Product Overview
The IWAKI APN-085VX1-1-22 is a precision-engineered diaphragm pump from the renowned IWAKI APN series, designed for reliable transfer and metering of aggressive chemicals, high-purity fluids, and industrial process liquids. Utilizing a positive displacement diaphragm mechanism driven by an eccentric cam and connecting rod, this pump delivers smooth, pulse-reduced flow without the need for shaft seals or packing, eliminating leakage paths and minimizing maintenance. The APN-085VX1-1-22 is a pneumatically or motor-driven unit (depending on configuration) that serves as a critical component in chemical dosing, water treatment, and industrial fluid handling systems where containment integrity and dosing accuracy are paramount.
