Latest Patents
One of Gravelle's latest patents is an impeller-type pump system. This system features a housing that defines a pump chamber and a fluid inlet communicating with the chamber. The impeller is rotatably mounted in the pump chamber downstream of the inlet and includes a rear magnet hub that mounts an axially facing driven magnetic coupling. Bearings are strategically placed around the impeller to ensure smooth rotation within the pump chamber. Additionally, ceramic barrier discs are positioned behind the impeller to seal the rear of the pump chamber effectively.
Another significant patent is for a centrifugal pump with hydraulic thrust balance and tandem axial seals. This design incorporates an impeller with front and rear axial seals that operate in unison to minimize leakage. The hydraulic thrust balance is maintained through axial movement of the impeller shaft, which modulates the gap at the rear axial seal. This innovative approach allows for effective pressure control, counterbalancing thrust forces acting on the impeller.
