  • Working Pressure Range: -70KPA-220KPA
  • Vacuum: >350mmHg
  • Noise: 65dB
  • Working range: 9-15LPM
  • 500hr Lifespan

Vacuum Pump - 12V Product Help and Resources

IoT MOSFET Controlled Pump

We used this pump in a blog post on our web site. You can read about it here: Hardware Hump Day - Remote Smoke Machine Prank [ ]

Mounting the pump

Unfortunately, we do not have an exact part in our catalog to mount the vacuum pump. Maybe you can cut a hole in the enclosure that you are using and use some zip ties? Or maybe you can find a mounting clamp that fits around the diameter of the motor. Looking online, there is a 3D model of a clamp that can be printed with a 3D printer [bracket - ].

Otherwise, the closest mounts in our storefront are the 37mm diameter motor mounts [ like Motor Mount Clamping - and Motor Mount - Swivel Clamp - ]. The clamps were designed to be used with the Actobotics gearmotors. Testing out the swivel clamp on the vacuum pump's motor, it was a little loose since the diameter was about 36.65mm. I had to switch the set screw to a smaller length to secure the motor to the clamp. Maybe you can add some material between the vacuum pump and the clamp for a better fit.

Gripper tutorial

Besides our tutorial that is on our site, you can look at this video tutorial online “DIY Robotic Gripper: Give Yourself A Hand ” - [ ] .

Power requirements

The best to power these would be to provide a power supply with about 12V with a minimum current around 0.40A. It pulls a maximum of 0.54A from a 12V variable power supply. If you adjust the voltage or current, the vacuum will provide less suction just like any dc motor. If you apply too low a voltage, the motor will not start, or will stop if you blocked the vacuum pump's nozzle.

  • cypher543 / about 12 years ago / 3

    The original manufacturer of this pump (Ningbo Forever Electronic Appliance Co., Ltd.) lists the maximum continuous working time as 5 hours with a total lifetime of 500 hours on their page. They confirmed those values via email. So, I wouldn't recommend running this pump for long periods of time. In my case, I need something that will operate for a minimum of 12 hours a day.

  • Member #514643 / about 10 years ago / 2

    has anyone tried to PWM this guy? I am hoping for a fairly-constant vacuum/pressure level that is a bit less than what I'm getting from it... I can't seem to get it to turn on for a short (10mS) interval, either.

  • To answer a few questions about how well the pump sucks, I hooked it to a vacuum gauge. The gauge read 760 mmHg before I powered it up. After turning it on and letting it equilibrate, the gauge read 218 mmHg. Thanks very much to my bro Mike Stephenson for setting up and letting me use the gauge and LabVIEW program for reading the gauge.

    Transmorgrifying to other units, atmospheric pressure at that time was about 14.7 psi, and the pump made the pressure in the tube 4.2 psi. This is the thing I wanted to know, that there would be a 10 or so psi difference between atmospheric pressure and, for instance, the pressure in my coffegroundgrippermachine. I only have one of these vac pumps, so I could not perform any statistics, and I'll have to experiment anyway to figure out how to do stuff. In the words of the great philosopher Lemmy Kilmister "Take it or leave it."

    Your mileage, of course, may vary.

  • REDACTED-GDPR / about 13 years ago / 2

    Hey, could you expand on this more: '0-16" Hg vacuum range'
    I was looking at vacuum pump measurements and it seemed like this means that the 30" hg at atm could be brought down to a vacuum of 14" hg. But then I got into looking and there are micron measurements for vacuums of 500 microns. Instead of subtracting this distance from the 30" hg they added from 0". This leads me to my question of what the zero in the 0-16" inches because this would either mean that the vacuum is perfect or that the vacuum doesn't work at all, none of which really make sense.

