Is a pipeline pump useful for pressurizing? Before clarifying this question, let’s take a look at the definition and characteristics of a pipeline pump.

Definition: What we call a pipeline pump refers to a centrifugal pump whose inlet and outlet are on the same straight line, so the pipeline pump is also called a pipeline centrifugal pump. Pipeline pump is not a professional term in the pump industry. It is a private term based on the characteristics of the pump – when installed, it is installed on the pipeline just like a section of pipe, so it is named pipeline pump. Figures 1 and 2 below show typical vertical single-stage pipeline pumps and vertical multi-stage pipeline pumps.

As shown in Figure 1, it is a vertical single-stage pipeline pump, and Figure 2 is a vertical multi-stage pipeline pump, with the same inlet and outlet, which is very convenient to install. In particular, the vertical multi-stage pipeline centrifugal pump is now widely used in the water supply field. Typical products are CRF vertical multistage centrifugal pump

Features: Since pipeline pumps are centrifugal pumps, they naturally have the characteristics of centrifugal pumps, including not only simple structure, numerous models, wide range of performance, relatively low price, especially the feature that the inlet and outlet water are in the same straight line, which makes installation more convenient. , It is not necessary to disassemble pipes etc. during general maintenance.

Summary: Pipeline pumps are cheap, easy to install and do not need to dismantle pipelines during general maintenance. These three characteristics determine that pipeline pumps are widely used in pipeline pressurization in industrial and civil fields. Including not only the pressurization of industrial production water, the pressurization of various cooling circulating water, the pressurization of tap water pipes in various civil or commercial buildings, the pressurization of various central air-conditioning circulating water, etc.

It should be noted that there are subtle differences between pipeline pumps and pipeline booster pumps. Pipeline booster pumps are a general term, which means that any booster pump that can be used for pipeline boosting can be a pipeline booster pump. Pipeline pumps It is just a type of pipeline booster pump. Pipeline booster pumps may also include horizontal structures or vertical multi-stage centrifugal pumps with water inlet below and water out above. As shown in Figure 3, it is a typical vertical multi-stage centrifugal pump with bottom in and top out. It is also a pipeline booster pump, but it cannot be called a pipeline pump.
