Inline pumps are a type of centrifugal pump. This type of centrifugal pump, i.e., inline pump, got its name mainly because of its structure. The suction and the discharge connection in an inline pump are kept in line with each other inside their casting. Due to this inline setting and small structure, inline pumps are relatively easy to install. Moreover, they efficiently pump fluids like water which have less or no solid particles present in it. There are two types of inline pumps, 

1. Vertical Inline Pump
2. Horizontal Inline Pump 

You can choose the one you want based on your application. 

There are various ways of applications for an inline pump, and they serve a wide range of industrial applications. Below we have discussed some important ones.

Industrial Applications of an Inline Pump

● Inline pumps are best known for water circulation and water circulation. Vertical inline pumps efficiently circulate fluids and water heating because they can also hold up in extreme temperatures; hence, they are used in boilers, cooling towers, and air conditioners. They can be used as boosters in thermal power stations or water supplies.

● Due to the high water pressure they produce, inline pumps are used in fire stations.

● Inline pumps are great for dealing with slightly hostile solutions, deionized water, glycol, etc.

● Large tanks can also be filled using inline pumps because of their rapid pressure.

● Repressurizing fluids from the tank to a valve or via a pipeline is another application for this pump.

● As inline pumps allow the flow of water without any solids, they are ideal in the agricultural sector for handling water.

● They are highly beneficial in irrigating crops.

● They are used in reservoirs, bored well, and rivers to pump water.

● Being waterproof, they are perfect for outdoor usage.

● This type of centrifugal pump is also used in the pharmaceutical and food and beverage industries. 

Inline pumps are not just restricted to their industrial applications, and instead, they are also very valuable in terms of their domestic applications. 

Domestic Applications of an Inline Pump

● In commercial buildings, inline pumps come handy in the setting of hydronic heating systems.

● They are also used in the circulation systems of hot water.

● Moreover, just like inline pumps serve in the hot water circulation systems, they are also great at handling cold water.

● Inline pumps are also used in instalments of HVAC chilling systems (air conditioners).

● They are also used in filling up tanks.

● In the case of low-water pressure systems, installing an inline pump is the best decision.

● Additionally, they also serve in the commercial supply of water. 

To sum it up, it is safe to say that inline pumps are not limited to a few applications; instead, they serve widely for domestic and industrial purposes. The water supply for industries, cities, booster systems, and isolated areas is all made possible by these small inline pumps! 

Vertical inline pumps are superior to horizontal inline pumps due to their tolerance to bearing high–temperature and high–pressure and being more effective. Just like that, they possess some advantages as well as disadvantages. In this article, we will discuss some of the pros and cons of a vertical inline pump that you should know if you are considering installing a vertical inline pump for your application.

Advantages of Vertical Inline Pumps

Elimination of Coupling, Bearing, and Need for Shaft Alignment

Vertical inline pumps do not have a coupling to align, as in close-coupled end suction pumps. The impeller is keyed directly to the motor shaft, eliminating coupling, additional bearing assembly, and the demand for professional shaft alignment.

Less Noise Pollution

Nowadays, companies try their best to avoid noise pollution. In vertical inline pumps, there is less noise and vibration than in any other pumps. This is because, due to the structure of inline pumps, the vertical shaft configuration is naturally balanced, and gravity does not pull with or against the direction of its rotation. As a result, if there is any imbalance, it will remain much less pronounced than in other suction pumps.

Space Friendly

With an inline setting in vertical inline pumps, the pumps are generally smaller in size, require less floor space, and are easy to install.

Save Your Initial Cost

Usually, inline pumps do the same job as base-mounted end suction pumps but at a comparatively lower cost. They produce the same gallon per minute and give the same head performance as other pumps. There is no need for an alignment or base to grout or the need for a suction diffuser or straight pipe; most importantly, as discussed above, they require less floor space. Keeping all these points in mind, they require an overall less installation cost.

Disadvantages of a Vertical Inline Pump

Mechanical Seal Failure

Vertical inline pumps are ideal for fluids that have less amount of particles in them. Sometimes when a liquid with a high concentration of dissolved gases is introduced in these pumps, it might be challenging to handle it. This leads to mechanical seal failure. The pump’s performance is sensitive or inversely proportional to the viscosity of a liquid.

Requirement of Pit and Bucket

Most vertical inline pumps require a pit and a bucket to process, which makes them costly to construct, especially in the case of multi-stage pumps. They also need a large headroom due to their vertical position.

Operational Challenges

Sometimes operational challenges can occur at high suction pressure due to the difficulty of balancing axial thrust with shaft designs overhanging in these pumps.

With the advantages and disadvantages of a vertical inline pump listed, it is essential to weigh the various factors and decide which are the crucial factors for your business before investing in the pump of your choice.
