SlurryKat has introduced a higher-output Doda AFI HD45 centrifugal pump for umbilical slurry systems where large volumes have to be moved quickly.

The pump has typical flow rates of 600cu m/hour and has been tested with umbilical systems with 150mm and 200mm flexible pipelines, pipe sizes commonly used in the US, Canada, Russia and Estonia.

With traditional umbilical systems in the UK and Ireland normally using 100mm and 125mm pipelines over the past 15-20 years, there is a demand from larger contractors and farmers to move to these bigger, more efficient systems.

The pump is available as a tractor pto model or direct drive for coupling with an engine.

It houses a three-blade chopping system for handling heavy fibrous material and incorporates a Wida tungsten mechanical seal to protect the oil-filled driveline system.

The Doda is manufactured with a heavy-duty impeller and body housing, that should give longer life.

It comes complete with an 200mm or 250mm suction line depending on operator requirements.

The material is spread via a 320deg swivel outlet which is said to ease the delivery process.

Priming of the pump is carried out with a hydraulic vacuum primer or with an optional submersible pump, which can be placed up to 6m deep.
