About this item
The Boss Hydraulics Group 2P – 1P Tandem Pump is a high-efficiency, dual-stage external gear pump designed to deliver independent hydraulic flows from a single drive shaft. By coupling a larger Group 2P front section with a smaller Group 1P rear section, this compact unit optimizes space and eliminates the need for multiple gearboxes or dual prime movers. It is specifically engineered for high-low systems or machinery requiring two separate operating circuits from a single power source.
