Outstanding dredge vacuum and long life

Proline offers one of the most comprehensive line of pumps in the small dredge industry. These are high performance centrifugal pumps designed specifically for operating our dredges and dual-purpose machines. Each pump is cast in the US from premium quality A356 aluminum, then heat treated to a "T-6" hardness for years of service. Every component is then machined on computer controlled equipment to ensure the exact tolerances required for optimum performance. We use 5, 6, and 7 vane "aggressive bite" impellers with large intake throats to provide high volume with greater working pressure than similar pumps on the market. They are hand-assembled using US made seals, heavy duty reusable gaskets, and grade 8 hardware. The quality and performance of these units, when coupled with our efficient jetting systems, offers outstanding dredge vacuum with very little service required.
