NDP-(P)25BS Air-Operated Double Diaphragm Pump
The compact diaphragm pumps for various applications
NDP-25 compact chemical pump with a capacity of up to 160 l/min is capable of providing a head of up to 70 meters. Connection size 1" (25 mm), internal thread.
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 liquid transfer in confined spaces for chemical dosing, sampling, laboratory processing and electronics manufacturing.
The SUS 316 stainless steel 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 enriching the atmosphere around the pump with oil.
Whether used in portable systems, OEM equipment or controlled environments, the NDP-(P)25BS is a reliable solution for ultra-low cost and high-precision liquid processing.
