Vertical Turbine Pump (VTP)
A Vertical Turbine Pump is a type of centrifugal pump designed to move water or other fluids from underground wells, reservoirs, or deep sumps. Its key characteristic is that the pump assembly (bowls and impellers) is submerged in the fluid being pumped, while the driver (electric motor or engine) is located above ground, connected by a long vertical shaft.
This differentiates it from a standard submersible pump, where the motor is also submerged and attached directly to the pump intake.
Key Components
Above-Ground Driver: An electric motor or diesel engine mounted at the top. It provides the rotational power.
Discharge Head: The topmost part of the pump, which houses the outlet, connects to the piping, and often contains the throttle bushing for column alignment and sealing.
Column Pipe (or Column Assembly): A vertical pipe that encloses the long line shaft. This shaft transmits the torque from the driver down to the impellers.
Line Shaft: The long rotating shaft that connects the driver to the pump bowls. It has bearings (line shaft bearings) at intervals, lubricated by the fluid being pumped or an external clean water source, to maintain stability.
Pump Bowl Assembly: The submerged section of the pump. It contains:
Impellers: Usually multiple stages (multi-stage) to generate the required pressure/head.
Diffusers (or Bowls): Stationary components that surround the impellers, converting kinetic energy into pressure energy and directing the flow to the next stage or the column pipe.
How it Works: The above-ground driver rotates the line shaft. The shaft spins the impellers within the bowl assembly. Fluid is drawn in at the bottom intake, pushed through the stages of impellers and diffusers (each stage increases the pressure), and then forced up the column pipe and out through the discharge head.
Main Advantages
Ease of Maintenance: The motor is easily accessible above ground. The entire bowl assembly can be pulled out from the well or sump for inspection or repair without needing to excavate or de-water the area.
Efficiency and Performance: Excellent for high-flow, high-head applications, especially deep wells. Multi-stage designs allow them to generate very high pressures.
NPSH (Net Positive Suction Head) Advantage: Because the first impeller is already submerged, they have superior suction characteristics and are not prone to cavitation issues that affect surface pumps.
Space Saving: The vertical design has a very small footprint above ground, making it ideal for confined spaces.
Applications
Vertical Turbine Pumps are versatile and used in numerous industries:
Water Supply: Municipal water wells, industrial water extraction.
Irrigation: Large-scale agricultural irrigation from deep aquifers.
Circulation: Cooling water circulation in power plants and industrial processes.
Fire Protection: Often used as firewater pumps in large facilities.
Flood Control & Dewatering: Used in deep sumps for mines, construction sites, and stormwater management.
Oil & Gas: Seawater injection pumps on offshore platforms.