    • Member #135449 / about 11 years ago / 2

      To you guys unsure of the pressure range... This is really a common sense kind of issue. Does it make sense that the pump would generate 0" of vacuum, i.e. a PERFECT vacuum? No, of course not. It's a $15 part for hobbyists. This means that it generates up to 16" of differential pressure, i.e. at 30" of mercury atmospheric pressure, it can bring that pressure down to ~14" or up to ~46".

    • It's a range. Does this help:

      • WimL / about 13 years ago / 5

        that doesn't help much, since that page also describes both systems of measurement! Does this pump produce a 16"Hg differential from atmospheric, or can it evacuate a chamber to 16"Hg absolute?

            • Doov / about 12 years ago / 1

              So to clarify - this is not actually a vacuum pump, correct? It's just a regular air pump? Also where is the 16"Hg coming from? On the data sheet I see -70 kPa, which is -20.67"Hg. I'm assuming that given the 250 kPa upper range this actually a positive displacement pump that's hooked up in reverse to create vacuum?

    I bought one of these, attached it to a 12 v 2.5 A transformer and get only the most modest suction- about enough to loosely hold onto a piece of paper if put over the inlet. Is the pump function as one would expect and if not, does anyone have an idea of why it might not be?

  • Dan_Linder / about 10 years ago / 1

    How well does this perform if we're only providing it 7.2V rather than the full 12V?

    • Dan_Linder / about 10 years ago / 1

      Following up on my earlier question, I ordered one and I am happy to say that it does run on 7.2V quite well. My students and I did some ad-hoc tests and it works well enough we're going to try to build a coffee grounds gripper next. (Spoiler: Thankfully the pump is a pretty simple design and quite easy to take apart and remove coffee grounds from....)

  • qzjake / about 10 years ago / 1

    How much does it weigh?

    Is that an inlet and an outlet on the pump? I'm trying to figure out how I might turn this is an actual, mini, floor vacuum.

    • Dan_Linder / about 10 years ago / 1

      I can tell you that it has the vacuum pressure, but not the total air flow necessary to really pick up much when used as a standard floor vacuum. If you had two flat surfaces, it could possibly be use in a pick-and-place machine, but not easily for ad-hoc picking up of small things.

    Hey, does anyone know can this be used to as a vacuum pick up for automatic pick and place..

    • Dan_Linder / about 10 years ago / 1

      My students and I were able to play with ours a bit yesterday. If the pieces you're looking to pick up and move are small/light and you have a small (say 1/8") tip on the pick-and-place wand it would probably work. The vacuum produced is pretty constant, but low flow of actual air. If you have a very compliant rubber tip that would seal air leakage you might get away with larger components.

  • Member #546360 / about 10 years ago / 1

    Has anyone used one of these in a portable project and can you recommend a good cheap battery supply which supplies the required 12V and 1A?

  • Member #564369 / about 10 years ago / 1

    Again like some other before I have the question if this can also be used as a normal air pump not vacuum? It's not clear at all because the spec sheet lists air pressure and vacuum as 2 distinct specs and also on other sites it is listed as an air pump??

  • Will this work as a pressure pump?

  • att: Joseph / about 10 years ago / 1

    I have some questions about this pump.

    Q1 Does it suck from the inlet and below out the outlet. I seems to indicate this in the spec sheet as there is a Vacuum parameter and a pressure parameter . Can anyone confirm?

    Q2 If i reverse the polarity of the vacuum motor will the inlet and outlet reverse also (ie suck and blow in the other direction) can anyone confirm?

    thanks in Advance : Joe

    • Dan_Linder / about 10 years ago / 1

      Just got ours and I can answer both: A1 - Yes, there is a small flow of air out of the outlet. I don't have a vacuum/pressure gauge to give more specifics.

      A2 - The motor is NOT polarity marked, and the design of the vacuum pump does not require the motor to run in a specific direction. No ability to reverse the inlet/outlet by simply reversing the wires.

  • Member #532278 / about 10 years ago / 1

    Hello, is this pump able to handle small amounts of liquid?

