Yamada NDP-15 Series 1/2-Inch Diaphragm Pumps

All Yamada NDP-15 series, 1/2-inch, air-powered double diaphragm pumps feature bolted construction, which eliminates leaks and simplifies post maintenance reassembly. Since the air valve is accessible from the outside, the Yamada pumps can remain in operation during inspections and valve maintenance. These self-priming pumps allow for high suction lift and may be easily adjusted to suit a wide range of pumping applications. Designed to eliminate rotors, gears, pistons and other wear parts, these Yamada pumps perform with extended life with low maintenance.
