Latest Patents

One of Gregory's notable patents is the sanitary design gear pump. This invention features gear shaft bearing blocks located in opposed cylindrical portions of the pump body bore. The design allows for hand-removable structural pump ends, facilitating easy cleaning and maintenance. The gear shaft bearings extend completely through the blocks and are sealed by O-rings and clamp plates. The oval gear cavity bore is designed to accommodate interchangeable gears, while seals at the end of the gear cavity eliminate entrapment zones. This innovative design minimizes the intrusion of bearing blocks into the gear cavity, allowing for a large operating temperature range. Additionally, the shaft seals are contained in a hand-removable cartridge, enabling complete pump disassembly with a single manually operated clamp. The gear shaft diameters differ to ensure correct assembly, and the mount allows for pump removal without changing pump-drive alignment.
