Cast iron build on this thing -- does that hold up alright running hydraulics in a dump truck day in and day out?
Answer by: Customer Support on Mar 3, 2026, 6:49 AM
Cast iron is about as solid as it gets for heavy-duty hydraulic work. On a dump truck where you're dealing with constant pressure cycles and vibration, the material holds its own a lot better than aluminum alternatives. The intra-vane cartridge design also helps keep noise down during operation, which matters when the pump is working hard through repeated lift cycles.
