Stainless Diaphragm Pump MAINTENANCE

• Refer to the part views in the assembly chart for the parts’ number and name to understand the information of the part and service kits.
• Parts which marked with “Vulnerable parts”, to prepare these parts in hand will help you save time for fast maintenance and reduce downtime.
• Maintenance service kits’ functions are separated into 2 independent sections: 1, Air kits; 2, Wet kits. Wet kits will be further subdivided to match the material options for typical parts.
  • Provide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service disassembly and reassembly.
  • Keep good records of service activity and include pump in preventive maintenance program.
  • Before disassembling, empty captured material in the outlet manifold by turning the pump upside down to drain material from the pump

Troubleshooting guidance

1.Air outlet has fluid when pumping

Check if the diaphragm be damaged

Check if the diaphragm bolts loosening

2.The output fluid has bubble

Check the suction pipe joints are well sealed

Check the suction pipe and fluid inlet are well sealed

Check the ring between fluid inlet and fluid cap are with O-ring

Check the diaphragm bolts are fastened

3.Pumping capacity is low

Check if the air supply is stable

Check whether the inlet and outlet is blocked

Check the joint to the fluid inlet is sealed and not leakage

Check if the ball stick to the ball seat or ball seat is not suitable

4. Without reciprocating motion, the air flow is discharged from the exhaust port

Check the sealed ring of the main air valve

Check the sealed ring of the pilot rod valve

Check the sealed ring of the diaphragm rod
