area would cause the risk of an explosion.

commission the manufacturer/supplier to provide
applicable training.

Always coordinate repair activity with operations and
health and safety personnel. Follow all plant safety
requirements and applicable safety and health laws
and regulations.

1.6.3 Safety action

This is a summary of conditions and actions to help
prevent injury to personnel and damage to the
environment and to equipment. For products used
in potentially explosive atmospheres section 1.6.4
also applies.

U-MAG™ pumps contain extremely strong
permanent neodymium magnets which could affect the
functioning of pacemakers and implanted heart
defibrillators. If you wear these devices keep sufficient
distance to magnets.

Magnets produce a far-reaching, strong
magnetic field. They can damage laptops, computer
hard drives, credit and ATM cards, data storage media,
mechanical watches, hearing aids and speakers. Keep
magnets away from devices and objects that could be
damaged by strong magnetic fields.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

GUARDS MUST NOT BE REMOVED WHILE

THE PUMP IS OPERATIONAL

This symbol is used in safety instructions to
remind not to rub non-metallic surfaces with a dry
cloth; ensure the cloth is damp. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.

This sign is not a safety symbol but indicates

an important instruction in the assembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the personnel
in question do not already possess the necessary
knowledge and skill, appropriate training and instruction
must be provided. If required, the operator may

Page 5 of 40

DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.

NEVER use heat (risk of explosion) to

disassemble any portion of the pump.

HIGH TEMPERATURES may be present.
Pump surface temperature is directly related to the
temperature of the working fluid. Never operate pump
above the rated temperature of 121°C (250°F).

U-MAG ENGLISH 26999990 10-14

HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment
is required when handling these components. To lift
heavy pieces above 25 kg (55 lb.) use a crane
appropriate for the mass and in accordance with
current local regulations.

Personal Protection Equipment suitable for
the conditions and environment must be worn at all
times.

THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result
in damage or breakage of components and should be
avoided.

HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
supplies can present a danger to operators and
persons entering the immediate area action must be
taken to avoid accidental contact. If complete
protection is not possible, the machine access must
be limited to maintenance staff only, with clear visual
warnings and indicators to those entering the
immediate area.

If the temperature is greater than 80 ºC (175 ºF) or
below -5 ºC (23 ºF) in a restricted zone, or exceeds
local regulations, action as above shall be taken.

HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate siting of the pump, limiting personnel
access and by operator training. If the liquid is
flammable and or explosive, strict safety procedures
must be applied.

PREVENT EXCESSIVE EXTERNAL
PIPE LOAD. Do not use pump as a support for piping.
Do not mount expansion joints, unless allowed by
Flowserve in writing, so that their force, due to internal
pressure, acts on the pump flange.

NEVER RUN THE PUMP DRY. Use
diamond-like-coated (DLC) parts for additional
protection from dry running. DLC does not guarantee
dry run protection.

Never start this pump without proper prime

(casing must be full of liquid).

START THE PUMP WITH THE
DISCHARGE VALVE PARTLY OPENED (Unless
otherwise instructed at a specific point in the User
Instructions.) This is recommended to minimize the risk
of overloading and damaging the pump or motor at full
or zero flow. Pumps may be started with the valve
further open only on installations where this situation
cannot occur. The pump outlet control valve may need
to be adjusted to comply with the duty following the run­up process. (See section 5, Commissioning start-up,
operation and shutdown.)

SUCTION VALVES TO BE FULLY OPEN WHEN
PUMP IS RUNNING
Running the pump at zero flow or below the
recommended minimum flow continuously will cause
damage to the pump. Never operate this pump with the
suction and / or discharge valve closed as this may lead
to high surface temperatures.

The direction of rotation is clockwise
when viewed from the motor end. Rotation of the motor
must be checked prior to starting the pump according to
section 5.1.

DO NOT RUN THE PUMP AT
ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a flow rate higher than normal or at a flow
rate with no back pressure on the pump may overload
the motor and cause cavitation. Low flow rates may
cause a reduction in pump/bearing life, overheating of
the pump, instability and cavitation/vibration.

NEVER EXCEED THE MAXIMUM
DESIGN PRESSURE (MDP) AT THE TEMPERATURE
SHOWN ON THE PUMP NAMEPLATE AND
INCLUDED IN SECTION 3.5.2.

