Pump Priming Ejector is a Best Vacuum Ejector

The higher reliability and maintenance free operation ensures that the Vacuum Ejectors  are always up and running in the process. An excellent ability to generate and hold vacuum ensures exact operating conditions for the process.
The vacuum is formed when the pressure decreases from the atmosphere. So this is the main reason for designing Vacuum Ejectors. The system switches the energy of pressure of fluids to energy of velocity that is used for entraining the suction fluid.

Pump Priming Ejectors

  • The suction line of a Centrifugal Pump needs to run full of liquid for the pump to start with the pumping.
  • This creates a problem when there’s a positive height difference between the Pump Suction level and Sump liquid level. This height difference is known as Suction lift.
  • Hence the liquid needs to be drawn up to the pump level to ensure pumping start-up. The process of ensuring liquid presence in the suction line of the pump is known as Priming. The Priming process is a compulsory part of pump operation.
  • Improper priming results into formation of gas pockets in the pump impeller which prevent liquid flow.
  • Running the pump with improper priming leads to overheating of the motor and mechanical damage to the pump.

Ejectors for Pump Priming

  • Ejectors operate by creating a vacuum inside the suction line of the pump.
  • The vacuum draws the liquids from sump upto the pump elevation.
  • Vacuum Ejectors require a Compressed Air Supply as an Energy input. Easy availability of Compressed air and minimal flow requirement allows the Ejector to be easily accommodated by the existing facility.
  • Unlike other priming arrangements such as Foot Valves, Priming Tanks; Ejectors do not require any auxiliary liquid pump for its working.

        Ejectors are also superior to Vacuum Pump Technology for Priming due to the following reasons:

        Liquid Ring Vacuum Pumps require a Water/Liquid supply for their operation. In most of the cases Water/Liquid supply cannot be provided unless the Centrifugal Pump in question is started.
        Dry vacuum pump technology doesn’t tolerate liquid ingestion and is not economically feasible for the application.
        Vacuum Ejectors Pumps require considerable maintenance. The high maintenance cost drives the total Lifecycle Cost up.

        Applications Pump Priming Ejectors

        • Priming for Centrifugal Pumps with large size Suction lines (4” and more).
        • Priming for Seawater Pumps.
        • Priming for Corrosive Liquid Pumping.
        Our Engineers after carefully assessing the requirements of associated Pumping Systems have developed a specific set of rules for Priming Ejectors in order to achieve consistent Priming within minimum time with minimal Motive Consumption. Our Products and services provide value added and cost-effective solutions to various applications across the Chemical, Textile, Pharmaceutical, Food and Dairy, Steel and Petroleum Industry.

        Loop Reactor: Advancing Continuous-Flow Chemical Reactions for Efficient and Scalable Production

            Loop Reactors are revolutionizing the way chemical reactions are performed in the industry. They have been in use for many years and are becoming more prevalent as they offer many advantages over traditional batch reactors. In this article, we will discuss Loop Reactors in detail, including how they work, their benefits, and their applications. What is a Loop Reactor? A Loop Reactor is a type of continuous-flow chemical reactor used to perform chemical reactions. The reactor consists of a loop-shaped tube with a high-speed impeller located inside the loop. The impeller generates high shear forces that promote mixing of the reactants and enhance the mass transfer of reactants and products within the reactor. The loop-shaped design also allows for efficient heat transfer, ensuring that the reaction temperature can be tightly controlled. How Does a Loop Reactor Work? Loop Reactors work on the principle of continuous-flow chemical reactions. The reactants are continuously fed into the

        Tantalum Heat Exchangers for Highly Corrosive Applications

        Tantalum Heat Exchangers for Highly Corrosive Applications In order to achieve optimum process operations, it is essential to use the right type of process equipment in any given process.  Heat exchangers, commonly used to transfer energy from one fluid to another, are no exception.  Tantalum is the most corrosion resistant metal in common use today. It is inert to practically all organic and inorganic compounds. Its corrosion resistance is very similar to glass, as both are unsuitable for use in hydrofluoric acid and strong hot alkali applications.  For this reason, Tantalum is often used with glass lined steel Reactors as patches, Dip Tubes, Piping and Overhead Condensers. CrystalTCS offers a full line of standard and custom designed shell and tube heat exchangers for acids or highly corrosive media operations. Tantalum, the inert material for most acids and highly corrosion areas, when machined/ rolled and fabricated into heat transfer equipment increases the life and du
