5
(6) Start of the pump
Do not dry running definitely.
The bearing of the impeller and the shaft are burned and the molded thermoplastic resin parts are
melted. It could cause liquid leaks or failure.
(7) The pump operation
Do not start and stop the pump at short intervals such as the intermittent operation. It is designed for
the continuous operation.
Under the intermittent operation, liquid leaks from the parts’ connection or fatigue breakdown could
happen for fluctuation load. Furthermore, do not open and close the discharge valve at intervals of a
few seconds during the continuous operation.
(8) Disposing of scrapped pump
When disposing the scrapped pump, thoroughly wash any liquid off the pump and discard it as
industrial waste according to the law.
(9) Leak protection
Always take appropriate preventative measure to safeguard against liquid leaks in the event of a
breakdown of the pump or piping.
(10) The used liquid
Specially, when using the pump in the hazardous liquid such as cyanogen, it sure appropriate
preventative measure is taken to safeguard against liquid leaks.
Equip the liquid level control device for the unexpected accident. When decreasing the liquid level, it
makes the motor stop at the same time as the alarm rang. Additionally, install the device which opens
the valves fully.
The impeller is contained the magnet and could become worn or damaged when using the liquid with
iron powder or slurry.
The limit of the used liquid:
Temperature: 40 degrees or less (104F)
Viscosity: 30MPa. s or less (at 20 degrees (68F), S.G.1.0)
(11) Dismantling of the pump
Do not dismantle the motor including the cable. The use after the pump is assembled or
disassembled by customer self is out of our responsibility.
When overhaul of the motor, contact the distributor or us.
