RKA-F17 Series

Introduction
The RKA-F17 Series from AR North America is engineered for industrial cleaning systems powered by electric motors. Featuring a 1-1/8″ hollow shaft and a NEMA 182–184 frame flange, these pumps bolt directly to motors, eliminating the need for pulleys and belts. With nickel-plated brass heads, bronze connecting rods, and ceramic plungers, the RKA-F17 pumps are built for the most demanding stationary applications.
