Vertical turbine pumps are typically used where liquids need to be pumped up from groundwater surfaces (deep well pumps), artificial underground storage spaces (culverts) or open liquids. The new hydraulics and mechanical design make the vertical turbine pump an efficient, cost-effective and low-maintenance operation.
Introduction of Vertical Turbine Pump
Features of Vertical Turbine Pump
Application of Vertical Turbine Pump
Single or multi-stage vertical pumps with mixed or axial impellers and a wide hydraulic range are the best options for your specific application conditions. The combination of the dispenser, shaft and bearing, mechanical or cast iron on the surface or underground can be designed to be an open or closed shaft to ensure a long service life. Standard gearboxes can be driven by NEMA VHS standard engines, VSS engines or diesel engines.

Vertical turbopump (VTP) is a rotary power pump, which uses radial or improved radial flow impeller in vertical configuration. VTP is usually a multi-stage pump, in which many levels of impellers are encapsulated in bowl assembly, and can also be classified as deep or short pumps.
Deep well turbines are usually installed in drilling, and the first stage impeller is located below the pump water level. These pumps are self-priming, usually multistage components, and are mainly used to transport water. Transporting water from deep wells to the ground is the main application of these pumps. These pumps carry water to treatment plants, irrigation sprinklers and faucets at home. Short pumps are very similar to deep well pumps.
In addition, VTP can be installed in the suction drum or below the ground to provide additional suction head for the first stage impeller. These pumps are usually used as booster pumps or other applications where low net positive suction head (NPSH) is available.
Another unique application of VTP is that pumps can run backwards and be used as hydraulic turbines to generate power. When used in this application, the suction nozzle becomes the outlet of the turbine and the discharge nozzle becomes the inlet of the turbine. The efficiency of a pump as a turbine is comparable to that of a pump. Care must be taken, so contact the manufacturer before using the pump as a turbine.For deep well pump, Submersible Deep Well Pump is also applicable
