about seal abrasion and motor damage.

SUBMERSE is oil free.

Besides, it is not needed to worry about contaminationby oil or waste water for no oil leakage from sealling.

The sealless magnet drive pump does not have a oil bath type mechanical seal and no need to worry
about oil leakage. It is a safety pump without contamination by oil.

YD-25A6GWN1 <Bore 25A> <1PH / 100V, 0.26kW>■ Disk type magnet drive■ Possible to absorb at a minimum liquid level of 10mm.

Basically, the coupling of the horizontal magnet pump is the outer of the columnar
passive mange (impeller at the side of the pump) and the bowl-shaped magnet at theside of the motor. Therefore, it was said that the magnet drive is diﬃcult to be used fora submersible pump which is easly locked by air and vulnerable for slurry, because It
has a complicated water pass.
However, World Chemical Co., Ltd. adopts “disk type magnet drive” that two
disk-shaped magnets rotate among a hard ceramic separating board. The simple waterpass attaines the pump prevent air lock and slurry.

Now it is possible to completely absorb liuqid by changing the sape of the suction
inlet. Even if the pump is not immediately stopped while the liquid is completely
absorbed, there is no need to worry about malfunction due to heat generation.

Short-term completely absorbed
operation is available!
10mm■ Speciﬁcation for high temperature liquid
The insulation is H type and it is possible to use the pump for the liquid until 70 degrees
as standard. SUBMERSE is active in using for high temperature & easy bubbling liquid
or pumping from a deep pit which is the hard to use for a self-priming pump.

■ 100V, 1PH
Trouble wire works are unnecessary and anywhere to use.

Can use the pump soon at the emergency.

※ Do not use the attached PVC valve socket when the liquid temperature is 50 degrees and more.
Remove the valve socket and do other plumbing. The change to a HT-PVC valve socket which is heat
resistant is also available as an optional extra.

The pump can be used for acid and alkali, because the pump body is made of CFR PP (Carbon ﬁber reinforced polypropylene) andthere is no metal parts for the wet parts kit.
However, it may be corrosive depending on concentration and temperature of liquid. (Ex. Sulfuric acid, Nitric acid, hydroﬂuoric acid,
Chromic acid, sodium hypochlorite)
Ask us about corrosion resistance.
It is used for the body of SUBMERSE and possible to use for general acid and alkali, but may be corroded by sulfuric acid, nitricacid, hydroﬂuoric acid, chromic acid, sodium hypochlorite depending on the concentration. Ask us when using the pump forthe above liquid.

How to check the rotating directionN

1. SUBMERSE is magnet drive system. If dry running occurs, the bearing and shaft may be damaged and the plastic parts may be deformed byheat. Three phase pump may rotate in reverse depending on the wiring conneciton. If in reverse, the pumping volume and discharge pressure
are decreased approx. 30% compared to the possitive rotation. Since the current value shows a low value, the negative rotation can be
conﬁrmed. However, if it is not possible, turn on /oﬀ the pump instatly while hanged and submerged as referred Picture ① to conﬁrm recoil
direction.
2. When it is right, the pump moves to left direction as veiwed from the above such as Picture ② at the moment it starts.（Be careful of liuqid
blowout from the discharge piping while checking.）

precautions

The standard type pump can be used for liquid until 40℃.
1. The incorporated thermal protector works and the pump may stop to protect the motor depending on the operational condition.
In this case, stop the operation for a while and check there is no problem with the pump.
Make sure to check that the aprropriate liquid level is ensured when restarting the operation.
2. Do not disassemble the motor and connection of the cabtire cable. It may lead to the accident by electric leakage.

Minimum required ﬂow at an operation: 5 L/min.
Minimum liquid level at continuous operation is 400 mm. (The motor fully submerged)
Minimum operable liquid level is 100 mm.
