Four patents are held on these pumps, plus a design patent application. The first patent covers the automatic re-closing of hydraulic chevron seals. The second innovation covers a new compressed-air exhaust system. The third patent covers access to the pump’s lower valve and the ball. The fourth patent is based on the suction rod. Patent filings protect us against copying, while design patent applications, protecting the hood designed by the SAMES KREMLIN teams, are aimed at making the pump more visually distinctive. These pumps will be available wall-mounted or cart-mounted.
