Important Safety Precautions

● Matters falling under the following may not be cov-ered by the warranty: uses out of the specified scope of application, failure to comply with precau-tions, improper repairs and alterations, matters aris-ing from natural disasters, matters arising from the installation environment (improper power source, foreign objects, sand etc.), non-compliance with laws and regulations or standards pertaining there-to, accidental or intentional damage or injury, replacement of consumable parts, defects due to resale, etc.

● Do not use the product for applications out of the product specifications. Doing so may cause electri-cal shock, fire, liquid leakage, etc.

● Close attention is needed when rusting, corrosion /elution are not permissible owing to the applica-tion or liquid properties. Take into account both the pump and the rest of the equipment when consid-ering and selecting.

● Select a product which is appropriate for your ap-plication. Inappropriate use of products may cause accidents.

● Have spare equipment ready when using pumps for critical equipment.

● Conduct construction in accordance with the appli-cable laws and regulations (the Technical Standards of Electric Installation, interior wiring regulation, Building Standards Act, etc.). Not only does it vio-late the laws and regulations, but it also may cause injuries due to electric shock, fire, falling and tip-ping over.

● Observe the service life of the pump, install it in a well ventilated place free from corrosive or explo-sive gases, salt, moisture, water vapor, condensa-tion etc., and avoid exposing it to wind, rain and direct sunlight. In a harsh environment, electric leakage, electric shock or fire may result from dete-rioration of insulation in the motor or control panel, etc.

● Install buzzers, etc., as an alarm to alert failure to be noticed. Failing to do so may result in serious acci-dents without noticing a failure.

● Do not install in places with no drainage or places which have not been waterproofed. Liquid leaks may cause serious damage.* We bear no responsibility for any damage arising

from lack of drainage or waterproofing.● Depending on the equipment, attach a filter etc. ap-

propriate for your application on the discharge side before use, perform thorough flushing and check that there is no contamination. Cutting oil, rubber mold releasing agent, foreign objects etc. from the manufacturing line and cutting oil, foreign objects etc. from the pipeline may contaminate the liquid which is to be handled.

● Do not operate pumps with a specification of 50 Hz at 60 Hz. Damage may arise as a result of excess pressure or burnout of the motor etc. due to over-load.

● Do not place flammables near or cover the sur-roundings of the pump, cable, control panel and inside the pump cover with combustibles. This may cause fires due to heating.

● The Pump should never be disassembled, repaired, or modified, or the power cable should never be replaced by anyone other than a qualified repair technician. Improper repairs could result in electric shocks, fires, faults or break

● It is recommended that both periodic and daily inspections be performed in order to ensure that the pump will operate reliably for as long as possi-ble. Failure to perform inspections may lead to pump failure, accidents etc. For periodic inspec-tions, please consult your distributor or our nearest sales office.

Blank : standard4 Leg length A: standard B: long leg

■Model Explanation

Kawamoto’s uniquesealless structure

Optimum gap at shaft seal parts ensuresimproved sealing. Pressure drops areminimized, ensuring long-term use.

Highly durable quenched materials have been used for the shaft sealing section. Moreover, the environmental burden has been reduced through a design which allows replacement of the shaft sealing section alone if liquid leaks have become frequent as a result of wear.

●Two types of leg length

Two types of leg length are available depending on tank depth.*Refer to the page 7 for detailed dimensions.

■Standard Specifications

Shaft seal parts offer protection from coolant splashes with the first anti-splash cover (see following Fig.1), and sealing has been improved with the adoption of a unique sealless structure. The pump has been enclosed with a second anti-splash cover (see following Fig.2) to protect it from coolant splashes.

■Unique double anti-splash structure

●Sleeve (rotating ring) : Quenched SUS440●Bush (securing ring) : Quenched S45C

●Mating flange set*Please contact distributor or Kawamoto pump if neccessary.

Direction of coolant flowSludge(cutting chips)

■Strong impellerSemi-open impellers (double blades) increase the area of the water channel and prevent sludge (cutting chips) from clogging. They also reduce collision of sludge (cutting chips) with the blades and extend the service life.

■Outstanding maintainability1 Resistant to sludge (cutting chips), because

mechanical seals are not used.2 Anti-clogging, because there is no strainer

at the suction inlet.

■Unique casing formBecause the structure adopts an inclined sludge guide casing form in which sludge (cutting chips) passes through easily without frequently colliding into the casing wall, it also has outstanding durability.

Important Safety Precautions

● Matters falling under the following may not be cov-ered by the warranty: uses out of the specified scope of application, failure to comply with precau-tions, improper repairs and alterations, matters aris-ing from natural disasters, matters arising from the installation environment (improper power source, foreign objects, sand etc.), non-compliance with laws and regulations or standards pertaining there-to, accidental or intentional damage or injury, replacement of consumable parts, defects due to resale, etc.

● Do not use the product for applications out of the product specifications. Doing so may cause electri-cal shock, fire, liquid leakage, etc.

● Close attention is needed when rusting, corrosion /elution are not permissible owing to the applica-tion or liquid properties. Take into account both the pump and the rest of the equipment when consid-ering and selecting.

● Select a product which is appropriate for your ap-plication. Inappropriate use of products may cause accidents.

● Have spare equipment ready when using pumps for critical equipment.

● Conduct construction in accordance with the appli-cable laws and regulations (the Technical Standards of Electric Installation, interior wiring regulation, Building Standards Act, etc.). Not only does it vio-late the laws and regulations, but it also may cause injuries due to electric shock, fire, falling and tip-ping over.

● Observe the service life of the pump, install it in a well ventilated place free from corrosive or explo-sive gases, salt, moisture, water vapor, condensa-tion etc., and avoid exposing it to wind, rain and direct sunlight. In a harsh environment, electric leakage, electric shock or fire may result from dete-rioration of insulation in the motor or control panel, etc.

● Install buzzers, etc., as an alarm to alert failure to be noticed. Failing to do so may result in serious acci-dents without noticing a failure.

● Do not install in places with no drainage or places which have not been waterproofed. Liquid leaks may cause serious damage.* We bear no responsibility for any damage arising

from lack of drainage or waterproofing.● Depending on the equipment, attach a filter etc. ap-

propriate for your application on the discharge side before use, perform thorough flushing and check that there is no contamination. Cutting oil, rubber mold releasing agent, foreign objects etc. from the manufacturing line and cutting oil, foreign objects etc. from the pipeline may contaminate the liquid which is to be handled.

● Do not operate pumps with a specification of 50 Hz at 60 Hz. Damage may arise as a result of excess pressure or burnout of the motor etc. due to over-load.

● Do not place flammables near or cover the sur-roundings of the pump, cable, control panel and inside the pump cover with combustibles. This may cause fires due to heating.

● The Pump should never be disassembled, repaired, or modified, or the power cable should never be replaced by anyone other than a qualified repair technician. Improper repairs could result in electric shocks, fires, faults or break

● It is recommended that both periodic and daily inspections be performed in order to ensure that the pump will operate reliably for as long as possi-ble. Failure to perform inspections may lead to pump failure, accidents etc. For periodic inspec-tions, please consult your distributor or our nearest sales office.
