Product Overview
The ARO 650718-C is a pneumatically driven piston pump engineered for reliable transfer and dispensing of fluids in demanding industrial environments. Operating on a reciprocating piston principle, this pump converts compressed air energy into hydraulic fluid movement through a balanced air motor and piston assembly, delivering consistent volumetric output without the need for electrical power. As part of the ARO family of industrial pumps, the 650718-C is designed for continuous-duty service in fluid handling systems where precise displacement, self-priming capability, and resistance to harsh media are essential. Its piston-type construction provides positive displacement performance suitable for high-viscosity fluids, making it a dependable component in centralized lubrication, chemical transfer, and process fluid circulation circuits.
