Decent Lab pump with way better pressure than a centripital

Comments about None 120000/PQ-12DC Miniature Gear Pump, 0.67 GPM (2520 mL/min), 12 VDC Lab Model:

My pumps been working for maybe 80 hrs of operation over the course of a year of research.

I am using the pump with PWM through an N-channel MOSFET on the ground with a fly-back diode and clamping zener diode.

I also strapped a fan on the backside of the motor for cooling and even at 100% it's cool to the touch.

When running below 80% is't not too noisy.

The ground connections seem to be getting a little flaky lately or maybe it's my driving circuit.

We have used two of these pumps. Both broke within 30 minutes of use within the design specs. It cannot be overstated how terrible these pumps are.

Pros

  • Audible Speed Monitoring
  • Pumped 2520 Ml

Cons

  • Breaks Easily

Best Uses

  • Welding Plastic

Comments about None 120000/PQ-12DC Miniature Gear Pump, 0.67 GPM (2520 mL/min), 12 VDC Lab Model:

This pump successfully pumped 2520 mL, as advertised. It appears that its mislabeled though, as it only did that one time, not once every minute. Perhaps the spec means 1 minute duty cycle, then disassemble and re-machine the gears that have welded together?

The pump is acoustically satisfying. We were using it in a system with a 1/3hp motor, some 1/6hp centrifugal pumps, a 2kW gas-fired boiler, and a small vacuum pump. This pump comfortably drowned out all their other annoying noises with a nice E flat above middle C. In the 3 minutes that it ran, that tone rose about half an octave at a soothing rate. I presume this feature is so that you can track the motor speed without annoying interfaces like signal wiring.

This pump is also much easier to debug than other pumps. I recently had to re-test a pump curve for another pump in our system which was very annoying. This one is very straightforward- 0 bar/0mL/min! Easy peasy.

My biggest concern is that visual appeal. Now that its a paperweight, it is only the third nicest looking one I own, after a leaky heat exchanger and a flow meter with a stuck float. So it probably won't get used much that way.

        Comments about None 120000/PQ-12DC Miniature Gear Pump, 0.67 GPM (2520 mL/min), 12 VDC Lab Model:

        I am using it to circulate hot water in home.
        Connected with PEX tubing that fits the barb fitting and standard 3/8 compression fitting.

        It has stalled, jammed, or failed to start pumping at 6volts but seems very reliable to start at 8 volts and up. The motor got very hot when it stalled, but fortunately did not burn out. It seems to be built very robust.

        Impressed with the pressure output and inlet draw.

        The only negative is the noise level.
        Have not measured the decibels, but an irritating rather loud hum at the speed I chose to run it.

        Good value, well performing and satisfied purchase.

          I use the product for an anaerobic bioreactor. The pump works great, and is incredibly durable. The pump can be connected to a variable power supply and control the flow rate.

            Does it come with a controller to vary the voltage to the pump. If not what would you recommend?

              A:

              This unit does not come with a controller to vary voltage to the pump. If you are looking to supply the pump with DC power you can utilize item 26849-80. If you are looking to supply the pump with variable AC power you can utilize item 00248-PK. Please contact our technical support department if you have any other questions on this item.

          • Q:

            I recently asked "If all the other specs are met, is this pump suitable to pump liquid at -30°C (motor at room temperature)?" and got the response "The wetted parts cannot go down that low of a temperature." and couldn't find a way to ask a followup question so I am submitting this follow up. It seems like the only part that is even close to its temperature limit is the Buna-n. Buna-n is typically used as an o-ring. Is it possible to replace this o-ring with another material? Or is the problem not a fundamental material limit?

              The max pressure this will output is 21psi. There are too many factors involved to predict what the pressure would be, but it would have to be less than the 21psi.
