Yamada Air Diaphragm Pump

Yamada model NDP-15FVT – 1/2″ Air Diaphragm Pump

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 chemicals 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 grit without damage.
