Liftgate service will move the item from the bed of the truck, to the ground ONLY. You must have a way to handle it on the ground. If you have a forklift, you don't need liftgate service which saves you money.
Quick Overview: 
  • High Quality 2" Aluminum Dual Diaphragm Pump
  • Excellent for medium to large sealcoating rigs
  • 1-year Limited Warranty
  • Up to 166 GPM
  • Air Powered (air source sold separately)


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.
