Easy to operate - just push down on pan and it automatically pumps liquids into pan to moisten sponge or rag.  Surplus liquid drains back. Reduces the danger of exposed liquid. Perforated pan screen also serves as a flame arrester.  Unique "Smart Pump" mechanism works up to a mere 1/4" fluid level saving time by refilling less often.  More liquid comes to the top for easier moistening.  Pump is constructed of brass and Ryton for chemical resistance.  Galvanized steel body is finshed in a durable powder paint for long life.  FM aprroved.  FOB Shipping Point.
