1. What Are Vertical Turbine Pumps and
Their Application?
Vertical turbine pumps and submersible turbine pumps are the two primary types of turbine pumps.
While submersible pumps have the electric motor submerged at the bottom of the pump, vertical turbine
pumps have the motor above ground, connecting to the impellers at the bottom of the pump by a long
vertical shaft. The term “turbine” in the pump’s name is a misnomer because this pump has nothing to do
with a turbine.

2. Vertical pumps are comparable to ordinary pumps, but they have a few distinct applications. Pumps
transform mechanical energy into kinetic energy and increase the pressure of the liquid by using
centrifugal force. Vertical pumps are used to transfer liquids up a pipe in a vertical direction. Pumps are
used to pressurise liquids that are mainly incompressible. Liquids, unlike compressible gases, cannot be
compressed, hence the volumetric flow rate cannot be lowered. Pumping is used to transfer liquids, and
the entrance volume flow rate equals the exit volume flow rate.
Vertical centrifugal pumps are comparable to horizontal centrifugal pumps in that they are simple
equipment with similar designs. An impeller is positioned perpendicularly on an upright (vertical) rotating
shaft in a case known as a volute. The electric drive motor transfers kinetic energy to the liquid when it
begins to rotate by using its mechanical energy to turn the pump impeller with blades. These pumps can
be single or multistage, with many in-line stages connected in series.
The impeller rotor’s centrifugal force forces the liquid and any particulates inside it to flow radially
outward at high tangential velocity away from the impeller’s centre of rotation. The swirling flow exiting
the impeller is then directed into a diffusion system, which can be a volute or a collector, that diffuses the
high velocity flow and transforms it to high pressure. The high exit pressure of vertical pumps allows
fluids to be pumped to high vertical places. As a result, the liquid is lifted to high levels using the pump’s
exit pressure force, which is normally at a high residual pressure even at the pipe discharge.

3. A turbine pump is a multistage vertical pump with multiple stages. Vertical turbine pumps are multistage
with double casings and can be radial or axial. Depending on the needed lift pressure, or pressure head,

4. the stages are lined together and can be stacked. They can be employed in a range of high-pressure
applications, including functioning at extreme temperatures and handling tough liquids. These are used
in the mining, water resources, power generation, and oil and gas industries.
Vertical turbine pumps are used in a variety of applications, including agriculture, condensate
extraction, crude, product, and CO2 pipelines, dewatering and water supply (mining), gas treating and
sulphur recovery, ground water development and irrigation, water and CO2 injection, nuclear service,
offsites and waste treatment, snowmaking, water supply and distribution (water), water treatment, and
pumping LNG.
The most common application for these pumps is raising and carrying water, which has a wide range of
applications in domestic, general-purpose, industrial, and commercial settings. In waste water and
sewage treatment plants, vertical centrifugal pumps are utilised to manage trash and refuse, as well as
abrasive slurries. Pumping combinations of particles suspended in liquid is possible with some
heavy-duty types. Vertical pumps are used as water pumps to carry water from underground sources to
structures for human use or to mitigate flooding and drainage problems. Vertical pumps may pump
chemicals and acids if they are made of corrosion-resistant materials, which is a helpful way of
transferring hazardous liquids around a processing plant.
