What is an inline pump?

Centrifugal pumps are the most widely used pumps in the world. Although most centrifugal pumps are horizontal, we also use vertical inline pumps in some space-constrained applications (the space occupied by the vertical installation solution is 1/3 - 1/2 for horizontal installation). Vertical in-line centrifugal pumps, as the name suggests, are single-stage centrifugal pumps designed for vertical installations, its suction and discharge connections are in a straight line. Vertical centrifugal pumps are often used to transport clean water and other liquids that are physically and chemically similar to clean water.

How to choose the right pump material for my application

  1. Mainly check the compatibility of the material of the pump flow parts (pump casing, impeller, O-ring and mechanical seal) with the pumped fluid.
  2. When a variety of materials are suitable, consider the material with the most comprehensive cost and the lowest cost

Why choose an inline centrifugal pump?

  1. Compact structure and small size, which minimizes space and piping requirements
  2. Easy to install. Since the inlet and outlet are the same size and are also on the same central line, the pump can be installed directly on any part of the pipeline, just like a valve.
  3. Easy to maintain. No need to dismantle piping for inspection and maintenance
  4. More suitable for higher temperature, higher pressure products due to its ability to handle thermal expansion

Application

Vertical inline pumps are suitable for a wide range of industrial applications (plants, mining, fire fighting, water supply, water treatment, pressurization, building systems, air conditioning systems (HVAC)) and marine applications (ballast transfer, seawater general service, scrubber systems, ships), the most important of which are water circulation and water heating. Vertical inline pumps are best suited for the circulation of hot water, as they can withstand extreme temperatures.

Key Considerations When Selecting an Inline Pump

The number of stages: There are two common in-line centrifugal pumps, one is a single-stage in-line centrifugal pump and the other is a multi-stage in-line centrifugal pump. Multistage pumps are better for fluid pressurization, while single-stage pumps are ideal for low-pressure applications

Flow rate: Flow rate is the volume of liquid that passes through a pump in a given time period. This is one of the most important things to consider when choosing an inline pump

Head: The term head is used instead of pressure in the centrifugal pump business. The maximum height at which the fluid can be pressurized

Horsepower: A commonly used unit for measuring power. The pump must have sufficient power to achieve the required flow and head

Flange: The end flanges of the pump must fit and align perfectly with the piping for full pump operation

Overall costs: Designed to help you maximize efficiency and reduction in total operating costs
