Product specification

For the performance of your pump, refer to the nameplate in terms of total head (HEAD), discharge rate
(CAP.), rated voltage (V), rated current (A), etc. Other specifications are listed in the following table.
Warning
Caution
The user of a standard model shall refer to the columns of standard specification.
Other than the standard model, a modified specification is available as a special
specification on request of the user. Do not use the pump at outside the range of
the specification, such as handling liquid, installing site, and power source.
Operation at outside the specification may cause pump trouble, injury, electric
shock, electric leak, and fire.
Mount a ground fault breaker exclusive to the pump. Recommended one is a
wiring breaker equipped with an electric leak alarm. There is a possibility of
electric shock and fire.
The pump cannot be used for food processing, food transportation, and other
food-relating uses. There is a possibility of generation of various bacteria and of
inclusion of foreign matter.
Do not use the pump at facilities for organisms (fish farm, fish preserve, aquarium,
etc.) There is a possibility of extinction of organisms caused by leak current or by
leakage of enclosed liquid from mechanical seal.
Do not use the pump at an important facility (computer cooling apparatus, cooling
apparatus for refrigerator, etc.)
Since machining oil, rubber-releasing agent, and foreign matter, used in pump-
production line, enter the handling liquid, operation of the pump shall be done
after fully flushing the pump to confirm the absence of foreign matter, depending
on the facility.
Limit the handling liquid to water. Do not handle oil, seawater, organic solvent,
etc., other than water. These liquids cause trouble of pump to result in electric
leak and electric shock.
The pump is a submersible sewage pump. Do not operate the pump for a long
period of time or under vigorous startup-shutdown conditions. Such operations
may lead to liquid leak from mechanical seal to induce trouble of the pump within
a short period of operation.
Install a stand-by pump preparing for an accidentally stop of the operating pump.
There is a possibility of suspension of water supply to stop the facilities.
