Title: John F Isais, Jr: Innovator in Pump Technology

Introduction

John F Isais, Jr. is a notable inventor based in Brooklyn Park, MN (US). He has made significant contributions to the field of pump technology, holding 2 patents that showcase his innovative approach to engineering solutions.

Latest Patents

His latest patents include a "Reciprocating piston pump with air valve, detent and poppets" and a "Mechanical proportioner." The reciprocating piston pump features an air valving system that utilizes piston-actuated poppet assemblies to control the main air valve shift. This design ensures reliability by venting the valve exhaust directly to the atmosphere rather than through the main exhaust. Additionally, a ramped detent prevents the air valve from centering. The mechanical proportioner is designed with two pump lowers connected by a yolk beneath an air-operated reciprocating piston pump. This configuration allows for a minimized center-to-center distance, enhancing efficiency. The mix manifold is constructed to prevent mixed material from contacting it until it enters the static mixer, which is easily disposable and replaceable. The design also includes interlock mechanisms for the purge solvent valves, ensuring safe operation.
