Product Questions & Answers

Got a machine running two separate hydraulic circuits off one PTO, would a tandem setup like this work for pulling flow to both at the same time?

Question by: Phil C on Jan 12, 2026, 6:31 PM

Tandem pump assemblies are built exactly for that kind of setup. Both 420-series piston pump sections share a common drive, so you can feed two independent circuits from a single power source. Whether you're running them together or keeping the flow separate depends on how your system is plumbed, but the assembly itself supports both approaches.
