IMS Dredge Booster Pumps
IMS currently manufactures two models of dredge booster pumps. Both feature John Deere engines and impeller and volute cast from high chrome Gasite iron construction. Standard equipment on each includes heavy-duty steel skid, lockable engine enclosure, service water pump, and partial automation (throttle up / throttle down.)

1 This represents total flow capabilities of the pump – water and solids.
2 This represents theoretical maximum solids production. This is calculated based on 25% solids by volume and 1 complete hour cutting and pumping material. This estimate does not take into account material properties, time used for positioning, pumping distance or elevation. Buyer should consult IMS for production estimates based specifically around their application.
Frequently Asked Questions
You need a dredge booster pump when the slurry must travel a long distance or uphill, beyond what the dredge’s main pump can move efficiently. Adding a booster in the pipeline maintains velocity and pressure so solids don’t settle, keeping production high over long runs or significant elevation gains. IMS will tell you whether your pipeline requires a booster.
A booster pump significantly extends pumping distance — the exact reach depends on material, solids concentration, pipe diameter and elevation, and multiple boosters can be staged in series for very long runs. IMS engineers calculate the achievable distance and how many boosters your project needs. Share your discharge route for a precise figure.
IMS manufactures two dredge booster pump models. The 1012 is a 10 in. (254 mm) × 12 in. (304 mm) unit producing 4,000 gpm (252 l/sec) at 170 ft TDH, powered by a John Deere 6090 rated 325 bhp. The 1008 is an 8 in. (203 mm) unit producing 3,500 gpm (220 l/sec) at 140 ft TDH, powered by a John Deere 6068 rated 250 bhp. On both, the impeller and volute are cast from high-chrome Gasite iron for long life in abrasive slurry, and both sit on heavy-duty steel skids that fit inside an ocean container. Electric-drive versions are also in service. Request the booster pump spec sheets for full details.
The number of booster pumps depends on total pumping distance, elevation change, pipe diameter, slurry solids and the dredge’s pump curve — boosters are added wherever pressure would otherwise drop below the level needed to keep solids moving. IMS performs this hydraulic calculation for your specific pipeline run. Provide your distance and elevation profile for a staged recommendation.
Yes. IMS booster pumps are designed to be added inline to an existing dredge pipeline to extend its reach, and they can be matched to many existing dredge setups. This lets operators increase pumping distance without replacing their dredge. IMS will confirm compatibility with your current system.
The main dredge pump is submersible and ladder mounted behind the cutterhead on the dredge itself, where it creates the suction that lifts material from the bottom. A booster pump sits further along the pipeline and re-pressurizes the slurry so it keeps moving over long distances or uphill. The dredge pump starts the flow; the booster keeps it going. Both use abrasion-resistant, high-chrome components built for slurry duty.
