Maintenance
Check pressure, output, voltage, current and other specifications. Unusual readings may indicate.
Refer to Troubleshooting and correct as soon as possible.
Daily inspections
1.
(1) Check current and ammeter fluctuation daily. If ammeter fluctuation is great, even though
within the limits of pump rating, foreign matter may be clogging the pump. If the quantity of liquid
discharged falls suddenly, foreign matter may be blocking the suction inlet.
2. Regular inspections
(1) Monthly inspections
Measure the insulation resistance. The value should be more than
fall rapidly even with an initial indication of over 1M ohm, this nay be an indication of trouble and
repair work is required.
(2) Annual inspections
To prolong the service life of the mechanical seal by replacing the oil in the mechanical seal
chamber once a year. Water mixed the oil or cloudy textures are indications of a defective
mechanical seal requiring replacement. When replacing the oil, lay the pump on its side with filler
plug on top. Inject suitable amount turbine oil No.32 (ISO VG-32)