Never loosen flange connection while system is

under pressure.

Always make certain pressure gages,

indicating lights and safety devices are working.

ALWAYS know the EMERGENCY STOP location

for the pump.

Page 6 of 40

Driver may overload and de-couple if
pumpage specific gravity is greater than originally
assumed. Prolonged running while de-coupled will
damage driver and impeller magnets.

Decoupling the pump may lead to increased

surface temperatures.

without approval of authorized Flowserve distributor.

Excessive amounts of dust collected on the
pump housing may lead to an increase in surface
temperature, possibly exceeding temperature limits.
May require regular cleaning.

Always have this service manual available during any
installation or maintenance.

1.6.4 Products used in potentially explosive
atmospheres

Measures are required to:

 Avoid excess temperature
 Prevent build up of explosive mixtures
 Prevent the generation of sparks
 Prevent leakages
 Maintain the pump to avoid hazard

The following instructions for pumps and pump units
when installed in potentially explosive atmospheres
must be followed to help ensure explosion protection.
For ATEX, both electrical and non-electrical equipment
must meet the requirements of European Directive
2014/34/EU (previously 94/9/EC which remains valid
until April 20th 2016 during the transition). Always
observe the regional legal Ex requirements eg Ex
electrical items outside the EU may be required certified
to other than ATEX eg IECEx, UL.

1.6.4.1 Scope of compliance

Use equipment only in the zone for which it is
appropriate. Always check that the driver and pump
equipment are suitably rated and/or certified for the
classification of the specific atmosphere in which they
are to be installed.

Where Flowserve has supplied only the bare shaft
pump, the Ex rating applies only to the pump. The
party responsible for assembling the ATEX pump set
shall select the coupling, driver and any additional
equipment, with the necessary CE Certificate/
Declaration of Conformity establishing it is suitable for
the area in which it is to be installed.

The output from a variable frequency drive (VFD) can
cause additional heating effects in the motor and so,
for pumps sets with a VFD, the ATEX Certification for
the motor must state that it is covers the situation
where electrical supply is from the VFD. This
particular requirement still applies even if the VFD is
in a safe area.

1.6.4.2 Marking

An example of ATEX equipment marking is shown
below. The actual classification of the pump will be
engraved on the nameplate.

(see section 1.6.4.3.)

1.6.4.3 Avoiding excessive surface
temperatures

ENSURE THE EQUIPMENT TEMPERATURE

CLASS IS SUITABLE FOR THE HAZARD ZONE
Pumps have a temperature class as stated in the

ATEX Ex rating on the nameplate. These are based
on a maximum ambient of 40 ºC (104 ºF); refer to
Flowserve for higher ambient temperatures.

The surface temperature on the pump is influenced
by the temperature of the liquid handled. The
maximum permissible liquid temperature depends on
the ATEX temperature class and must not exceed the
values in the table that follows.

Maximum permitted liquid temperature for pumps

* The table only takes the ATEX temperature class into consideration. Pump
design or material, as well as component design or material, may further
limit the maximum working temperature of the liquid.

Page 7 of 40

U-MAG ENGLISH 26999990 10-14

The temperature rise at the bearings and due to the
minimum permitted flow rate is taken into account in
the temperatures stated.

The operator is responsible to ensure that the
specified maximum liquid temperature is not
exceeded.

Temperature classification “Tx” is used when the liquid

temperature varies and when the pump is required to be
used in differently classified potentially explosive
atmospheres. In this case the user is responsible for
ensuring that the pump surface temperature does not
exceed that permitted in its actual installed location.

Avoid mechanical, hydraulic or electrical overload by
using motor overload trips, temperature monitors
and/or a power monitor and make routine vibration
monitoring checks.

In dirty or dusty environments, make regular checks
and remove dirt from areas around close clearances,
bearing housings and motors.

Where there is any risk of the pump being run against a
closed valve generating high liquid and casing external
surface temperatures fit an external surface
temperature protection device.

1.6.4.4 Preventing the build-up of explosive
mixtures

ENSURE THE PUMP IS PROPERLY FILLED

AND DOES NOT RUN DRY
Ensure the pump and relevant suction and discharge

pipeline system is totally filled with liquid at all times
during the pump operation, so that an explosive
atmosphere is prevented.

