It's a beauty folks. These are pretty clean take-outs from what we have been told is a breast pump assemply. They operate from 3VDC up to 12VDC, but that won't matter because we are going to include the wall adapter. (9VDC@2Amps) The steel housing measures 3.5" x 4" x 5" and inside is a gear motor, 2.5" piston style assembly and a control board. The controller has a speed control and a push button pause. The diaphram on the top of the assembly measures 2-3/4" and raises up and down about 1". It's a very soothng sound. Built in switzerland so you know is a sound unit. 

Nifty device that takes maxi air and squeezes it down into a mini condition. The device is roughly 6-1/2"" long x 6" tall x 4" wide. It has a 10 ft. cord that plugs into an auto lighter socket: i.e. it runs on 12VDC @ 10 amps. Air output is via a 12" hose with a variety of valve adapters for tires, soccer balls, rubber rafts and the like. Complete with a 0-250 psi gauge. Which should be plenty of pressure to explode a weak bike tire or flimsy beach ball, so please be careful!

This 20 GPM (gallons per minute) submersible fluid pump will shoot fluid approx (15) feet upward. Fits standard garden hose, Comes with (4) rubber feet and It even includes a brass barbed hose connector for 8mm hoses etc. Unit measures 7" x 5-1/4" x 4" with a 3” handle and a 15-foot power cord. It has a lifting handle on the top and a removable filter space for cleaning. It does not include a filter. Pump must be submerged 2x the pump height (aprox 13”). Operates on 120 volts at 105 watts.

Jarvis Says: Catalog mistakenly mentions tubing is included. Tubing is not included. Do not run pump dry.

Got lots of aquariums? This oil-free Hailea 115V air pump is strong enough to keep air flowing into your large or multiple aquariums, and its linear piston design ensures long life. It’s low-noise at <60dB (The manufacturer says low-noise, but trust us, you don't want this running in the bedroom.) and low-vibration, because fishes (and you) don’t go for those things. Draws 160W of power and puts out a continuous 5 cfm of free-flow air pressure (that’s 145 liters a minute) at 5 psi. Has an inlet port with a 0.571 OD barb for 13mm tubing, and a 0.466 OD barb for 10mm tubing; and an outlet port for M12 x 1.5 metric pipe. Unit measures approx 11-1/4” x 6-1/2” x 5” with finned aluminum heat-sink housing and rubber-cushion feet. Weighs 13 lbs.

Here are the ins and outs of submersible pumps for your DIY fountain.These small electric pumps run on 24 VAC (For low energy consumption.) from the included wall outlet adapter, are rated for continuous duty, have (3) suction-cup feet, an adjustable flow control and both a straight and 90° 5/16" tubing adapter. This little pump is roughly 2-5/8" x 1.5" x 2-1/4", has a 6-ft power cord with an in-line switch, and pumps 70 gal/hr @ 1 ft lift. Plug it in and go with the flow. Indoor use only.

From Koge Micro Pump Co. (company motto: Let’s PUMP the World!), this nice little diaphragm air pump draws approx 400mA at 12VDC and will put out 3 liters a minute with a minimum pressure of 400mm/Hg. Measures 2-3/4” long x 1-1/4” square with 1/4” long x 5/32” dia inlet, and outlet barbs. Part #KPM32E.

This vacuum pump from Koge Electronics draws 100-250mA at 4.8V and is rated for >2.6L/minimum output and -460mbar of pressure. Measures 2-9/16" x 1-3/16" x 1-5/16" with a 3/16" OD x 3/8" inlet barb and a 3/16" OD x 1/2" tall outlet barb, plus (4) 1/8” ID mounting wings. Power terminals are exposed and you may get short leads. Koge model #KPV276.

This silver 9VDC air pump with a clear pumping assembly is 3-1/2" x 2” x 3” with a piston behind the clear plastic on one end. Both the 7/16” intake and ¼” output are on one side of the assembly. We couldn't find exact info on it, but it moves air at a moderate rate. Two 3/16” spade terminals on it’s motor side and will work for a short time on a 9 volt battery.

We’re guessing it’s from a medical device, but we know for sure that it’s a pump assembly from The Lee Company of Connecticut. Looks expensive, like it should cost more than ten times our price, and that’s why you shop here. Has a 2-phase (275mA/PH) 4.4VDC stepper motor, a Honeywell microswitch home sensor and a secondary pressure sensor leading to a 3/32” outlet barb. Has 250uL volume and measures 5-3/8” x 1-1/2” dia with separate wiring to the sensors and motor. Item# LPVX0517.
