Line Type Fire Pumps

Line type fire pumps are one of the most widely used systems within the scope of fire extinguishing solutions. Line type fire pumps, which are highly preferred especially in the industrial field, have many advantages. The most important among these advantages is the convenience of changing parts. Vertical shafts play an important role in the working principle of line type fire pumps, which are specially designed for easy replacement of parts. The body of the line type fire pumps, which has a single-stage structure, is volute type. In addition, the easy disassembly of parts makes these fire pumps easy to clean and maintain.

What are Inline Fire Pumps and What They Do?

Theuy have a direct and cyclic start feature with their low power electric motor. This feature makes it possible to work for a long time. It is requested that the fire extinguishing systems be ready to work at any time against possible fire risks. Electric motors used in line fire pumps can meet this demand.

Standards for fire pumps are determined by NFPA. NFPA (National Fire Protection Association) standards set out the principles that determine the basic requirements of fire pumps. All features of they are capable of meeting NFPA standards. The performance of the pump not only meets NFPA standards, but also provides the opportunity to be used in different areas of life.

What are Line Type Fire Pumps?

They are volute type pumps with a vertical shaft structure and a single-stage operating body structure. Centrifuge is used in line type fire pumps. Centrifuge is a device that performs its task in the system with circular rotational movement. This tool also creates the general working principle of them.

Line type fire pumps have an automatic air release valve called suction cup. In this way, situations that may prevent the system from working in possible risk situations are avoided. In addition, the manometers at the inlet and outlet measure the nominal flow rates and provide the appropriate pressure for the needs. In them, there is also a valve with sealing feature against freezing.

What Do Inline Fire Pumps Do?

They have been developed against fire risks and are widely preferred today. The most important feature of line type fire pumps, which are suitable for use in industrial areas, hospitals, factories and shops, is their small structure. It occupies less space compared to other fire extinguishing systems and provides significant advantages in terms of use in this area.

The easily removable structure of the line type fire pumps, which are only used with electric drive, makes it possible to easily maintain and clean. Therefore, it can be ensured that the fire suppression system is always ready to operate efficiently. In addition, the fact that they can be connected to a single pipeline provides convenience in assembly.

Where are Line Type Fire Pumps Used?

They are suitable for use in almost every industrial area. It is also a preferred fire extinguishing solution in high-rise buildings or large residential areas. In such structures, high pressure water is needed to minimize the fire risks. The performance of they have a structure suitable for transferring water at the requested pressure.

When choosing between fire pumps or solutions, attention should be paid to system performance. In particular, the quality of the material used in the system and its adequacy to provide sufficient pressure must be properly controlled. In addition, attention should be paid to whether the system is structurally suitable for the area to be used and this criterion should be considered in the selection process.


  • They are single stage, vertical shaft, line type volute body centrifugal pumps.
  • Pump performances comply with NFPA standards.
  • The single-suction, closed impeller is dynamically balanced against axial load with balancing holes and wear rings.
  • Pump and motor connection is made by means of an adapter and using a special rigid coupling.
  • Since the pump can be separated from the installation in such a way that its body remains connected to the installation, maintenance and repair operations can be carried out easily.
  • According to the NFPA fire standard, shaft sealing is provided with soft packings.
  • The principle of part interchangeability is adopted as a basis for the design. Thus, the supply of spare parts has been accelerated.
  • It provides ease of direct starting with low electric motor powers.
