers: where the pump shaft extends through a tube in the center of the motor shaft and
is connected to the driver by a clutch assembly at the top of the driver.
2. Solid Shaft Drivers: where the motor shaft is solid and projects below the driver mounting base. This
type of driver requires an adjustable coupling to connect to the pump.
3.3.2 Discharge Head Assembly
• The discharge head supports the driver, column, and bowl assemblies in addition to providing a
discharge connection (the type VU discharge connection is located on one of the column pipe sections
below the discharge head).
•A shaft sealing arrangement is located in the discharge head to seal the rotating shaft where it passes
from the stationary housing (liquid chamber). Typically, the shaft seal is either a mechanical seal
assembly or a packing box.
3.3.3 Column Assemblies
Column assemblies are of two basic types, either of which can be used on vertical turbine pumps:
1. Open Lineshaft Construction: utilizes the liquid being pumped to lubricate the lineshaft bearings.
2. Enclosed Lineshaft Construction: has an enclosing tube around the lineshaft and utilizes oil, grease or
injected liquid (usually clean water) to lubricate the lineshaft bearings (not used on barrel pumps).
Column assemblies consist of the following:
• Column Pipe: which connects the bowl assembly to the discharge head and carries the pumped liquid
to the discharge head. Column pipe is either threaded or flanged.
•Shaft: which connects the bowl shaft to the driver; and may contain bearings if required for the
particular unit.
• Enclosing Tube (if applicable): surrounds the lineshaft to contain the supplied lubrication.
3.3.4 Bowl Assemblies
The bowl assembly consists of the following:
• Impellers rigidly mounted on the bowl shaft which rotate and impart energy to the fluid.
•Bowls to contain the increased pressure and direct the fluid.
• Suction bell or case which directs the fluid into the first stage impeller.
• Bearings located in the suction bell (or case) and each bowl.
A separate instruction manual is available which provides construction details and repair instructions for
Floway bowl assemblies.
3.3.5 Suction Vessel
The suction vessel may consist of a barrel with or without suction fitting, to connect to customers piping
arrangement, or a storage tank with suitable opening to mount the pump.
Whatever the arrangement may be, it must provide:
• Adequate support for the unit
•A means of supplying the pump with liquid
NOTICE
Some units do not require a column assembly, as the bowl assembly is connected directly
to the discharge head.

4.4.1 Lifting Pump Components and Pump Assemblies
Refer to the certified outline drawing for approximate pump assembly weights.
Pump components and assemblies must only be lifted from the appropriate locations. If there is any doubt
regarding proper lifting methods and locations, contact your nearest manufacturer’s representative.
• Cans/Barrels must be lifted using appropriate lifting devices attached to the mounting plate.
• Discharge heads are fitted with lifting lugs suitable to support the entire weight of the pump. Typically
two or more lifting lugs are supplied, a minimum two point lifting method is required (refer to Figure 4-2
on page 16 for fabricated heads and Figure 4-3 on page 16 for cast heads).
• Column and bowl assemblies must be lifted using an appropriate clamping fixture. The fixture must
positively lock to the item being lifted and have adequate strength to support the assembly’s weight. A
common fixture design employs beams and threaded rods that can be fastened around the assembly
(refer to Figure 4-4 on page 16). When clamping to threaded column, the upper column coupling must
be fully installed to provide a stop for the lifting clamp placed below the coupling. If the column is
supplied with optional lifting lugs, those may be used to lift the assembly.
Lift devices (straps, chains, etc.) attached to the pump must not exceed a 45 degree angle to the vertical
position. Exceeding this angle could overload the lifting location (refer to Figure 4-2 on page 16).
When lifting an assembled pump, it must be supported at minimally two locations. When lifting to the vertical
position, use the discharge head lifting lug locations to lift the pump assembly (refer to Figure 4-1 on page
15). For pump units over 40 ft in length, the pump shall be assembled during installation vertically in place
over the mounting location.
If the unit is supplied with a separate motor stand (that is, a component bolted between the driver and
discharge head), do not lift the entire pump unit from the motor stand. The motor stand lifting lugs are for
lifting the motor stand assembly only.
WARNING
LIFTING DRIVERS AND AUXILIARY EQUIPMENT
Refer to the manufacturer’s instruction manual for proper lifting techniques of all drivers
and auxiliary equipment. Driver lifting locations must only be used to lift the driver. Do not
use the driver lifting locations to lift the assembled pump and driver.
WARNING
PERSONAL INJURY AND EQUIPMENT DAMAGE
Never lift any assemble by the bowl shaft or lineshaft. This can result in damage to the
shaft and personal injury.
WARNING
PERSONNEL INJURY
• Clamping fixtures that do not positively lock to the assembly being lifted may come loose
and cause personal injury. Always ensure the clamping fixture is of an appropriate design
to support the load and has secure means to lock onto the assembly being lifted.
• Do not lift bowl assemblies by placing lifting devices through the flange bolt holes, the
cast bowl flange holes may break through and result in dropping the load and personal
injury.
