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, which makes
the submersible pump compatible with strong acid and strong alkaline liquids that the previous pumps
could not handle.
1. All the wet parts are made of corrosion resistant resin and ceramic.
2. The pump can be used for strong acid and alkaline liquids.
3. It is a magnet drive structure which does not require a shaft seal. Liquid will not enter the motor.
4. There are little consumables and parts are replaceable.
5. Operation of the pump is as simple as placing it in a tank. It also can be mounted in a hanging
position.
6. Easy grip for carrying, and durable construction ideal for emergency purpose.
7. A ceramic plate is used between the motor and pump chamber, which makes it resistant to both heat
and chemicals.
8. A thermal protector is incorporated. If motor overload is detected from any cause, the thermal
protector is activated to stop the motor.

Precautions in handling
1. Slurry will accelerate bearing wear. Especially when the pump is used in a sedimentation tank, mount
the pump to prevent slurry from entering the pump, or clean any slurry before reaching the pump.
(Replacement of the bearing is easy. Use a ceramic bearing on liquids with slurry.)
2. Completely submerge the pump to use. Operation with air may cause pump failure.
3. If the check valve is attached at the discharge pipe, air will not be released, which will cause dry
running. If you attach the check valve, install the air release pipe beneath to always release air.
4. If the pump is not completely submerged in liquid and exposed to air, the motor will not cool down,
causing a damage to the motor resin cover.
5. A liquid level gauge malfunction can cause dry running. Check before the operation.
6. Make sure to attach the strainer to the pump in order to prevent debris from entering, and always
clean it to be clog-free. If it is clogged, the pump may overheat.
7. When considering electric wiring, ensure the wiring gauge is adequate to prevent voltage drop.
8. When the liquid temperature is high (131F/55C degrees and higher), change the material of the valve
socket (PVC) at the discharge outlet. (High temperature- PVC is recommended.)
9. Do not use the pump for highly concentrated sulfuric acid (50% and more).
