Rocking Piston Style and Thomas Wob-L® Piston Compressors.  

On this page you find the most of the rocking piston pumps we carry.  We carry lots of brands from Thomas / Gardner Denver, Gast, GSE International, EasyPro, Kasco Teich Aire, and many more.  If you do not see one you need just ask!

Piston pumps can provide higher pressure and flow capabilities than many other pump technologies, in a much smaller package. They cover a wide range of applications due to the breadth of product platforms and performance capability.  In most cases these can be used as a compressor or vacuum pump for maximum flexibility and their quiet operation makes them ideal for noise sensitive environments like medical, Air Vending, Pond Aeration, Telephone Cable Drying, Wave Guide Pressurization, Mobile Dental Stations, dental and laboratory applications as well as hundreds of industrial applications. In addition, this pumps rugged motor shell and simple field serviceability extends the life of the product and maximizes uptime.  

Pictures are for representation only - actual items may vary in shape, style, size, color, etc.
Unless otherwise stated these come ready to hard wire into a junction box, attach a plug to, or splice onto a power cord.  Easily accomplished common hand tools.  In most cases Brown is Hot, Blue is Neutral, and Green is Ground.  These will come with an intake muffler, capacitor, and fan guards unless otherwise stated.  ALL NEW pumps will come with a 1 year warranty.

THE AC PISTON SERIES AIR PUMPS FOR AQUATIC AND HYDROPONIC APPLICATIONS
The AC piston range of air compressors is suitable for applications where high pressure is required to provide a continuous supply of oil-free air. Used in conjunction with air stones or diffusers, they are suitable for the aeration of larger hydroponic growing systems or aquatic tanks. 

The AC series pumps are an ideal pump for hydroponic and aquatic systems; although small in size its exceptionally large airflow allows the running of several applications. Designed with a finned aluminum casing, the AC series dissipates heat for cool running, making it virtually maintenance free.
