leakage occurs.
Operation
 Absolutely do not touch or come close to turning parts. Doing so could result
in injury caused by entanglement in the rotating parts.
 In case of power failure, be sure to turn the power off to prevent the pump
from starting unexpectedly when the power is restored.
Maintenance and Inspection
 Be sure to connect the power cable in accordance with instruction manual
for the motor and the connection diagram in the terminal box. Failure to do
so could result in electrical shock or fire.
 Magnet drives cause strong magnetic fields. Persons with a pacemaker
should not stay close to the magnet drive or come into close bodily contact
with parts of it.

3
General
 If using in connection with the food processing, be sure to keep the pump
clean by washing. Failure to do so could enable germs to develop in the
pump.
 Do not insert your fingers or any other objects in the openings of the pump
motor. Doing so could result in electrical shock, injury or fire.
Installation and Adjustment
 Absolutely do not place inflammable materials in the area surrounding the
pump. Doing so could result in fire.
Operation
 Be careful of rotating parts.
Do not insert your fingers, etc., in the openings of the frame adaptor while
the pump is operating. Touching turning parts could result in injury.
Disassembly and Assembly
 Be careful with hazardous liquids.
If pumping dangerous chemicals, be sure to drain and wash well before
disassembling. A small amount of fluid may however remain in the screw,
faucet joint and engaged parts inside the pump.
If handling hazardous chemicals, be sure to wear protective equipment
such as glasses and rubber gloves, and proceed with caution while disas-
sembling the pump.
 Be careful not to get your hands or fingers pinched by machine parts.
Parts may be strongly attracted by magnetism when disassembling or as-
sembling the magnet coupling. Be careful not to let your hands or fingers
get pinched by magnetized parts.

General
 Transport, installation, piping and wiring connections, operation, adjust-
ment, maintenance and inspection should be carried out by qualified per-
sonnel. Having unqualified personnel perform these tasks could result in
electrical shock, injury or fire.
 Be sure to use only a power source of the voltage indicated on the name
plate of the motor. Not doing so could result in electrical shock, injury or
equipment damage.
 Do not use a damaged motor. Doing so could result in injury or fire.
 The customer should not modify the pump under any circumstances. Doing
so could result in an unexpected accident. Sanwa Hydrotech shall not be
responsible for accidents or damage resulting from equipment modified by
the customer.
 Do not block name plate or warning labels from view.
 Do not remove the name plate or warning labels.
Transport
 Beware of equipment falling or turning over during transport. Be sure to
use the hanger bolt if the pump is equipped with one. After installation,
however, you should avoid hoisting the entire machine by the hanger bolt.
Before lifting, check the weight of the pump by referring to the catalog, etc.
Do not lift a pump which exceeds the rated weight of the hoist. Doing so
could result in injury or equipment damage caused by bolt damage, falling
or turning over.
 The pump bearing is made of extremely rigid material, and cannot endure
rigorous vibration. The pump should be handled with care during
transport. The pump should also be handled with care when installing.
Unpacking
 Check the top and bottom of the package before unpacking. Failure to do so
could result in injury.
 Check the delivery specifications and name plate to make sure the mer-
chandise is as ordered. Installing the wrong equipment could result in in-
jury or equipment damage.

5
Piping and Wiring
 Be sure to connect the power cable in accordance with instruction manual
for the motor and the connection diagram in the terminal box. Failure to do
so could result in electrical shock or fire.
 Do not forcibly bend, pull or crimp the power cable or motor lead wires.
Doing so could result in electrical shock.
Installation and Adjustment
 Be sure to connect the earth terminal securely. Failure to do so could result
in electrical shock.
Operation
 Do not operate with the terminal box cover off. After wiring, be sure to re-
place the terminal box cover in its original position. Failure to do so could
result in electrical shock.
 Beware of high temperatures.
If handling high temperature fluids, do not place your hands, etc., near the
casing or frame adapter. Doing so could result in skin burning.
 Do not operate the pump to pumping gases. This pump is designed to pumping
liquids. Otherwise, the pump may have a high temperature or SiC bearings and
the rear casing shell may be broken.
 No-Load Operation
Absolutely do not operate the pump without a load. Doing so will cause the
inside to heat up and damage the bearings. Never operate the pump with-
out liquid inside of the pump. (This applies to when checking rotation di-
rection as well.) If heat is produced in the can, the temperature rises may
cause magnetism to reduce.
 Shut-Off Operation
Do not perform shut-off operation for more than one minute. Doing so will
cause a radical rise in temperature of the liquid in the pump, and could
result in an accident.

