12v DC Large Flow Dosing Pump Peristaltic Pump Upgrade 304 Stainless Steel Roller for Vacuum Aquarium Lab Analytical

I purchased this pump to do automatic water changes on a saltwater tank, with the water reservoir located in the basement.The pump does make some noise (probably wouldn't want it in a living area) but it has worked well so far. Peristaltic pumps all tend to be noisy but this one's a tad louder than lower flow ones I've used in the past.This thing has a great flow rate for a peristaltic pump! The pump motor is pretty good sized and and head seems very sturdy. Other, less expensive peristaltic pumps I've used in the past have had a flimsier head that flexes/wobbles sightly as the rollers spin, but this one is rock solid. No longevity concerns.Highly recommended for those without noise concerns. I will update my review if I have any issues down the road.

wasn't a problem for me but might be for someone else - the rollers are plastic

Bought this as an ATO Pump for my aquarium. It is connected to a standard 12v power supply plugged into the ATO’s relay switch (Smart AWC/ATO). It is currently pumping water effectively 5’ down, 60’ under my house, then back up 5’.I imagine you can vary the ml’s but for my case that wasn’t really important. I would guess several hundred ml’s a minute based on comparing to my other dosing pumps (which do dose precise set amounts).Any dosing pump will be loud at this flow rate and this one is no exception. At full speed you wouldn’t want it in the same room or even room adjacent.The build quality makes the Neptune DOS pumps look like a joke. Very sturdy metal roller and heads would make this ideal for an automatic water changing system.

Bought to use for a Raspberry Pi controlled bartender. Uses 12v signal. Works well, at Max has around 8oz/30sec of flow. Tubing smells a bit weird but is easily replaceable with food grade tubing.

These pumps work fine, we use them for dosing in a hydroponic grow system. Accurate, quiet, and reliable.

Good quality, good flow =)

Bought this pump for my marine aquarium to pump salt water from the basement tanks to the 1st floor. I have to admit, I took a chance that this pump as economical as it was could do the job. I had 100 ft of 1/4” tubing and about 11-12 feet of head to overcome. It worked like a charm pumping at least 4-5 gallons/ hr and that wasn’t even on the highest setting (9 vdc with 12 being the max). Minor annoyances were that it came with hose barb fittings so I had to replace those to adapt to the 1/4” tubing and was not clear if it had a power source—it doesn’t. It does make noise but since it’s in the basement it’s not a problem. I’ve run it now for about 4 hours and everything seems fine. I’m happy with it and would recommend it for at least my application.

Pumps well
