NDP-25BA 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 housing, made of ADC-12 Aluminum alloy, provides chemical resistance to aggressive liquids based on solvents, petroleum and organic acids. Despite its small size, it provides reliable operation without leaks thanks to the proprietary Yamada air valve system, which operates without lubrication. This guarantees smooth operation and ease of maintenance, does not enrich the atmosphere around the pump with lubricant.
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.
