Title: Dean L Schaffran: Innovator in Liquid Pump Technology

Introduction

Dean L Schaffran is a notable inventor based in Westminster, CO (US). He has made significant contributions to the field of liquid pump technology, holding 2 patents that showcase his innovative approach to engineering solutions.

Latest Patents

One of his latest patents is the "Liquid Pump Pressure Control System." This invention features a self-contained liquid manifold that can be attached to a drive mechanism for a reciprocable pump. The manifold includes a pumping cylinder, pressure transducer, pressure control mechanism, drain valve, and liquid delivery outlets, all integrated into a cohesive system. The design allows for easy removal from the drive mechanism by detaching just two fasteners. The pressure transducer and control mechanism utilize a piston and cylinder that can be indexed in a manifold bore, along with an electrical switch housed nearby, which enhances the functionality of the system.

Another significant patent is the "Proportional Pumping System." This system is designed for pumping liquid materials using reciprocating pumps driven by hydraulically operated motors. The hydraulic oil that powers these motors is supplied through reciprocating proportioners, which are driven by a reciprocating air motor operating under predetermined air pressure. This innovative system is characterized by its ability to stall the air motor under blocked output pressure conditions, thereby limiting the hydraulic oil pressure and, consequently, the pumping pressure applied to the reciprocating pumps.
