Navtec Autoshift 7/8 Bore Hand Pump

Developed with America’s Cup teams, the Navtec Autoshift 7/8 Bore Hand Pump provides a lightweight pump with increased flow. The latest version of the Navtec Race Pump increases the size of the large bore pistons to 7/8″ and the small bore pistons to 1/2″, providing the maximum flow required for Grand Prix racing. Excess material is sculpted away, ensuring that the pump is as light as possible. Coupled with the A384 Race Valve, the Autoshift 7/8 Bore Hand Pump is at the heart of Navtec race hydraulic systems.
