Q: What are the inlet and outlet fittings?
A: We provide 3/4" fittings for 40PSI pumps and 3/8" fittings for 160PSI pumps.
Q: Is the pump very noisy?
A: It's not "very" noisy. But it does make noise.
Q: Is it a self-priming pump?
A: Yes, it comes with 9-16ft suction.
Q: What is the maximum temperature of liquid this pump can run?
A: 60℃ or 140℉
Q: Can the pump run dry?
A: It can run dry for a short time without any long-term damage to the pump or the machine. But running dry for over 30 minutes would cause pump head heating(No transfer fluid cools it). Although pump would shut down if motor temperature heats up over 280℉, the accessories can not bear it(Such as plastic C clip, pressure switch). WE DON'T RECOMMEND TO RUN PUMP DRY FOR A LONG TIME.
Q: I can't shut off my pump automatically. Why won't the pressure switch work?
A: Pump shuts off when water pressure builds up. Check your pipe and connector for any connect If there is no leak, then the pressure switch may be broken. Replace with a new one or contact customer service if you received a broken one.
Q: The pump failed after three months.
In your case, I think your pump failed after running for three months without leakage and operation. There are two cases in which the pump is not working.
The motor is still turning, and the vibration can be seen after electricity, but no water is pumped.
This situation is usually caused by long idle running. If your pump is running dry recently, please cut off the power supply, pour some water into the inlet and moisten diaphragm diaphragm, restarted it after ten minutes.
If you never did that, please check whether the water supply is sufficient, is there any impurity entering the pump or anywehre of pump body is damaged? Find out and contact us.
The pump has no response while connected to the power.
In this case, it may be that the motor is overheated. Check if the pump had frequently started & stopped or just had been working for a long time before failed. If it did, then the pump is determined to be overheated, and the motor will continue to work until the motor is cooled to the normal temperature(about 30mins later).
If it still can't work the next day(excluding motor overheating), check whether the switch of the pump is burned, whether the switch wiring is loose (open the top switch cover), whether the power cord is contacted well, and whether the pump wire is damaged.
If the above methods do not solve the problem, please give a detailed description of the usage
Q: Why is the pressure unstable? /My pump can't reach 120PSI?/Pump stops after a short time of working, restart later, and this circle continues
The only reason is - leakages
Here comes with working principle of this pump
The start and stop of the pump is controlled by the pressure switch which is installed at the top of the pump. Its default setting range is 40-120PSI, that means when the system pressure reaches 120PSI, the pump will stop working. And it will be restarted when the water pressure drops to 40PSI or less. The pressure testing device has been running all the time.
In addition, the pressure of the system is inversely proportional to the flow of the system. Only ZERO flow, the system pressure will reach the maximum! On the other hand, if the pressure does not reach the maximum, one of the reasons is that the system is leaking.
According to the mail, we infer your usage scenario:
1) You did not turn off all the valves.
Eg. Your system is working. One of these spray heads may be sprinkling
2) You did turn off all the valves, but the valve is not closed tightly, or the outlet pipe is not sealed, somewhere may has a leak.
Eg. The accessories to the pump are not connected tightly with the PTFE TAPE, the plastic pipes have cracks, etc.
Explanation: When the pressure reached 120PSI, the pump has stopped working, but the system is still losing pressure, the pressure gauge shows the pressure drop (The more leaking, the faster the drop). When the pressue reduced to 40PSI, pump restart to pressurize water back to 120PSI.
Solution: Check and seal all the joints, reduce the water consumption of the system, and prolong the working cycle of the pump.
In the short term, the restarting work is completely normal. But it is recommended not to exceed 20 minutes, otherwise the motor will be overheated and the service life of the parts of the product will be affected.
Q: The motor is running, but no self-priming?
A: Self-priming will not work if there is a leak. On the other hand, using your diaphragm pump over a long period of time will cause it to dry out. If the pump is dry, it will not work properly. Follow the steps below to trouble-shoot self-priming:
Check the ① ② ③ Possible leakage points.
Add water to inlet to wet the diaphragm. Wait 5 minutes and then put pump back to the original power supply, try to see if it works
Q: Pumps start and stop frequently?
