Latest Patents

McMahon's latest patents include a gear transfer pump with lubrication and sealing of the driveshaft. This invention features an improved rotary gear within a gear transfer pump, which includes a pump housing with a circular pumping chamber that communicates with both a first and a second port. The design incorporates an externally driven rotor that meshes with an internal idler gear. To accommodate abrasive fluid mediums or non-homogenous pump fluids, the invention employs an idler gear seal and a shaft seal to contain the pumped fluid within the chamber. Additionally, a source of lubricating and flushing fluid is communicated to the idler gear bearing region and the shaft bearing. The innovative design ensures that fluid leakage across the seal interfaces is minimized, enhancing the pump's efficiency.

Another significant patent by McMahon is the rotary gear transfer pump having pressure balancing lubrication. This invention features an externally driven rotor that rotates within a pumping chamber and is in meshing relationship with an internal idler gear. A pressure balancing circuit is included to transfer pressurized fluid from the discharge region to the backside of the rotor, partially balancing the axial forces exerted on the rotor. The design also allows for bi-rotational capability, utilizing cross-communicating passages and check valves to control fluid flow. This innovative approach addresses the challenges of viscous friction when pumping high-viscosity fluids.
