Multistage Pump Reverse Engineering

To begin reverse engineering, the product’s preliminary information should be available. Therefore, it is important to know if the pump is widely used, whether a pump is intended for industrial and domestic use, or if it consists of two or multiple one-stage pumps. Reverse engineering multi-stage pumps allows for pumping water and liquids to heights with adequate pressure. In these pumps, all propellers are attached to one axis and placed in one casing. Reverse engineering multi-stage pumps should be done as follows. First, the information about the pump meant for reproduction should be acquired for use in the process. Pump type and operational conditions should be determined and performance specifications should be graded. The pump’s manufacturer and fluid type inside should be determined. The pump should be disassembled for manual dimensioning, and complex components, including the spiral casing and propeller, should be 3D scanned. Next, the pump’s technical plans should be produced for redesigning and manufacturing according to the component report and possible coatings. Acquiring a part list is very helpful in this stage. The hydrodynamic and vibration matching of the pump assembly’s hydraulic and rotating components is done if the customer demands according to reputable international standards of centrifugal pumps. The most important parts of multistage pump reverse engineering are the production process and control. The assembly and performance test estimations should be done according to reputable international standards on centrifugal pumps.

Reverse-engineering a multistage pump covers the following parts: Pump casing, which protects other components from external compounds, is made from strong alloy. These pumps are used for seawater, do not corrode, and are abrasion resistant. Another pump component is the propeller, a rotating disk with blades attached to the shaft. During operation, the propellers rotate to transfer kinetic energy to the fluid.

Another important part to multistage pump reverse-engineering is the pump motor. The motor moves the shaft and uses alternating current.

The valve is a primary component in multistage centrifugal pumps and has a fluid that controls pressure. This part is shaped like a curved funnel and its area increases closer to the discharge area.

The pump ball bearing reduces friction between the stator and the rotating shaft. The propellers support the ball bearing’s movement, and it should be oiled regularly.

Multistage pump also have other components, such as shaft, pump casing, hub, and sealant.

The shaft attaches the propeller to the motor.

Hub is the part attached to the ball-bearing where the engine is connected to.

Multistage pump reverse-engineering is a method of producing the customer’s required product without environmental design changes and additional costs. This method is useful for recovering and identifying a product’s components, especially if the initial design is unavailable, and helps customers to continue manufacturing products without redesign costs.

Reverse engineering is used for pumps and components of certain machines. Therefore, the main problem is access to the correct pump geometry. Components are measured with precision 3D scan using special cameras. The relevant specialist team begin the process and convert the cloud of points file with a set of points into the intended geometry for modeling and casting.

Multistage Centrifugal Pump

Engineers in reverse engineering use multistage centrifugal pumps extensively, which are widely-used multi-stage industrial pumps. Multistage centrifugal pump reverse-engineering is very important to the development of modern societies. A society’s current development depends on developing and re-engineering by its specialists.

Multistage centrifugal pumps are used in oil fields to transfer oil/petroleum residue and dirty oil. These pumps are also used in crude oil and petroleum product transfer lines and for water supply and various high-pressure water lines and seawater desalination machines. The multistage centrifugal pumps’ applications depends on temperature, flow, and head. These figures will vary for various pump applications.