If the operation of the system cannot avoid this
condition, fit an appropriate dry run protection device
(for example liquid detection or a power monitor).

To avoid potential hazards from fugitive emissions of
vapor or gas to atmosphere the surrounding area
must be well ventilated.

1.6.4.5 Preventing sparks

To avoid the potential hazard from random
induced current generating a spark, the baseplate
must be properly grounded.

Avoid electrostatic charge: do not rub non-metallic

surfaces with a dry cloth; ensure cloth is damp.

Additional requirement for metallic pumps on
non-metallic baseplates

When metallic components are fitted on a non­metallic baseplate they must be individually earthed.

If so equipped, to prevent a potential hazard from
mechanical contact, the coupling guard must be non­sparking. For ATEX the coupling must be selected to
comply with European Directive 2014/34/EU
(previously 94/9/EC which remains valid until April
20th 2016 during the transition). Correct coupling
alignment must be maintained.

1.6.4.6 Preventing leakage

The pump must only be used to handle liquids
for which it has been approved to have the correct
corrosion resistance.

Avoid entrapment of liquid in the pump and associated
piping due to closing of suction and discharge valves,
which could cause dangerous excessive pressures to
occur if there is heat input to the liquid. This can occur if
the pump is stationary or running.

Bursting of liquid containing parts due to freezing
must be avoided by draining or protecting the pump
and ancillary systems.

If leakage of liquid to atmosphere can result in a
hazard, install a liquid detection device or secondary
containment.

1.6.4.7 Maintenance to avoid the hazard

CORRECT MAINTENANCE IS REQUIRED TO
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION

The responsibility for compliance with maintenance
instructions is with the plant operator.

To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
adversely affect the ambient conditions. Where there
is a risk from such tools or materials, maintenance
must be conducted in a safe area.

It is recommended that a maintenance plan and
schedule is adopted. (See section 6, Maintenance.)

1.7.2 Safety labels

to control the exposure time to the noise or to enclose
the machine to reduce emitted sound.

You may have already specified a limiting noise level
when the equipment was ordered, however if no
noise requirements were defined, then attention is
drawn to the following table to give an indication of
equipment noise level so that you can take the
appropriate action in your plant.

Pump noise level is dependent on a number of
operational factors, flow rate, pipework design and
acoustic characteristics of the building, and so the
values given are subject to a 3 dBA tolerance and
cannot be guaranteed.

Similarly the motor noise provided in the table below is

“pump and motor” noise that is typically expected from

standard and high efficiency motors when on load
directly driving the pump. Note that a motor driven by
an inverter may show an increased noise at some
speeds.

If a pump unit only has been purchased for fitting with
your own driver, then the noise levels in the table should
be adjusted for the driver level obtained from the
supplier. Consult Flowserve or a noise specialist if
assistance is required in adjusting the values.

It is recommended that where exposure approaches
the prescribed limit, then site noise measurements
should be made. The values are in sound pressure
level LpA at 1 m (3.3 ft) from the machine, for “free
field conditions over a reflecting plane”.

1.8 Specific machine performance

For performance parameters see section 1.5, Duty
conditions. Where performance data has been supplied

separately to the purchaser these should be obtained
and retained with these User Instructions.

1.9 Noise level

Attention must be given to the exposure of personnel
to the noise, and local legislation will define when
guidance to personnel on noise limitation is required,
and when noise exposure reduction is mandatory.
This is typically 80 to 85 dBA. The usual approach is

Page 9 of 40

Notes: (1.) values are for the maximum usable motor size (2.) for
1180 and 960 rpm reduce 1450 rpm values by 2 dBA. For 880 and
720 rpm reduce 1450 rpm values by 3 dBA. (3.) Choosing a fan­cooled motor will increase noise levels. (4.) Placing valves, orifices,
or flow meters near a pump will increase noise levels inside the
pump.

For estimating sound power level LWA (re 1 pW) then
add 14 dBA to the sound pressure value.

2 TRANSPORT AND STORAGE

2.1 Consignment receipt and unpacking

Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for

U-MAG ENGLISH 26999990 10-14

its completeness and that there has been no damage
in transportation. Any shortage and/or damage must
be reported immediately to Flowserve and must be
received in writing within one month of receipt of the
equipment. Later claims cannot be accepted.

