Kamoer lab WiFi UIP Stepper Motor Intelligent peristaltic Pump high Flow Rate dosing Pump (3 rotors, 1-1520ml/min, 110V-220V AC, Foot Switch Support, Touch Screen Display, White)

I required precise (+/- 1%) metered volumes of Cyclohexane CAS # 110-82-7.I selected the Kamoer Lab UIP Stepper Motor Peristaltic Pump P/N Lab UIP CK15-3-S18 (listed at $599.00) after viewing the introduction video (English version).The unit arrived in a timely manner from the manufacturer in China. The unit was supplied with a length of silicone tubing 7.9mm ID x 11.1mm OD. Cyclohexane is not compatible with silicone. I purchased Viton® Fluoroelastomer tubing (soft, 60A durometer) 5/16” ID x 7/16” OD. Viton® tubing is rated as “excellent” for use with Cyclohexane.The unit has at least two listed options offered, Temperature Sensor for Lab UIP, Kamoer P/N CT-2, and Liquid Sensor for Lab UIP, Kamoer P/N “Lab UIP liquid sensor” UNSPSC Code 41105100, both of which at the time of this product review are listed as “currently unavailable” on Amazon.The unit arrived in four work days after purchase. Upon receipt of the unit I inspected the unit for transit damage, of which there was “none”. The unit had been well packaged to ensure the integrity of the unit during transit. I reviewed the manufacturer’s instruction manual. As of the time of this review the manufacturer does not have an English version of the manual available for download from their web site. If there is an English version available on the web site, I was unable to locate it. An English version of the User Manual “is” included with the unit. Hopefully the manufacturer will take note of this product review and make an English language version of the User/Instruction manual available for download from their web site in the near future. The English language User Manual that arrived with the unit is of very high-quality workmanship and presentation.I found the pictorial layout and well-defined instructions exceptionally useful in progressing through the setup and first tube calibration. The touch-screen user interface is clear and well defined. One of the reasons I selected this model and manufacturer is because of the touch-screen user interface.As of this review I have had the unit a little more than 24-hours, and it is functioning as advertised. I am very much impressed with the accuracy and ease of use of this unit. A five-star review is justified and warranted in my opinion after evaluating the physical integrity, the software, user interface, and accuracy. of the product. Very well-done Kamoer!

the pump head plastic quality is really bad, it breaks after few time use.

While the pump performs great as far as pumping goes there are some software and documentation issues that leave it lacking. If the unit loses power briefly it does not resume operations but stops and returns to the main menu. Could be devastating. Should have an option to resume on power up.There is no information included regarding the RS485 and CAN interfaces. What is the protocol to use on these ports? What is the pinout of the connector? If using the WIFI app disconnecting causes the pump to stop doing what it was doing. You should be able to connect to the pump with the app, configure it, start process and disconnect app. Would be far better to be able to connect remotely via internet and configure/monitor pump using MQTT etc. Little value in a phone app that only provides local connection. Was not able to locate a manual online. They have a web page entitled Technical Library but it only contains general tips and not specific instructions on operation.No information about firmware upgrade potential. Is there a way to update the pump remotely? Perhaps they should open source their firmware so that others could add that functionality.EDIT: Discovered that the phone app help menu has a description of both the RS485 and CAN Protocols. A very odd place to keep the information. Why it is not in the manual is baffling. You cannot force it to remain in remote RS485/CAN mode so If power is lost the machine does not come back up in remote mode and requires that you reselect it from the front panel. Why could it not always be able to be remotely controlled? If valid data is received on port then act on it.

Using it for a small assembly line - it has dosed 21.5ml of liquid ammonia over 8,000 times with no performance decrease, and still pumping +/-0.75ml on the dose size.We used our own one-way nozzle to reduce drips and air bubbles entering the line after the pump stopped, I believe this is what led to our repeatable accurate doses.