    • Dan_Linder / about 10 years ago / 2

      I wouldn't as it's not designed to do that. The portion of the pump hooked to the motor does not appear to be sealed sufficiently to keep water out of the motor.

      If by small ammounts, you mean just a couple drops during normal operation, then it might be possible. I would expect the droplet to follow the same path of least resistance and exit with the air. BUT as with any time you mix water and electricity, it's better to air on the side of caution. In this case, I'd suggest you put in some sort of canister or drying filter between the pump and the intake where it could pull in moisture.

  • Member #544783 / about 10 years ago / 1

    I wonder if i could I use this for vacuum filtration separating precipitate. Most minimalist vacuum filtration setups come with a cheap hand vacuum pump used for bleeding automotive brakes. A hand operated vacuum pump would work fine for filtering, but being able to keep a constant vacuum to help dry the precipitate is it's shortfall. Anyone else heard of using one of these 12V vac pumps for this purpose?

  • Member #540677 / about 10 years ago / 1

    Hello! I want to make a roomba like robot, and I wanted to now if some of you think this has the suction for this? Thanks

    • MikeGrusin / about 10 years ago / 2

      Sadly no. Floor vacuums need high volume / low suction. This pump is designed for low volume / high suction. It wouldn't move enough air to budge your dirt. But you might be able to adapt our blower, which moves a lot of air. It inhales through the body (think of a hair dryer) so you'd need to glue some sort of duct to the center of it to achieve suction. Good luck!

  • Member #519556 / about 10 years ago / 1

    I'm looking for a pump that can be switched from suck to blow with an electronic switch. Any suggestions? Thanks

    • Dan_Linder / about 10 years ago / 1

      This one will NOT work that way - the pump mechanism works in the same fashion regardless of motor rotation.

  • Member #416464 / about 11 years ago / 1

    Hi, I need help. Electrical noob here. Can this vacuum pump have varying levels of suction force by varying the voltage applied to it? Connection to an Arduino board and programming it? Would that work? Much thanks.

    • adamj537 / about 11 years ago / 1

      If you hook this pump to a sealed container, it will produce varying pressure by varying the time that voltage is applied to it. Placing too low (or too high) of a voltage on any motor, including a pump, may damage it.

      However, you can also hook this pump to a leaky container, and it will produce varying pressure by varying the speed of the pump's motor. You can use PWM (pulse-width modulation) of the voltage to change the pump's speed (an arduino has PWM libraries).

  • Sofia / about 12 years ago / 1

    Is this item arduino compatible, & if so how would I program it to keep a specific amount of pressure, like when I am wanting something to be vacuum pressurized.

    • adamj537 / about 11 years ago / 1

      You can power this pump (or any motor) with an arduino and a transistor or relay. Sparkfun's tutorials should cover that.

      If you hook this pump to a sealed container, it will produce varying pressure by varying the time that it is on. If you hook this pump to a leaky container, it will produce varying pressure by varying the speed of the pump's motor. Use pulse-width modulation to change the pump's speed. Do not use pulse-width modulation with a mechanical relay, or the relay will break.

      To regulate the pressure, use a pressure sensor to tell the arduino when to turn the pump on or off. If you want to be accurate, try to find a sealed container, and pressurize it using the "leaky" method. Use the "sealed" method to fill a balloon or in cases where the actual pressure really doesn't matter.

  • Philb / about 13 years ago / 1

    Had one of these turn up this week and I must say, if decibels were somehow related to Hg then this would be a winner. I reality they aren't. My DIY solder-sucker project sucks (and not in a good way)! Worth trying though, and learning by trial & error is not a vacuous thing...

  • Member #70600 / about 13 years ago / 1

    If reversed will it work (for blow)? Some vacuum pumps seize up if run backwards (veined). I'm looking to build a picker, and would need a 'blow off' to break vacuum, and would rather not get into solenoid valves and such.

    • Dan_Linder / about 10 years ago / 1

      This one will NOT work that way - the pump mechanism works in the same fashion regardless of motor rotation.

