Vertical Turbine Pump

Hello Guest,

Really none of the above.

At a stretch of the imagination, because a turbine has blades or vanes, it could be Category #5 = a "Vane Pump".

Kind Regards....

No because all listed pumps are volumetric pumps and the usual vetical pumps are centrifugal. Different principles of how the flow is generated.

all the pump types you mentioned are positive displacement pump.

Vertical Turbine pump are centrifugal type pump.

None of the above.

Hello,

None of The option given.

It falls under cenrifugal pumps. The only diffrence with respect to normal centrifugal pumps is that vertical turbine pumps has stationary vanes in the casing. They are high discharge and low head pumps and are usually have many stages in a single unit.

Dear sir,

We classify pumps to two maior categories:

1-Dynamic Pumps.

2-Displacement Pumps.

Your pump is a dynamic,turbo,centrifugal pump.

generally the vertical pumps are centrifugal pumps multicellular small N.P.S.H..

It falls under, believe it or not.. the "Vertical turbine Pump" category... and in most cases it will be a submersible pump.

The vertical turbine pump is "none of the above" as most have already said.

However, there are a couple misconceptions stated also. First, the pump is not usually a high capacity, low head pump. Conversely, it is a "high head, moderately low capacity pump". Hence, the term "turbine". This term means that the pump is a centrifugal pump having, usulally, more than one impeller. The centrifugal pump will pump its rated capacity and its rated head "per impeller". If the pump is rated at 100 GPM @ 25' of head, the first impeller, which discharges into the eye of the second, will add its head to the head of the second thereby doubling the rated discharge head. If a third impeller, or "bowl" as they are called, is added to the system it to will add its 25' of head to the other two, thus resulting in a pump that will now pump 100 GPM at 75' head. The idea of a turbine pump is to get increasing head to overcome high head conditions.

The next falsehood is that these pumps are usually submersible. There are "submersible turbine" pumps that use the same technology. However, a "vertical turbine" pump is not submerged. They use a standard vertical "C" or "P" flange motor, sometimes with a hollow shaft, and they have the bowls below the motor with shafts encased in a pipe column that can be very long at times.

It would be worth your time to Google Goulds pumps and view there SSV and submersible vertical turbine pump series for well and tank applications. some of them as you will see will be a pump with muti stages and motor sealed ready for underwater use.

I did exactly as you suggested. I "googled" Goulds Pumps and, under the heading of Products, I went to the subheading "turbine pumps". Under that section there was mention of "line shaft turbines" and "submersible turbines" as well as others, but no where did it refer to submersible turbine pumps as "vertical turbine" pumps. However, I do thank you for your interest in my comments.

Hi from Scotland

As a Pump Engineer i would like to reply as follows:-

The term Turbine Pump falls into two categories

The First is a Vertically mounted Centrifugal driven by a Steam Turbine - with a Turbine Shaft driving the pump through an integral Gearwheel to the pump - I know because I worked on the them

Secondly, the Turbine Pumps - Electrically driven - were of Byron Jackson manufacture and they were submerged pump ends....3 stage - discharging via a discharge flange 14" bore -

At the time, my crew were involved in removing dismantling, repairing and reinstalling

and just to show how how many "self styled pump engineers" are out there we had to repair some one elses mistakes carried out months before. They had replaced the Phos Bronze Bushes with H.D.P.E. - not even oil filled -

anyway that is another story