A: Definitely because of the leak, the pressure drops so the pump re-works. The leakage is much smaller than the pump flow, so the pressure reaches up to switch stop setting pressure then stops working. Look for leaks in your diaphragm pump per the instruction manual. Replace broken or worn out hoses, or wrap connectors with PTFE Tape. If your diaphragm pump is brand new and leaking, please contact customer service.
All About Switch
The use of switch accessories can make using the pump easier and more efficient. On-demand opening and closing can save a lot of manpower and electric resources.
If the switch function fails after prolonged use, check the wire. You may need to replace the switch components.
If switch pressure is inaccurate or needs to be adjusted, the specific operations are detailed in these photos:
1) How to adjust switch pressure setting
2) Switch can't stop the pump automatically
Pump shuts off when water pressure builds up. Check your pipe and connector for any connect If there is no leak, then the pressure switch may be broken. Replace with a new one or contact customer service if you received a broken one.
3) Pump runs and stops frequently
Definitely because of the leak, the pressure drops so the pump re-works. The leakage is much smaller than the pump flow, so the pressure reaches up to switch stop setting pressure then stops working. Look for leaks in your diaphragm pump per the instruction manual. Replace broken or worn out hoses, or wrap connectors with PTFE Tape. If your diaphragm pump is brand new and leaking, please contact customer service.

Stability of Different Media
Note: The diaphragm pump will be updated according to market demand. For the specific size of each model, refer to the page description in the product manual
The material of the diaphragm pump determines the stability of the pump as it performs with different tools and products. BACOENG diaphragm pumps are made of chemigum material. Chemigum performs much better than other diaphragm material, and helps maintain the life of your pump.
Stability is measured on a scale of A-C, with A6 having the highest stability and C1 as the worst. BACOENG does not recommend using a B/C level Pump. If you have to transfer to a B/C level pump, we recommend rinsing the diaphragm every time in order to prevent corrosion.
If you are experiencing problems with your diaphragm pump or any of its materials, feel free to fill out our customer service questionnaire or contact customer service directly.

I have two large polytunnel greenhouses and I saw online videos about people who had used small pumps like this to create an overhead spray irrigation system fed from rainwater collected in sumps, tanks or water butts. I wanted to use spray rather than ground watering as this can also help to keep temperatures down during the hottest parts of the year.
Building up the network of pipes and spray nozzles was pretty straight forward, but my first attempt failed because the nozzles I had bought need a higher pressure to force water through in a fine mist. The pump I originally bought just didn’t have enough power. Most of the diaphragm pumps I could find maxed out at about 60 or 70PSI and water was just dripping from my system, not spraying. I found this high-pressure AC powered pump that says it can deliver up to 160psi and up to 80 gallons per hour and it works brilliantly with my setup - I now get a really fine mist throughout the whole greenhouse which is perfect for the cooling that I wanted.
This pump seems to be designed for long running because it has a built in thermal protection system - the pump runs continuously for up to about 1.5 hours and it then automatically stop for a 20 minute cool down. It then repeats the process for as long it needs to run, protecting itself from overheating and this should mean it lasts for a long time.
One thing I really like about this pump is that it works automatically because it has an built-in pressure switch. The pump detects when you turn the feed tap from the water supply off and it stops running. The manufacturer instructions say that the pump is self-priming up to 6ft and that it’s absolutely fine to run dry. This was something I was worried about in case it emptied my rainwater sump and then kept going. This pump won’t get any damage if it does lose water supply and there’s a delay before the automatic pressure switch kicks in.
The other thing I like about it is the amount of noise it makes, or I should say the amount of noise it doesn’t make! I was worried that being an AC powered diaphragm pump it would make quite a noise, especially as it’s rated to high pressures, but I was really surprised by how quiet it was. It was no noisier than the smaller, low pressure pump I tried.
I’ve had this installed now for about a year and it’s been running problem-free. I’ve since added another valve after the pump which means I can now use it to fill buckets or watering cans from my rainwater sump just by turning the valve to direct the water into a hose and not up to the irrigation misters. Because of the power I was also able to attach a 30ft hose to it in order to use rainwater to mix up some concrete I was using to repair some paving in the yard. If you need a powerful pump and you’ve got an AC supply then so far I can recommend this one as doing a good job.
