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.
