What is vertical shaft pump?
Vertical immersion pumps, also referred to as vertical shaft pumps or column pumps, are a pumping technology with an elongated shaft encased in a column to separate the motor from the pump.
How do you read a vertical turbine pump curve?
Start on the horizontal axis and select the desired flow capacity you need. Move upwards and see where that point on the axis intersects with the charted curve. If the chart contains several curves, stop at whichever curve represents the amount of power input/horsepower you expect to be using.
How do you adjust a vertical turbine pump for maximum efficiency?
Check head shaft to determine if it has right or left hand threads. As you rotate the shaft, raise impellers by tightening the nut on top of the head shaft. Continue tightening the adjusting nut until impellers begin to drag on the top of the bowl. Do not over tighten-this could pull impellers from shaft.
Where vertical pumps are used?
Vertical Pump Applications These pumps are usually used in wells to supply the water to agricultural otherwise grass irrigation. These pumps can also be used to pump the water from a river, a bored well, and reservoir.
What is vertical inline pump?
Vertical inline centrifugal pumps, as their name implies, are single stage centrifugal pumps that are specifically designed for vertical installation. Their suction and delivery are inline to provide a smooth flow of liquid through the system.
How do vertical pumps 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.
When would you use a vertical pump?
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.
What is vertical centrifugal pump?
The OL Series vertical centrifugal pumps are designed for handling the corrosive fluids involved in waste treatment, sump draining, tank transfer, agitation, and wet process and other industrial applications. Standard Pump, Inc.
How do you size and select a pump?
In pump sizing, two factors are needed to select a pump: flow and pressure. Flow is generally measured in gallons per minute (gpm). The max instantaneous flow that will be entering the pump’s basin needs to be determined so that a pump can be selected to efficiently maintain the system.
What does pump size mean?
Pump sizing involves matching the flow and pressure rating of a pump with the flowrate and pressure required for the process. The mass flowrate of the system is established on the process flow diagram by the mass balance.
How do you read a pump size?
Pump Size Number The size of the pump, 1-1/2 x 3 – 6 is shown in the upper part of the pump curve illustration. Note that the size number 1-1/2 x 3 – 6 indicates that the pump has a 1-1/2 inch discharge port, a 3 inch suction port, and a maximum nominal impeller size of 6 inches.
How does a vertical turbine pump work?
Water enters the vertical turbine pump through a bell-shaped port known as the suction bell. Once there, the water is accelerated by the first impeller, which is powered by a long shaft extending from the surface. Once the water is accelerated, it moves into the diffuser bowl directly above the impeller.
What are the different types of vertical turbine pumps?
Close coupled vertical turbine pumps with submersible motors. Vertical enclosed shaft pumps for sewage and wastewater. Vertical turbine fire pumps for onshore and offshore applications.
What are the applications of vertical pumps?
Vertical pumps for handling water in large volumes. Close coupled vertical turbine pumps with submersible motors. Vertical enclosed shaft pumps for sewage and wastewater.
What is a short set vertical turbine?
Short-Set Vertical Turbine. Instead, the pump shaft is rigidly coupled to the motor shaft, and the motor bearings are designed to handle the weight of the shaft and impellers, as well as the downthrust generated while the pump is in operation.
What is the maximum length of a well pump?
Deep-set well pumps range in length from around 100 feet all the way up to around 1,000 feet, and settings between 200 and 400 feet are common. Deep well pumps are used for irrigation water in many parts of the country, as well as for drinking water supply.
