An in-line pump, also known as a circulator pump, is a type of centrifugal pump designed for applications where a continuous flow of liquid is required. These pumps are characterized by their inline configuration, meaning the pump is installed directly within the piping system, eliminating the need for a separate pump room. In-line pumps are commonly used in heating, ventilation, and air conditioning (HVAC) systems, as well as in various industrial processes.

The design of in-line pumps allows for easy installation and maintenance, making them a convenient choice for systems that require a constant and controlled flow of fluids. These pumps are energy-efficient, with variable speed options available to optimize performance based on demand.

In-line pumps play a crucial role in maintaining temperature control in buildings, circulating hot water, and ensuring efficient fluid transfer in industrial settings. Their compact design and reliable operation make in-line pumps a preferred choice for applications where space and efficiency are paramount.
