The compact VH slurry pumps, which can be used as a priming pump or a booster pump, are compact and work in a vertical as well as horizontal position. The heavy duty design of the VH slurry pump is resistant to abrasive metallurgies and the slow running SP electric motor offers wear and tear resistance.

The Toyo patented built in agitator lifts sediments into suspension and creates a homogeneous mixture making continuous pumping of large quantities of solids possible. The VH pumps can handle slurries with up to 60% of solids by weight and particles with up to 80 mm diameter at an operating depth of 30 m. The capacity of the VH slurry pumps from Toyo can reach 210 m³/h and their manometric head 40 m.