Check any crate, boxes or wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to side
walls of the box or equipment.

Each pump/wet end has a unique serial number.
Check that this number corresponds with that
advised. Always use this number in correspondence
and when ordering spare parts or further accessories.

2.2 Handling

Boxes, crates, pallets or cartons may be unloaded
using fork lift vehicles or slings dependent on their
size and construction.

2.3 Lifting

A crane must be used for all pump sets or
components in excess of 25 kg (55 lb.). Fully trained
personnel must carry out lifting, in accordance with
local regulations. Slings, ropes and other lifting gear
should be positioned where they cannot slip and
where a balanced lift is obtained. The angle between
sling or ropes used for lifting must not exceed 60°.

Figure 2-1

2.3.2 Lifting pump and motor assembly

For pump and motor, sling around the pump discharge
nozzle, and around the outboard end of the motor frame
using choker hitches pulled tight. The sling should be
positioned so the weight is not carried through the
motor fan housing. (Figure 2-2)

Figure 2-2

To avoid distortion, the pump unit

should be lifted as shown.

Pumps and motors often have integral
lifting lugs or eye bolts. These are intended for use in
only lifting the individual piece of equipment.

Do not use eye bolts or cast-in lifting
lugs to lift pump, motor and baseplate assemblies.

Care must be taken to lift components
or assemblies above the center of gravity to prevent
the unit from flipping.

2.3.1 Lifting Wet-End

The wet end should be lifted by sling around the pump
discharge nozzle using a choker hitch pulled tight as
shown in Figure 2-1.

2.3.3 Lifting pump, motor and baseplate
assembly

If the baseplate has lifting holes cut in the sides at the
end (Type D, Type E bases and Type A when provided)
insert lifting S hooks at the four corners and use slings
or chains to connect to the lifting eye. Do not use slings
through the lifting holes.

For other baseplates, sling around the pump discharge
nozzle, and around the outboard end of the motor frame
using choker hitches pulled tight. The sling should be
positioned so the weight is not carried through the
motor fan housing. (Figure 2-3)

Assembled units and their
components are heavy. Failure to properly lift and
support this equipment can result in serious physical
injury and/or equipment damage. Lift equipment only
at the specifically identified lifting points. Lifting
devices such as eyebolts, slings, and spreaders must
be rated, selected, and used for the entire load being
lifted.

Crush hazard. The unit and the components can
be heavy. Use proper lifting methods and wear steel­toed shoes at all times.

Do not attach sling ropes to shaft

ends.

Make sure that the unit cannot roll or

fall over and injure people or damage property.
These pumps use carbon or ceramic silicon carbide

components. Do not drop the pump or subject it to
shock loads as this can damage the internal ceramic
components.

2.4 Storage

Store the pump in a clean, dry location
away from vibration. Leave piping connection covers
in place to keep dirt and other foreign material out of
pump casing.

The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.

2.5 Recycling and end of product life

At the end of the service life of the product or its
parts, the relevant materials and parts should be
recycled or disposed of using an environmentally
acceptable method and local requirements. If the
product contains substances that are harmful to the
environment, these should be removed and disposed
of in accordance with current regulations.

Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
regulations at all times.

3 DESCRIPTION

3.1 Configurations

The U-MAG™ chemical process pumps are
fluoropolymer lined, magnetically coupled, single
stage, centrifugal pumps.

3.2 Nomenclature

The pump size will be etched on the nameplate as in
this example: U012511100-UB0. See Figure 3-1 for
pump identification codes.

3.3 Nameplate

Every U-MAGTM pump unit has a nameplate to
provide information on your pump. The nameplates
are located on the adapter with a second tag
containing just the pump serial number affixed to the
casing discharge flange. It is recommended that the
purchaser record the serial number and use it for
reference when requesting information, service, or
parts from your supplier.

Permanent records for this pump are kept by the
serial number and it, therefore, must be used with all
correspondence and spare parts orders. Tag includes
the following:

 Pump Model Number: Example – U0
 Pump Code: Example – U013711100-UB0
 Serial Number: Example – 44001
 Impeller Diameter / Max Impeller Diameter

(mm or in.)

 Duty Point (Flow/TDH)( m3/hr / m or US gpm

/ ft.)

 Process Liquid Specific Gravity and

Temperature (°C or °F)
