Maintenance
This section describes troubleshooting, inspection, wear part
replacement, exploded views and specifications.
Important
• Follow instructions in this manual for replacement of wear parts. Do not
disassemble the pump beyond the extent of the instructions.
• Always wear protective clothing such as an eye protection, chemical re-
sistant gloves, a mask and a face shield during disassembly, assembly or
maintenance work. The specific solution will dictate the degree of protec-
tion. Refer to MSDS precautions from the solution supplier.
• Risk of electrical shock. Be sure to turn off power to stop the pump and
related devices before service is performed.
Before unplugging the pump
Always stop the pump by key operation. And wait for three seconds before
unplugging the pump. Otherwise, the last key operation to stop the pump
may not be put in memory. In this case the pump unintentionally starts to
run as powered on, discharging liquid.
NOTE
• We do not assure material suitability in specified application and are not responsible
for any failure due to corrosion or erosion.
• Contact us or your nearest distributor for repair or contact a manufacturer of the host
machine which our product is built in.
• Be sure to drain chemicals and clean the inside of the pump before return so that a
harmful chemical does not spill out in transit.
