Pump Up Foamer Parts and Customization Options

Pump Up Foamers are versatile chemical applicators for situations where water pressure is not available. Air from the tank is injected into the chemical solution, which creates foam quality similar to compressed air assisted foam.

Individual parts can be replaced as needed. Lafferty also offers parts to modify the wand and nozzle assembly to help achieve the desired coverage.

The frequency of replacement depends on how diligently best practices are observed and the amount of use/abuse received. Consider water or compressed air driven equipment to eliminate pumping and the associated maintenance hassles.

Refer to the parts diagram for your specific unit before ordering. Sprayers are visually similar but include several different components.

Chemical Compatibility Note:

Viton/Nitrile o-rings and seals are used in our standard configurations and replacement parts. These seals are suitable for a wide range of general purpose cleaning products.

Alternately, Pump Up Foamers and some individual parts are available with EPDM seals pre-installed. These parts numbers typically include -E and the end of the part number.

PRO TIP: It is typically more cost-effective to purchase a standard part along with an EPDM repair kit to utilize when the standard seals need to be replaced due to chemical exposure and normal use. (There are no user-serviceable seals in the trigger gun.) O-Ring Replacement Guide.
