Misting Pump FAQ

Q1Why does my pump run in unwanted low pressure?
  • Clogged filter or improperly sized
  • Leaks from fittings or connections
  • Cracked or kinked hoses
  • Worn O-rings in safety regulators, check valves or relief valves
  • Severe cavitation, inadequate water supply, stressful inlet conditions
  • Worn nozzles/valves
  • Air leak in inlet plumbing
Q2Why is my pump unable to produce pressure?
  • Severe damaged seals
  • Cracked water inlet/hose
  • The motor does not work properly
  • Worn nozzles/valves
Q3Why does my pump fail to water suction?
  • Worn seals and valves
  • Clogged filter
Q4How does the unusual noise or vibration from my pump?
  • Bearings are damaged
  • Imbalance or inadequate installation in pump’s assembly or other components
Q5Why does the nozzles cannot produce the mist. Possible causes:
  • Clogged/worn nozzles
  • Clogged/ hoses
  • Air leak in the hoses or the pump
Q6Why does Oil or water leak
  • Severe cavitation of the seals
Q7Why does the motor stop running?
  • The power supply is not stable
  • The cable extension is too long to make a stable power supply
Q8Why does the loud knocking noise my pump
  • Worn bearing, connecting rod or crankshaft
  • Stressful inlet conditions
Q9When do I maintain my pump?

We suggest every 1200 hrs or 6 months to replace or refill the oil and check.
The seal kits can last for 3000 hrs. Valves kits are designed for 3000 hrs. durability.

Q10What oil should I use and how to change the oil
  • Prepare changing oil’s tools.
  • Loose oil pump pipe’s screw with 8mm fixed spanner and pull out oil pipe.
  • Use 17mm fixed spanner to take off oil pump assembly.
  • After oil leaking finished, loose 3 M5 screws on front case, and take off the filter net, use air pressure gun to blow then wipe the front case.
  • Put back oil pump assembly and tighten with 17mm fixed spanner.
  • Put back the filter net to front case, lock up front case to its place. Oil pipe install back to oil pump assembly with 8mm fixed spanner tightened.
  • Fill 15W-40 hydraulic oil into oil cup with 50cc, after test running 5cc more, total needs 55cc.
Q11What is the pump normal working temperature?
  • The operation temp can be controlled around 25C or 77F as the bearing is lubricated by the self-lubricating system all the time without generating heat.
Q12Should I use an extra pulsation dampener?

Our pumps use inner pulsation dampener design. Basically, for small flow rate pump below 5 LPM, no requirement for an extra pulsation dampener. However, for some cases, this device is preferred to have.

  • For long distance delivery, the dampener can reduce the water hammer with long discharge line.
  • Requirement for stable and smooth liquid flow. e.g. membranes RO application
  • Protection for regulator, unloader.
