NDP-(P)20BS Air-Operated Double Diaphragm Pump
The compact diaphragm pumps for various applications
The compact NDP-20 chemical pump with a capacity of up to110 l/min is capable of providing a head of up to 70 meters. The connection size is 3/4 inch (20 mm).
The Yamada NDP-20 series are compact double diaphragm (AODD) air-operated pumps in the Yamada line, featuring a 3/4" port size and a maximum capacity of up to 110 liters per minute. This compact pump is designed for precise fluid transfer in confined spaces for chemical dosing, sampling, laboratory processing and electronics manufacturing.
The housing, made of SUS316 Stainless Steel, provides chemical resistance and explosion-proof for flammable, food products, aggressive compounds or lubricants. 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-20 is a reliable solution for ultra-low cost, high-precision fluid handling.
