The VQ series vane hydraulic pumps are the pioneers of cartridge-design vane pumps. They are well known for long operating life, outstanding efficiency, flexible configuration and easy serviceability. The quiet 12-vane V series hydraulic pumps are the most popular medium pressure industrial fixed hydraulic pumps in the world. For mobile equipment, the unique flex plate in the VQ hydraulic pumps adds superior start-up capability in cold and harsh outdoor work environment. That's why the VQ series hydraulic pumps are widely adopted by world's leading mobile OEMs. Specifications: Max. Continuous pressure up to 3000psi. Displacement up to 11.8in3/ rev. Speed up to 2700rpm. Available in single, double, triple and thru-drive pump frames.
Dynao supply 20VQ, 25VQ, 35VQ, 45VQ, 2520VQ, 2525VQ, 3520VQ, 3525VQ, 4520VQ, 4525VQ, 4535VQ, etc. Single and Double Fixed Displacement Vane Pumps. All VQ Series Vane pump supplied by Dynaco hydraulics company are completely interchangeable with Vickers parts at lowest cost.
