Toyo VH pumps are heavy duty amphibious pumps. That means that they can work dry, as any other horizontal pump, but also submerged as any submersible pump. No additional device is necessary. The VH is an innovative machine.
The design of the pump associated with the powerful Toyo SP motor allows the pump to be both air and water cooled.
VH pumps feature semi-open impeller, large open passages for the easy passage of solids, heavy duty shaft and bearings configuration, double mechanical seals working in oil bath and 4 pole customs built electric motor with 1.25 service factor.
VH15 and bigger models are equipped with an adjustable wear plate which allows optimizing hydraulic efficiency of the pump.
The impeller, the wear plates and the agitator are manufactured in cast chrome iron (24 to 28%).
The VH pumps can work as a priming pump and as a booster pump. They are supplied fixed on a frame with a strainer or with a fixing cone and with or without agitator.
These pumps have a side outlet discharge but can also be ordered in a very compact version with inline outlet discharge notably for tunneling works. High head versions are available.
VH 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 210m³/h.
They can handle solids particles with up to 80mm diameter and liquid temperatures up to 60°C with pH levels between 4 and 14. Special versions are available for liquid temperatures up to 80°C. The VH can also be furnished in different metallurgies including stainless steel.
Their maximum operating depth is 30m.
