Inline pumps are designed as centrifugal pumps in which the suction and discharge connections are located on the same axis. Thanks to their compact structure, they can be connected directly to the pipeline and provide significant space savings within the system. Inline pumps are widely used in applications such as water supply, circulation, pressurization, HVAC systems, industrial processes, and similar applications. Their main advantages include a compact design, easy fluid intake enabled by low NPSH (Net Positive Suction Head) design, low noise levels, high efficiency, and ease of maintenance.
Inline pumps operate based on a single-stage centrifugal principle and are suitable for transferring clean liquids or fluids containing very low levels of solid particles. Having suction and discharge flanges on the same axis simplifies installation and maintenance processes. Inline pumps are generally offered with wet-rotor or dry-rotor motor options, as well as versions controlled by frequency inverters. Frequency inverter–controlled models optimize motor speed according to system flow and pressure requirements, resulting in improved energy efficiency and lower operating costs.
Pump casings and flanges are manufactured in accordance with ISO/EN standards. Compliance with these standards increases ease of installation and operational safety. Modular construction allows the pump to be quickly removed from the pipeline during maintenance. Motor efficiency class, coupling design, and frequency drive options help optimize energy consumption, vibration levels, and operating costs.
Applications of Inline Pumps
Inline pump models are preferred particularly in systems with limited space along the pipeline, thanks to having suction and discharge lines on the same axis. Their compact and modular casing structures allow fast installation and integration in various facilities. Quiet operation, low energy consumption, and continuous operating performance are the core advantages of inline pumps. Key application areas include:
- Building Technologies: Used in heating and cooling systems for hot water, chilled water, and general circulation lines. Inline pumps provide stable flow and head performance in air handling units, fan-coil systems, and underfloor heating applications. ModulA Red, ModulA Blue, and ModulA-D models contribute to reduced energy consumption in HVAC applications with high-efficiency motor options.
- Industrial Technologies: Used in process water supply, pressure boosting, heat exchanger circuits, filtration lines, and general liquid transfer. CSV and INM GenIO models deliver reliable performance in industrial circuits with wide flow and head ranges and robust construction.
- Marine Applications: Preferred for onboard freshwater, seawater, cooling water, and auxiliary circulation systems. CSV, INM, and INM Duo models offer solutions suitable for marine operations thanks to their corrosion resistance and low maintenance requirements.
