Applications for Lowara Centrifugal Pumps

Lowara has been in business since 1968. Their manufacturing facility in Italy is approximately 45,000 sqm and employs more than 800 people. They are generally accepted as one of the best manufacturers of centrifugal pumps in the world.

Lowara is now under the aegis of global giant Xylem, but they still have the vision that made them successful in the first place. Lowara operates under a corporate philosophy of daily improvement, which is reflected in the amount of profits they reinvest in research and development.

This has culminated in an approach that uses modern stainless steel technology to create innovative design solutions. The result is extremely reliable and durable centrifugal pumps.

Lowara Centrifugal Pumps: Mainstays in Many Different Industries

Lowara centrifugal pumps are popular in many different industries. Their stainless steel construction makes them corrosion resistant. They can be used to move many different media, including clean water, wastewater, chemicals, food, beverages, slurries and more.

Applications for Lowara Centrifugal Pumps

One of their most popular applications is wastewater facilities. They not only transport water from businesses and homes toward wastewater facilities, but they can also handle every process in the wastewater facilities. Lowara pumps are also used for handling sewage because of their ability to handle large chunks of waste and viscous fluids.

Lowara centrifugal pumps can also be used in some surprising industries. They can handle extreme cold, so they are used in the cryogenics industry. Dairy farmers often use them to help maintain their products at the correct temperature, whether cold or hot. A variation called a turbine pump can be used to produce energy.

They are used in the food and beverage industry to move products that need to be kept safe and uncontaminated. Distilleries and chemical manufacturers use them for the same reason. There are also applications in the construction and mining industries.

Applications and Advantages of Centrifugal Pumps

Centrifugal pumps are one of the most common pumps in the world. They are used over a wide variety of applications because they have a simple design that produces high efficiency. They can handle a diverse range of head and capacity while producing a high flow rate. They rank high for ease of operation.

Centrifugal pumps have one or more impellers which are attached to a pump shaft. The impellers rotate and move the impellers against the side of the chamber. This moves the water and creates low pressure in the chamber near the inlet, creating suction on the intake side as water is pumped through the output side.

Centrifugal pumps are particularly amenable to high flow rates and low-viscosity liquids. They can be used across a wide range of scientific, commercial, industrial, residential and municipal operations.

Applications of Centrifugal Pumps

Centrifugal Pumps Applications - Swimming Pool Water

In the water treatment industry, diaphragm type centrifugal pumps can be used for metering precise amounts of liquid for the purpose of treating drinking water, boiler water, swimming pool water and wastewater. They can also be used for applications requiring high water pressure and applications where the fact that the pump does not have a seal is a benefit.

Other professions or places where such pumps are used: dairy farms, utility companies for turbines, food service and processing, distilleries, construction, automotive companies, production lines, chemical processing and laboratories.

Advantages of Centrifugal Pumps

Since there are no drive seals, there is no risk of a leak. This makes centrifugal pumps perfect for hazardous materials. Due to no drive seals, there is no friction loss, noise or wear. The fluids being pumped are completely separated from the pump drive. The result is that centrifugal pumps are nearly 100% efficient in using motor power to create pumping power.

The pump chamber is separated from the motor by an air gap, preventing heat transfer. It is impossible for liquid to seep into the motor from the pump. Friction is greatly reduced. Magnetic coupling “breaks” before high pressure can damage the pump.

Centrifugal Pump Operation: Part 2

In part two of Centrifugal Pump Operation, we are going to continue where Part 1 left off. We gave some general information and covered multiple centrifugal pump operation in series. We are going to cover parallel operation and beyond.

Parallel Centrifugal Pump Operation

Centrifugal Pump Operation - Parallel Pump

When two centrifugal pumps are operating in parallel, they are hooked to a common discharge. Unlike pumps in series, they have the same suction and discharge characteristics. Each pump has the same head, but the flow rate is nearly equal to the sum of the pumps being used. However, there is a caveat about flow rate.

Because friction is increased, two pumps that are being used for parallel operation can’t deliver the sum of their projected flow rates when working alone. The flow rates are subject to what is called the “system resistance curve.” Basically, the more resistance, the less total flow. Under less than ideal conditions, parallel operation can reach the point of diminishing returns.

One centrifugal pump operating alone will produce a higher flow rate than it will when working in parallel with one or more other pumps. If a pump is designed to be run parallel, make sure it can handle the specifications for solo operation.

Predicting Changes in Centrifugal Pump Performance

There are two factors that can cause change in performance: speed variation and impeller diameter variation.

Speed Variation

The following rules apply to speed variation. Speed has a direct influence on flow rate. The pump head increases or decreases by the square of the speed. Power absorbed increases or decreases by the cube of the speed.

Impeller Diameter Variation

The head and flow rate vary directly with the diameter of the impeller. A larger diameter increases head and flow rate. A smaller diameter decreases head and flow rate.

Avoid Cavitation

The impeller vane can be damaged by operating a centrifugal pump at too high a speed, insufficient net positive suction head available (NPSHA) or excessive suction lift. This is called cavitation. Cavitation can reduce performance and increase noise.
