Latest Patents

Couch holds a patent for a "Positive displacement screw pump having pressure feedback control." This invention introduces improvements in screw pumps, especially positive displacement pumps. The design features an increased clearance between the screw flight and the bore over an extended period. Additionally, the screw is balanced at preferred locations on the flight. To combat wear, hard materials such as tungsten carbide are applied to portions of the outer surface of the screw flight. A unique wear measurement port allows for monitoring wear on the pump screw during operation without the need for disassembly. This is achieved by using a proximity sensor connected to a monitor, enabling real-time wear assessment while the pump is functioning.
