In Construction? Learn About the Different Types of Pumps

Millennial Magazine - types of pumps

Many people don’t know that there are many types of pumps on the market. It is important to know what each type has to offer before you decide because not all pumps are created equally.

Slurry Pump

A slurry pump is a type of centrifugal pump that is primarily used in industries. It has an impeller that creates fluid motion to throw the material through the suction end. This type of pump works best for slurries or pastes that are very thick, viscous materials.

A slurry pump has a large variety of uses but is especially helpful in wastewater treatment plants, coal preparation plants, in the sugar industry, for mining. The last one is especially important in the dredging industry, as this is how they move the material dredged out of the water. Slurry pumps can also be used in power plants to handle ash slurries and bottom ash slurries. They can also be used in pulp and paper mills for handling black liquor.

A slurry pump is primarily used to transport heavy suspended solids which require high heat production. These materials are often easily dewatered by centrifugal action. The depth of the slurry that can be lifted is limited only by the total available suction lift, but the thickness of the slurry must also be considered, as it may exceed the pump’s maximum discharge thickness.

End Suction Centrifugal Pump

An End-suction pump is a type of rotodynamic pump. It draws fluid in through the eye at the center of the impeller and discharges it from the casing on the outer edge. There are two types: radial, in which suction is applied to rotating blades; and axial, which applies suction to one end of the rotors and discharges it through the other. It can be also used as a mixture/water-flooding pump.

Axial-flow pumps have an advantage over radial-flow pumps in that they can handle viscous fluids with higher solids concentrations, but are more expensive.

Radial-flow pumps are used when the fluid is corrosive to the casing of an axial flow pump, when the viscosity of the fluid is too high for an axial flow pump, or in situations in which a long inlet pipe would be required in an axial flow application. Another application area for radial flow pumps is the hauling of slurries where solids can damage an axial flow impeller. Radial flow pumps are more compact and lighter than axial-flow pumps.

Sewage Pump

A sewage pump is a type of centrifugal pump often used in wastewater pumping stations to transport waste from the sewer system to a treatment plant or disposal location away from the pumphouse. These pumps will move various types of liquid, such as wastewater and rainwater.

A suction strainer will be required to collect large items that might otherwise damage the pump. The pumps must be installed a minimum of 18 inches above the maximum anticipated static water level and a check valve is required for each pump. The pump will be installed with the suction strainer located higher than the discharge to avoid priming. The total lift or rise must also be considered when choosing a sewage pump.

Sump Pump

A sump pump is a type of centrifugal pump that is used to remove water from a sump or other low-lying area. The water may contain sediment, chemicals, solids, or other types of liquids. A submersible pump has an electric motor directly coupled at the bottom of the pumping chamber which turns the impeller. This motor must be connected to a power supply separately from the pump station.

This type of pump is used more often than any other type because it’s very practical, efficient, and can handle many water options like wet wells and lift stations where standing water accumulates.

However, if this pump is installed in an environment where the water level will be below normal, then you should choose a high-water alarm that can detect when the water level has fallen below the safe operating limit. This device should mount to the side of your sump pump discharge pipe so it can alert you if there’s any kind of issue with the operation of the pump.

Pumps are an essential part of many industries and the type of pump you choose will depend on your needs and the environment in which it is being used, but no matter what kind you need there should be a solution for transporting liquids from one place to another safely. Picking the right pump can make all the difference when selecting between slurry pumps or sewage pumps as they have different functions with specific applications. Do some research before deciding so you know how to best use these important machines!