6
General
 The magnetic pump is designed for liquid only.
 If the pump is modified or changed without authority and/or other than
original spare parts are used for repair works, the explosion protection will
be forfeited.
Inadmissible mode of operation
 Driving motor must have approval for the use in areas subject to explosion
hazards.
Temperature limits
 When being operated to its designated use, the pump’s maximum surface
temperature must not exceed the temperature category of the explosion
protection zone.
Speed limits
 The maximum allowable speed is 3600rpm. If the pump is operated a speed
exceeding the maximum speed, explosion protection is no longer granted.
 Prior to operating the pump unit with a frequency converter it must be
checked, whether the driving motor is appropriate for that purpose.
Disassembly and Assembly
 Ensure that the driving motor and/or the entire equipment have been ap-
proved for the prevailing explosion protection zone.
 Instruction given in the operation manuals of the driving motor is to be
observed.
 If the pump is fitted with a heating jacket, the temperature of heating me-
dium must not exceed the maximum allowable surface temperature of the
pump.
Operation
 When a pump is operated which has not been completely filled, an ignition
source can develop due to heat input. The pump must be completely filled.
If cannot ensure that, appropriate monitoring must be taken.
 When the pump is operated in the closed circuit system, the temperature of
liquid and the surface of the pump will be increased. Use the monitor to
prevent the pump from excessively heating up.

7
 The situations below will increase the temperature of the pump surface. Do
not operate the pump these situations.
･Shut-off operating ･Low-flow operating ･Dry running
･Operating with “decoupling”
･Operating with “circulation-hole of casing cover and shaft is interrupt-
ed”
Maintenance
 If the clearance between rotating and stationary components is out of lim-
itation, it may happen that these component contact and resulting fric-
tional heat entail excessive temperatures.
 Ensure that the bypass-hole of casing cover and shaft is not interrupted.
 Ensure whether pump parts are not corroded. If corrosion occurred, exam-
ine the change of material. Give priority to experience on selection of ma-
terial.
To Prevent sparks
 To avoid the potential hazards from random induced current generating a
spark, the earth contact on the pump and motor must be used.
 To avoid electrostatic charge, do not rub non-metallic surfaces with a dry
cloth. Make sure the cloth is damp.

● Instructions for Safe Usage
 In order to use your Sanwa Magnet Drive Pump in the manner for which it
was designed, be sure to read through and get a thorough understanding of
the contents of this manual and the installation instructions before at-
tempting to install, operate, perform maintenance or inspections. You should
also have a good understanding of the equipment itself, matters concerning
safe operation and handling, and other matters requiring attention before
attempting to use the pump.
Equipment Failure / Accident Prevention and Safe Operation Checks
 Pre-Operation Checks
The power source, wiring and connection, piping, priming, air purging and
rotation direction should be checked before starting operation.
 Checks for Test Operation and Actual Operation
Current, voltage, suction pressure, discharge pressure, and discharge flow
rate should be checked when starting test or actual operation. The pump
should also be checked for vibration, abnormal noise and leaks when opera-
tion is started.
 Be sure to take special precautions when performing test operation
checks if using hazardous, explosive or inflammable liquids.

11
Precautions When Pumping Special Liquids
 Sanwa pumps are used in various industries. Our stainless steel magnet
drive pumps in particular are frequently used for pumping hazardous liquids,
and fluids which tend to produce food germs. Mishandling in any of these
cases could lead to serious consequences such as bodily injury, loss of life or
property damage. To prevent these from occurring, you should get a thorough
understanding of the information contained herein and use the pump in the
manner for which it was designed.
 Special care and safety equipment are required for the following types of
liquid:
 Liquids which could produce a chemical reaction
 Liquids which could produce germs in connection with food
products, and liquids which are of a dangerous nature
 Liquids which could directly harm the human body
 Preventative measures should be taken to protect special pumps and pumps
used in the main production line from natural disasters, unexpected acci-
dents or equipment failure, the event of which could have a disastrous effect
on your production. If these are impossible, you should keep a spare pump on
hand for emergency use. (A pump with a suitable motor unit will be better.)

12
● Transport and unpacking
1. Transport
 When transporting the pump, be careful not to drop it or let it fall. Take
the appropriate method, such as picking up by two people or lifting by
belt, to avoid risk.
 Make sure the eyebolts (if the pump is equipped with them) are used to
secure the pump during transportation. However, do not use the pump’s
eyebolts to lift a machine after the pump is mounted on it. In case of no
the eyebolt, sling around the pump frame adapter and the motor. Before
suspending the pump, refer to leaflet or drawings to check the weight of
the pump and the motor. Never lift a pump that exceeds the rated load of
your suspension device. If you fail to heed this advice, the eyebolts may
be distorted, and the pump may drop or fall, and this may cause an injury
or damage the pump.
 The pump bearing is made of extremely rigid material, and cannot endure
rigorous vibration. The pump should be handled with care during
transport. The pump should also be handled with care when installing.
2. Unpacking
 Check the top and bottom of the package before unpacking. Failure to do
so could result in injury.
 Check the delivery specifications and name plate to make sure the mer-
chandise is as ordered.
Installing the wrong equipment could result in injury or equipment dam-
age.
