The Toyo DV pumps are extra heavy duty vertical pumps. They are designed for the handling of slurries with high solids contents and for the installation in deep pits. These heavy duty slurry pumps feature semi-open or closed impeller, a strong shaft perfectly tighten with no cure bearings and a double mechanical seal or an assembly of special lip seals operating in an oil bath. Adjustable wear plate allows long maintaining of high performances.

The DV pumps are driven by powerful slow running high torque electric motors. These motors are air cooled and can be provided in an explosion proof version. Servicing and maintaining the pumps is particularly easy on DV models. The impeller, the wear plate and the agitator are manufactured in high chrome cast iron (24 to 28%).

DV pumps are able to lift up and transport slurries with densities of at least 1.35kg/dm³ and can handle solids content reaching 70% by weight. They offer pumping capacities of up to 720m³/h. They can handle solids particles with up to 120mm diameter, in slurries temperatures of up to 60°C and pH between 4 and 9.5. Special versions are available for liquid temperature up to 80°C and the wet parts can be furnished in different metallurgies including stainless steel.
