In-Line Centrifugal


In-Line Centrifugal Pumps Overview

Centrifugal pumps are best known for their reliable design and have two variations, horizontal and vertical. Most of them are horizontal pumps, but vertical in-line centrifugal pumps are just as functional and popular for industrial applications. Both vertical and horizontal pumps carry out the same task and have the same price range, but the main difference between the two pumps is the shaft placement. Both the pumps have an impeller that creates a centrifugal force to move the liquid from one section to another. 

Benefits of In-Line Centrifugal Pumps

The incline design has many benefits over standard horizontal centrifugal pumps. Here are some of them:

Space Efficient

Industry professionals prefer the in-line centrifugal pumps for applications requiring a smaller space. These pumps have their shafts “in-line,” reducing the need for extra space and allowing the same function. These pumps have a smaller footprint and motor configurations, perfect for minute applications.

Lower Net Positive Suction Head (NPSH) Rate

The NPSH rate is the pressure required by the machine to overcome frictional losses in the system. The positive head suction can cause energy loss and reduce the overall outcome. Fortunately, the NPSH rate for the in-line centrifugal pumps is much lower, reducing the friction levels. The pump components are in the same line, and the liquid does not require additional propagation pressure, which reduces the suction head pressure required.

Heat Resistance

The in-line centrifugal pumps are better suited for high-temperature and high-pressure environments, and these pumps can withstand more challenging environmental conditions and maintain functionality under strict conditions. The pumps can handle thermal expansion well, making them ideal for medical facilities, water treatment, etc.

Applications of In-Line Centrifugal Pumps

In-line centrifugal pumps have varied industrial applications depending on the user. Here are some common industries where experts use the in-line centrifugal pumps.

Water Circulation and Water Heating Industry

Industries that heavily rely on water circulation and heating require pumps that can function well under strict conditions. The majority of the fluid pumps can face performance issues under harsh conditions, but the in-line centrifugal pumps are highly reliable.

Boilers and Cooling Towers

The boiler and cooling towers require a pump to move liquids across a pipeline network. Temperature changes can impact most pump performance, but the in-line pumps have higher temperature resistance, making them ideal for industrial applications.

Air Conditioning Systems

Air conditioning systems need to move the liquid coolant from the air conditioner to the condenser, and in-line centrifugal pumps can help. The straight-line pumps can propagate the coolant liquid through the pipes which is ideal for air conditioning systems.

Factors to Consider for In-Line Centrifugal Pumps

The kind of centrifugal pumps you purchase has a long-term impact on the performance you will get. Here are some factors to consider for your next centrifugal pump purchase.

  • Type of pump
  • End flanges
  • Flow rate
  • Head
  • Number of stages
  • Power
Bottom Line

An in-line centrifugal pump is ideal for industrial applications, considering it because of its effective temperature resistance. The pumps can also create better pressure and maintain it, providing efficient liquid propagation.
