What is a regenerative turbine pump?

Regenerative turbine pumps are centrifugal pumps for pumping pure liquids. They are used where great delivery heads are required with small volume flows. Due to centrifugal forces, the pumped liquid circulates several times out of the side-channel back into the impeller.

How does a vertical turbine pump work?

Vertical turbine pumps work when water enters the pump at the bottom through a bell-shaped part called the suction bell. From there it moves into the first stage impeller, which raises the water’s velocity.

Is a turbine pump a positive displacement pump?

Turbine pumps have characteristics of both centrifugal and positive displacement pumps. They contain a rotating impeller similar to centrifugal pumps, the difference being that the turbine pump has a turbine-like impeller. Turbine pumps are good for applications where high head and low flow are needed.

What is turbine driven pump?

Turbine pumps are special types of centrifugal pumps which use turbine-like impellers with radially oriented teeth to move fluid. These pumps combine the high discharge pressures of positive displacement or multi-stage centrifugal pumps with the flexible operation of centrifugal pumps.

What are vertical pumps?

Vertical turbine pumps are centrifugal pumps specially designed to move water from an underground well or reservoir. They’re also known a deep well turbine pumps or a line shaft turbine pumps. Vertical turbine pumps work when water enters the pump through a bell-shaped part at the bottom called the suction bell.

Which is more efficient turbine or pump?

The pump is inherently less efficient than a turbine because of smaller losses when converting pressure energy to kinetic energy than vice versa.

What are turbine pumps used for?

Turbine pumps are used in clean liquid applications that demand high head, low flow, compact design, and flexible operation. They’re used in a wide range of industrial applications such as cooling water circulators for lasers and other machines where high head is required.

Is a turbine pump centrifugal?

Turbine pumps are centrifugal in nature but have some characteristics of positive displacement. While that sounds oxymoronic, for different functions, they behave or operate differently. First, the way they impart energy to the liquid is kinetic (and hence centrifugal) in nature.

Why do we use vertical pumps?

When you have a restricted surface area and need a pump that takes up a much smaller footprint, vertical centrifugal pumps will definitely take up less floor space. They are well-suited for liquids with high temperatures and pressures, and the NPSH can be altered to handle a wider range of applications.
