1. What is the maximum pressure to be attained?

You need to know the pressure that the system will have to reach, either now or sometime in the future. This does not need to be the usual working pressure, but the maximum pressure ever needed.

2. What is the required flow rate?

You need to know the required flow rate at the required discharge pressure. This is not the flow rate at the maximum pressure, but the flow rate at the working pressure. Remember that every booster has a maximum pressure where it will stall and produce no flow, but at any pressure less than that it will produce flow. This flow reduces in quantity as the output pressure approaches the stall pressure.

3. Is the flow rate constant?

Do you have a process application where you need a constant flow at a constant pressure? If so, then this is expressed as 'x' SCFM (NM3) @ 'y' PSIG (Barg).

4. Is the flow rate decreasing?

Do you have an application where you are filling cylinders or some other vessel from a lower supply pressure to a higher storage pressure. To select the proper booster or booster system, you need to know the size of the vessel to be filled. This can be supplied in any form that can be converted to ACF.

5. What is the required fill time for the vessel?

It is very common to have an initial fill times that is unrealistic. Many people who are not
familiar with gases ask for fill times that will require uneconomic systems. Therefore it is important to think about the longest possible fill time the application can stand.

6. What is the gas supply pressure?

The performance of any gas booster is a function of the incoming gas pressure. Simply stated: 'any gas booster will only discharge the amount of gas it takes in'. The higher the inlet gas pressure, the more SCF of gas are squeezed into the gas section and
therefore the more gas discharged. Gas supply can have more than one source. Therefore it can have many combinations of flow, pressure and temperature.

7. What is the drive pressure?

This is not the initial pressure in the system first thing in the morning before all of the uses of air are operational, but rather should be the minimum that the plant experiences throughout the day. The booster may have to provide maximum performance when the drive conditions are at their worst.

8. What is the gas?

Some gases cannot be pumped with standard boosters. They may require special seals, materials of construction, venting and other considerations. This is also important when higher pressures are required in filling applications to determine the compressibility of the gas. Applications involving gas boosters will always fall into one of four categories. It is very important to clearly determine into which category a particular application fits.

a) The supply pressure is at a constant pressure (Ps) and the discharge gas is at a constant flow (Q) and pressure (Po).

b) The supply gas is from a decreasing pressure and the discharge gas is at a constant flow and pressure. It is safe to assume that the supply flow rate will decrease as the supply pressure decreases. To maintain the constant outlet flow the booster will have to increase its cycle rate.

c) The supply gas is at a constant flow and pressure and the discharge gas it at an increasing 8 pressure.. It is safe to assume that the discharge flow rate will decrease as the discharge
pressure Increases.

d) The supply gas is at a decreasing pressure and the discharge gas is at an increasing pressure. It is safe to assume that the flow rate will decrease significantly as the pressures get further apart.

Liquid gas booster pumps are critical components in various industrial applications, providing the necessary pressure to transfer and utilize gases effectively. These pumps are designed to handle high-pressure requirements and ensure safe, efficient gas handling. This article explores the functions, applications, benefits, and selection criteria of liquid gas booster pumps.

Functions and Mechanism

Liquid gas booster pumps are engineered to increase the pressure of gases such as nitrogen, oxygen, hydrogen, and natural gas. They work by using a small volume of liquid (usually hydraulic oil) to compress the gas in a sealed chamber. The compressed gas is then discharged at a higher pressure, suitable for various applications.

Applications of Liquid Gas Booster Pumps

Liquid gas booster pumps are used across a wide range of industries due to their ability to handle high-pressure gas requirements.

Industrial Manufacturing

In industrial manufacturing, these pumps are used for processes such as pressure testing, leak detection, and gas cylinder filling. The ability to achieve and maintain high pressure ensures the reliability and safety of manufacturing operations.

Oil and Gas Industry

In the oil and gas sector, liquid gas booster pumps are employed for gas transfer, gas injection, and wellhead control. They are essential for maintaining the required pressure levels in pipelines and storage tanks, ensuring efficient extraction and processing of oil and gas.

Versatility

Liquid gas booster pumps can handle a variety of gases and are suitable for diverse applications. This versatility makes them an essential component in many industries, from manufacturing to aerospace.

Compact Design

Despite their powerful performance, liquid gas booster pumps often have a compact design, making them easy to install and integrate into existing systems. Their small footprint allows for flexible installation in confined spaces.

Selecting the Right Liquid Gas Booster Pump

Choosing the appropriate liquid gas booster pump involves considering several factors to ensure optimal performance and reliability.

Pressure Requirements

Understanding the pressure requirements of your application is crucial. Select a pump that can achieve and maintain the desired pressure levels without compromising efficiency or safety.

Compatibility with Gases

Ensure the pump is compatible with the specific gases you will be handling. Different gases have varying properties, and the pump material must be resistant to corrosion and wear caused by the gases.

Flow Rate

Consider the required flow rate for your application. The pump should be capable of delivering the necessary volume of gas at the specified pressure to meet operational demands.

Supplier Reliability

Choose a supplier with a proven track record of providing high-quality liquid gas booster pumps. A reliable supplier offers not only top-quality products but also technical support and after-sales service.