  • booma15 / about 13 years ago / 1

    Hey was just wondering if theres a way to make the vacuum to suck then blow without swapping the hose. Can it be done by just the programming? Im using the Audrino Uno processor if that helps. Im a newby to all this so simple instructions would help :)

    • Maybe use a motor driver... they are used to drive a motor forward and backwards :-)

      • GregFR / about 13 years ago / 1

        Hey Robert,
        I'm planning on using a motor driver, but do you know for sure that running the motor backwards will actually reverse the flow of the air? e.g. will the pump actually work with reversed current? Thanks.

    • Kshatrya / about 13 years ago /

      This is a diaphram pump, so reversing the motor won't reverse the airflow. I don't think reversing the motor to reverse the x-flow works on more than turbine or Tesla pumps.

  • franspaco / about 13 years ago / 1

    Can I use this as an air compressor for an RC submarine?

    • Promptcritical / about 13 years ago / 2

      Probably not. You could probably get a few psi out of it but I wouldn't bet on anything greater than about one atmos, or 14 psi max. You would need a huge air system to blow ballast tanks, which would in turn cause a bouncy problem.
      A better solution, which I've used was to take a used threaded co2 cartridge from a bike emergency pump, bore out the center of the threaded area and and tap it so you can put a valve in it. Then you can pressurize it with an air compressor, and use it in your air system. An added bonus is that when you have three or four it looks like the HP air system on a sub. You can use 1/4" stainless as the air header.

      both of those will have tube in tube out

      • intranick / about 13 years ago / 1

Great Pump

Using the pump for a personal project and it definitely serves its function. Not a lot of quality 12V pumps out there like this one.

Works but need more vacuum

The pump works well, but for our lab use, it needs to generate more vacuum. The spec states 16"Hg, thought it would work with the vacuum cup grippers used in the robotics lab, but running through the lines and valve, creates just enough vacuum to pick objects up, but drops easily with just movement.

It works, but we have to really plan accordingly to make it function.

Compact and Efficient

I received the vacuum pump within a few days and it was in an appropriate package. It started right up; works fine with chemical filtering setup of mine. Design could be improved by having small feet with holes so pump could be easily attached to a platform.

Because of the apparent quality of the pump. I'll be ordering other things from Sparkfun.

Entered the all school science fair!

My robotic gripper worked really well! As soon as my science teacher saw it she said you are entering the science fair!

Great little vacuum

I used it to filter wine and degas my fermented wine kit. Creates plenty of vacuum to draw my wine from the fermentation container, through a 22cm double plate filter #2 into a clean carboy. Presto job done. I powered the pump with a 12 volt 2amp battery trickle charger.

No good for solder sucker

Not enough vacuum for sucking solder but probably has other uses. I still gave it 3 stars since it does suck, just not enough for my project.

Good little pump

works great for small projects.

Well... Actually... it really sucks!

It does exactly what I was hoping it would do. Measured about 1/2 of an atmosphere on the vacuum gauge.

Excellent mini pump


Strong and useful for vacuum and little pressure

I have not been able to wire it up yet, but I hope to use it to suck out the power steering fluid from the reservoir on our car and re-fill with new oil..

Reviewing Vacuum Pump - 12V

It is working very nicely. I am much satisfied with this product. Masroor

Works well

I bought it to make a gripper and it works very well for that as long as there is enough juice and the tubing is fairly short (the longer the tubing, the more airspace has to be cleared so the slower it grips.) It would be helpful if the inlets and poles were marked.


This tiny pump is "amazing", performed beyond my expectation.....worth the investment, so "buy" it. Thank you

Works well for my needs.

This pump is small, but powerful enough to do what I need.

Just perfect!

It really sucks! :)


I am using this on my truck. It is taking the place of the truck's vacuum for my 4x4. Works better than I thought it would. I got a second one, just in case I needed it. So far, the one is working great

Works great

As advertised.
