Warning
Caution
Note
1. Daily inspection
(1) As abnormalities with pressure, current, capacity, vibration, sound, etc. are signs of a failure,
it is important to refer to
reason, please keep an operations log.
Note
(2) The bearing allowable temperature is 110℃ or below. For sealed ball bearing types, refer to
paragraph4.Consumable parts. Expendables in this chapter.
(3) It is necessary to remove coupling guard from pump In order to be sure the water leaks from
shaft seal.
(4) Shaft seal is a mechanical seal, therefore there is almost no leakage when it is operating
normally. Even when a little leak is accepted at the time of an operation start, if operation is
kept for a while in the state, a leak will decrease. When a leak still does not stop, please stop
operation and check.
Do not touch the rotating parts such as the spindle, shaft
couplings, V-pulleys, etc. while the pump is running. Since
these parts rotate at high speed, doing so could result in injury.
Disassembly and repair of the pump should only be performed
by specialist maintenance technicians.
personnel could result in electric shock, and the pump catching
fire or operating abnormally and causing injury.
Always turn the power switch OFF before inspecting or
repairing the pump. Not doing so could result in the pump
starting up suddenly in auto operation, exposing personnel to
danger.
If there is a power failure, turn the power switch off.
Otherwise, the pump may start-up suddenly when the power
supply is resumed, exposing personnel to danger.
Do not touch the pump when the liquid handled is hot water.
Burns may result from high temperatures.
Do not touch the motor. The motor's surfaces will be hot, and
you could get burned if you touch them.
To prevent an accident if the pump stops running or an
abnormality occurs, immediately turn off the power switch.
Contact the shop from where you ordered the pump, or EBARA
to perform an inspection and maintenance on the pump.
When the pump is out of use for prolonged periods such as the
wintertime, water inside the pump could freeze, causing
damage to the pump. Accordingly, in such situations, either
drain all water from the pump or provide thermal insulation to
prevent the water from freezing.
Please put repair painting into effect in a period according to the use
environment. A screw department, the processing department which
applied rust killer and a corrosion prevention painting department are the
use environment of high humidity dew condensation and sometimes
generate rust.
