The PV/PVT series Denison hydraulic pump is an axial piston variable displacement hydraulic pump suitable for open circuits, and its design focuses on the economy of operation. The PVT series is a derivative series of PV pumps with rear drive and side oil port configuration. The variable forms include: pressure compensated (constant pressure) variable, pressure compensated variable with remote control port, load sensing variable, and torque limited (equivalent to constant power) variable. The continuous working pressure can reach 280bar. DENISON plunger pumps have been widely used in high-pressure and variable demand industrial fields, and have received high recognition in the industrial field.
