Air-Operated Double Diaphragm Pump NDP-5FST

The Yamada NDP-5 series is the smallest air-operated double diaphragm (AODD) pump in the Yamada line, featuring a ¼" port size and a maximum flow rate of up to 11 liters per minute. Designed for precise fluid transfer in confined spaces in chemical dosing, sampling, laboratory processing and electronics manufacturing, this ultra-compact pump is designed for precise fluid transfer in confined spaces in chemical dosing, sampling, laboratory processing and electronics manufacturing. 

The body, made of SUS316 stainless steel, provides high chemical resistance and flexibility for aggressive or high-purity environments. Compared to the small size, it provides reliable leak-free operation with 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-5 is a reliable solution for ultra-low cost and high-precision liquid processing.
