Warning
When using for dangerous liquid or in atmospheres
When using the pump for dangerous liquid or in potentially explosive atmospheres (only explosion- proof
type), adhere to facility standards determined by law and check no liquid leak daily. If the pump is
operated under abnormal conditions such as liquid leak, it leads to explosion, fire or personal injuries.
Follow the manufacturers’instructions about handling the liquid.
Banning the use of damaged or modified pumps
If using the damaged of modified pump, it may cause personal injuries, electric shock or the pump
damage. They are not covered by warranty.
Caution in transporting and lifting pumps
Use the hoist bolt when lifting a pump. If it does not own the hoist, use a belt sling and lift the pump with
careful attention to the weight balance. Perform it by qualified personnel with the strong enough sling. The
weight of the lightest pump is approx. 23kg at least. Do not carry a pump by hand as much as possible,
because it may cause an accident.
Banning the operation with the power on
Do not check or disassemble a pump or motor while the power on. It leads to personal injuries from
electric shock or getting caught in the rotor. Take the multiple safety precaution such as the switch for
main power supply, the operation switch, and the hand switch for the pump.
Connection of an earth wire
Using the pump without connecting an earth wire may cause electric shock. Perform the connection by a
qualified person according to the electric facility’s technical standards and interior wiring regulations.
Protection of the power supply cord.
If stretching, pinching or damaging the power supply cords or motor lead wires, it causes fire or electric
shock for the damaged cable. Install the cover of the terminal box in its proper position after wiring.
Ground Fault Interrupter (GFI)
If using a pump without a ground fault interrupter device, it may cause electric shock. Prevent the
electric accidents and the pump damages applying circuit breakers, over-current protection devices
and/or other protective devices.
Caution in removing a pump
When removing a pump from pipes, close the suction and discharge pipe valves and check no liquid leak.
If direct contact with liquid, it may cause injury.Always wear protective gear when performing operations.

◼Features / Precautions in handling / Temperature to use
SUBMERSE is constructed of Carbon Fiber Reinforced Polypropylene and a corrosion resistant ceramic
shaft. Additionally, the structure is a magnet drive type which does not require a shaft seal. It makes the
submersible pump use for strong acids and alkalis that the pump did not use to be used for.
1. All wet kit parts are made of corrosion resistant resin and ceramic.
2. The pump can be used for strong acids and alkalis.
3. It is a magnet drive structure which does not require a shaft seal. The liquid enters into the motor.
4. There is little consumables and it is easy to replace parts.
5. Operation of the pump is as simple as lowering it into a tank. It is also possible to operate with
hanging.
6. The pump has a handling for carrying and be suitable for emergency use.
7. There is a ceramic plate between the motor and pump chamber to be resistant to heat and chemical.
8. A thermal protector is incorporated. If overload occurs from any cause, the motor is stopped by the
thermal protector.
◼Precautions in handling
1. Slurry accelerates the bearing worn. Especially when the pump is used in a settling tank, mount the
pump to prevent slurry entering or clear slurry. (Replacement of the bearing is easy and use the
ceramic bearing for liquid with slurry.)
2. Completely submerge the pump to use. Operation in air causes the pump damage.
3. Operation with the check valve at the discharge pipe leads dry running not to release air. Install the
air release pipe beneath the check valve and always release air.
4. If the pump is exposed from liquid, the motor resin cover may be damaged because the motor is not
cooled.
5. It may cause dry running for the failure of the liquid level gauge. Check it before use.
6. Make sure to put the strainer to prevent dirt and always clean it not to be clogged. If it is clogged, the
pump may burn not to pump.
7. When extending the electric wire, consider the diameter to prevent to decrease the voltage.
8. The temperature of the liquid is high (55C/131F degrees and more), change the material of the valve
socket (PVC) at the discharge outlet. (HT-PVC is recommended.)
9. Do not use the pump for highly concentrated sulfuric acid (50% and more).
◼Temperature to use

◼Minimum liquid level during operation / Example of installation / Model description
Minimum liquid level during continuous operation is 400 mm.
Keep the liquid depth during operation that the whole pump is submerged.
Operation under the liquid level of the continuous operation for dead head operation is within 5 minutes.
Do not short operation repeatedly.
⚫The thermal protector may work to protect the motor according to conditions in the operation and
the pump may stop. In this case, stop the operation for a while. Ensure the liquid level is properly
and start the operation after checking whether the pump is normal.
Minimum liquid level during operation is 130 mm.
⚫Even if the operational liquid level is correct, the operation error may occur to the air entering by the
condition of the liquid level.
⚫If the impeller is operated in the air, the rotating parts may be damaged.

◼Precautions in operation
1. Electric wiring
Before starting operation, check the rotational direction. When U (red), V (white), W (black), and earth
(green) are connected, the pump starts. Checking the rotational direction is as follows.
1-(1) In case of the inverse rotation, the capacity is only 30% of the forward rotation.
1-(2) When turning on the switch with lifting the pump in water, a counterclockwise back action is in
the forward direction.
Note: In case of the inverse rotation, switch two of three cables (Rec, White, Black).
2. Precautions in electric wiring
⚫Make sure to connect a green earth wire to a polar plate or bar before connecting the cable to
prevent electric shock.
⚫When it is necessary to be the instantaneous operation to check the rotational direction, never
test the pump in air. Heat makes the pump may deform and causes the failure.
⚫Install a circuit breaker to prevent unexpected problems.
Note: To prevent electrical shock or fire, the user is obligated to provide a leak breaker
according to the industrial safety and Health Regulation and Electric Equipment Technical
Standard. (Japan)

3. Voltage during operation
When the voltage is low, the current increases. In this case, the thermal protector works as the
temperature of the stator is raised. The low voltage causes the performance failure. Use the pump
with the voltage within the specified range.
Note: The applicable voltage for this pump is within ±10％of the rated voltage.
4. Thermal protector (Protection Instrument)
When the temperature of the motor coil is near burning temperature for electrical or mechanical
causes, the burn protection function works and stops the motor by cutting off the electrical circuit. At
this time, carefully check the operated cause of the thermal protector, and remove it before resuming
operation.
Note: Make sure to turn off the power before check. The thermal protector automatically
restart.
