This listing is for the pump only!

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 dredges.

These pumps are engineered for purpose and are direct bolt on to the Honda GX160 range of 5.5 Horse power engines. If looking for a pump with engine see dredging equipment for stock

You can purchase this pump alone and mount to an engine sourced locally or we can ship you a ready to use pump/engine combo.

As a single unit this pump will power a 4 inch dredge, as a dual unit (2 x GX160/HP350 Combos) will run a deep diving 5 inch with amazing lift.

It has a 2.5” intake and a 2” discharge.

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.
