There are six basic types of casing strings:
- Conductor Casing.
- Surface Casing.
- Intermediate Casing.
- Production Casing.
- Liner.
- Liner tieback casing.
What are the three types of centrifugal pumps?
Single-stage, Two-stage, or Multi-stage.
Why vortex casing is used in centrifugal pump?
Vortex casing is a casing in which circular chamber is provided between the casing and the impeller. Vortex casing is helpful to increase pump efficiency by reducing eddies formation to a considerable extent.
What are the three types of casing?
The three basic casing types primarily used for centrifugal pumps are the single volute, double volute and vaned diffuser.
Which type of casing is used in centrifugal compressor?
A single stage casing for an integral gear centrifugal compressor is shown in Figure 3.8. 3 (Sundyne Compressor). (Courtesy of Sundstrand Corp.) This type of compressor is used in low flow, high head applications.

What are the two types of centrifugal pump?
What Are the Types of Centrifugal Pumps and Their Applications?
- Radial Centrifugal Pumps – The design of these pumps facilitates an outward motion flow, which an impeller speeds up. …
- Axial Centrifugal Pumps – These pumps produce flow from the propelling motion of the impeller vanes, in other words, via a lifting effect.
Why centrifugal pump casing is called involute casing?
Answer: Yes it does look like an involute that’s why it is called involute casing. The main reason behind this is that as the fluid moves through the casing some amount passes through the runner so, Q decreases and thus the velocity tends to decrease.
Why the casing of centrifugal pump is spiral?
Explanation: The volute (spiral geometry) of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. … But in this case, the total energy of the unit volume of fluid should remain constant for the flow to be continuous.
What is centrifugal pump and its classification?
Centrifugal pumps are classified as a subclass of dynamic axisymmetric turbomachines. Centrifugal pumps are used to convert the rotational kinetic energy to hydrodynamic energy to move the fluid. The rotational energy usually comes from an electric motor or an engine.
What is stuffing box in pump?
From Wikipedia, the free encyclopedia. A stuffing box or gland package is an assembly which is used to house a gland seal. It is used to prevent leakage of fluid, such as water or steam, between sliding or turning parts of machine elements.
What is double casing pump?
Double volute casings have two cutwaters located 180 degrees apart from each other. Normally a double volute pump can be identified simply by looking down the discharge flange: a noticeable vane is located inside the nozzle that divides the inner diameter of the discharge nozzle.
When water flows through the casing of a centrifugal pump?
The centrifugal pump works on the principle of forced vortex flow which means that when a certain mass of liquid is rotated by an external torque, the rise in pressure head of the rotating liquid takes place. In a centrifugal pump casing, the flow of water leaving the impeller is free vortex.
What is the most common type of centrifugal pump in use?
The most common centrifugal pump design is the end-suction pump. This type of pump combines a volute casing with a variety of impeller designs. Most typically, a radial flow impeller would be used, but in certain specialty applications, Francis-vane or mixed-flow impellers may be used.
What type of pump is a centrifugal pump?
A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers.
What is pump types of pump?
There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps. In centrifugal pumps the direction of flow of the fluid changes by ninety degrees as it flows over impeller, while in axial flow pumps the direction of flow is unchanged.
What is centrifugal pump with diagram?
Centrifugal Pump is a type of rotodynamic pump in which the flow through the pump is induced by the centrifugal force imparted to the liquid by rotation of the impeller.
What is compressor casing?
The outer casing surrounding a compressor rotor. In an engine with an axial-flow compressor, the stator vanes are mounted in the compressor casing.
What are centrifugal compressor parts?
A simple centrifugal compressor has four components: inlet, impeller/rotor, diffuser, and collector.
What is casing treatment?
Casing treatment is a compressor range extension technology that can be easily integrated in to most compressor systems without significant additional expense.
What is casing and its types?
There are five different types of casing pipe: Conductor Casing, Surface Casing, Intermediate Casing, liner String, Production Casing. … In general, casing provides structure and strength to the walls of the well hole so that it doesn’t collapse on itself.
What is casing function?
The casing forms a major structural component of the wellbore and serves several important functions: preventing the formation wall from caving into the wellbore. isolating the different formations to prevent the flow or crossflow of formation fluid.
