Understanding the differences between these two types of pumps is critical for selecting the right equipment for specific tasks. This article explores the working principles, performance, operation process of self-priming pump .
A cap screw pump is a type of screw pump known for its easy and reliable construction. It is designed with three screw spindles, two of which are driven screws while the third screw acts as the driver. The design of the cap screw pump allows for enough clearance between these screws, which plays a crucial role in its efficient operation.
A screw pump is a type of pump that uses a set of screws to pump fluid from one area to other. Ituses one or more screws to move fluids or water along the axis of the screw. The screws of the pump are interlocked to pressurize the fluid and move it inside the system. These screws are meshed with each other
What is a Screw Pump?
A screw pump is a positive displacement pump that operates by using one or more screws to move fluid along the screw's axis. This type of pump is commonly used in various industries for applications that require a steady flow of liquids with high efficiency.
Screw Pump Design
The design of a screw pump is relatively simple yet effective. It typically consists of a casing, screws, bearings, and seals. The screws are the main components responsible for moving the fluid through the pump, while the casing provides support and protection for the internal components.
3 Screw Screw Pump
The cap screw pump falls under the category of 3-screw screw pumps, which are designed with three intermeshing screws. This configuration allows for a higher flow rate and increased efficiency compared to single-screw or twin-screw pumps.
Screw Pump Operation
The operation of a screw pump involves the rotation of the screws within the casing. As the screws turn, they create cavities that trap and move the fluid from the pump's inlet to its outlet. This continuous movement of fluid ensures a steady flow rate and reliable performance.
Screw Pump Housing
The housing of a screw pump is designed to contain the screws and provide a pathway for the fluid to flow through. It is typically made of durable materials such as cast iron or stainless steel to withstand the pressures and temperatures associated with pumping operations.
Screw Pump Function
The primary function of a screw pump is to efficiently transfer liquids from one point to another. It is commonly used in applications where a constant and reliable flow of fluid is required, such as in oil and gas production, chemical processing, and industrial manufacturing.

A screw pump has an easy and reliable construction. It is very easy to design. There are three screw spindles, two of which are driven screws and the other screw is a driver. There is enough clearance between these screws, which is responsible for
Point 2: x 2 = 0, y 2 = Shut-Off Head (SOH) The shut-off head is calculated using the formula: SOH=RPH (1+θ) Where θ = Head Rise to Shut-off Ratio. A 0.25 to 0.30 head rise to shut-off ratio is a reasonable value for centrifugal pump calculations. Usually, the lower the value the flatter the curve. A head rise to shut-off ratio of zero .
