    Keg Party Pump Information

    Keg beer is best when dispensed cold. Maintain the keg’s temperature by using a keg jacket (KJ-01 or MM-PKJ). Or keep a keg on ice by placing it in a plastic tub (R4219) surrounded with ice. Keep the keg in a cool location out of the sun.

    Party Keg Pump INSTRUCTIONS

    1. Connect the party pump (tap the keg). Insert the coupler into the keg valve and depress the handle.
    2. Before pumping, open the faucet releasing natural keg pressure. First beers may consist of foam.
    3. Pour beer by squeezing the black faucet open completely. A partial opening of the faucet may create foam.
    4. Only pump to maintain a good beer flow. OVERPUMPING will create foam. Keep hose and faucet out of direct sunlight

    NOTE: If you have partially dispensed a keg using a party pump (air), you cannot use CO2 to finish dispensing it. When using a party pump, the keg must be finished the same day for the best flavor.

    Party Keg Pump Cleaning INSTRUCTIONS

    After each use, be sure to clean your party pump with chemicals specifically manufactured for beer line cleaning. The simple process takes only a few minutes and will assure trouble-free operation when the party pump will next be used. This is easily accomplished by the use of a pressurized cleaning bottle.

    Keg systems

    Not all brands of draft beer use the same type of valve in the keg. Each distinct "system" requires matching the appropriate keg coupler to the keg valve. In the U.S., there are eight different "systems" in use:

    D System –  The most common system available in the U.S., also known as American Sankey. Used by all the major breweries and many micro-breweries. Used by breweries such as Budweiser, Coors, Miller, Labatt, and Molson.

    S System –  Many European breweries use this system, also known as European Sankey. Distinguished by its longer, narrower probe than the D System. Used by breweries such as Heineken, Becks, and Amstel Light.

    A System – Commonly referred to as the German Slider because it slides onto the valve face. Used by breweries such as Spaten, Warsteiner, and Paulaner.

    M System – Introduced to the U.S. market. The body is the same as the German Slider, but the probe configuration is unique. Used by breweries such as Schneider, Aventinus, and Einbecker.

    G System – This system gets its name from the English developer, Grundy. The valve face can be thought of as a circle with three sides cut off. Used by breweries such as Bass, Boddington's,  Caffrey’s, and Anchor Steam.

    U System –  This system takes its name from the English manufacturer UEC. Used by breweries such as Guinness and Harp.

    Twin Probe – This system is in limited use by some regional micro-breweries.

    Home Brew – Ball lock fittings used for homebrew tanks.


    As there are literally tens of thousands of breweries and brands of beer available, it's simply not possible for Micro Matic to maintain a listing of the sizes of keg or area in which each brand of draft beer is available. For those brands of beer not covered in our listing, we recommend simply inquiring about the keg coupler system with the company you are purchasing your kegs from. If they do not know, they can make a quick call to the beer distributor or brewery to find out this information for you.
