About this item
The Boss Tandem Pump Group G3 + 1P is a dual-stage, positive-displacement hydraulic gear pump designed for split-circuit applications. It couples a heavy-duty Group 3 pump with a compact 1P pump on a single driven shaft, allowing one prime mover to power two separate hydraulic systems simultaneously. Built with a high-strength cast iron or extruded aluminium body, it delivers reliable fluid power under high pressure, making it a standard choice for vocational truck setups, tipper kits, and industrial machinery requiring multi-stage fluid flow.
