Product Overview

The HLK-91100 series HPU provides a versatile range of input power options, making them suitable for the majority of ROV systems available today. Designed with adaptability in mind, they are particularly well-suited for small to medium-sized ROVs and manned submersibles, delivering reliable hydraulic power for operating manipulators, pan and tilt mechanisms, and other low-flow tooling. These units can also serve as compact hydraulic power sources for larger work-class vehicles.

The pump manifold features a direct-acting pressure relief valve, which offers infinite adjustability between 0-207 bar, depending on the pump size.
