Troubleshooting

This section describes troubleshooting, inspection, specification and dimensions.

 Points to be observed

Observe the following points during maintenance work.
• 

 

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 resistant gloves, a 

mask and a face shield during disassembly, assembly or maintenance work. The spe-

cific solution will dictate the degree of protection. Refer to MSDS precautions from the 

solution supplier.

•  Solution in the discharge line may be under pressure. Release the pressure from the 

discharge line before disconnecting plumbing or disassembly of the pump to avoid solu-

tion spray.

• 

 

Risk of electrical shock. Be sure to turn off power to stop the pump and related devices 

before service is performed.

Troubleshooting

First check the following points. If the following measures do not help remove problems, con-

tact your distributor.

States

Possible causes

Solutions

The pump does not 

run.

Faulty wiring

• 

 

Correct wiring and resume operation.

Power-supply voltage is too low.

• 

 

Observe the rated voltage of the pump.

Motor failure

• Check the motor. Replace as necessary.*

Liquid can not be 
pumped up.

Air ingress through a suction line.

• Reroute piping.

A failed O ring seal.

• Check O rings. Replace as necessary.*

Foreign matters are stuck in the flow 
path in the pump head or piping.

• 

 

Dismantle, inspect and clean the pump 
head or piping. Replace as necessary.*

Malfunction of an air-operated valve.

• 

 

Check the valve. Replace as necessary.

A check valve (pump head valve) is 
stuck on a valve seat.

• 

 

Dismantle, inspect and clean the valve. 
Replace as necessary.*

A flow rate fluctuates.

Foreign matters are stuck in a pipe 
line.

• 

 

Dismantle, inspect and clean the line. 
Replace as necessary.

Air stays in the pump head or in a pipe 
line.

• 

 

Expel air.

A check valve (pump head valve) is 
stuck on a valve seat.

• 

 

Dismantle, inspect and clean the valve. 
Replace as necessary.*

A failed O ring seal.

• Check O rings. Replace as necessary.*

A hydraulic fluid leak

• Check for a leak. Replace as necessary.*

Motor failure

• Check the motor. Replace as necessary.*

Sensor signal is not 
outputted.

Faulty wiring

• 

 

Correct wiring and resume operation.

Sensor failure

• 

 

Check a sensor. Replace as necessary.*

Solutions marked with * are conducted by us.
