Affectionately known around the industry as the slurry hog, this pump has been designed with an appetite to digest some of the toughest slurry applications around.

This is a hard wearing, heavy duty, state of the art slurry pump that comes standard in high chrome and CD4 MCU. Designed for optimum effi ciency, the DBH features a high effi ciency impeller and fl ow stabilizing vanes on the suction to increase effi ciency and reduce turbulence and resulting impeller wear.

There are three series available in the DBH line:

  • LH (Low head, averaging about 165 TDH)
  • HH (High Head, averaging about 360 TDH)
  • MD (Mine dewatering – high head, averaging about 500 TDH)

The DBH also features both a front and back pull-out design along with a heavy duty shaft with the added protection of a shaft sleeve that extends from impeller to seal. For ease of service, the DBH provides a patented impeller release mechanism and patented externally adjustable wear ring. Finally, the DBH design allows for the maximum range of sealing options which are easily interchanged on site without special modifi cation. This is an innovative machine.

    Toyo/Hevvy pumps in series

    Design and installation of a system of 3 pumps Toyo/Hevvy in series with a performance of 80m³/h @ 500PSI at a solid percentage of 20 % by mass. In this project, two 100HP motors and one 125HP motors were used. This system is equiped with a variable speed starter, for which we have supplied the equipment, tested it in our workshop with the customer's PLC and completed the start-up underground.
