Airport The Yamada 2" aluminum air operated dual diaphragm pneumatic pump is a workhorse of a pump that can be used in a variety of industries. It is an environmentally friendly non-lube and non-stalling air powered double diaphragm pump with aluminum wetted materials of construction and Buna N diaphragms.
This dual diaphragm pump NDP-50BAN is an excellent choice for two-man sealcoat spray system teams or sealcoating bar systems.
When used as a sealcoating pump on single man spray systems, the 2" pump is honestly overkill, however its large size makes it a fantastic "low duty cycle" pump that cycles less than the popular 1.5" Yamada pump if that's what you're looking for in a pump.
