Do not use liquid type sealant. Avoid using too much sealant tape. Excess use of
sealant tape may result in over-torque and damage the port.
Do not attempt to flush out piping if already assembled with the pump.
Airtight test must be completed before installation.
Do not run the pump in reverse direction.
Do not run the pump dry over 10 second
Be sure to bleed an outlet piping of air on a initial run.
If any abnormalities are discovered, stop the pump immediately and inspect for the
defective areas. (See Table 5 P.19)
Do not run the pump over the maximum pressure setting.
Do not remove the return pipe, or it may cause foam and abnormal sounds
Consult your coolant manufacturer (or distributor) for the compatibility with fluoro
carbon rubber, the material of the pump seal, in advance to avoid leakage.
Operate the pump within the specified temperature range.
See “Operating Ambient Temperatures” and “fluid temperature range” on P.16
Keep the viscosity of your coolant within the specified range.
See “Table 4 : Compatible Coolant Type and Viscosity Range on P.16.
Do not use work materials harder than HV600. Extremely hard materials, such as
Inconel, Titanium, Tungsten, can drastically shorten the pump service-life.
Do not use hardened steel, carbon fiber, glass fiber containing materials, carbon
materials. Those materials can drastically shorten your pump service-life.
Do not use film or resin coating materials. Those materials can lead to poor filter
performance and Turbulence filter clogging
Do not operate the pump in a fluid containing a large amount of grindstones or
abrasive grains. They can drastically shorten your pump service-life.
Do not apply wrong supply voltage or frequency.
Keep the motor rotation speed within the specified range. (1000 min
-1
to 2000 mm
-1
)
Make sure that there is no excess resistance in outlet line. It will affect the pump
suction performance.
Make sure there is no trapped air in inlet line. It may decrease the performance of
Turbulence filter, cause filter clogging and damage the pump.
Clean the perforations of the inlet port at regular intervals. Clogged inlet will cause
abnormal noise, vibration, discharge failure, which result in the pump damage.
Make sure there is no tramp oil accumulation or foam on the coolant surface.
Backwashing will not recover filtration performance of a pump completely.
Constant filter clogging suggests that the pump might be operated beyond the
specifications.
