The Yamada NDP-25 series are compact double diaphragm (AODD) air-operated pumps in the Yamada line, featuring a 1" female port size and a maximum capacity of up to 160 liters per minute. This compact pump is designed for precise fluid transfer in confined spaces for chemical dosing, sampling, and other applications.
The cast iron housing provides chemical resistance to aggressive acids and alkalis. Despite its small size, it provides reliable, leak-free operation thanks to Yamada's proprietary oil-free air valve system. This ensures smooth operation and ease of maintenance, without adding oil to the atmosphere around the pump.
