Toyo GR pumps are heavy duty submersible slurry pumps. They offer true slurry pump design and real solids pumping effectiveness for a limited investment cost. These top outlet discharge pumps are self cooling pumps. They are therefore able to operate partially submerged. Standard they are equipped with thermal protection.

The design of the pump incorporates the renowned patented Toyo agitator, attached directly on the pump shaft, semi-open impeller, heavy duty shaft and bearings configuration, double mechanical seals working in an oil bath and 4 pole customs built electric motor with 1.15 service factor. GR15 and bigger models have an adjustable wear plate. The impeller, the wear plate and the agitator are manufactured in cast chrome iron (24 to 28%).

GR pumps are able to lift up and transport slurries with densities of at least 1.25kg/dm³ and can handle solids contents reaching 55% by weight. They offer pumping capacities of up to 192m³/h.

They are able to pump solids particles with up to 40mm diameter, in slurries temperatures of up to 60°C and pH between 4 and 9.5. They can be furnished in different metallurgies including stainless steel. Their maximum operating depth is 30m.
