INTLLAB 12V DC DIY Peristaltic Liquid Pump Dosing Pump for Aquarium Lab Analytical 3mm ID x 5mm OD

Good quality, great price.

I use a Jebao dosing pump for my aquarium. One of the heads stopped working so I bought this as a replacement. Super easy swap. The only thing I had to do was solder the power wires from the old jebao head on to the new power spades.

Quisiera que tuviera menos presión para regular niveles más bajos pero igual me sirvió perfectamenteLo que es un poco complicado es encontrar mangueras

I wanted to get a cheap peristaltic pump, which can pump water with flow rates 0.1 to 5 ml/min. The minimum flow rate of the INTLLAB Peristaltic Liquid Pump with 2mm ID x 4mm OD is too high for my purpose, so I have tried to decrease it by (1) using tubings with smaller ID, and (2) supplying the pump with lower voltage.Hooshing Silicone Tubing 1mm ID x 3mm OD (ASIN: B08QFFLP3S) were fitted into the pump head without problems but would easily slide out upon running because the OD is too small. I used MettleAir 129PP-1 Polypropylene Plastic 1/16" ID Hose Barb Union (ASIN: B00S529L6Y) to keep the tubing in place, and it works just great as if it was intentionally designed for this unit.Also, I replaced the original power supply (outputs fixed 12 VDC) with SHNITPWR 24W AC Adapter 3V~12V 2A Universal Power Adapter (ASIN: B08YN79VVD). At lowest voltage input, 3V, the pump starts to operate when the flow control knob reaches the middle of its range, and at 4V it can move in the entire range of knob positions.With 1mm ID tubing and 4V input voltage, it was possible to get a sustained flow rate as low as ~ 0.4 ml/min.

This review based on build quality as I didn't have the chance to fully test this dosing pump on a long run.So far all what I can say this pump is built like the original Nokia 3310 lol. The casing is made from very high quality plastic and it doesn't feel cheap at all, I would say the case and the motor controller alone worth the money. The pump head and Probably the motor it self made from cheap material.I ran it for 1 hour to test, the dosing is consistent . I'll make another review after I try it on my calcium reactor.*******Updated. The peristaltic tube head is very poor quality, I end up modifying this dosing pump by replacing the whole pump with high end motor and peristaltic head. As I said previously the only good part about this pump is the housing and the chip. If you're into diy and willing to do some modification like me then yes the price is fare, otherwise save your money and get something ready out of the box.
