PRESSURE WASHER ACCESSORIES Yamada Pumps Air-powered double diaphragm pump, “Reliable Performance Since 1905”. The answer to difficult product transfer problems. Air-drive allows freedom from electrical hazards or explosion-proof motor requirements. Choose from various wetted-parts materials to customize the pump to the chemical being pumped. Yamada’s smaller pumps are often used for pumping car wash chemical for ‘low-pressure’ functions. The 1/2" pump is also ideal for rapidly pumping oil, soap, etc., from 55 gallon barrels. Larger pumps are used for high-volume product transfer. Since all pumps are designed without rotating parts, they can also handle abrasive liquids such as ceramic slip, sand slurry, or enamel frit without damage. Have a unique challenge?
