What the pump listings tell you
We compared 5 pump listings. Flow rates run from 95GPH to 800GPH on the submersible pumps, with the diaphragm and transfer pumps stating 1300ml/min and 2LPM. Stated lift heights run from 3.0 ft to 10 ft, with 2 listings giving no lift figure. Power runs from 5W to 60W on the mains pumps, plus a 12V DC diaphragm pump. Only the DOKO names a protection feature, and none state a warranty term.
Buying guide: best water pump for co2 laser under 50
Flow rate and lift height
These are the 2 numbers that decide whether a pump fits a cooling loop. The submersible pumps state 95GPH, 210GPH and 800GPH; the uxcell diaphragm pump states 1300ml/min and the ONESAM transfer pump states 2LPM. Lift heights are 3.0 ft, 3.3 ft and 10 ft on the 3 submersibles; the other 2 listings give no lift figure. Compare like with like: GPH against GPH, and do not convert between units the listing does not use.
Submersible vs diaphragm
The PULACO, VIVOSUN and DOKO are submersible pumps that sit in the reservoir, a bucket or a chiller tank. The uxcell is a self-priming diaphragm pump on 12V DC, and the ONESAM is a self-priming transfer pump with its own hose kit. A submersible pump needs the reservoir; a self-priming pump can pull from one. If you are choosing between a pump in a bucket and a dedicated chiller, see our water chiller vs submersible pump comparison.
Power and noise
The mains pumps draw 5W, 8W and 60W at 110 to 120V; the uxcell draws under 300mA at DC 12V and states 65dB. The PULACO, VIVOSUN and DOKO all claim quiet operation without a stated figure, so treat that as the maker’s claim. The ONESAM ships a 110 to 240V supply with adjustable speed.
Fittings and what is in the box
Check the hose sizes before anything else. The PULACO includes 3.3 ft of tubing with a 0.3 in nozzle and 3 suction cups; the VIVOSUN includes 2 nozzles, 4 suction cups and a 5 ft cord; the DOKO includes 3 outlet adapters, 4 suction cups and a 6 ft cord; the uxcell has a 4mm (0.16 in) water hole; the ONESAM kit includes a 6.5 ft food-grade hose with 6mm inner and 9mm outer diameter, 2 clamps, 2 filters and a hook tube. For the full-size sibling guide, see our best water pump for CO2 laser picks.
Water and mains power mix badly. Keep the power supply and all connections dry, and plug mains pumps into a GFCI outlet. The uxcell runs on 12V DC; the PULACO, VIVOSUN and DOKO list 110 to 120V, and the ONESAM ships a 110 to 240V supply.
Project Match
- Aquarium and tabletop fountain: the PULACO 95GPH lists aquariums and fountains; the VIVOSUN 210GPH 2-pack lists ponds, fountains and hydroponics.
- Pond and waterfall: the DOKO 800GPH with 10 ft lift, 3 outlet adapters and adjustable flow.
- Homebrew, water changes and liquid transfer: the ONESAM 2LPM food-grade kit with hose, clamps and filters.
- Coffee machine and water dispenser: the uxcell 12V diaphragm pump at 1300ml/min.
- Laser water cooling: the ONESAM listing names water cooling among its uses; for the others, match the stated flow and fittings to the cooling setup.
How the scores add up
Each pump is scored out of 10 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. Safety points go to named protection features: the DOKO names a 176°F auto shutoff, and none of the other listings name a safety feature, so they score zero on safety. No listing states a warranty term.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: lasers and CNC
Can I use an aquarium pump to cool a CO2 laser?
Makers do it with submersible pumps in a bucket loop, and the listings here sell these pumps for aquariums, fountains, ponds and hydroponics, with the ONESAM naming water cooling as a use. Match the pump’s stated flow and fittings to what the laser maker specifies for cooling.
What flow rate does a cooling pump need?
It depends on the loop. These listings state 95GPH to 800GPH, 1300ml/min and 2LPM. Check the laser maker’s cooling guidance and choose a pump that states a flow figure in the same units.
Can these pumps run dry?
The uxcell and ONESAM are self-priming, while the PULACO, VIVOSUN and DOKO are submersible pumps made to sit in water. The DOKO adds a 176°F auto shutoff against overheating.
How loud are these pumps?
The uxcell states 65dB. The other 4 listings claim quiet operation without a stated figure.
